DIAGNOSTIC SERVICE MANUAL
SECTION 1
AC VOLTAGE REQUIREMENTS
This refrigerator is equipped with a three-prong plug for protection against shock hazard and must be connected into a recognized three-prong receptacle.
The electrical cord should be routed in such a manner as to keep it away from the burner cover, flue pipe or other components that could damage the cord's insulation. Proper AC voltage for this style refrigerator is 120 volts.
(132 volts max. 100 volts min.)
This voltage selection is made from the control panel on the front of the refrigerator.
The incoming AC voltage is applied to terminals J9 and
J10 of the power supply module. (Lower PC board).
From there it goes to the necessary areas via the module board to perform the required function.
SECTION 2
AC COMPONENTS
If the readings do not fall within this range the heating element is defective and should be replaced.
2.2
AC POWER CORD
Disconnect the power cord from the refrigerator and wall receptacle. Using a VOM, check for continuity.
Replace the cord is necessary.
SECTION 3
DC VOLTAGE REQUIREMENTS
USE EXTREME CAUTION WHEN WORKING ON
ANY AC ELECTRICAL COMPONENT OF THE
REFRIGERATOR. DISCONNECT AC POWER

ING ANY ELECTRICAL COMPONENT. AC VOLT-
AGES COULD CAUSE SEVERE INJURY OR
DEATH.
2.1
AC HEATING ELEMENT
Disconnect the heating element from the terminals J7 and J8 on the power supply module. Using an ohm meter set on the proper scale and read across the two wires, you should get the following readings + or 10%:
USE EXTREME CAUTION WHEN REPLACING
DC COMPONENTS. CAUTION MUST BE TAKEN
IF DC SUPPLY IS NEAR LP GAS SUPPLY. DC
MAY ARC WHEN DISCONNECTING AND IF LP
SUPPLY HAD A LEAK, EXPLOSION COULD
RESULT CAUSING SEVERE INJURY OR
DEATH.
3.1
PROPER DC VOLTAGE
All Servel refrigerators require a DC volt supply even though some models are designed to operate on 120 volts AC and LP gas only. (A DC volt control circuit is required to maintain the automatic ignition.) This supply voltage should come directly from a battery.
The DC lead connections are at the back of the refrigerator. Correct polarity must be observed when connecting to the battery supply. For proper operation, the DC voltage range is 11 minimum to 15.4 maximum.

DIAGNOSTIC SERVICE MANUAL
120 V
If line voltage is present, either the 5-amp AC fuse is open, or the relay has not been activated. If the fuse is open, remove the board from the refrigerator and remove module board from cover. Replace 5-amp fuse and remount board and wire back into system.
5. AC RELAY
To check the AC relay, test between terminal 8 of the connector (P1) and terminal J4.
4. LOWER PC BOARD AC CHECK
USE EXTREME CAUTION WHEN WORKING THE AC
ELECTRICAL COMPONENTS OF THE REFRIGERA-
TOR. BEFORE REPLACING ANY ELECTRICAL
COMPONENTS, MAKE SURE THE AC POWER
SUPPLY HAS BEEN DISCONNECTED FROM THE
REFRIGERATOR. ELECTRICAL VOLTAGES CAN
CAUSE SEVERE INJURY OR DEATH.
The following procedure will help determine if the AC operation is functioning. Set the switches on the eyebrow board to the proper position (electric and AC). The
AC indicator should illuminate. If not, refer to the
INCOMING DC VOLTS. Place the temperature selector into the coldest position with the refrigerator compartment door open. The AC heater relay on the lower PC board should be activated if the refrigerator cavity is warm enough. AC volts should be present at J7 and J8.
NOTE: This is a DC voltage check.
If a voltage of less than 1 volt DC is present, then check the 5-amp AC fuse. If defective, replace.
If the fuse is not open and 1 volt or less exists on P1-8, then the AC heater relay is defective and the lower PC board should be replaced.
If DC volts are present on the P1-8 terminal, then check continuity of the low voltage harness. Also check the temperature sensor. See Section 4.6.
Another check of the AC relay is to remove the power harness from P1 and temporarily ground P1-8. You should get an audible click and 120 volts should be present between terminals J7 and J8.
120V
If not, check to ensure that 120 volts exist on the incoming cord. Unplug from board and check.

