Question about Frigidaire FMV156DC Microwave Oven
Everything on the microwave seems to be working fine except it will not heat on any function.
SOURCE: Where is the fuse?
It won't be the fuse. If the fuse were out, it would be completely dead.
Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part

This is just a preliminary reply. We will need more information to help you.
So you're saying you can set the cooking time but when you press Start it won't start?
If this is the case, you probably have a bad door swithc or door switch mount.
Please reply back with more detail so we can help you.

It has a bad magnetron. This is the tube that provides the microwaves to heat the food. Not too easy to replace yourself but it can be done. Cost of magnetron is probably less than $50 or $60.

Hi,It is most likely the magnetron and diode that has to be replaced. This job should be done by a tech, High voltage. Magnetron's normally have a five year warranty, check your owners manual.
