MRS20HRAD4 Uni Refrigerator - Instructions

Purchased switch and socket, not sure which had failed. Moved all frozen food to refrigerator, turned off breaker. Used nutdriver to remove two screws holding box containing switch and socket. Removed old switch and socket. Removal was slightly difficult since cabling came off both sides of the box. Installed new switch and socket and bulb. Turned breaker back on, checked light as workiing. Replaced scrrews to re-intstall switch box ( or whatever you call it ) Closed door and waited for freezer to cool. Returned all frozen food to freezer. Job Done

After reading other posts, I decided to change the defrost thermostat, so I watched the videos, and did that. It got better, but the problem persisted, and the ice was still building up in the freezer section. So I decided that the problem was with the defrost heater. I ordered a new one, that was here under 24hs (using the Fedex ground). I replaced it, measured the old one and saw that it was not passing any current at all (so it was really burnt). Now the fridge is good as new, maintaining the proper temperatures both at Freezer and Fridge sections. Thank you Parts Select ! With $ 70 in parts I was able to get back my appliance working !!!

After some troubleshooting to ensure the thermostat and heating element were working, determined that the defrost timer was the problem. With the defective part, I was able to manually advance the timer to activate the defrost cycle, but it wouldn't do so on its own. Unplugged the refrigerator from the wall. Timer is located in the refrigerator compartment at the very top. The compartment houses the cooling thermostat, the light bulb and the defrost timer. Using 1/4" nut driver, remove 4 screws holding compartment cover to top of fridge. Lower a bit to access electrical wiring. Wiring harness can be unplugged to work on the timer away from the fridge which makes it a bit easier. Timer is mounted with 2 phillips head screws. Remove screws and unplug timer from wiring. Install new timer, plug in wiring, secure with the phillips head screws and remount entire compartment.

According to the information from the parts select website the thermostat and the defrost timer where ranked number 1&2 as likely to fail and cause the condition experienced. To replace the Defrost thermostat just remove the freezer bins and the lower panel covering the evaporator. Remove the old thermostat, measure the wire lengths and install the provided crimp splices. Note: the heat shrink tubing is WAY over-sized and will not shrink to the size needed. You will need another means of sealing the wire connection. Install the thermostat and replace the panel and shelves. The timer is real easy. On my model it is located under the freezer door under the kick panel on the front. Simply remove 2 Phillips head screws, unplug the old unit and install the new one. Be sure to cycle the thermostat past the defrost cycle on the timer (rotate until an audible click is heard once for the beginning of the cycle and one at the end) so that the unit will start up when power is reconnected. This resolved my problem and the unit is working great!

One of the three top comments from other replys had similar problems, so I took their advice, since the prices were resonable, I went and replaced two parts instead of just the defrost timer. If I had to do it a second time I could probably do it all in about 20 mins.

Took a while to get the front off the drawer, but once we did, it slid right into the part you sent and YOU SAVED ME MONEY! Thank you so much!

we removed the food from the freezer, disconnected the fridge , removed the cover, the evaporater fan was running, condeser fan was running, then we checked heater with multimeter and it was ok. next step we replaced the frostimer, and defrost thermostat . and then the refrigarater was working ok, problm was the frost thermastat damaged.

I watched the video you had on-line and it was simple. Thank you so much

unplugged frig,removed bottom front cover and loosend 2 screws at bottom front left and slid defrost timer out from behind metal panel,unplugged the old and plugged in the new.frig works great.

Very simple...I followed the instructions given from someone on this site! I received the drawer within 2 days from purchase. I went on this site for tips to replace the plastic removable front piece. I just used a kitchen knife and gently pried the front away from the drawer and slid the front up and off. Then I slid the plastic front onto the new drawer. Very easy and quick.

Followed instruction vedeo from partselect. THANKS!!!!!

Exchanged the front panel of the existing drawer to the new drawer.

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

Diagnosis: used wiring diagram attached to frig and determined cause could be wiring, heater element, thermostat or timer. After completely defrosting the frig (turned it off) I removed the rear cover in the freezer and looked for an obvious problem. None seen. Removed temperature select pod from the frig box and looked for obvious problems. None seen but defrost timer appeared poorly made. Repair: Since I had no practical way of checking the defrost cycle in operation, I checked probable failures on the Part Select website and saw defrost timer as most probable. I ordered the timer. Installed it. Waited a few days to make sure the frig went through a few defrost cycles then removed the freezer rear cover. There was no excessive frost buildup so I'm reasonably sure the repair was successful.
