BNT21LEH 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.

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.

1)pry out the old/defective light rocker switch with a screw driver (flat head) and pull out the cables 2)unplug two connectors at the end of light rocker switch 3) connect new light rocker into two connectors 4)push the wires inside and put back new light rocker switch

I did exactly as the video showed. I popped out the old switch, disconnected the two terminals, connected the new switch and put it back. The light now works! The refrigerator is over 25 years old and the switch works! What a great website this is. Couldn't of done the job without Partselect's help.

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.

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.

The old light fixture and socket were easily removed. This was done with the power connected, but I already knew the switch didn't need to be handled. The solderless connectors are all insulated, so I just had to be careful. The new socket would not accept the connector for the "hot" (red) wire in the fridge, due to a design change. This is, of course, why you furnished a loose 3/16 inch crimpon connector. Rather than cutting the red wire (remember, the power is still connected), I obtained an insulated 3/16 connector of the opposite gender, and a short piece of red-insulated wire from an old fluorescent tube ballast, and made a jumper. The connector I provided (male) did not fit tightly in the original fridge connector, so I put a layer of resin-core solder on my male connector. You need tight connections. If the solder layer is too thick, it's easy to file down. Make sure to heat the solder sufficiently that the solidified solder is shiny and not dull gray. I used a 100-watt gun. 20 watts would probably work too. DO NOT USE ACID-CORE SOLDER OR FLUX ON ELECTRICAL WORK! I knew the switch was good, because I had checked for voltage at the socket terminals using my voltmeter, before I ordered the socket. It read 120 volts every time the door switch was open, and zero volts every time the door switch was pushed closed. A simple voltage tester would work here, too. Be very careful if you do this test or this repair with the power connected to the fridge; there is considerable potential to find yourself touching 120 volts with one hand while your other hand is touching a perfect "ground". There doesn't seem to be any choice if you want to test the switch. You do have a choice with the socket replacement - - the jumper described above. If you're not going to use the jumper approach, cut the power! If you are going to make a jumper and are not comfortable working on a "live" circuit, cut the power.

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.

Received the part the day after ordering. Appreciated the quick service and repair took less than a minute.

I watched the video and thought "I can do this". Made some notes and then proceeded to remove the old switch and replace with the new one. Thank you.