IGNITION MODULE (IGNITER)
Before diagnosing the ignition module, be sure the ON-
OFF switch is on and the temperature sensor (see Sec.
4.6) and upper PC board (see Sec. 4.1) are good.
The ignition module has multiple functions. During gas operation it performs the following:
A. Supplies voltage to ignition electrode.
B. Applies DC volts to open gas valve.
C. Senses flame through sensor electrode.
D. If burner continues to burn, it turns off spark.
E. If unit fails to light within a given time (10 seconds), it closes gas valve and lights check light (red wire).
IGNITION MODULE CHECK
A. Remove ignition module, check back of connection strip. If corroded, clean with a pencil eraser, reconnect to wire harness.
B. Check for DC volts (11 to 15.4) at connector between power supply and control module. Power will be present for 10 seconds between blue wire (+) P2-
3 and green wire () P2-4. Also check the wire harness at the ignition module. If you have proper
DC volts at this connection, replace defective ignition module. If you do not have proper DC volts, replace power supply (lower PC board).

FLAME SENSOR WIRE
The sensor electrode sends a signal back to the ignition module to inform it that a flame has been established.
To check the sensor and wire, follow these steps.
1. Set ohm meter on highest scale.
2. Disconnect wire to electrode.
3. Check for continuity between the wire and ground.
Any reading indicates a defective electrode, replace it.
4.5
FLAME SENSOR
1. Check for proper alignment to burner. Sensor should be in flame path.
2. Check for cracked ceramic.
3. Check for loose wire connection.
4. Check for carbon build-up.
Correct any burner errors, replace any defective parts.
4.6
THERMISTOR
To determine if the temperature sensor is functioning properly, perform the following test.
Remove the upper eyebrow (PC board). Disconnect the thermistor harness from the board. Using an ohm meter set on the proper scale, place one probe on each terminal point. If the thermistor is at room temperature (70 to 75°F) you should get a reading of approximately 3000 ohms. Next, place the thermistor in a glass of ice water. Wait 2 to 3 minutes. Using an ohm meter, place a probe on each terminal point. You should get a reading of approximately 9000 ohms. Normal failure for this type of device is to have a very high resistance. A reading of 75,000 ohms or higher indicates the thermistor is defective and should be replaced. A defective thermistor could cause an over-cooling on all modes.

SPARK ELECTRODE (SPARK GAP
AND CABLE)
The function of this component is to supply a spark to the burner to ignite the LP gas. Proper alignment of the electrode to the burner 1/16" to 1/8" above the burner.
To check for a continuity reading, do the following test.
1. Turn selector switch off.
2. Disconnect the wire that goes to the electrode, from the ignition module.
3. With the volt ohm meter set on the proper scale, check between the electrode wire and ground. Any reading indicates a bad electrode. Replace the electrode.
NOTE: A weak spark or an ignition cycle of less than 10 seconds indicates a voltage supply problem to the refrigerator. This should be corrected.
4.8
DC-VOLT HEATING ELEMENT
Disconnect the heating element from J3 and J6 on the power supply module. Using an ohm meter set on the
RX1 scale, read across the two wires of the heating element. You should get the following reading: (Plus or minus 10%).

These wire harnesses are color coded for easy diagnostic procedures. If the pin connectors are in question and you have to tighten them, care should be taken as these connectors are quite small and could be damaged. If damage does occur, the complete harness should be replaced.
To check the harness, you should do a continuity reading on the harness.
erator base (3-way models only). Using a volt ohm meter, remove the fuse from its holder and make a continuity check on the fuse. If it is defective it will have to be replaced. You will also have to find the cause for fuse failure. Repair the failure, replace the fuse and retest the system.
LOWER PC BOARD WIRE HARNESS
The low voltage harness should be checked for continuity. This should be done between the upper eyebrow connector and the lower PC board connector. Lack of continuity between pins attached to the same wire indicates a defective wire. Either repair the defect or replace the harness.
SECTION 5
LP GAS REQUIREMENTS
The Servel refrigerator uses liquid petroleum (LP) that is supplied through a pressure regulator at 11" WC to the main burner. Any pressure less than 11" WC can affect the operation of the refrigerator when on gas mode.
5.1
HOW TO CHECK LP PRESSURE
Hook up a manometer to the pressure test port at the back of the refrigerator. Set the refrigerator to the gas mode and start the unit. During ignition cycle you should get a gas pressure reading of 11" to
12" WC.
If the above procedure is positive and there is no operation of the upper PC board with the corresponding switch in the proper position, then the eyebrow board is defective and should be replaced.
4.12 FUSE (3A)(5A)(20A ON 3-WAY
MODELS)
Fuses are designed as a protection device for equipment and user. (Never over-fuse a circuit).
A defective fuse indicates high current draw or direct short to ground.
To check fuse, remove it from the power supply module
(lower PC board) and the 20 amp fuse from the refrig-
If your manometer reads higher than 12 inches water column or lower than 11 inches water column, the gas system must be checked. Make sure the gas system has at least 50% of the

