The New Samsung SC-9670 Canister Vacuum
Tony Perkins
Regional Technical Trainer
Although they’ve been out in other markets for several years, Samsung vacuums have
just arrived in the USA this year. The new SC-9670 Canister Vacuum is now making its
2012 debut. Below are some service cautions and disassembly/reassembly tips for the
vacuum’s Flexible hose with Control Handle.
First note that this unit is comprised of three serviceable sections: the Flexible hose with
Control Handle, the Canister, and the Power Brush assembly. There is also a telescopic
wand (pipe), however, it is replaced as an entire assembly and is not serviceable.
Flexible Hose w/Control Handle
The first thing you should be aware of is that the Flexible hose has two conductor pins at
each end which carry electrical power down to the Power Bush assembly. Be sure not
damage or break them during assembly/disassembly or the Power Brush assembly will
be unusable.
Second, the control handle uses RF technology to communicate with the canister’s control board. It has a built-in RF
transmitter and utilizes two “AA” batteries to operate properly. Should the unit appear non-operational, you should suspect dead batteries. To replace them, locate the compartment access door on the front of the handle (Look for the Samsung logo) and lift the tab to release the door. Replace the batteries, noting the proper polarity, and then replace the
door. See the pictures below for clarification.

Make Dishwasher Servicing easier with a Dishwasher Extension Kit
Keith Robinson
Manager, HA Product Support
Troubleshooting dishwashers can be a frustrating experience:

Dishwashers, in their normal, under-the-counter operating space, do not provide easy access to areas that techs
need to view operations and troubleshoot problems.

A dishwasher’s overall placement in the kitchen, and the length of the hookup lines for power, water, and drainage,
can severely limit a techs ability to actually SEE WHAT IS GOING ON.
With these issues in mind, we would like to suggest a solution: An Extension Kit that allows you to operate a unit completely outside of its normal, under-the-counter location.
The Dishwasher Extension Kit’s Parts

One 5 to 8 foot stainless steel dishwasher extension supply hose.

One 6 to 8 foot 16-3 heavy duty extension cord.

A drain extension hose.

A 3/8th inch compression union.

Connection Instructions:
1. Remove power from the dishwasher by shutting off the home’s main breaker.
2. Turn off the water source to the dishwasher.
3. Disconnect the dishwasher from all its connections (power, water, drain) and then remove the dishwasher completely from its normal operating location.

If you cannot leave the drain hose connected when you remove the unit, disconnect it from under sink, and
then remove it.
4. Connect the power extension cable using wire nuts.
5. Connect the compression union to one side of extension water hose, and then connect the extension hose to the
existing water connection.
6. Connect the 1“ ID side of the extension drain hose to the drain hose of the dishwasher if required. Connect the
other side to the dishwasher drain extension hose under the sink or secure the hose so it drains into the sink.

Are Fast Track Manuals Part of Your Tool Bag?
Nicholas Webert
Regional Technical Trainer
Located on GSPN under service tips are Samsung’s Fast Track Manuals. Are you printing these and taking them with
you on each job? If you said “NO”, then you really need to read this article! Fast Track manuals are an invaluable
source of information. The Fast Track manual for a unit not only shows the faults displayed on a unit, but also explains
how to access internal controls to operate each individual part for testing. Would you drive your car without a key? Then
why would you test a Samsung appliance without a Fast Track manual? Follow the steps below to locate the manuals on
GSPN.
STEP 1. Click Knowledge.
STEP 2. Enter the model number, and then click the magnify glass.
STEP 3. Click the number below “Service Tips”.
STEP 4. Select the document labeled “Fast Track”.
Inside our Fast Track manuals, we’ve put all the tools you need to diagnose a problem. You’ll see ohm ratings, voltages,
error codes and their diagnoses, wiring breakdowns, quick tests, flow charts, installation information, and much more.
The manuals even tell you where each metering lead goes and the values you should see for parts that are working correctly. See the door lock switch example on the next page.

1. Here’s where your meter leads go.
2. Here are the testing voltages with the door open or closed.
3. With the power off, here’s the correct resistance at the lock.
Another Example
Here’s another example of how useful Fast Tracks can be. A customer tells you that their washer shakes badly when it
starts the spin cycle. Having read the Fast Track, you know that the unit has a Quick Spin Test, and that you can use it
to demonstrate to the customer how the spin cycle works. First, you explain that the unit has built in VRT (vibration

continued
reduction technology) that uses metal ball bearings and advanced electronics to locate the sweet spin spot when the
drum reaches 300 rpm. Next, you tell the customer that at that point, the unit becomes very steady and balanced. Finally, you start the “Quick Spin” mode. The washer’s LCD panel displays the machine’s rpm’s as the customer watches
it speed up. The customer will see the unit settling in at 300 rpm, confirming that it’s working correctly and that you understand the product completely! This will build customer confidence in you and the product!
To close, the Fast Track manuals are among the most valuable tools you can add to your tool bag. They are the key to
quick, accurate diagnoses of all Samsung appliances. What’s more, they’re FREE. Make it a habit: Before you run any
service call, download the Fast Track manual for that unit and print it out. You’ll be glad you did.

