For Whirlpool Refrigerator Defrost Timer (Part Number: OEM17955633)

1 Answer

Eric, Based on the partial information you supplied, the timer motor black loose wire will attach to terminal no.2. Wiring should be identical to Procedure 2, pg.3 of the instruction sheet #482494. Black wire attaches to terminal #1, Pink wire attaches to terminal#2,Red wire attaches to terminal#3 and Orange wire attaches to terminal#4.

Hello Luis. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the evaporator coils in the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Russ,

When you open the refrigerator door and looking at the bottom right side of the control panel there will be a hole there. If you put a flat blade screwdriver into that hole and turn until you hear a click. At this point the fans and unit should turn on. This issue is most likely caused by a stuck defrost timer.

Dennis,

Without the proper model number it would be difficult to say if the W10822278 will work for your unit. With the unit being a coldspot which is made by whirlpool it is a good likelihood that it would work but without the model cannot be for sure. The model number is normally located on the inside of the refrigerator compartment or at the bottom of the door around the frame.

Mark for Model Number KItchenaid KSSP48QJS00

Hello, My old defrost timer only advances while in defrost mode or when the compressor/fans have stopped as a result of the cold control thermostat being satisfied. When the compressor is running, it does not advance at all, and I have confirmed this with pencil marks. So, it can potentially take several days to a week for the unit to go into defrost mode on its own (only as a result of the cold control being satisfied). I just purchased the universal defrost timer model 482493, and cannot locate the tech sheet for my refrigerator, so for my unit, should I put the loose wire on terminal 1 or 2? Is my unit a continuous run or cumulative run compressor? Thanks, Mark
