WRT21MR7AS0 Westinghouse Refrigerator - Instructions

I watched the instructional video and did what it said.

The parts were easily replaceable. No special instructions needed. Just identify and remove and replace. I didn't know which specific part needed to be replaced (both reported to fix my problem) but neither part was very expensive so I replaced both. No special tools needed. 1/4" nutdriver and phillips head screwdriver. Repair took about 30 minutes. I did have to make an adjustment on the defrost timer (a small dial on the unit) I just set it how the old part was set. I immediately knew it was going to work when I plugged the refrigerator back in and the fan motor inside the freezer kicked on. Easy peesy...

I watched the video on how to change the defrost thermostat. I removed the back cover inside the freezer then I pulled off the old defrost thermostat and then using a pair of wire cutters I cut it off and then bared a little of both of the wires and then slid the heat sherink and wire connectors on the existing wires and then slid the other ends of the wires into the wire connectors then crimped the ends of the connectors and then tried using heat on the heat shrinks but still used rubber electric tape over it. I clipped the new thermostat were the old one was and then reattached the freezer wall cover and plugged the refrigerator back in. 24 hours later I checked the temperature in the refrigerator and freezer and both are running a lot colder.

I initially replaced the defrost timer, and later replaced it and the defrost thermostat. The defrost thermostat was the faulty component

I followed the instructions on your website, made it a simple as possible. Very tight work area sometimes fingers only, but a little patience works.
Saved at least $300. By not paying a repair person.

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.

Unplug, remove 2 screws off back panel inside the freezer. Cut wires on old one and crimped in new one. Light to melt the shrink wrap that came with it. Pretty easy.

Popped the old one out and pressed the new one in. Very easy. Pressed new one in my hands. Fits in a channel. Very easy

Remove screws from lower hinge and carefully remove the door. In my case it was the lower bearing, flip door upside down being careful to remove anything which might fall off first. I removed the door stop and then pulled the broken bearing out with pliers. Then I pushed the new one in and reassembled it.

Just pushed the grill on

Turned off fridge circuit breaker
Removed all food from freezer and put in cooler.
Removed shelves from freezer
Removed ice maker
Removed 2 hex head screws
Tilted back evaporator cover and tried to unplug connection.
Found connection was iced over with a huge block of ice coming from water inlet to ice maker
Spent several hours trying to melt and chip away ice without damaging fridge.
Finally was able to break up ice with long flat head screwdriver and hammer.
Unplugged connector and was able to remove evaporator cover.
Cut wires near thermostat and removed
Stripped wire as needed and crimped new thermostat in place.
Used heat gun and lighter to melt heat shrink. This took a long time and required a lot more heat than expected.
Reconnected evaporator cover connection and reattached cover.
Reinstalled ice maker
Reinstalled shelves.
Put food back in
Turned circuit breaker back on.

Before buying the part, I watched your video and realized it was extremely simple to remove and replace. Item was to take 7-10 days and I received it in 4. Took longer than 15 minutes because I had to move the fridge forward, get my tools and a vacuum, get a cup of coffee and get to it. Very easy and the video was exactly step by step. It took longer to vacuum all of the dust bunnies than to replace the part.

Honestly, I was in the market to buy a new refrigerator but now I believe I'll wait several more years. Thank you for your support.

The bulb has a plastic clear cover. That cover can just be carefully removed using a screwdriver. It's held in by a metal bracket. After you remove the cover. You'll just need to replace the bulb and then re-install the cover and bracket.

The knob came in the plastic package. It was the correct part. I opened the package and placed the knob on the prongs. Now it works fine.

Thanks

It went well, thank you for the fast delivery of the item
