Depending on the model of your Frigidaire microwave, the fuses are typically on located behind the control console, on the magnetron or on the oven capacity. However, if your microwave does not heat, you may possibly have a faulty control panel, magnetron, or experiencing an issue with the power supply. Please confirm that your microwave is plug into its own outlet and that you are not using a GFI outlet. Hope this helps! - Z

If you are talking about no power, the fuse is open. But you have power the problem is one of three things, magnetron, cracked high voltage diode, and a shorted high voltage capacitor.
If not, contact Electrolux at the phone number on the front of the service manual.
It may be the C/T fuse (thermal fuse located above the magnetron) or the oven cavity thermal cutout, located on the top of the cavity.
Accessing these two parts for testing and possible replacement will require you to remove the oven from the wall.
If
so, the installation instructions are very handy, and it's best to have
two people since the microwave can be heavy and awkward. You can
download Electrolux / Frigidaire owner's manuals and installation
instructions here.
It may also be that there was a power surge which damaged the control circuit board, activating the built-in surge protection.
This is not resettable. The circuit board has to be repaired. We do that for $39.95, details here. We're

Unplug microwave, remove the top cover "several screws" fuse location under keypad and near the high voltage capacitor "silver and rectangle in shape" fuse is a ceramic type, must be replaced with identical fuse and rating, and don't forget to discharge capacitor with "long handle screwdriver"
If everything is ok, the fuse of microwave oven is located inside the unit, if you have a screwdriver, unplug the power cord and open it, you'll find the fuse
This problem is almost certainly caused by the thermistor failing. The thermistor is located at the air outlet of the unit. This is a thermal resistor that cuts off the electricity to the unit if it overheats. Sometimes it can fail from age.
Go to; http://www.appliancepartspros.com/
and enter your unit number. You can even get diagrams in the left-hand corner screen.
Replace with same value thermistor. Also see if a mini manual in hidden behind the control panel.
Where is fuse located
