5139A Frigidaire Air Conditioner - Instructions

Removed old thermostat and replaced. really easy.

Wasn't sure if it was the derost timer or the heating element. Since the timer was much cheaper, I bought it and crossed my fingers.
My story is like the others. Unplug the refrigerator, snip the old wires, strip back the wire insulation, use the supplied connectors to attach the new defrost timer to the existing wiring.
Success! My coils no longer freeze up.
Only difficulty is I am a large guy, and fitting my upper body into the freezer was challenging.

First I remove the back panel which had 4 screws. Then I removed the ice maker. The icemaker is held in place by the 2 screws that requires backing the screws out just a litter, than lift up and remove the electrical connector. Used a volt ohm meter to check the resisitant in the heater element and the defrost timing switch. Both tested good and that left only the thermostat. Removed and replaced the thermastat swich. I cut the ends of the old switch and crimp the ends of wire with the crimps that came with the swict i purchased from parts select. My refrigerator is working properly and making ice like normal.

After the refrigerator stopped cooling, we determined that the problem was in the compressor area. we used a screwdriver to get the cover off and then vice grips to get the actual pieces out (start relay & overload)--they broke, but they were already broken). We went to the Home Depot site to purchase the parts, but found PartSelect to be much less expensive. Put the parts in when they came a few days later and it worked! thank you PartSelect!

Removed the old defrost timer by removing 4 screws on the holding bracket. Disconnected the wire harness. Reconnected the wire harness to the new part. Installed the new part with 2 screws on the top of the molded bracket. I am a 67 year old woman... easy-peasy. (the defost timer is located in the bottom left rear of the freezer.

Bought the defrost timer based on PartSelect recommendations, installed it and no change. Apparently the old one was fine but since the refrigerator was in a flood and this part got submerged in water I kept it rather than returning it. I looked at everything closely and realized all the mechanical functions were working properly. Rarely does a condenser coil fail so I decided to look into recharging the coolant. Bought a 1/4 inch bullet valve, a 12oz. can of R-134a and a cheap resealable can adapter with hose, gauge and R22 to R-134a adapters. After a $30. investment Bingo, after one squirt the refrigerator began to cool and after 4oz. it now works better than new. I understand that PartSelect is in the business of selling only their parts but please consider that there can be other simple problems.

tested defrost timer and heater. And then tested defrost timer with ohm test($6 at hard ware store) Closed and would not open replace and tested freezer take 30mins to get switch cold and retest.

I order another one thanks

Pulled out the freezer. Unplugged. No freezer back cover was there. The compressor start relay was in a plastic encasement attached to the compressor - wires led me to it. Removed the solid metal spring with a screwdriver and removed the plastic cover. Tried to pull out the defective relay but the freezer was so old I needed a pliers to remove it. When I put pressure on the old relay with the pliers the relay broke and came off in pieces. I then removed the wires from the broken parts and put them on the new relay. I pushed the new relay onto the 2 pins then replaced the cover and spring. After plugging the freezer in the problem was fixed.

The old defrost timer started making a screeching noise (probably bearings going out). The replacement part was a cinch to install. When I initially spoke to a PartsSelect person, they said the part number I gave them was not consistent with my old '94 Tappan Freezer. They were able to still find the proper replacement part number. The video that was on-line helpful also.

1. Turned off the cooling cycle and unplugged the refrigerator.
2. Removed all of the shelving and bottom basket.
3. Removed rear covering in the freezer section.
4. If frosted over, manually defrost coils with hairdryer.
5. Located original thermostat and after marking the wire locations cut the wires and removed the Thermostat.
6. Connected matching wires using a lighter to melt the wires together. Wrapped repaired wires with electricians tape.
7. Unable to install the thermostat in the recommended location (freezer is a tight fit) the new part was installed at the original location.
8. Replaced the rear cover and shelves.
9. Plugged in the refrigerator and set the cycle back to cooling.
10. Monitored freezer coils couple of days/weeks depending on how fast they freeze over (slots at bottom of cover) to validate if problem solved.

After removing the key from its shipping package I pushed it into the freezer locking slot and turned it to lock and unlock the lid and then removed it. I had no problems with this fix. Of course, I am an older gentleman with a lot of experience in repairs around my house,as well as other houses. I am sure that a less experienced person may have more of problem with this type of "repair".

The timer in this older unit is clearly exposed at the back of the freezer underneath the freezer compartment. It is attached with two Phillips head screws. After the screws are removed, the timer can be unplugged and the new one plugged in. The new timer has an extra flange to allow it to be used on more than one model of freezer. In order to mount the timer in this unit, you have to remove the extra flange by carefully cutting it away from the timer body, in similar fashion to what's depicted in the online video. This will allow you to mount the new timer to the mounting plate using the two screws from the old timer.

I removed the compressor start relay and replaced it with the new part. Initially it did not work. When I checked my work, I had to tighten the connector on the new part. Once I made the correction, the freezer is freezing normally again.

My fridge side had warmed up to 70 degrees but the freezer side was still cold. The coils inside had iced up. After thawing with a hair dryer, it froze back after another week. I removed the old defrost thermostat and wired the heater strip directly and turned on the defrost timer. It began melting the ice so that ruled out the heater strip being bad. I couldn't get a reading with my ohm meter on the defrost thermostat so I took a chance and bought the part. Installation was a breeze and it fixed the problem.
