Need photo of freezer defrost sensor, switch or thermostat

Anyone have a photo, of the freezers defrost: switch, sensor or thermostat? Also, how to check if these parts are working and how to order replacement part. Frost keeps building up even after manually defrosting. I removed the back plate and defrosted with a hair dryer twice now. After 3-weeks the frost builds up again. I have not seen any water in the defrost pan so the unit is not defrosting.

How do,I find where the defrost timer on rca whirlpool gold bottom freezer model number gb2shdxpt01

This model has a jazz board. Its electronic defrost timer not mechanical.

To determine whether u need to get a jazz board or a defrost thermostat/bimetal, you will have to run diagnostics.

To start with we need to start the refrigerator's diagnostic mode. To do this open the refrigerator door and press one or both door switches, depending on your refrigerator type. Next press the refrigerator temperature (+) button three times in ten seconds and release the light switch or switches. This should display an "S" in the freezer display and an "E" in the refrigerator display. Then press the refrigerator temperature (+) button one time to confirm that you want the service mode. You will then see a set of numbers displayed showing the software version for three seconds. (Again this control board is used on many different refrigerators.) After the software version is shown the freezer display should show "1" and the refrigerator display should be blank. Congratulations! Pat yourself on the back, you are now ready to do refrigerator diagnostic magic! Within the refrigerator diagnostic test mode there are 6 diagnostic tests:

Defrost Thermostat DiagnosticsRefrigerator Compressor & Condenser Fan DiagnosticsFreezer Evaporator Fan DiagnosticsRefrigerator Sensor DiagnosticsFreezer Sensor DiagnosticsRefrigerator Damper Door Diagnostics

You can select the test number you would like to run by pressing the freezer temperature (+) or(-) button until the test number you want is in the freezer display. Then using the refrigerator(+) button to cycle the test on and off.

NOTE: Most tests will need to be turned off before you will be allowed to move to the next test with the freezer temperature buttons.

Test#1 Defrost Thermostat Diagnostics

After pressing the refrigerator (+) button you will see ether an "O" or an "S". "O" means that the freezer's defrost thermostat is open and will not allow electricity to reach the defrost heater. An "S" means shorted or closed. The word shorted sounds bad but actually that is what you want to see if the freezer is cold. If you see an "O" (open) and the defrost thermostat is cold that means you need to replace the thermostat. The thermostat should be shorted or closed anytime it is cold and it's safe to run a defrost cycle. This test will also check the defrost heater. If ether the defrost thermostat or heater are broken or "open" and the evaporator is iced up, you will need to replace the bad part.

Kenmore 106 56666500 not staying cold intermittantly?Does this sound like a defrost thermostat problem?

Look into the freezer and at the rear wall does it have frost building like the photo HERE If yes you will need to manually defrost the freezer with a hair drier or by placing a bucket of hot water inside the freezer and closing the door. Remove the rear wall of your freezer and see if the defrost heater and the defrost thermostat are good. This is the defrost heater part number=> 2323198 Defrost Heater Assembly The defrost thermostat part number is 2319914 Defrost Thermostat If both test OK the next part is found inside the fresh food compartment and behind the control panel=> 2313172 Main Control Board I am here to answer any questions you have, Thanks Sea Breeze

My fridge part of fridge/freezer doesn't work

Post the model number of the refrigerator. Defrost freezer behind where the cold air circulates with a hair drier. (unplug power first!) Most times when a refrigerator side stops cooling it is because the freezer evaporator behind the panel in the back of freezer (most times) has become blocked by frost=> SEE PHOTO Most times the panel before you see the frosted covering the evaporator will begin to show a layer of frost building=> SEE PHOTO (Click each photo to enlarge.) Sometimes the fresh food section of the refrigerator side will warm because ice or frost will block the damper from moving that regulates temperatures in the fresh food section. Sometimes the damper is defective and sometimes the sensor that controls the damper movement is defective. For these reasons it is important that you provide your model numbers so someone knows just what type refrigerator you have to cover all of the possibilities of what may be wrong causing the warming of the fresh food section and soon the freezer section will also begin to warm. The most likely cause are the defrost control, ADC Adaptive Defrost Control, defrost heater, defrost thermostat, air damper and air damper sensors in that order. Let me know what you have and I will try to identify just what may be happening, Thanks Sea Breeze

GE Profile PCF23NG fridge side at 47 deg.

Here are some examples of the part beakdown on a=> PCF23NGTCWW_Fresh_Food_Section Parts

See the part labeled 420? That is the WR49X10091 Damper

Not sure if you are having problems with this part yet but we need to keep it in mind as a possible cause. I am leaning to a most likrly defrost heater listed as 230 and defrost thermostat listed as location 240 in the=> PCF23NGTCWW Freezer Section Parts

The defrost heater is=> WR51X10055 Defrost Heater

and the defrost thermostat is=> WR50X10069 Defrost Thermostat

I may be wrong so I need you to look at the rear wall of your freezer and see if ice/snow is building up causing air flow to be restricted to the fresh food compartment. Photo HERE if yes you do see frost buildup the evaporator will look like this photo HERE I am leaving you a service manual here=> GE Refrigerator Technical Service Manual Follow with me in the service manual to see what is causing the air flow problem for eaxample a temperature sensor or problems with the air damper with fan, I am here if you have questions, Thanks Sea Breeze

Freezer won't maintain temperature any lower than 16-18

It appears that your refrigerator is missing defrost. It will be difficult for anyone to provide photos of your defrost heater. I recommend that you unplug long enough to allow defrost to begin manually so we can get freezer door open and remove frozen goods long enough to place somewhere safe until we examine the defrost heater and defrost thermostat. At this point the only pictures will be the ones you email me. This appears to be a new breed of Profile from GE. If you would like to attempt this please let me know. The defrost heater is part number WR50X10043 but that means nothing until we do some testing, Let me Know, Sea Breeze

I have a schreiber fridge freezer. Display is showing H for fridge, freezer is ok. Can anyone help? Thanks Anne

APM6855 Built in fridge freezer If Fridge is not cooling & freezer is ok then try a defrost by switching off for 24 hrs Then switch back on. it should be OK. If this does not work it is probably the door switch faulty , this should switch on the fan when door is closed. The fan is then controlled by thermostat sensor which switches fan off/on when required.

Refrigerator side not cooling - freezer side icing up

It sounds like your defrost system has failed. There is a timing device that turns on the defrost heater(s) which may have stopped working. Or the heaters or defrost thermostat could be bad.

My suggestion is to find a different repair person who is qualified.

Freezer Icing Up

Try contacting the hotline again and ask them if the freezer has a frost sensor on it. If it does, the sensor is not kicking the thermostat to allow for the unit to defrost.
