Microwave oven won't work

My Microwave lost all power at once. When it happened, there was water boiling on the stove beneath, and the automatic fan on the microwave was blowing at the time. I checked the outlet, and it works fine.

Re: Microwave oven won't work

If the internal fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven or veen on the floor of the oven chassis.

Hopefully the vent fan was on strong enough to keep the steam out the of controls. That steam could scramble or damage the circuit board or keypad.

You should unplug it from the power line for a few minutes, plug it back in, then try again.

Fan comes on by itself and won't turn off.

Is it a micro hood? If so, and you're cooking on the stove below, it may be that the microwave is getting too warm. Some of them have an automatic fan the comes on when you're cooking below them - especially when boiling potatoes or something else steamy.

Fan comes on automatically

Actually, that's a feature! If you cook much on the range (stove) beneath the microwave, the heat will cause the microwave bottom to heat up quite a bit (just touch it!), and the microwave will turn on it's exhaust fan in an attempt to save itself from burning up. It will shut off in about 15 minutes after you turn off the source of heat.

Micro won't work after boiling water under it all day

I am not sure what you mean by boiling water under it all day. If it was under the unit, it probably shorted it out and it won't work. If you were using it constantly to boil water, you may have overheated it. To be safe, please unplug it and call the manufacturer.

The LCD display is not showing the numbers correctly. It looks like the numbers are missing "lines", like an 8 can look like a 3, the 8 can look like a 0, etc. Any ideas?

It is the control board that needs to be replaced. The LCD display is connected to the board. If this is an above the stove microwave the problem was caused by the steam from boiling water on the stove top. you can prevent it from happening again by using the vent fan consistantly.

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!

GE Microwave Profile Spacemaker Runs on its own

Your microwave turning on by itself is a "self preservation feature" of the GE Profile Advantium and maybe some other models. Read the manual, When your over the range oven gets warm enough, for whatever reason the venting fan comes on until a satisfactory oven temperature is reached. You are not permitted to shut the vent fan off. Also it seems a temperature near room temp must be achieved before it shuts the fan motor off, it is very annoying. We had to return our Advantium because of fan noise. I configured the ovens vent fan to the recirculate direction because we do not have a vent duct that exits the house over our range. When the vent fan acting as the ovens cooling fan automatically turned on we would have to leave the house to hear each other talk. Too bad we really liked the oven other than that major problem.

I have an over the stove kitchenaid microwave w exhaust hood. About 1/2 hour after boiling water on my stove, my microwave comes on. I have unplugged the microwave-----any ideas?

The issue is probably your exhaust fan on your microwave comes on automatically when it detects a certain temperature. Mine does this as well but will turn off automatically after temperature goes down.

Microwave will not work

Hello Carol95,
I would doubt that the heat generated from the cook surface beneath the micro caused any damage to the micro however the fact that you had a power surge is the more likely culpret. It is possible that a power surge took out an internal component, such as the magnetron, thermal fuse, filament transformer or something else but the cost of a repair call may warrant a replacement MW anyway. Why pay for a service call if all you will learn is that your MW was damaged from that surge? and the cost to repair would exceed the cost to replace.. There are virtually no servicable parts inside the micro that the homeowner should attempt to fix.. If you do not know what you are doing, you can get seriously injured or compromise the RF shield in just gaining access to the inner compartment. You might luck out and learn that the failed component is a simple and inexpesive repair ... so you weigh the risks..
Hope that helps you decide how to approach this..
