MFU20F3GW7 Frigidaire Freezer - Instructions

Removed the cowling with a square drive screw driver, removed the spring clip from the cover of the compressor controls with a screw driver, pulled off the old compressor start relay and replaced it with the new part. Since other problems could have caused the compressor to short cycle this was a "replace the part and hope it would work" since that would be the most common reason and it was not a very expensive part.

Looking on-line at your diagnostic for this problem, I saw the most common part to cause this problem was the start capacitor, so I purchased one & installed it with no positive outcome. I then purchased the next recommended part which was a defrost timer & installed it with no run again. Frustrated, I looked at another diagnostic web site that claimed 90% of the time the problem is caused by the cold control thermostat. I tested mine and it tested bad, so I bought a control elsewhere, since your site did not list a PN for that device. I installed the new control and the freezer started up correctly. Looking at the wiring diagram for these parts, I see the start capacitor and defrost control are downstream of the cold control thermostat, and to my mind should have been the first part recommended for testing versus the parts I bought, so I am somewhat disappointed in the diagnostics on your site, where I spent about $80 for parts that were functional.

My issue was water leaking from the door. I thought it was the gasket, so I removed the gasket and the entire panel off of the door. There was water behind it that had soaked the cardboard seal, so I left that front part off for over a week to let it dry. We determined between us and our two toddlers that perhaps the door hadn't been properly closed enough on a number of occasions, so before I bought a $100 gasket, I'd try making sure the door was shut with tape, turning the freezer on and seeing what happened. There was no water after a few days, so on another user's suggestion I purchased the $15 key and twist tied it to the freezer door. Now I am locking the door after use so we won't have leaking water any longer.

Purchased new freezer.

Replaced defrost thermostat and defrost timer on my commercial Kelvinator freezer. Took out screws inside freezer compartment that hold panel at top inside freezer.Once the screws were removed I pulled out the thermostat dial so the panel was free to drop down and expose coils to the freezer that were located in the top rear of the inside freezer compartment.The defrost thermostat was located on the top of the coil to the top left as you face the inside of the Kelvinator KFS220RHY1 freezer. Very easy unplug old and plug in new defrost thermostat. Also replaced timer located in the back side of the freezer down near the middle of the bottom of the freezer near the compressor. There were two nuts holding the timer in the back of the freezer once I took those out I just unplugged the old timer and plugged the new timer in ....very simple fix. I have only run my freezer for a week since I replaced both parts but so far all is working well.

Removed evaporator cover, unplug 2 wires to thermostat, unclipped it from the coil. Installed new themostat back the same way.

Took out screws completely then had to wedge gasket underneath. Gasket comes a little tangled in box should remove immediately and keep at room temp till ready to use.

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.

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.

Remove door remove old gasket, put new seal in dryer for 10 minutes to help it shape better then install new gasket with about 50 screws

I originally ordered an aftermarket replacement seal off intranet at half the price. It came in poor packaging & crumpled in a ball when received. After install, it would not seal & worse than the old seal that was replaced. I removed poor quality seal & returned it. I then ordered the OEM seal from PartSelect. It came in proper packaging. I kept the inside door shelving in place with two mid screws. Beginning at top I inserted sealing grove into channel of shelving working all the way around door frame. Making sure there was no crinkles or bulges at one place & it was all even. I replaced all screws ensuring not to over tighten. Close door and made sure magnetic seal pull closed to freezer & door on both sides by sliding my finger all the way around. I did not open the door for 1 hour to ensure rubber seal had taken proper shape to freezer frame. After I worked door Open/Close many times. Door seal worked perfectly every time then and now. This is a perfect example why to buy quality parts the first time.

Pulled out the freezer. Unplugged. No freezer back cover was there. The compressor start relay was in a plastic encasement attached to the compressor - wires led me to it. Removed the solid metal spring with a screwdriver and removed the plastic cover. Tried to pull out the defective relay but the freezer was so old I needed a pliers to remove it. When I put pressure on the old relay with the pliers the relay broke and came off in pieces. I then removed the wires from the broken parts and put them on the new relay. I pushed the new relay onto the 2 pins then replaced the cover and spring. After plugging the freezer in the problem was fixed.

took door of removed gasket replaced

I order another one thanks
