RB21KA-4A (AG72D) Magic Chef Refrigerator - Instructions

First, watched video on Part Select Website. Very good. Pulled Appliance out from wall, Pulled the power plug, and removed the back shield covering the working parts of the unit. Found the fan and it was almost the same setup as on the video except that I could not get to one of the screws holding the motor in place so had to remove the entire bracket with the fan. Not too hard. Cleaned away dust and gunk around the site and noticed that the fan pulled air through a tunnel-like condenser coil that was packed with gunky lint...this is what probably killed the motor. I cleaned out the tunnel with the bottle brushes and vacuum and installed the new motor / bracket assembly. Then replaced the shielding around the fan and the back cover .panel. This is important because these form the channel that guides air flow throughout the condenser coils. This particular refrigerator has a barrier underneath which guides air flow from the front left to the condenser, through the fan, over the evaporator drip pan and out the right front. I cleaned all the lint and gunk from this area as well. I also made an air filter (cut from a furnace filter) and wedged it in front of the air entry section. This should keep the condenser coil cleaner over time but you have to remember to change the filter once a year. Probably should clean the condenser coil every 5 years as well. This unit has been very reliable over 20 years and may well go for another 20. Good luck with your repair.

Removed the old fan; cut the wire and spliced in the new fan and reassembled. A little over one hour. Refrig is working perfectly now with lower settings. It is definitely off much more than on now.

just had to remove the fan motor the hard thing is getting down to it

My Son who is not an appliance repairman did it for me. He had some difficulty getting the nuts and bolts loose mainly. Sorry I'm not much help other than that! I would like to compliment you on your fast service, first time ordering from you and it was for an older model refrigerator that my repairman said he couldn't find. It's working fine now and I'm a satisfied customer!

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.

Well I could what laid on the floor and replaced it but I didn't I emptied refrigerator laid it over change the motor then stood it back up actual work about three hours

I folded in half twice! and took the back off the fridge(cardboard) and took one brace off and just took the screws off the fan from the other two braces. Turned the fan enough to get at the wires for the fan and cut them off an inch from the old fan, stripped the insulation and wire nutted them to new fan. Make sure they don't interfere with the new fan and put the new fan in place put the screws in and we're making ice and cold fridge again.

It wasn't quite as easy to get to the bolts as the video showed. The lay out of the part wasn't exactly like the video either. However, I managed to put the new part in. Unfortunately, it didn't solve the problem. At first the fridge cycled on and off but after 12 hrs it started to freeze liquids again. Since the appliance was 17 years old we opted to just get a new one.

I found the condenser fan was not working so I bought a new condenser fan kit and installed it. Fixed!

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.

The kit I recieved was perfect. All parts fit and where a perfect match. I will give you an A+ in handling my order and shocked by speed of your delivery.

My husband put in in, no problem and all is well. My husband is a mechanic for large machinery/motors so installation was no problem. Thanks, better than buying a new fridge!!!

Moved fridge out from wall, unplugged power cord. Laid on floor, removed 6 screws from cover. Removed one threaded bolt to allow assembly to slide out. Removed special nut, and took fan off. Removed 3 motor mounting bolts. Unscrewed 2 wire nuts, and untwisted wires. (option 1, no ground) Vacuumed entire area around motor. Used 3 bolts to mount motor to holder assembly, and special nut to install fan. Stripped wires back about 3/4 inch. Twisted two wires together CW, and installed new wire nuts. Slid motor assembly back into slot,(keep wires away from blades) and used one threaded bolt to secure assembly. Reinstalled cover plate with 6 screws. Plugged power cord in to test air flow (out through cover vents). Moved fridge back into place. The loud whirring noise did not stop for a day; then quiet!

Removed bad motor with socket set and pliers then removed the connectors from the old motor and soldered them on the new one. Then installed new motor. Works like new! Problem Solved! Easy fix!
