PLFU1778ES4 Frigidaire Freezer - Instructions

Used Phillips head screw driver to remove panel to expose old thermostat control. Took picture with phone to use and a guide. Replaced old with new and placed panel back o . Working perfectly! 30 minute max to complete.

First, unplug the cord, open the freezer door then unscrews 6 screws of the back cover inside the freezer. Replace the defrost thermostat. Second, on the back in the bottom you'll see the controller which connects to the compressor then unplug the wire to the controller and use a screw driver to take the controller out and replace with the new ones. That's it. Most of the time you just replace the defrost thermostat, but in my case I did try only the defrost once but it didn't work that's why I have to replace the controller too. Now it is working fine.

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.

It went exactly like your on line video. It took longer to defrost the freeze than it did to make the parts change out.

removed old broken part, 3 screws, then installed new part.....done

The repair itself total time was quick and easy. Since the original fan blade blew apart, it was only a matter of putting the new one on in it's place. This can be done by feeding the blade between the cowling and Condenser coil and applying pressure to get it on the shaft.

If your fan is still on the shaft, simply push it off and extract it the same way. Then place the new one on the shaft.

In my case, since the part would take a couple days to get, and I had food both in the fridge and the freezer, I removed and unplugged the Condenser Fan Motor and the cowling frame and temporarily spliced a small fan I had into the line for the condenser motor. This kept the fridge working long enough to get the replacement part.

Side note. Direction of airflow is towards the Compressor, and draws air across the Condenser coils.

Hope this helps someone. :)

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.

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.

Remove Ice container - loosen 2 Phillips screws -unplug electrical plug by squeezing sides- lift old icemaker up off the screws and remove - Plug in the new ice maker - place new icemaker so water inlet goes into new ice maker, slide up over existing screws and slide down - tighten screws and replace ice container

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.

Old one bad, relpaced with a new one.

First unplug freezer, then disconnected wires from timer.
Removed 2 screws from bracket holding time to freezer.
Attached New part with screws. .The mounting bracket is now part of New time. Reattach wires.
I let coils defrost and then plugged it.

Had to remove all screws on rear back cover of freezer inside, unplugged refridgerator, uncliped thermostat, unpluged thermostat. Replaced thermostat with new one in the same location, and let defrost fulley. Reassembled, pluged in, and tested. All was good. But I did also replace timer at first part of the repair so I suggest you replace both at the same time.

Removed the back panel in freezer compartment with the nut-driver. Then I cut off old thermostat connections, and spliced in new thermostat connections (repairman had already replaced defrost timer, and said not to trust connectors included on wires-they failed often). Then I snapped thermostat itself onto cooler coil. So far so good, fridge is running at 35-40 degrees a week later. Thanks Parts-Select!!!

I removed the shelves in the freezer, took out the five 1/4" screws and lifted off the cover. It was a simple matter of using a blow drier to remove all the ice, then unplugging the two wires and unclipping the thermostat from the upper cooling tube. Then clipped the new one on and reconnecting the two wires.

Works great!!!
