PLFU1778ES6 Frigidaire Freezer - Instructions

Notice ice build up on the panel in front of the evaporator coil. Unplugged freezer and removed evaporator panel. Plugged unit back in and checked fan, coil "snap switch" and heater element, all seemed to check out good. Found defrost timer stuck in the freeze position, causing frost to accumulate over the evaporator. Manually rotated defrost timer to the 30min defrost cycle and system went into defrost. Ordered defrost timer and installed (part arrived in 3 days). Freezer works great again. Too bad I ended up throwing 400 dollars worth of meat away. the fix was very simple. Will definitely use PartSelect again. Thank you.

I had to tap the screw holes with a 8/32 tap so that the screws would not bind.

After testing and eliminating the temperature control and the timer as the problem, I turned to the thermostat. I had to wait for the ice buildup to thaw and then could remove the rear freezer panel (this was the 3rd time: first, to discover the ice buildup causing the problem, second when it came back after a complete thaw and test the thermostat, and this time to put the Partselect thermostat back in). My thermostat was visibly damaged from water melting into ice and expanding the casing and eventually breaking one of the connections. I connected the thermostat connection wires (not recommended) to get by while ordering the part, which shipped faster than local repair places could get it from their warehouses, and at a fraction of the cost. I'm really impressed with partselect's fast service and all the knowledgable customers who have explained how they installed them. I now have an intimate knowledge of how my fridge works and saved hundreds in repair, or twice that in replacement. Thanks!

removed screws with from the back panel of the freezer; located defrost thermostat attached to coil with a metal clip; unplugged thermostat and replaced with the new one. Put every thing back together and it works perfectly.

I had no problems. Screws arrived sooner than expected. It was a very simple installation. Very pleased with both the product and service.

Parts Select is an excellent source for help and parts identification. I highly recomend them.
My first option was to replace the defrost timer.
After still getting ice and frost buildup in freezer I decided to replace the defrost thermostat.
Remove all shelves. Losen icemaker if applicable. Remove light cover and bulb. Remove all screws securing rear vertical cover. Carefully move back panel, disconnect icemaker and bulb assembly. carefully remove styrofoam cover at upper left and remove defrost thermostat. I tested the thermostat and found it was defective. It would not close circuit after being placed in a working freezer. Reverse procedure to replace thermostat.
This solved the problem

I first noticed my ice cream getting soft. Then 2 days later the alarm went. I emptied the freezer, opened the panels and saw no frost. I saw that 99% of issues were resolved with a defrost timer and thermostat so I ordered those. I have to say the parts came quickly and they went in very easy. My freezer seems to be in the 1% category though. It's still not cooling even though I can measure the temperature at the front of the evaporator coil is cold but by the end of the coil it's almost room temperature. I think a repairman is called for.

Spent most of the time reading and understanding the instructions. The installation went ok. Relatively easy.

Replace thermostat and show and tell made it easy.

Replaced fan. I ordered the fan and received it the following.(-:

When i found out there was no thread in brace where bolts were supposed to screw in, I panicked. I thought I would have to send part back or go to a machine shop to make a thread. I called a friend for help and he told me the bolts would make the thread if I just screwed them in. Sure enough, the bolts made the thread and then I just proceeded to instal motor and put refrigerator back together. It was simple.

Followed the sites instructions. Empty the bottom part of the freezer. Remove the screws. Move the panel out of the way. Easily remove the old part and replace with the new. Put the panel and screws back in place. The freezer works.

Pulled freezer out from where located to allow shelves to be removed.Unplugged unit, removed shelves and evaporator cover, installed new fan motor. Plugged unit up to check fan motor operation. Reassembled unit, installed shelves and moved freezer back into original location.

Upluged power pulled freezer out from wall removed the two screws that holds the defrost timer unpluged defrost timer pluged new timer in mounted new timer back with the two screws pluged freezer back in and job was complete. Freezer working fine.

I unscrewed the screws that held the old fan on, disconnected the wiring harness and removed the old fan. I pulled the blades off the motor and put it on the new fan. One thing of note, the screw holes on the new fan weren't threaded. I assume this is by design, so I used the screws to thread the holes before installing it in the freezer. Once I did this, the rest of the installation was easy, just screw it back in and connect the wiring harness.
