Dacor Serial Number Format:

**Prior to the 38th week of 2002 the serial number format was: FC2371234

In 2002 Dacor changed the serial number format slightly to accommodate additional product line growth by adding two (2) characters each for product code and revision and two (2) digits for the year of manufacture.

**After the 38th week of 2002 and current the serial number format is: F-C-02381234

A dash was added to separate the two codes - so that a serial number ABC representing product type AB at revision

C could not be confused as a product type A at revision BC. There is also a dash added between the revision code and year of manufacture. The year code was increased so a unit manufactured in 1992 would not be confused for a unit manufactured in 2002.

Old Format: New/Current Format:

First Letter = Product Code:

A = Accessories

B = Blowers

C = BBQ Carts

D = Dishwashers

E = Electric Modules

F = Ranges

G = Coffee System

H = Hoods

J = Electric Ranges

K = Gas Ranges

L = Integrated Hood Liners

M = Metal Cooktops/Gas & Dual Fuel (i.e. SGM and PGM)

P = Wine Coolers

R = Raised Vents

S = Epicure Cooktops

T = Electric Cooktops – Ceran

V = Wall Ovens

W = Warming Ovens/Drawers

Second Letter = Revision Level

New products always start out at revision “A”. When ever a change is made to a product in Form, Fit or Function the

Revision Level will change. A to B to C etc… (letters I and O will not be used).

First number(s) = Year Manufactured

Old Serial Number Format Example: VB7121234 = Unit was manufactured in 1997.

New/Current Serial Number Format Example: V-B-07121234 = Unit was manufactured in 2007.

Second Set of Numbers = Week Manufactured

Old Serial Number Format Example: VB7121234 = Unit was manufactured in the 12 week of 1997.

V-B-07121234 = Unit was manufactured in the 12 th week of 2007. New/Current Serial Number Format Example:

Last Four Numbers = Unit Number

Old Serial Number Format Example: the 12 th week of 1997.

Dacor Classic Wall Oven and Range Fault Codes

Wall Oven Models: CPS/CPD, CPTS/CPTD, ECS/ECD, PCS/PCD, MCS/MCD Single & Double Ovens, 27” & 30”

Range Models: PGR30, RSE30, RSG30, RSD30, ERD30-60, ERDE36-48 MRE, MRES30, EGR30, ERG30-36

-F0- Shorted Or Jammed Input Device

This failure will appear if a shorted or jammed input device is defective. Possible causes include shorted wires or a defective membrane switch.

-F1- Alarm “System Watchdog Circuit”

ERC Self-Diagnostic circuitry has detected a failure in the bake/broil system. Any portion of the ERC, relay board, touch pad, heating elements and related wiring may be at fault.

How to diagnose/repair potential cause:

Step 1: Disconnect membrane from ERC. If an F-1 alarm is not activated within 30 seconds, check membrane function test points with an OHM meter. (refer to page 20 of the Diagnostic Test Manual) If the membrane test switch fails, replace membrane. If membrane test is good, continue to step 2.

Step 2: At ERC check for 24 VDC between J2 pins 1 and 3 for upper/single ovens or J5 pins 7 and 10 for lower ovens

(when lower oven is not in a cooking/clean mode) **Note: F-1 must be showing in the ERC/Clock Display. I you read 24

VDC at those test points, replace ERC

-F2- Alarm Heating Mode High Temperature

Is activated when the ERC senses a runaway heat condition or when the temperature exceeds “runaway limits”. The ERC will beep until the cancel or another function is selected. If the alarm repeats the F2 alarm check the oven sensor and wiring after first checking for a stuck relay. If alarm goes away verify the oven will complete a clean cycle without any type of failure.

-F3- Alarm Shorted Oven Sensor

Occurs when the ERC senses a short circuit in the oven temperature sensor for 16 temperature conversions in a row. F-3 will appear in the digits and a beeping will be heard. If the alarm does not go away after pressing the cancel key check the sensor and wiring. **Important Note: This test will only be performed while a cooking operation is being attempted.

The F3 alarm will not be displayed in the time of day mode.

-F4- Alarm Open Oven Sensor

“F4” will be displayed along with a beeping if the ERC determines an open oven temperature sensor circuit for 16 consecutive oven temperature conversions. **Important note: This test will only be performed while a cooking operation is being attempted. The F4 message will not be displayed in the time of day mode. **Important note: If the oven sensor is open the bake modes cannot be activated. The controls will be non-responsive. Look for this failure, as at first appearance you may suspect the ERC or selector instead of an open sensor. A strange number may also appear in this failure mode.

-F5- ERC self-diagnostic failure

Replace ERC.

