RB18FN-3AW (7B04A) Magic Chef Refrigerator - Instructions

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!

opened box,read directions,took out bad motor,installed new one.PRESTO CHANGO way to go.

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.

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!

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.
