How come my over the range microwave does not turn on at all??


Check internal fuse. If it's ok, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. Diagnostics and repair might be quite complicates so better you take it to a repair service. You have some interesting Youtube video tutorials to repair a microwave

It all depends which fuse is it the plug fuse as used in the UK or the internal fuse? If it the internal fuse either the magnatron has gone S/C or the high voltage rectifiers have gone S/C and will need replacing the the indentical components

GE Spacemaker microwave makes groaning sound when start button is pressed for a second or two then blows the internal fuse. After replacing the fuse everything seemed to work, lights, exhaust fan, cl


Could be a lot of things but most probably a shorted high voltage diode assembly. If not that then the magaetron or capactors. Remember be careful there are high voltages even when the oven is unpluged. The capactors are usually charged and must be discharged. If you don't know what yor doing then time to get a qualfied tech.

Good luck

How do I reset the internal fuse in my Kenmore model number 721, which was produced in July of 1995? email: patrick.hegarty@synergyoperating.com


Typically, the internal fuse is not resetable ... hense they call it a fuse ... not a circuit breaker.

Remove the cabinet and find the fuse on the floor of the oven near where the cord enters the cabinet. Check with a contunity checker.

Don't touch anything that looks dangerous ... like the big silver capacitor.

Dead Microwave - Internal Fuse?


After replacing the internal fuse (see other posts to see how I did it) the microwave is working fine (so far). We have used it 5 or 6 times without any issues.

It may be the internal fuse, or the thermal fuse / thermostat / thermal cutout on the magnetron. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
