PLFU1777DS0 Frigidaire Freezer - Instructions

I knew from a problem years ago that the Thermostat was the likely cause so I ordered a new part and replaced it. Only need a phillips head screwdriver to remove the part and add the new one..

I first replaced the defrost timer about a week prior and it did not correct the problem. I then ordered the thermostat from partselect and within 15 minutes had the part installed. My refridgerator has been running correctly for a couple weeks.

I replaced the timer and the defrost thermostat. The defrost thermostat replacement was almost exactly like the training video here. The old part attached slightly differently. The most time consuming part was thawing out the heat exchanger, which was completely covered with ice, inside and out.

Compared to the training video, the timer took more work given its location. It was low to the ground and a bit difficult to get at around the other wires and parts. However, the new part fit perfectly. I just unplugged and unscrewed the old part then reversed those steps with the new one.

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.

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.

Remove the cardboard access cover at the bottom back of the fridge. On the left side, locate the run capacitor. Remove it by prying it loose from its socket, after first removing the wire hold down clamp. One wonders why the clamp is there, which makes it difficult to get the run capacitor out. Be careful not to disrupt in any way the copper refrigerant tubes. If you mess them up, you will have wasted your time and effort trying to repair the machine. I was lucky, since a failed run capacitor is the problem only about 12% of the time, based on what I’ve read. Hallelujah! It was the problem with my fridge.

From discussions with friends, I determined the problem might be easy to fix. The fridge made a lot of noise, but the compressor DID come on, and inside the freezer was cold, but the main fridge was warming.

After unplugging the fridge, I removed the fan assembly in the freezer (there were about 4 nuts and a couple of plugs to uncouple.

I could see right away the fan blades has broken off, but the motor looked good. The new new fan pushed easily onto the shift and fit perfectly in the housing.

I reinstalled the fan assembly, plugged in the fridge, and right away heard the new fan come on - very quietly. What was a roar became a whisper and the fridge was down to 38 degrees with a few hours.

A little difficult getting out due to restricted space, I took off the fan blade, that gave extra working room. Then it went well going back together,and it all worked as advertised. Thanks. p

I remove the old fan by pushing it off the spindle toward the evaporator and put the new one on by holding it on the right side and guiding it on the spindle from the left side, very easy task

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.

Removed shelves ,removed panel on interior back wall with Philips screwdriver ,unplugged wire terminals slid thermostat off coil ,then reversed process to complete installation.

Removed existing part, tested it, found it to be defective. OrderEd a new one and replaced the existing one.

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.

Both end caps were missing on the door side bottom metal shelf. succesfully installed no tools needed
