Could the main control board be defective?
Although it’s not a common cause, a defective main control board could prevent the microwave from working as well. Since it’s difficult to test a control board accurately, you should confirm that the fuses, thermoprotector, and door switches all have electrical continuity and are functioning normally before you consider replacing the board.
How to tell if microwave door switch is faulty?
Most microwaves have three or four door switches that allow the appliance to start or heat once the door is fully closed. A faulty door switch will prevent the microwave from working even after the door has been closed. As with the fuses and thermoprotector, you can test each door switch for continuity to determine if one has failed: 1 Two-terminal door switches will either have continuity before the switch is actuated or after; three-terminal door switches will have a “common” terminal, a “normally closed” terminal that provides continuity before the switch is actuated, and a “normally open” terminal that provides continuity after the switch is actuated. 2 For two-terminal switches, touch the black lead to one terminal and the red lead to the other terminal, then actuate the switch. If the meter display shows zero Ohms of resistance, the switch has continuity; if the meter display shows no significant change, the switch has no continuity and is faulty. 3 For three-terminal switches, touch the black lead to the “common” terminal and the red lead to the “normally closed” terminal. The multimeter display should show zero Ohms of resistance. Move the red lead to the “normally open” terminal and the multimeter should indicate continuity only after the switch has been actuated. 4 Be aware, if either a two-terminal or three-terminal door switch tests positive for continuity when it should not, it is likely the switch has shorted closed.
What can be tested with a multimeter?
All of these parts can be tested with a multimeter to confirm continuity – a continuous electrical path present in the component: Before you begin testing, unplug the microwave oven power cord.
