Question about Microwave Ovens

Exploding microwave sounds - No Lights, No Fan, but Heats Okay

My wife put something in it 3 days ago and started to turn on the fan and light, when POP!!! (and the appropriate circuit breaker tripping did occur on its 20-amp, dedicated circuit). When it happened it something seemed to explode on the microwave's underside. It still heats just fine, but has no fan or lights working underneath anymore. Any ideas how this might happen and what to do? I wondered about grease buildup and a shorting out on an internal circuit board or something.
Okay experts give it your best shot! ALL IDEAS APPRECIATED!!

Ken with no Light (and no Fans).

We see this a lot. The problem is on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

I have a JVM1850 that was installed 4 years ago. The unit was working fine, then a day ago I received an error display requesting a charcoal filet replacement. No filter is needed since it is vented...


I have a JVM1850 White microwave-over the oven-installed 3 years ago. Last evening the unit would not turn off. The inside light and fan continued to run, however, the microwave was not working.

All the controls and functions seem to operate, but when completed, the unit remained working, as stated above, with the door opened or closed.

sounds like a cross wire, and a short. I'd inspect the socket for the bulbs to ensure that there's no short circuit.

Microwave makes a loud roaring sound when start is pressed to cook something. The turntable turns and lights go on, but sound is horendous. We quickly stop it fearing it might be melting down.


Most likely it is the magnatron has gone bad, this or the fan for the magnatron. If your handy you can dissasemble the unit and look for a damaged fan, if none found then the magnatron is most likely bad.

Micreowave does not heat items. Turntable, fan, and interior lights all work. Sound while running changes after about 3-5 seconds.


The magnetron has more than likely failed, "heats food" but also! the high voltage capacitor and diode can be a source of trouble, chances are repairs will exceed the cost of a new microwave oven.

Kenmore 665.6061200 over range microwave. Problem started a few days ago with a clicking sound from the RH side of the unit (seemingly behind the control panel), about 3 clicks per second for about 3-4...


The most likely cause of the clicking sound is the power relay that is connected to the microwaves PCB (circuit board) that turns the magnetron on and off. If starting to fail it may result in multiple clicks, then once fully failed, your microwave would simply not heat anything (as the high voltage components would not be getting power).
Unless you have a strength in electronics and repair, and understand the lethal dangers involved in working on a microwave, even one that is unplugged, this problem will likely need to be repaired by a qualified service centre.
Depending on the microwave design and the technician the whole relay circuit board may need to be replaced making this repair vary from relatively inexpensive to more expensive.

Microwave popped and now does not heat


Okay, first we need to separate the situations. You were boiling water on the stove and had the range hood fan running to **** up the steam. Then you put something in the microwave to heat and you heard a pop and then zip-o.

The water on the stove has nothing to do with the situation, the fan you turn on is not part of the microwave, so it has nothing to do with the microwave.

The pop you heard and then the humming suggests the magnetron failed. You said you found a blow fuse and replaced it and still nothing, right? The magnetron is the most likely culprit...I would think it is safe to say that the magnetron shorted and drew enough current to blow the fuse.

Replace the magnetron and if that doesn't work, let me know here. Good Luck!

I'm guessing that nothing is working...is that right? If so, first guess is the breaker or an internal fuse. Nearly all units have them. You don't say what fuse you checked. Unplug the unit, remove the bulb and see what is in the socket. Next, open the breaker and then turn it back on. This will reset it. Something caused this.

Microwave Buzzing, Still Heats, but Turntable And Fan Not Working


This is not safe. If the fan is not running, the magnetron will quickly overheat and be destroyed. We answered this in more depth in the other place you asked it.
