Re: Microwave

You can usually find helpful exploded view diagrams and order parts by entering your full model number here:

There should also be a very helpful "mini-manual" hidden inside the unit behind the control panel. It's very helpful when troubleshooting.

If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostats.
If the microwave runs for a few seconds and stops the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.
If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.
If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the dishwasher display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.
If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.
If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.
If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently.

Fuse keeps blowing

If the microwave oven is the newer type [7years or less], the problem is most likely the magnetron or the inverter board, but if model is older check for a shorted high voltage capacitor.

Whirlpool microwave mh1170xs no power

Sometimes you get lucky with just changing the fuse, the most cost effective way to fix a microwave oven.

Does model MH7110XB have a fuse? We have no power and have tried checking the circuit but no luck.

Yes it has a fuse. Take the cover off and the fuse is on the right hand side, behind the control panel

Where is the fuse located on the MH1170XS and how do you get to it?

Fuse is usually located behind the control panel. Most likely 20 amp. If your m/w has a top grille it will have to be removed. Look for a screw in the top of the control panel. Panel has tabs to hold it to body, lift up to release panel. A word of warning... m/w ovens have potentially lethal high voltage present even when the unit is unplugged. If you are not familiar with high voltage circuits, then this is not a job for a DIYer.

Microwave not warming

Hello :

It could be bad door switch or loose door switch mount . There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly .

But If the microwave doesn't work at all , then It could be a problem with the power transformer or the power PCB . Or it could be just a fuse . You need to check first . If it's the fuse , then that will be easy to solve , you need only to replace it with new one . But if the problem is with the transformer or with the PCB , you need to take your microwave to the service for repairing .

CAUTION: A microwave oven is capable of giving you a serious electrical shock, even when it is unplugged. I strongly recommend you seek the assistance of an appliance repair technician when conducting any microwave oven repair .
good luck .

Microwave blew up after cooking an egg

Yes the internal fuse will have blown. I would also think the door latch switches and monitor switch will also need re adjustment
