RNB19A1-3A (2A70A) Magic Chef Refrigerator - Instructions

We tried repairing with a new switch which was very easy to install but it didn't fix the problem.

This is an easy fix, simply remove and replace. What I was impressed with is that a how to video was provided along with my part. I wish all manufactures would offer this, the video was easy to understand and you had a good view of the operation. Thanks, a job well done.

Researched this problem on the web. Disassembled the main refrigeration unit (slide out freezer floor panel). The cooling coils were completely iced up. Thawed overnight. Tested the coil thermostat with a multimeter and discovered it worked. Note that the activation temp on this thermostat is 15 degrees Fahrenheit so the ice-water bath test on many web videos will NOT work. My test was in another refrigerator freezer compartment (everyone has two, right?). When the temperature went below 15 and stayed there for 15 minutes, the thermostat opened the circuit. Further investigation revealed that the defrost heater was burnt and shorted. Replaced the defrost heater only to discover that the defrost timer was also broken. After replacing the defrost timer and testing each component thoroughly, the refrigerator is back in service. Freezer maintains about 8 F and the main refrigerator stays at about 36. The unit cycles off properly and the defrost timer is correctly initiating a defrost cycle. Further, when the defrost heater is cycled on, the thermostat correctly shuts it off once the coils are defrosted. Watch the youtube videos. Find your parts and note their specifications so you can test them properly. And good luck.

I unpluged the refrig, removed the shelves and the back panel on the freezer side of the unit. This exposed the fan motor and fan blade. I removed two screws holding the fan unit in place, unpluged the wires connecting the fan unit to power, and then removed two other screws securing the fan motor to the bracket. I removed the fan motor blade from the old unit and installed it on the new fam motor. I replaced the fan unit into the bracket, pluged the wires back into the fan motor and secured the motor to the refrig. Replaced the back panel and shelves, pluged the refrig into the wall.....easy.

After receiving the new part almost immediately,using two screw drivers, removed the broken switch from the plastic frame. Be careful not to scratch or otherwise tear the plastic...very pliable. Since the original switch was factory installed and the wires were packed in fiberglass insulation, the switch came out but the wires and clips were still in place and could not reach the new switch. It was necessary to pull them down with bent long nose pliers...used a lot of "pull" but the wires held up.Connected the switch, turned the power on and there was light! Reports from other users really took the uncertainty out of the task.

Unscrewed the right control knob. Removed the left temperature control knob (there is no screw holding it), removed one screw to rear of small panel then pried open from the rear of the small panel, there are two plastic tabs in front of the small panel holding it in place. Unscrewed the failed control unit and replaced it with the new one. Replaced the small panel and screw then the left side control knob, making sure of the alignment in the "off" position as the knob has to be pressured into a clamp arrangement on the cold control thermostat. Re-screwed the right knob into place, as well.

Well the repair was not bad the package came in real fast thank you very much. Doing the work was real hard took about an hour to do and then putting it on I do not think it stayed on good still using some duck tape to hold it and the top and bottom are real fat and will not sink on in. I do not know what to do or what I did wrong. I am kind of afraid to take it off because it might rip. Some of it ripped as I was putting it on too. Do you have any ideas of what I can do or what might be my problem? Thanks.

Sincerley,

Simply stick a putty knife between the switch and refrig wall. Pop out old swith, remove both wires by pulling off switch by terminals. Throw switch out. Put wires on new switch and push into slot and all done. Nothing to it! Took me 5 minutes if th

I have never before seen a bulb with the filament intact not light. If the bulb's filament seems intact, screw the bulb into a known working lamp and see if it lights. When screwing it back into the socket in the fridge, it takes a bit of extra effort to fully seat (until it does, it won't light!). For replacing the switch, I unplugged the unit, used a paint scraper and worked it under the switch bezel from the right side. A bit of moxie, and the switch came out. The replacement switch had a different spade contact spacing than the original. I used a pair of scissors to cut the rubber bridge between the two switch wire connectors so I could connect to the new switch. In the end, it turned out to be the bulb. NOTE: The Model TC18KL is _not_ listed! What I finally found that the number "P7803211WL" on the sticker is actually a manufacturing code. Found this out by searching, and Sears' part search came up with matches.

I tried to remove the old light switch using a putty knife and a hammer. It was hard to compress the plastic tabs to pull it back through the hole, but all of a sudden, the lights came on. I guess banging on the switch freed-up the contacts. The new switch is now a spare part in case I need it.

Viewed the viedo - it showed what to do

I had ordered some other parts for something entirely different off your website and service was great. So after almost ten years of a dark refrigerator, because of a defective switch, I decided to see if you had the part to fix it... You did and the part got here in 3 days. I had a working light switch and all the light in the world where my husband needed it most (in the fridge). It took me at the most ten minutes to replace the part. All is well now and I have a happy husband who can find the leftovers just fine. Thanks for your great service!

followed the video as instructed. Saved two repairman calls, one to find the problem, one to install. Net savings was about $130.00
