PLFU1778ES4 Frigidaire Freezer - Instructions

We were looking for a new freezer --thinking it wouldn't be worth calling a repairman. I was trying to determine the size of the freezer and couldn't find it in the manual. So I googled the model number and stumbled upon this site. Thought it would be worth a try and $12 plus shipping to replace the thermostat. Got the thermostat a couple days later, followed the video directions to replace it--not hard! Plugged it in and it is working great!!! SOOOOO glad I stumbled on your site! You saved us $700-$800!! Thank you! Thank you! Thank you!

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

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.

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!

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

just like the video show sa 1,2,3 yeaaa thanks

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.

Instructions were very good. Easy to do. Need to put in instructions, that you will NOT hear anything until about 8 hours later. Just because it is plugged in, water on...no sounds until 8 hrs later, and will hear the water doing into the ice maker.

Replace thermostat and show and tell made it easy.

I followed the You-Tube instructions, removed the ice from the compressor and replaced the thermostat with the part I received from Part Select. What I took out was a part that was very much inferior to the replacement part. The repair saved me a lot of money for a new freezer and it was not difficult to do following the video. Now the freezer runs better and quieter than ever. Thank you Parts Select.

After researching other issues found on internet about same problem, decided to replace both thermostat and temperature control thermastat before going to the repairman way. I saw the videos given on this web site, ordered the parts and when they came in, unplugged freezer and started taking apart the back cover not sure what I would find. Turns out it was just that simple, unplugged the thermastat and unclipped it from the cooling fins, unplugged the temperature control switch and then plugged both units back in. The tricky part was coiling the temperature sensor ( not that tricky). I was done in about 45 minutes but that also included cleaning out and scrubbing the bottom and sides of freezer since I had everything out anyways. Started the freezer back up and took about 8 hours to freeze ice and other food at a setting of 4, where as before I had it set on 7 and was still not keeping the ice cream cold.

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.

Remove the cover panel inside the freezer, remove and replace the fan motor (pull fan blades off old motor and push on the new one) and replace the cover.

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.

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