Danby Microwave not working

If your Danby microwave is not working, first check whether the outlet has power by plugging in another appliance, then check the home circuit breaker or fuse. If the outlet works, the most likely cause is a blown line fuse, which can prevent the microwave from starting. A damaged or misaligned switch holder may also keep the door switches from actuating when the door closes. Less commonly, the main control board may have failed, but test the more common parts first. An overheated or open thermostat, or a blown thermal fuse, can also cut power to the microwave. These checks may require removing the outer cabinet. The high-voltage capacitor can store a lethal charge even after the microwave is unplugged, so it must be properly discharged before any interior work. Replacing the line fuse, thermal fuse, or main control board should be handled by a qualified technician if you are not familiar with capacitor discharge procedures. Enter your Danby microwave's model number to find the exact replacement line fuse, switch holder, thermostat, thermal fuse, or control board for your specific appliance.

01 - Danby Microwave Line Fuse

If too much current passes through the microwave circuitry, the line fuse will blow. If the line fuse blows, the microwave won’t start. To determine if the line fuse is at fault, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. In addition, you should investigate and resolve the problem that caused the fuse to blow. If you don’t resolve the underlying issue, the new fuse will blow too. (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the potential for electric shock, i...t is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the line fuse.)

02 - Danby Microwave Switch Holder

The microwave switch holder is the component that houses the door switches behind the control panel. If the switch holder is damaged or misaligned, one of more switches may not be actuated when the microwave door is closed, resulting in the microwave not working. You will need to uninstall the control panel and inspect the switch holder to confirm it is in good condition and secured properly. Replace the switch holder with a new one if necessary.

03 - Danby Microwave Main Control Board

The main control board might be defective. However, this is rarely the case. Control boards are often misdiagnosed—check all of the more commonly defective parts. If you have determined that all of the other components are working properly,replace the main control board. (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the main control board.)

04 - Danby Microwave Thermostat

If the microwave overheats, the thermostat trips to cut off voltage to the microwave. If the thermostat is shorted open, it may not allow voltage to reach the high voltage components. To determine if the thermostat is at fault, use a multimeter to test it for electrical continuity. If the thermostat does not have continuity, and it cannot be reset, replace it.

Highly Likely

05 - Incoming Power Problem

The electrical outlet may not be getting power. To determine if the outlet is getting power, try plugging something else into the outlet. If the outlet is not getting power, check the home circuit breakers or fuses.
Highly Likely

06 - Danby Microwave Thermal Fuse

The thermal fuse cuts off power to the microwave if the microwave overheats. To determine if the thermal fuse has blown, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. The thermal fuse cannot be reset—if the fuse is blown, it must be replaced. (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the thermal fuse.)
