Freezer would only run sometimes by turning the thermostat to highest position fully clockwise. Sometimes turning it full CW wouldn't turn on. Once the freezer would run on highest setting, it seemed that it wouldn't shut off. I put a thermometer inside and would read -15deg when running. +15-20deg.
Replaced thermostat and it fixed the problem. Freezer comes on and turns off automatically and regulates internal temperature around 2-5 degrees.
The hardest part was extending the coiled probe tubing and forming it to fit into clamp without kinking it.

Missing key
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".

I had a broken fan blade due to ice build up from a leaking ice maker.
1. I took out one screw on the ice maker and loosened the other two screws and unplugged and removed the ice maker.
2. Next I took out 2 screws from the bottom of the auger drive box and unplugged the wiring harness and removed the box. The wiring harness was a little tricky. The lock on the plug pushes in to unlock even though it looks like it pulls out,.
3.next you must remove 2 screws from the left side bracket that holds the auger box and remove the bracket.
4.Now take out 8 screws that hold the back panel in place and remove the back panel.
5. now your looking at the evaporator fan blade and motor. The simple way to replace the fan blade is to unplug the motor and remove it from the freezer. It just sits in with nothing holding it. The fan requires a little pressure but should pull right off. Install new fan blade and put everything back in the same order it was removed.

Freezer would not stop running and had frosted over
Pretty simple, take cover off back of freezer to access thermostat, unhook thermostat and replace with new one. It had wire hookups different from original part so had to look up that information. Turned out it did not matter which wire went on which prong.

Freezer stopped, tripped circuit breaker
Freezer was not running, I reset circuit breaker and it immediately tripped. Noticed smoke coming from behind freezer. I pulled freezer away from the wall and visually checked the compressor and a black plastic box connected to the compressor (later found out the box is called a controller) I pulled the controller off the compressor and saw that it was burnt and melted. I ordered a controller from you, not knowing if that was the problem, but I took the $50.00 chance (cost of controller) I removed the old controller from the wires by sliding a small screwdriver along a slot in the plastic next to the wire and it released the wire, I did the same to the other wire and reconnected the wires to the new controller, observing what color went to what connector on the controller. Then I plugged the controller onto the compressor and reset the circuit breaker and plugged the freezer in bingo, it started right up and has been running now for over a week.

Freezer not cooling due to icing up of coil.
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.

No problems
It went exactly like your on line video. It took longer to defrost the freeze than it did to make the parts change out.

Refigerator Not Staying Cold
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.
