MRT19GNBY0 Uni Refrigerator - Instructions

Based on the diagnosis on this site I thought the 66% odds of the problem being the Defrost Timer looked pretty good, $30 including shipping versus a Sears tech phone estimate of $250-300. BINGO! Just follow the online installation instructions and don't forget to use the reset switch as described. Works like new! THANK YOU

Watched the video once. Removed four 1/4 inch screws with a nut driver unplugged the unit, took out two screws securing the timer. Replaced did all of this in about 10 minutes. It was "exactly" as the video showed and it's worked perfectly since the replacement of the faulty timer. I saved a $75.00 service call minimum and the part was more than likely cheaper from Part Select than from the repair facility. Although I'm a pretty good handy man, you would not need any experience to make this repair. The instructions are precise and the part fit perfectly.

tested the thermostat, cleaned the coils, checked seals all clean. defrost timer did not cycle so replaced it but issue not resolved. even though freezer was working while refrigerator was problematic, proceeded to open freezer panel. discovered that fan was not pushing cold air into refrigerator compartment due to ice build up in connecting tubes. cleaned ice and replaced panels to positive result

change the evaporator fan motor kit working perfect

followed the video very esay

The repair was straightfoward. The evaporator motor I received from partselect was a different model with different wiring configurations. I cut the wires from the new motor per the instructions I received with the new motor and I did the same with the wires that connect to the fridge. Once I matched the wires and secured them with electrical caps I began to put the evaporator motor to the base and started screwing the screws the way I took them off. Once I connected the wire harness to the back of the freezer and turned it on I noticed a big difference in air flow. I was surprised at how easy it was to fix my refrigirator problem. It's been a few weeks now and the fridge is cold and working like it should. Don't be afraid of this task. it's very easy and will save you a ton of money. Thanks partselect.

Instructions from partselect were very clear and probable cause made it easy to narrow things down. I have the manual for the refrigerator that shows the location of the defrost timer. Very surprised that it turned out to be a cheap and easy fix.

Removed the timer, installed the new one. Great service from part select

bottom left cornerof fridge defrost timer replaced two bolts and a wire

Unplugged refrigerator. Removed control knob and cover. Unwired control and removed same. Removed plastic tube from old capillary tube and placed on new unit. Installed and wired in new unit, making sure new unit was in the "off" position. Plugged in refrigerator, turned control knob to the first numerical setting, and was rewarded with the startup of the refrigerator compressor. Voila!

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 !!!

First I replaced the defrost thermostat, then I realized that the evaporator fan would stop turning periodically. I could restart it by spinning the fan with my finger. The fan is behind a cover in the back of the freezer. If you remove the cover and check on the fan when you hear the condenser fan in the back running. (They seem to run at the same time.) It was easy to replace the fan and the new one is more powerful than the original. The refrigerator runs fine now. Thank you for this great site. Saved me a lot of $$.

Followed the instruction video. Removed the old one. Attached the fan blade, ground wire and connected power plug. Reinstalled with 2 screws. Works great.

there were three possible problems the timer, the thermostat, or the heating element.i replaced the timer first as that is the problem 65% of the time and that did not fix the problem, i replaced the thermostat and that did fix the problem. after watching the video on line from parts select i took the back off of the freezer from the inside, defrosted the coils with a hair blower and then swapped out the thermostat which pops right off and i spliced the old connectors to the new thermostat. the heat shrink tubing that came with the part was a little to big so i put a smaller peice on each side for water proofing. that is what the cigarette lighter is for to supply heat to the heat shrink tubing.now that i have fixed that problem i may tackle the ice maker next

Removed the lower trim panel from front of fridg. and loosened two screws enough to turn it about 1/4 inch so the screw heads were in the larger holes. Pulled it out disconnected the wire connector and transfered the heat shield and screws to the new clock, connected the wire connector and aligned the screws. tightened them and job done. Has worked like new sense. Thanks Roger