-F6- Alarm EEPROM Checksum Error

The brain of this oven (so to speak) operates a series of software commands. These commands control the various features and functions of the oven. A numerical value has been assigned to each function or operation. The numerical values can be added up - this is the check sum operation. Every time the system is powered up and after each clean cycle the system performs a check sum and compares the value to the value programmed into the software. (stored in memory.) An EEPROM check sum error or F-6 alarm occurs when the values differ. Only the time of day and timer operation will operate. If you receive a F-6 alarm replace the ERC.

-F7- Alarm Door Lock Enabled Above Temperature

“F7” will appear in the digits and a beeping will be heard if a failure in the clean lock/ phase circuitry is detected for 16 seconds in a row. Check the door lock switches and door adjustments.

-F8- Alarm Door Locking Switch

Occurs when operating the door lock motor if the motor runs for two minutes without seeing the phase switch change positions. This failure will normally occur only when a clean mode is started. If it occurs check the door switches and wiring.

Renaissance Induction Range - Induction Generator Technical Features

Renaissance Induction Range Models: RR30NS, RR30NIS, RR30NFS & RR30NIFS

 Induction Generators:

Each Induction Generator Assembly consists of two burners (front and rear) and each operates as a separate circuit. Left and Right side Generator Assembly, Touch Control, Ribbon Cable and Wiring are separate but identical which will assist in your diagnostic procedure.

So, essentially there is two of everything. Utilizing “Process of Elimination” tactics, a Technician can easily and quickly diagnose failed components using functional components from the working

Generator side.

 System’s Check:

When power supply is turned off and then turned back on the Induction Cooktop Generators will go through a “system’s check” process. This can be observed on any unit by viewing the Power Level LED indicators. The Generators will beep and the Power Level LED will count up from 1 to 9 then go blank.

 Error Codes:

Error Codes will not be displayed to the user, but will be stored for later retrieval by Technicians.

The Generator may continue to operate through some very brief error conditions, or the generator will shut down when the error condition persists. When the Error Codes are called up, the 7-segment,

Power Level LED will alternately display “F” and a numeric error indicator at ½ second intervals. A

“System’s Check” (described above) will reset any Error Codes as long as the condition has been remedied.

 Safety Features

 The generator will reduce wattage when the glass temperature reaches 300ºC. The wattage reduction will keep glass near but not over 300ºC to prevent oil fires and protect during dryboil.

 When pot is taken off of the inductor while in use or if inductor is turned on with no pot present, the inductor will de-energize and 7-segment LED will blink on its current setting for 30 seconds then turn off. If the pot is placed back on the inductor within 30 seconds the inductor will energize and the LED will stop blinking.

 The inductor will not energize if a small utensil (such as a knife or wedding ring) or an unacceptable pan (such as aluminum) is placed on the inductor instead of a steel or iron pot.

 The On/Off LED will light up whenever the associated inductor is energized.

 The Hot Surface Indicator (HSI) LED for an inductor will light up when the glass temperature reaches 105ºC and will extinguish when the glass temperature cools below 65ºC.

 Selecting Proper Cookware:

 Always use utensils that have flat bottoms. Use utensils that best match the surface unit size

(smaller utensils on smaller surface units) and are a minimum of four inches in diameter.

 Use medium to heavy-gauge metal cookware with flat and smooth bottoms. Also choose cookware that closely matches the diameter of the cooking zone. Use utensils with tight fitting lids to retain heat, odors and steam.

 There will be some variation in the efficiency of the pots being used. All brands do not behave in exactly the same way since the different metals used conduct the electromagnetic waves from the induction elements differently. o Compatible Cookware: Stainless Steel with metal bottom, Enameled Iron or Steel, Cast Iron o Non-Compatible Cookware: Copper, Glass, Aluminum, Pottery

Renaissance Induction Range – Cooktop Error Codes

Models: RR30NS, RR30NIS, RR30NFS & RR30NIFS

 Error Codes will not be displayed to the user, but will be stored for later retrieval by a Technician.

 The Induction Generator may continue to operate through some very brief error conditions, or the generator will shut down when the error condition persists.

 When the Error Codes are called up, the 7-segment, Power Level LED will alternately display

“F” and a numeric error indicator at ½ second intervals. The Generator Fan will activate.

 Error Code Cycle and Fan will automatically cancel after 10 seconds.

 When condition is corrected and unit power supply is turned off and back on, the error code will be eliminated. If condition was not corrected, the code will reappear/reinitiate.

Note: Each Induction Generator Assembly consists of two burners (front and rear). Left and Right side Generator Assembly,

Touch Control, Ribbon Cable and Wiring are separate but identical which will assist in your diagnostic procedure.

