Microwave Not Heating

If your Frigidaire FFMV1645TS microwave is not heating properly, there are a few potential causes and troubleshooting steps you can follow:

1. Check the power supply: Ensure that the microwave is properly plugged into a functioning power outlet. If the outlet is controlled by a switch, make sure it is turned on.
2. Inspect the door latch: The microwave will not operate if the door is not securely closed or if the door latch is faulty. Check if the door is closing properly and if the latch is not damaged or misaligned. Clean the latch and the surrounding area to ensure there are no obstructions preventing it from functioning correctly.
3. Reset the microwave: Sometimes, a simple reset can fix minor issues. Unplug the microwave from the power source for a few minutes and then plug it back in. This can help reset the internal components and resolve any temporary glitches.
4. Check the high voltage diode, capacitor, and magnetron: These components are responsible for generating the heat in the microwave. If any of them are faulty or defective, the microwave may not heat properly. It is recommended to contact a professional technician to inspect and replace these components if necessary.

Microwave Buttons Not Responding

If the buttons on your Frigidaire FFMV1645TS microwave are not responding or working intermittently, try the following troubleshooting steps:

2. Reset the microwave: Similar to the previous issue, a reset may help resolve button responsiveness problems. Unplug the microwave from the power source for a few minutes and then plug it back in.
