MFU20F3GW10 Uni Freezer - Instructions

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 watched the videos (they really help) and followed the steps. Everything went smooth with no surprises

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.

it was great. I ordered the capacitor for my frigidaire frig and it arrived
in 3 days. plugged in the part to the compressor and my frig has been
working ever since. I spent 3 minutes ordering the part and 30 seconds
attaching it to the frig. Easy, very easy. saved myself a 75 dollar repair
visit. thanks

Unplug freezer let stand all night to defrost. Remove the tray cover which is located on the upper back area inside the freezer.( 3 twist fittings remove it ). Remove the upper stainless steel panel which is secured with 6 screws. This will drop down exposing the condenser. Note all the wires and fan will stay attached to the stainless steel panel, this panel will drop down no need to unplug anything. On the left upper side next to the condenser you will see the thermostat. Two color coded wires. Remove the thermostat and install the new one at the same location.

Replace thermostat and show and tell made it easy.

replace thermostat and timer after defrosting and cleaning out freezer. I took less than 10 minutes and now freezer has a defrost cycle that eliminates frost buildup on the coils.

inserted key and turned

thanks to all of the people who had the same problems I was able to make a quick fix on my fridge. I pulled the back cover off and found the compressor not kicking on so I replaced the start cap. and im back in bussiness.

inspected visible refrigeration lines for evidence of leaking, found nothing substantial that would cause concern, ordered capacitor and defrost thermostat simply because both are inexpensive parts and theoretically either could be causing the problem. Both parts were very simple to install especially since I am a semi-retired refrigeration man.

I replaced the defrost timer,defrost thermostat,and run cap.as it turned out the compressor went bad. I dont know the model because but the time I got this review I replaced the refer with a knew one . two weeks living out of coolers was so much fun !!!!!!!!

i order the defrost timer and the temperaturecontrol as was advised,it was very simple as reading the previous notes, pulled knob off, rerout temp metal probe, while the cover was off i clean it as much as i could and repainted the bottom with applince paint, looks good as new, very easy, whent to the defrost timer was so simple unscreewbracket, pull wire clip harness replace harness rescreew bracket, replug freezer it's good as new, saved a lot of money, i love this web site

We really didn t need to do a repair, we just ordered a freezer key that we didn t have. I must say the shipping was fast we received it the next day. It was worth the shipping charge. We will be ordering again. Great service.

Took out three shelves. Removed 9 screws with a battery powered drill with a phillip screwdriver bit. Popped off the thermostat like I had seen on the video. Put the new thermostat on. Replaced the two wires one at a time. Reassembled the unit. This was so quick that my wife told me to let her know when I wanted to fix the freezer. She was shocked that I had completed the job. I'd been in the garage less than 10 minutes. It has been six weeks. and the freezer is working perfectly.
