Where is the fuse on a Frigidaire GLMV169D

You blew the fuse on the control board. Unplug it, remove the cover to expose the guts, and you should see a fuse. Replace it and try again. If it blows again, then you will likely find it cheaper to get a new microwave than have the control board replaced.

You need a microwave fuse. Also the reason for it blowing fuses may be that it's time to replace the capacitor inside. It may be time for a new magnetron too. If you have the top open look to wires that burned in two and may be touching the frame If that is so you may not need any parts at all. Also check the thermal cutoffs (button looking safety equipment)

If it's not that old, it might be under warranty. There is a host of conditions that can cause an oven not to heat, from a simple corroded terminal to the magnetron.

the magnetron. is what heats

The simplies is the fuse, which is located inside the unit, you need a screwdriver to open it

High voltage parts are suspect. Need to put a voltmeter on the input (primary) side to the high-voltage transformer (big heavy iron thing in there) Should be getting 120Vac when it goes to cook cycle. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing either the magnatron or the high-voltage capacitor and diode. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!
