Magic Chef Microwave not heating: Common Causes & How to Fix
1 Magic Chef Microwave Door Switch
Most Common Solution
Repair Instructions:
Most Magic Chef microwaves have three or four door switches that ensure the door is properly closed when the Magic Chef microwave is in use. If any of these door switches stop working, the Magic Chef microwave will not start or heat up. To check if any of the door switches are faulty, you can use a multimeter to test each switch for continuity. If a door switch does not show continuity, it means it is not functioning properly and should be replaced. It is important to note that Magic Chef microwaves store a significant amount of electrical voltage, even after unplugging them. Due to the risk of electric shock, it is extremely dangerous for anyone other than a licensed technician to replace electronic components in a Magic Chef microwave, including the door switch.

4 Magic Chef Microwave Diode
Most Common Solution
Repair Instructions:
The device called a diode is responsible for changing the alternating current (A/C) power from the transformer into direct current (D/C), and it also doubles the voltage to approximately 5,000 volts. This high voltage is necessary for the magnetron to generate the heat that cooks the food in the Magic Chef microwave. If the diode becomes damaged and stops working, the magnetron will not receive enough voltage to function properly, resulting in the Magic Chef microwave not being able to heat the food. When a diode fails, it is often visibly burned out. To determine if the diode is burned out, visually inspect it. If there is visible damage, replace the diode. Alternatively, you can use a multimeter. It is important to note that attempting to replace electronic components in a Magic Chef microwave can be extremely dangerous due to the high voltage and risk of electric shock, so it should only be done by a licensed technician.
