You can bypass the defrost thermostat the next time it stops working to see if that is the problem. Connect the two wires to each other instead of the thermostat.
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.
If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.
If the defrost thermostat is bad, it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.
The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.
If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

13 yr old Whirlpool Side by Side refridgerator model ED25PDQ DW03 quits cooling occasionally..
Sometimes for unknown reason... the cooling stops. I had Sears out.. either bad defrost timer or ? I replaced the defrost timer... still stops. I guess it might be the thermostat control which is located inside the top front chassis.
If I pound next to the thermostat panel area... the compressor starts up and works again... until it quits maybe every other day.

I have a GE Monogram model #ZISW42 side by side, with the cooling unit on top.
In the last couple of days the fridge won't cool below 42 deg.
The freezer makes ice, so I believe the freezer is 0 deg.
After removing the styrofoam baffle, on the top front, where the flap diverter is, I get a temp reading of approximately 21 deg.
The unit goes through the defrost cycle (35 min. each 10 hrs.)
I notice the tube that runs under the drain pan is a lot hotter on the compressor side, than on the ev

My side-to-side General Electric (TFX27PFSA) has ice build up on the freezer section and is not cooling the refrigerator. I am assuming it is a defrost problem. I asked an appliance repair man and he told me the price to fix it was about $250. I checked online and they sell the defrost thermostat and the defrost timer for around $25 a piece. My question is, what exactly is wrong with the defrost and what do i need to buy so that i can fix it.
The problem is probably the defrost heater WR51X443 . This part number consists of the defrost heater and defrost thermostat . Replace the complete kit . Might also replace the timer also which would give you the complete defrost system . Simple t ...

The defrost thermo reads open with my fluke meter. Evap frozen top to bottom remove thermo and brought to room temp still reads open. Trying to figure if defrost timer is bad or thermo.

GE Refrigerator Model No. TFX26KRDAWW on the freezer side will cool to 0 F and then warn to 50 F and stop cooling. The Defrost Timer and Defrost Thermostat have been replaced.

Sounds like the compressor is going out. Most refrigerators will draw less then 11.2 amps. ...

My Amana refrigerator is not cooling either on freezer and refrigerator side. The coils below the fridge was very dirty (a lot of dust bunnies). I cleaned them with a vacuum and compressed air. I ran the defrost in the recommended fashion. The defrost cycle is automated and initiated by activating the fridge light 4 times in 8 seconds the defrost heater came on and a visual inspection did not show any frost with the exception of a small amount on what seemed to be a defrost thermostat a the top

I have a Hotpoint CSX24GRXA side by side refrigerator. The freezer side started having cooling problems in that it would get too cold, so I adjusted the thermostat to warm up the freezer. Then, I noted that the center post between the two doors in front is getting VERY warm to the touch. I looked underneath, and the coils are extremely dusty, so I am going to clean them out tonite and see if that helps. I know that there are defrost heaters in refrigerators, does it make any sense that the v

My amana side-by-side SQD26V is not keeping cool. Just opened the freezer up and found ice around the coils (back part of freezer). My husband is using a hair dryer to get the ice off the coils.Where do we go from here? If it's a defrosting problem (timer, thermostat,etc) how do we pin point it and fix it?
First off make sure that the drain on under the coil is cleared, then when the ice is gone and you turn the unit back on the coil should first get good and cold before the fan tries to come on . you will have to temporarly put the cover over the co ...

Refrigerator stopped cooling. Compressor not turning on...No clicking or switch noises heard when attempting to actuate thermostat control- Fan does turn on and run when controlled by thermostat. Can also control fan by actuating pot in defrost timer. Do not hear "any" switch noise at compressor relay - even when attempting to control by actuating thermostat or defrost timer.
There was no warning when fridge stopped cooling - no compressor noise or other odd sounds.
First, check to see if the light comes on or if there is any fan, motor, or other sound coming from the appliance? If so, the refrigerator isn't really completely stopped--go to the specific problem you are having. If not, try adjusting the thermosta ...
My ge side-by-side refrigerator/freezer isn't cooling. It started on the refrigerator side and now both sides are losing cooling capability. There is ice build up on the lower back wall of the freezer. Sounds like something with the defrost from what I've read. One guy told me I needed an Ohm meter to check the defrost thermostat and the defrost heater for continuity and whichever one reads "open" needs replaced. Does this sound right?
Yes that is right. Turn the Refrigerator off/ unplug it. Remove the rear panel of the freezer and thaw out the coils with a fan or hair dryer. \015\012\015\012The most common problem is with the defrost heater. Using an ohm meter check ...

We just replaced the defrost timer on our Kitchenaid built-in 48 inch refrigerator Model #KSSC48MHS00, on Monday. Now it seems to be cooling properly, but is still barely making ice. We removed the top front grill on Wednesday, and then it made little ice, as if it's too warm with it in place. It still isn't working optimally. The freezer temp is now about 20 degrees, and the fridge still seems like it's not cold enough, set at Level 4. Could there be another thing that may be going out?
Hello.. Put the freezer at it's coldest setting. Within 24 hours you should have a bin full of ice. If you do not, you may have gotten the wrong timer, or a faulty timer. J. ...

I have a ten year old KitchenAid Supra side-by-side refrigerator, model #KSSS4QDK05. The freezer appears to periodically get stuck in defrost and not come back out. One relay switch and two defrost timers have been replaced and same behavior. If I advance the timer a full cycle, the freezer restarts. Repair guy is convinced its another fault timer. Are we barking up the right tree here or could this be an electrical problem, a thermostat issue or some other issue?

Kenmore model #10656539400 works properly on the freezer side. the refrigerator side is not cooling. It will cool once the ice build up on the condensers is melted off using a hairdryer. I have changed the damper. The online suggestions are to replace the defrost thermostat, defrost control, or the defrost heater. What is the most likely problem.
