Does the defrost thermostat testing with an ohm meter have continuity in the non defrost state, or does it test open.
For model number 5303918214
Hi Bud, Thank you for the question, when it is cold it should read 0 for ohms, if it is warm, about room temp or warmer it should read infinity. Hope this helps!

Both sides are warm. Comp. Ohm out good,capacitor checks out good,fans work all the lights come on. The only thing I can think of is the defrost thermostat. Can I test that putting it in a glass of water to see if it opens and closes? Thanks for your time
For model number GS23HSZDC4
Hi Jose, Thank you for the question. The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. Hope this helps!

I only find frost in the fridge side and not the freezer side. Is it the problem with depfrost thermostat? Thanks for the attention.
For model number PLHS269ZCB0
Hi Andrew, Thank you for your question. I would suggest testing that part and also the control thermostat for your refrigerator as well. That part may be reading the wrong temperature inside of your refrigerator section. You may also just want to double check that the damper between your fridge and freezer as well. I hope that helps. Good luck with your repair.

My fans are both working fine, however the coil on the freezer side is freezing up, and after thawing out completely and restarting the refrigerator side works great cooling properly for a few days until it freezes up again. Does this sound like the defrost thermo. Problem? Thanks

For model number FRS23LH5DSR
Hi Terri, Thank you for your question. If both the refrigerator and the freezer section are too warm, there are some parts that you will need to check to see which ones are causing the issue. You will need to check the run capacitor, the evaporator fan motor, the defrost thermostat, the start device, the condenser fan motor kit and the temperature control thermostat. I hope this helps. Thank you and have a great day!

I got a code "high temp" , i replaced a thermostat, but still same faulted after 3 days running. Can you help me out?
For model number LFFU14F5HWC
Hi Thuan, Thank you for your question. If the high temp error code is flashing, there may have been a loss of electrical power. Make sure the power cord is plugged in. Check the electrical outlet for power. reset the the house circuit breaker if the outlet does not work. You may have a failed start relay or electronic control board. If this is the case, you may have to replace them. I hope this helps. Thank you and have a great day!

Running but not cooling off and frost in the back of the freezer
Unplugged the refrigerator. Removed the 4 hex head screws on the lower back panel at the back of the freezer. Used a blow dryer to defrost the pipes and area surrounding the thermostat. Unplug the connection from the back of the freezer, unplug the 2 wires, one that goes to the heater, one that comes from power. Unclip the thermostat from the pipe and note which pipe you unclipped it from. Cut the wires on the old thermostat midway between the plugs and the sensor. Using the supplied butt connectors, strip the wire ends on color matched wires (should be a dark blue or black) and crimp them together. Repeat with the other wire. Discard the white shrink wrapping. I wasn't able to get it small enough with a hair dryer or lighter. Plug the thermostat back into it's respective plugs. Clip the thermostat back onto the pipe you removed it from. Replace the back panel with the four screws. Ensure the bottom of the panel is set inside of the drip tray. Replace any shelving you removed. Plug the refrigerator back into the wall. Your done!

Refrigerator would sometimes freeze everything
we researched the internet with our symptoms and most sites said it was the thermostat. At $800+ for a new refrigerater, we decided to order the thermostat. Found schematics on the net, the thermostat was located in teh freezer compartment . Unplugged, removed food from freezer, removed the bottom shelf in freezer, and the back panel It was EASY to find. Cut 2 wires, replaced with new thermostat. DONE! The new thermostat came with new connecters.

The radiator was not defrosting.
The radiator was not being properly defrosted and the refrigerator and freezer could not keep the temperature. Two things can be causing this, the defrost module which defrost the refrigerator on a regular basis ($110) or the thermostat ($18). I tried the thermostat since it is very easy to do (remove cover plate inside the freezer, cut wires of old thermostat, connect new thermostat by stripping wires. Presto...however the thermostat was NOT the problem. The problem was a blown timer circuit board that controls the regular defrosting. That repair was done by a technician. The board was $110, it seats inside the refrigerator in the control panel area.

Freezer was cold but the fridge was warm. Back panel of fridge was building up frost
First of all Don't panic! you can do it and you can save a lot of $$$ if you do it yourself. A friend advice me to look it up online resources and came accross part select on YouTube .

The process:
Defrost the fridge. Take down the panels on the fridge to have room to unscrew the back panels. Once you've taken the back panel out. You will see the thermostat right away. Replace it and voila you're done.

Fridge side too cold
Most of the time was spent removing frozen food and removing the plastic clip holding one of the shelves in place. Removal of bottom panel took less than a minute. Thermostat easy to find, clipped wires a the unit and removed unit. Used included wire jackets, but not white shrink wrap. This did NOT fix the problem. This was the attempt at a 'cheap' fix. My refrigerator required the 'control box' to be replaced.
