E-Wave Microwave not working

If your E-Wave microwave is not working, start with the line fuse, which can blow when excessive current passes through the microwave circuitry. Test the fuse for continuity with a multimeter, but do not replace it without addressing the problem that caused it to fail. A damaged or misaligned switch holder is another likely cause because it may prevent the door switches from actuating when the door closes. If those parts check out, the main control board could be defective, although it is rarely the cause and should be considered only after testing more common components. An overheated or failed thermostat can also stop voltage from reaching the high-voltage components. Next, verify that the outlet has power and check your household circuit breaker or fuse. Finally, test the thermal fuse, which shuts the microwave down during an overheat condition and must be replaced if it has no continuity. Any repair that requires opening the outer cabinet involves a high-voltage capacitor that can store a lethal charge even after unplugging. Proper capacitor discharge is required, and a qualified technician should handle this work if you are not familiar with the procedure. Enter your model number to find the exact replacement part for your E-Wave microwave.

01 - E-Wave 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 - E-Wave 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 - E-Wave 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 - E-Wave 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 - E-Wave 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.)
