CustomerJames from Navarre FL

After getting wiring diagram off internet it was diagnosed as freezer stuck in defrost mode, temp alarm on, but fan running.

Turned gray knob on defrost timer (located bottom left back of freezer) past defrost position to verify compressor would run...it would not, but fan would run. Tested run capacitor...found borderline defective (weak, wrong value ohm meter kick). Just to be sure, removed interior shelves and interior rear and gasket to check heater at 20 ohms as OK and removed thermostat and verified contact closure after exposure in another freezer....re-installed, hooked heater back up and re-installed interior rear panel. Replaced defrost timer by unplugging 4-pin connector, then removed 2 screws that hold it to the bracket. Installed new one in reverse order. Then removed wire bail holding run capacitor to compressor plug assembly, removed run capacitor, plugged in new one. Turned on freezer......now making ice and holding cold temperature and cycling properly between freeze and defrost modes. Two problems made this repair a bit more difficult. This is the second time that defrost timer has failed...only got 3 years from last one.

Temp alarm sounding and food on top shelves partially thawed

After silencing the alarm, it seemed to be running as normal without any unusual noises, but food was starting to thaw from the top shelf on down and condensation was dripping from the roof. We were able to place most of the food in 2 large ice chests and then the rest in the freezer compartments of 2 fridges we have in the house. I then turned down the temp dial to the coldest setting and let it run for an hour or so; no change.

After researching on the internet, it sounded like our symptoms could be pointing to a defrost timer issue. I pulled the freezer away from the wall, located the timer and used a large screwdriver to slowly advance it. While doing this, at one point I could hear the compressor kick in. I pushed the quick freeze button and let it run for a while. When I checked it in a few hours, the alarm light had gone out and water that I had placed inside was frozen. We took a chance and put the food we placed in the ice chests back in the freezer. Everything was fine several hours later.

I ordered a new defrost timer, it arrived in a couple of days, and replaced the old one with it in a matter of minutes by disconnecting the wire harness from the old timer, removing the 2 screws holding it onto the bracket, screwing the new timer to the bracket, reconnecting the wires harness, and done. It's been a week or so and no problems.

CustomerJames from Biloxi MS

Freezer was not cycling and started freezing up around the compressor but was not able to freeze inside the box.

I knew that the problem had to do with the timer so I went online and looked at the schematic diagrams on Partselect and identified the part that should handle the problem. I ordered it and it arrived fairly quickly. It took a Phillips screw driver and about fifteen minutes to remove the old part and replace it with the new one. Very easy repair. It is working as it should now.

CustomerSteven from Alamogordo NM

Freezer would over temp and decrease cooling efficiency

One day my freezer's overtemp light/warning came on. I knew the compressor was working properly (as it was still running) and that there were no leaks.

I was able to research about how this freezer worked and learned of this mechanical timer on the back of the freezer. It turns on/off the defrost mode of the freezer.

I manually turned the knob on the back to see if I could get the freezer to defrost. Turns out the timer was no longer working and when I manually ran the defrost, the freezer started to freeze again.

I just replaced this part and my freezer is working like norma.. Simple as all it takes is a few screws and you are done.