GENERAL INFORMATION
8.1
VENTING
Installation must assure complete isolation of the living space of the recreational vehicle and the combustion system of the refrigerator. Proper installation requires that one lower combustion air intake and one upper exhaust vent be installed. Follow the proper installation information that comes with each refrigerator. The lower vent must be flush or below bottom of refrigerator.
The cooling unit must receive a continual supply of air in order to maintain proper refrigerator cooling. The air passage from the lower vent door to the refrigerator coils and from the coils up through the roof vent must be unobstructed. If air becomes trapped by obstructions, the refrigerator will start to lose its ability to cool.
Proper venting will create a chimney effect to insure adequate circulation.
It is important to block off the area above the refrigerator cabinet from the venting zone. Also, air space at the sides of the refrigerator should be minimized to prevent pockets of hot air from forming.
Without adequate ventilation and/or with partial blockage of flue exhaust, incomplete combustion (on gas operation) can cause carbon monoxide to form. Not only does the refrigerator lose efficiency but a poisonous gas can result. The roof jack opening must be centered directly above the flue and condenser. The vent must also be of proper size.

LEVEL
The Servel refrigerators do not require critical leveling such as required by other absorption type refrigerators.
Normal vehicle leveling to provide comfort for the occupants is satisfactory for refrigerator operation. This will be well within the operation limits of 3 degrees off level side-to-side, and 6 degrees off level front-to-back of the RV.
8.3
DOOR SEAL (AIR LEAKS)
These gaskets are magnetic and when the door is closed create a seal. The purpose is to keep warm room air out of the refrigerator. To test a door gasket seal, place a dollar bill between the door gasket and the metal frame. Close the door, remove the dollar bill. You should encounter some resistance. Perform the same test on all four sides of the refrigerator door. Any area that shows little or no resistance indicates a defect in the gasket. Warm the refrigerator and using a hair dryer, carefully warm the gasket in the area that did not make a good seal. Close the door and let the seal return to normal room temperature. If this does not correct the poor seal, it will require replacement of the complete door.

CRACKED LINER
A mold mark should not be mistaken as a crack in the liner. Make sure the crack is such that you can see a split in the plastic. If in fact the liner is cracked, it would be necessary to contact the company and follow their instruction on how to handle.
LINER SEAL TO FRAME
There is a seal that is applied to the liner in the area where the metal frame makes contact with the plastic liner. If this seal is incomplete, cold air can migrate out to the metal frame and cause condensation to form.
8.5
COOLING UNIT
This is the heart of the refrigerator. It creates the cold necessary to maintain stored food at a safe temperature. It is a self-contained unit and cannot be repaired if it fails. The only recourse is to replace it. If the operation of the cooling unit is in question, we suggest you check to make sure you have a proper installation, zero clearance on the sides, top and 1/2" from combustible surface at back of refrigerator. The unit should also be level. Take a good heating element of proper wattage and install it in the cooling unit heater pocket. Wire it direct to 120 volt AC. Let the refrigerator run for approximately 12 hours. The interior should be cold by that time. If not, you have a defective cooling unit and it must be replaced. If you smell ammonia in or around the refrigerator, the cooling unit is defective and must be replaced.
items. Never cover the shelves with paper or large storage containers; they restrict air circulation. Odors or highly flavored foods should always be stored in covered dishes, plastic bags or wrapped in foil. NEVER
PUT HOT FOOD INTO THE REFRIGERATOR.
To reduce frost formation in and on the freezing compartment, cover stored liquids and moist foods. Do not leave door open any longer than necessary.
The coldest position in the refrigerator is underneath the cooling evaporator fins and at the bottom of the refrigerator. The least cold area is on the upper door shelves. This should be considered when different types of food are placed in the refrigerator.
8.7
AMBIENT TEMPERATURE
This is the temperature surrounding the RV as well as the back of the refrigerator. As the ambient temperature goes up it will also raise the temperature in the area of the cooling unit. Improper venting at this point will cause the cooling unit to have reduced efficiency, therefore not allowing the refrigerator to get cold enough.
8.8
HIGH HUMIDITY
High humidity can have an effect on the amount of condensation that builds up on the main frame of the refrigerator. In some cases it can develop to such a degree that it will run off the frame. As the humidity is reduced, the sweating will decrease.
