SOURCE: microwave stopped working

Generally, you get something unless the fuse inside is blown. There is generally a fuse inside the unit when you remove the button package. First, make sure that the outlet you have is good. Plug something else into it and see that it works.

SOURCE: Sharp Microwave Model R-1830: No power

A microwave can be dead for many reasons.

It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.

If the fuse is good, it may be an open oven thermal cutout (TCO) on the top of the oven cavity / body or an open thermal fuse on or above the magnetron.

These should read closed (virtually zero) on a continuity check.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it went dead or when you plugged it in or opened or closed the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

You can usually find exploded views and order parts by entering your model number here at the Sears parts site but the best place to order Sharp parts is Tritronics.

We have the service manual for this model and have uploaded it to our site here to help you.

A microwave can be dead for many reasons.


It may be the fuse, which is usually located behind the grille, on the floor of the oven behind the control panel, between the door switches, or on the filter board near where the cord comes into the unit.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking TCOs or thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

So don't let that fool you.

If the cavity thermostat needs to be checked or replaced you'll need to pull 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 GE owner's manuals and installation instructions here.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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

Microwave model MMV5207BAW won't power up when pluged in. Outlet has power but microwave wont power up.


Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

Start button doesn't work for all microwave functions--as well as timer--fuse is ok


Possible causes:

1. No power to outlet (overload or fault in microwave or other appliance).
2. Blown main fuse - likely due to other problems.
3. Open thermal protector or thermal fuse.
4. Defective controller or its power supply.
5. Clock needs to be set before other functions will operate (some models).

Microwave won't turn on. Seems like it is not getting power. I checked breaker. I am looking for a fuse. You know where one is? It is a GE Spacemaker(2 yrs old) model # JVM1440WH04


  • Make sure that the microwave is plugged into a grounded outlet. It must be a 3-prong outlet.
  • Make sure the clock is set.
  • Check to see if a programming sequence was entered. Sometimes improper programming or a program sequence such as delay start can cause the touch panel to be non-responsive. Unplug microwave or turn off house circuit breaker for 30 seconds. Plug back in, or reset circuit breaker, and try reprogramming unit.
  • Check the house circuit breaker or fuse box. If the microwave is DEAD and there is no display and nothing works- the problem could be a blown fuse or tripped breaker.

My maytag microwave lost power


There is always a fuse inside a microwave.Sometime this has only blown due to a surge,and upon replacing, the microwave will continue working.If it is something worse the fuse will continue to blow.In this case it could very well be the transformer,but there are other possible causes as well.(for example the control board or a short.)

My Ge SpaceMaker XL1800 Microwave Oven won't power on any more.


1.Check power outlet for working.
2.If it is than you have broken fuse inside the m/w.
3. To change the fuse you have to disconnect the power to m/w, take the upper grill off, take the screw on top of control panel, lift the control panel up and removed. The 20 Am fuse located behind this panel.

Microwave dead


First, there is an outlet. Plug in something else. Inside the key panel, there are fuses and a thermo sensor. Either may be bad. The thermosensor is about the diameter of a dime, black and 3/8 inch thick...attached to the wall of the chamber. All should have continuity.
