By following the steps drawn above, you can easily replace the fuse and get your microwave up and running again. Remember to always exercise caution and follow safety procedures when working with electrical appliances.

 

 

How to Change The Capacitor Step-By-Step Procedure

If your GE microwave not working but has power, it could be due to a faulty capacitor. A capacitor stores electrical energy and releases it during the cooking cycle. A defective capacitor can cause the microwave to stop working, and here's a step-by-step guide on how to check and replace a faulty capacitor:

 

 

Turn Off the Power: Before you start, make sure the microwave is unplugged or turned off at the circuit breaker.

 

 

Locate the Capacitor: The capacitor is usually located near the magnetron, which is a large cylindrical metal object. Refer to the user manual to find the capacitor.

 

 

Discharge the Capacitor: Before checking the capacitor, it's important to discharge it to prevent electrical shocks. Use a screwdriver with an insulated handle to touch the metal terminal of the capacitor, and then touch the other end of the screwdriver to a metal surface on the microwave. This will discharge any stored electrical energy.

 

 

Remove the Capacitor: Use a screwdriver or pliers to disconnect the wires attached to the capacitor. Then, remove the mounting screw that holds the capacitor in place and take it out.

 

 

Check the Capacitor: Using a multimeter, set it to capacitance mode and place the probes on the terminals of the capacitor. Check if the reading matches the value specified in the user manual. If the reading is significantly lower or higher, the capacitor is faulty and needs to be replaced.

 

 

Replace the Capacitor: If the capacitor is faulty, replace it with a new one that matches the specifications outlined in the user manual. Insert the new capacitor and secure it in place with the mounting screw. Reconnect the wires to the terminals.

 

 

Reassemble the Microwave: Once you have changed the capacitor, reassemble the microwave and plug it in or turn on the power at the circuit breaker.

 

 

Test the Microwave: Test the microwave by turning it on and checking to see if it's working correctly. If the still microwave not working but has power, you may need to consider other possible causes, such as a faulty door switch or magnetron.

 

 

Replacing a faulty capacitor in your microwave is a simple and cost-effective way to fix the problem of a microwave not working despite having power. However, if you're uncomfortable working with electrical appliances, it's best to seek professional help.

 

 

So, a faulty capacitor can cause the issue of your microwave not working but has power. By following the steps charted above, you can easily check and replace a defective capacitor and get your microwave up and running again. Remember to always exercise caution and follow safety procedures.
