freezer would not defrost
My freezer would freeze up and not allow cold air to refrigerator side. First I took off bottom face plate, located the timer on left side bottom, removed the two screws and unpluged the timer. Replaced the timer with new one. Second I removed all food from freezer. Took of back of freezer wall with nut driver. Located the thermostat which was very easy to remove. Just one clip holding thermostat. Unplugged the two wires from the old thermostat and plugged in new wires. Thanks to Partselect.com, the parts were an exact match. Very easy to do. Saved my tons of money. Freezer and refer works like new.

Freezer coil frosting up solid. Refrigerator warming
First - I asked a person familiar in ref/freezer repair for assistance. This was the hardest issue - trying to find someone to offer "free" advise. He stated that when this problem occurs it is usually one of two things: 1) The defrost timer (underneath Refrigerator - Attached w/2 screws and plug-n connector) not functioning or 2) The defrost sensor (clipped-on to the coolant line (2-press-on wires) above the main coolant coil in in rear of freezer section behind panel secured w/5 1/4" hex-head screws) not properly sensing need for defrosting. The Tech. also stated that the defrost/heat coil, which surrounds the large coolant coil in the back of the freezer hardly ever goes bad unless it is the glass/clear type coil which often crack. (Mine was the black filament type element like found in an electric oven). I check the element with an ohm meter - 27 ohms of resistance which indicated it was okay). I replaced both defrost timer & defrost sensor at the same time and that fixed the problem. Parts ordered were an exact match to originals (dispite model number changes/upgrades) and everything went very well. NOTE: It is good to have the part numbers off of each original item and know what they are called before placing your order. All fixed for less than $50.00. A service call alone would be more than this. Took about 2 hours to do, due to having to defost the iced-up freezer coil w/a hair blower. Don't use sharp objects to chip away ice, let the blower do the work - Patience and a couple of towels to absorb water is important here. Hope this helps the other do-it-yourselfers.

freezer working but refrigerator not getting cold
THERMOSTAT--First I removed the fours crews that hold the back of freezer (inside freezer) in place. I then pulled the thermostat out about 3 inches and disconnected the two wires. Plugged in the new one and put back in place. Replaced freezer back and installed the four screws that holds it in.(iIf your freezer has a ice maker just loosen the 2 screws that hold it and lift the ice maker up off the screws
DEFROST TIMER--- removed one screw inside fridge by light bulb that holds in the timer and setting knob, then took out the two screws that held in the timer unplugged the old timer and replaced with the new one put back in the two screws that holds the timer in then replaced the one screw that holds the unit in place

Freezer - Refrigerator Not Cold, Keeps Running
At top of refrigerator compartment, took out screws to cover (where temp control is) and to the right took out 2 screws to remove defrost timer and installed in reverse order. In freezer compartment, unscrewed back of freezer wall and took off completely. Removed old freezer thermostat, the body of freezer thermostat snapped onto coil and wire plugged in. Let run for 24 hrs, then made adjustments to temps, so far temps are back in normal range.

Refrigerator upper section was warm - defrost system failure
remove all freezer items and remove back panel covering the coils - about 8-10 nuts using a nut driver. The coils in my refridgerator were covered with a heavy frost - thermostat was also frozen over. Manually turn the defrost timer so the fan turns off to observe if the heating element is working (defrost timer is on the bottom front of the refrigerator on the left side). My heating element did work so I decided to replace the thermostat and defrost timer. Unplug the refrigerator. Disconnect 2 wires connecting the thermostat and unhook. Replacing with new thermostat - red and white wires that have male/female connectors and hook onto coil as before. Note that two parts with similar names were offered by PartsSelect and you really couldn't tell which was the right one - I got both but returning the unused one was very easy but cost a couple of bucks in shipping. Next, take out two screws and the bracket that holds the defrost timer in place and unplug it. Plug in the new one and screw it back in. Reinstall the back panel - throw out all that stuff in the freezer that you've had in there for 10 years and turn it back on - very simple and it worked perfectly. Very good experience with returning parts - excellent customer service.

Freezer was freezing up and refrigerator was hot
I turned the refrigerator off and took the screws from the inside back panel of the freezer. Then I took two mounting screws from the evaporator letting it pull out at the bottom a few inches. Then I removed the Defrost Heater and installed the new one. Then I put the mounting screws back in and replaced the Thermostat. Then I put the back panel back on and turned the refrigerator back on. It has been working for now.

Freezer is not working (no interior light or coolness). Outside panel says 1 f with the 'door ajar' and 'power light' lit in red. The door is not ajar and there is power to the freezer. Any advice would be appreciated!
For model number LFFH21F7HWA
PartSelect logo
Hi Judi, Thank you for the question. The messages are on the display because the temperature in the freezer is to warm. This is most likely caused by a defective defrost thermostat.You can teat the thermostat,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!

Compressor code ff 0
For model number lffh21f7hwj
PartSelect logo
Hi Ed, Thank you for contacting us. The FF code means that the temperature in the refrigerator is rising. There are some parts that you will need to check and the defrost thermostat is one that fixes the issue the majority of the time. You will also need to check the evaporator fan motor, the controller, the main electronic control board, and the run capacitor. I hope this helps. Thank you and have a great day!

My freezer is blowing cold air, but it is not getting cold enough to keep ice cream frozen. There isn't any frost inside, but the outside of the door is cold to the touch. I've noticed the freezer is running pretty much all the time and the compressor is hot. I've noticed some warping on the gasket, and with the door being cold on the outside, i was thinking it vould be the door gasket. Do you think it is this part, the door gasket, or something else?
For model number MFU20F3GW2

Hi Will, Thank you for your inquiry. If your refrigerator will not stop running, there are some parts that you will need to check to see which one is causing the issue. You will need to check the defrost thermostat, the defrost timer, the defrost heater, the door gaskets, the condenser fan motor, the evaporator fan motor and the compressor. I hope this helps. Thank you and have a great day!

Upright freezer tends to let food defrost inside freezer. However if you turn on the quick freeze button then it will run for the 24 hours it is programmed to do or when you turn off. Food frozen, no problem. If you do not do this regularly then the food starts to warm up and defrost again.
For model number 2539280412

Hello Gary, Thank you for your inquiry. We would recommend checking the following parts to fix your issue: defrost timer, defrost thermostat and defrost heater. You can test the parts with a multimeter. If you are unfamiliar with how a multimeter functions, there are YouTube videos available to assist you. Hope this helps!

Everything is running but, not cold enough and starting to defrost food... amber and red light both on outside. noticed ice on the very bottom on coils
For model number LFFH2067DW2
PartSelect logo
Hello James, thank you for your question. We would recommend testing the defrost heater, defrost thermostat and temperature control first. If there is ice on the coils at the back of the fridge by the compressor check to be sure the condenser fan motor is running. If the ice is on the coils in the back wall of the unit where the defrost thermostat is, that is a likely issue with the heater/thermostat. I hope this helps!

I asked the following question: Where is the thermostat that controls the temperature of the unit itself? Lets say i wish the temperature to be close to but not exactly 32. Maybe 37 degrees? I need to know the specific answers not just a part number to order. Thanks