Troubleshooting Samsung Heated Mold Ice Makers
Wes Sirois
Assistant Manager, HA Product Support
7 Cube
9 Cube
Troubleshooting a No Ice Condition

All troubleshooting should begin with verification that the freezer temperature is low enough for ice to be produced.
A freezer should maintain a temperature at or below 1°F for proper cooling and ice making.

Verify with the customer that the unit has been on for 24 hours and the freezer is cooling properly. The freezer temperature should be 1°F or less, which can be checked by pressing the “Fridge temp” button. The display will show
the fridge section “set” temperature on the right and the “actual” freezer temperature on the left. On models with a
bar graph display, the freezer display should show the lowest bar only.

Check the icemaker sensor at the Main PCB. The Main PCB supplies constant DC voltage to the sensor. At 1°F,
the voltage should be approximately 3.7 VDC. To check the resistance of the sensor, remove the sensor harness
from the Main PCB and check the resistance. At 1°F, the sensor should read approximately 50K Ωs.

Verify that your readings are correct by checking the temperature at the ice maker sensor, which is located in the ice
maker head, right next to the last ice cube (see picture).
Sensor

Find the temperature on the conversion chart on the next page. If the resistance and voltage readings you took are
correct compared to the temperature reading, the ice maker sensor and wiring are good. For example, if the temperature at the sensor is 10.5°F, the voltage reading should be about 3.45 VDC and the resistance of the sensor
should be about 40K Ωs. A 10% variation is acceptable.

If the voltage and resistance are not correct based on the temperature, the sensor is bad and the ice maker must be
replaced.


Defeat the door open switch to keep the fans running and verify the ice room fan is sending cold air up from the
freezer out onto the icemaker.

If no cold air is being supplied to the ice room, check the ice room fan located behind the freezer evaporator cover.
The Ice Maker Does Not Fill or Partially Fills

To check the fill mode, you will need to initiate a harvest cycle manually by pressing the ice maker test button. Once
the harvest cycle begins, it will take less than 1 minute for the ice maker to complete harvesting. Watch for proper
up and down movement of the ice sensing lever at the beginning of this test harvest.

After harvest, the ice maker should take in water, filling each cube compartment. If the water level is correct, the
water components are working properly.

If the water level is low or there is no water, check for air in the system. Models with a water dispenser usually include a reservoir, which should be filled completely with water and no air. Check the water lines, water valve, fill
tube, and water filter, making sure all connections are air tight. If water fill is still too low, remove the water and try
filling again with the filter removed. The filter may be clogged and may need to be replaced.

If no water enters the ice maker, initiate a harvest cycle and check for 120 VAC to the fill valve at the appropriate
time. If 120 VAC is present, replace the water valve. If no 120 VAC is supplied, suspect the Main PCB or a loose
harness connection.
Slow Ice Complaint

Always use the minimum expectation of ice production for a 24 hour period as a guideline when evaluating a slow
ice complaint.

The ice maker should average at least 12 harvests in a 24 hour period, yielding approximately 84 to 108 cubes. Under optimal conditions, the harvest mode should occur between 60 and 90 minutes. However, when you take into
account defrost cycles, usage and ambient conditions such as temperature or humidity, the refrigerator is likely not
performing under optimal conditions and ice production could suffer. Also, keep in mind that the ice maker will turn
off via the sensing lever when the bucket is full.

Releasing the WA5471/51 Top Load Washer Door Lock
Tony Perkins
Regional Technical Trainer
The scenario: You arrive at a service call to find a Top Load washer full of musty water, clothing and, of course, the lid is
locked and will not release. Ordinarily, this would lead you to get out the big tool box and begin disassembly. However,
that may not be necessary on the new Top Load washers (WA5471 or WA5451). The door lock assembly (DC3400025A) on these models is driven by a small 12V DC motor. Knowing that and a little information about the main board
can make dealing with this situation a lot easier.
1. Locate the Main control board behind the top console cover, on the base
next to the water valve assembly, and then remove the PCB cover to
access the Main control board.
2. Locate CN3, white 6-pin
connector, pins 1 & 2,
(Brown and Black, respectively), and then insert a
small safety pin into each.
3. To release the door lock, apply a 9v transistor battery to the ends of the safety pins, (+) to the Black wire and (-) to
Brown wire. You should hear a confirmation “click-clunk”, and then should be able to open the door.