The Cooktop Error Codes may be accessed as follows (16/22 Generator):

Touch the Left or Right side (front and rear zone) “HIGH” Preset Keys and hold for 6 seconds with the generator in

Standby (powered but no zones running). The last two Error Codes produced by the generator will be displayed in the

Power Level Display.

30” Models: ID30, ED30SCH, ED30SCP, ED30SBK & ED30SBR

Factory Test Mode:

The Factory Test Mode, or FTM, is run on each unit during final QC to ensure that all of the components are operating normally. The FTM runs the unit through an abbreviated wash cycle and checks various sensors for response and is a valuable diagnostic tool. By knowing the timing of the FTM (shown below), a technician can check for operation of the component in question at the expected time.

MAKE SURE THAT THE UNIT IS SAFE TO OPERATE, AND ALL PLUMBING

CONNECTIONS ARE MADE PRIOR TO RUNNING THE FACTORY TEST MODE.

To Enter the FTM:

1. Press the SECURE key for three (3) seconds. Then press the SECURE key again for three (3) seconds to exit the secure mode.

2. Press DELAY and SANI RINSE keys simultaneously to start the factory test mode.

3. Close the dishwasher door. Be sure to close the detergent dispenser prior to initiating the FTM to check for proper operation.

4. All LED’s on the dishwasher will turn ON for about 15 seconds then turn off.

5. The factory test will begin. Use the timing chart below for expected operation timing of the component in question.

If during the FTM one of the electric components fails to operate at the scheduled time, it is likely that either the component has failed, the wiring has failed or the Power Board has partially failed. Start by checking the component in question and working back to the Power Board. Use extreme caution when working with live components.

After test has been completed, press CANCEL key once to exit from the factory test mode. To exit the factory test mode at anytime, press the CANCEL key once.

If the FTM has completed without error, a solid green light at the bottom of the door (ED model only) and three beeps will signal that all the major components are operating correctly.

Below is a timing schedule for the factory test:

Service Test Mode

There are several test modes available through the diagnostic system. Use of these test modes can greatly decrease the time needed for troubleshooting. It is to the service technician’s advantage to be able to perform many tests in a very short period of time.

Within the Service Test Mode the controls have alternate functions. The FREEZER up and down buttons (arrows) will move to the next or the previous service test. If you are at Service Test 4 and press the FREEZER up arrow you will move to Service Test 5.

The REFRIGERATOR up and down arrows will move you through the service tests ten steps at a time. If you are at Service Test

4 and press the REFRIGERATOR up arrow you will move to Service Test 14.

The POWER INTERRUPT button will activate the selected Service Test. At every test, after selecting the test number with the up and down arrows, you must activate the test using the POWER INTERRUPT button. In many cases the display will change and provide you with additional information for that particular test. To end a test and return to the test selection menu, tap the POWER

INTERRUPT button again.

To enter the Service Test Mode, the door switches must be held in the door closed position. It would be easiest to tape the switch in the closed position.

Tap the POWER INTERUPT icon three times in succession. The system will switch to the service mode and show the current mode as NORMAL or no in the fresh food temperature display. If the system shows a different indication this indicates that the

unit was not in the normal operating mode.

Pressing The FREEZER up arrow will change the display to Sh. This is the Showroom mode. If the Power Interrupt button is tapped at this point, the system will be in the showroom mode. While in the showroom mode, the lights and display operate but the cooling system does not energize.

Pressing the FREEZER up arrow again will change the display to SE. This is the entrance to the SErvice Tests. Tapping the

Power Interrupt button will place the unit into service mode and the display will change to 00 00 with the word service illuminated in the display.

From this point forward the up and down arrows are used to move forward or backwards through the Service Tests. The Power

Interrupt Button will activate the service test.

If the service mode starts at any location other than 00 00 it is an indication that the Service Tests mode was not properly exited when last serviced.

Service Test 01 – Software Revision

This test will allow you to view the current software version installed on the refrigerator. At the current time there is no method to update the software in the field. Pressing the Power Interrupt Button will display the current software version. Pressing the Power

Interrupt Button will return you to the previous screen.

Service Test 02 – High Ambient Override

This is not really a test but a system setting for special operating conditions. By activating the High Ambient override you will alter the temperature control programming. This setting should only be used in cases of high temperatures and high humidity.

Pressing the Power Interrupt Button will activate this setting. When activated the WORKING lamp will illuminate. The working lamp will return to normal operation when you exit the Service Tests Mode.

Upon reentry and selecting Service Test 02 the lamp will indicate whether the High Ambient Override is activated. Pressing the

Power Interrupt Button will deactivate the High Ambient Override.
