Refrigerator Thermostat Assembly WP2198202

Compressor start relay would cycle several times before compressor would come on. Replaced start relay and defrost timer assy. Operated more consistently however not completely reliable. Ice would begin to melt. Noticed that if you would cycle the temperature control the compressor would start again and operate for several hours then not cycle again. Jumpered temp control and operation was continuous and reliable. Replaced cold control thermostat. Operation now normal. Suspect high resistance in switch caused start relay and timer contacts to arc. Small amount of carbon noticed under temp control...

Was pretty simple just take the knobs off pull off the face plate remove a few screws and drop the whole shelf down. then a few more screws down the side to the back of the fridge. Pull the sensor wire out of some styrofoam and pull off the plastic coating and slide it over the new one and install it in reverse order from taking it out. Works great now and i have ice everyday :)

I removed both plastic knobs from assembly faceplate. Then I loosened the screws holding thermostat housing to upper cabinet of fridge. Following this step, I loosened the screws of the thermostat to remove it. Next was the removal of the plate and vent pieces holding the thermostat wire sleeve in place. After removal of thermostat from sleeve; all steps were reversed and unit was up and running normal (cooling) with no problems. "Ahh, it's nice to have cool again "

First I removed the cover plate over the cover over the thermostat, by snapping it out. Then I removed the four screws holding the cover over the thermostat in place. Next I removed the screw, which held the cover over the thermostat sensor. I then removed that cover and the unit, which exchanges air, flow between freezer and refrigerator. I then removed the two screws, which held the thermostat in place. I then removed the thermostat with the sensor and the white tube, which covered it. Then I removed the white tube from the sensor.

To install the new thermostat I first inserted the thermostat sensor into the white tub. I lubricated the sensor with a very small dab of Vaseline. Then I placed the sensor unit in the unit, which exchanges air between refrigerator and freezer. I next reinstalled the unit, which exchanges air between refrigerator and freezer. Then I reinstalled the cover over the thermostat sensor. I then installed the thermostat with the two screws, which held it in place. Then I reinstalled the cover the thermostat with the four screws, which held it in place. Last I snapped the cover plate in place.

Remove the knobs and faceplate to get at the screws behind it. Removing the sensor is a bit involved but everything else is fairly straight forward. See other postings for description / order of operation. Replacement took less than 30 minutes.
Works great now!

Turn off the fridge and unplug the power. Inside the refrigerator unit, remove two plastic panels extending from the front to the rear cooling vent by unscrewing two screws. Gently unhook the thermostat tube from the rear vent.

On the control panel, gently pry off the two control knobs and the front control panel. Remove four screws to drop down the control assembly. Unplug the left electrical connector and unscrew the lever control arm being careful not to bend it. Disconnect the right side electrical connector and you can now remove the control unit to a table to easily work on it.

Undo two screws to remove the thermostat bracket. Undo two more screws to remove the thermostat assembly. Install the new thermostat and reverse the process just described. It takes about 15 minutes if you know what to do ahead of time. You will have to reuse the plastic tube that covers the thermostat sensing tube.

The fridge side would freeze everything regardless of setting. First, unplug the unit. Remove control knobs and pry off the face plate which is snapped on. Remove the four nuts holding the control box to the top of the fridge. Note there is a mettle rod and the thermostat sensor lead inside a clear plastic tube leading from the control box to the back left corner of the fridge. Remove their cover (one screw). Under this cover in the back is the vent assembly screw. Remove it. On the freezer side, you also have to remove the light cover (snap on) and the vent cover behind it (one screw). This allows access to remove the vent on the fridge side. Squeeze the tabs on the vent(freezer side) that lock the vent in place and push it through to the fridge side. Now disconnect all wire connectors between the control box and the fridge. They have locking tabs that have to be pried out to release. Remove the two screws holding the thermostat to the control box, and one at a time transfer the wires from the old stat to the new one and mount the new one in place. Snap the old thermostat sensor lead out of the vent assembly, straighten it out and pull the plastic tube off. Put a lubricant on the new stat lead to ease in inserting it into the tube. Do not kink the lead. Re assemble in reverse order, plug up the fridge.

The wife found if we tapped the knob for the cold control the appliance would turn on. Upon further inspection I found what looked to be carbon particles under the part. I found the part easily with partselect.com, ordered it, installed it and its like we have a new appliance.

tested thermostat and defrost time but both tested as working...called a repairman who came in and said they were both working...got annnoyed for not trusting myself. Repairman did say that he had seen defrost timers simply slow down, allwoing them to tesat as good but not actually working correctly. I ordered both the thermostat and the timer to cover all bases...actual replacement was simple.

Being a jet mechanic I had to familiarize myself with refrigerators, then after 2 or 4 hours of online studying, opened the door pulled the temp knobs of, removed the panel by gently prying the top of the panel out,then up and out with it. I found tapping on the thermostat shaft or wiring connection started the compressor, verifying my belief it was the thermostat. Don't mess with wiring if you don't know exactly what you are doing and unit is plugged in, you will electrocute yourself!!! I received the thermostat, UNPLUGGED THE UNIT from the house wall outlet, took one screw out of the upper inner wall at the very top to remove cover, one screw at the back top to remove the other cover (at the control vent) for access to remove sensor, then removed 4 screws , 2 front, 2 underneath to drop the housing for defrost timer, etc., and then took 2 screws from thermostat, unplugged wiring from thermostat (3 wires, be sure to put them back on the same place in the new thermostat). Remove old thermostat, slide plastic cover off sensor and slide back onto new thermostat sensor. Be careful not to kink the line or bend it to sharp you will damage it, (use gentle curves when bending it,) and re assemble everything in reverse order. This took about me 15 or 20 minutes start to finish. Plug into wall and watch thermometer to verify success.
