Question about Whirlpool MH2155XPS Microwave Oven

1 Answer

What does the fuse look like?

I see a black 1/2"X2"X1.5" unit which is screwed to the side panel behind the control panel. It has two wires attached. I also see a round black knob below that which has two wires attached. Between these is a caution decal saying to use only a 20AMP fuse. Are one of these the fuse that might blow if the light over the range is shorted? I don't have a wiring diagram of fuse description. Please let me know what the fuse looks like and where it is located.

Panosonic Microwave convection Model NN-8501V Touchpad appears dead

The unit has a fuse in the power board, but when the fuse is gone it does not even start up. If it starts it is not the fuse.

Look rather a problem with a faulty touchpad, or the magnetron that is not working and need to be changed.

Check also the door sensor.

You will need to remove the top grill vent first, then you can remove the screws coming in from the top of the grille vent then that will expose a screw holding down the control panel at the top. Remove the screw and remove the control panel. The fuse is located in a little 1" fuse holder just behind the front panel near the top.

1 the obvious question.... have you tried a known working outlet. 2. Most likely the internal fuse has failed and must be replaced. You can access this fuse by removing 4 side panel screws, (2 on each side) and 6 rear chassis cover screws. BEFORE you start unplug the unit. Remove the 10 screws. Standing behind the unit, then lift the top cover slightly and pull toward you. the side guide tabs wil unlock and the cover will come free. Once the chassis open aviod the large capacitor as it can still ruin your day. Follow the power cord until you see the fuse block. Remove the fuse... obtain an EQUAL value replacement and install the new fuse. reinstall the cover making sure the side guide tabs interlock on the front sides of the chassis. Plug the unit in and see if you have any signs of power.... I.e light on with door open or control panel dispaly lights up. If you have visible signs of power places a coffee cup filled with water inside the microwave and see it it heats up. If it starts and then all the power goes off again you probably have a bad diode. If it works fine then your in luck.

You know that you have to unplug the microwave first, right?Then you have to either wait a good while (I like a couple of days) or short out the current.

The fuse is located on the right side, behind the control panel at the top. You have to remove the vent cover (three screws) in the front, then the screws holding the control panel up ( I didn't remove mine, I let it rest on a pot to take the weight off the connectors). The fuse is on a small horizonal electronic board located 6 inches behind where the top of the control panel normally is attached.

You do NOT have to remove the oven, but it's small hands work, or great needle nose. You get the fuses for about 3 for $2.00 at Radio Shack.

But I bet that isn't you whole problem. Something caused it to blow.

My microwave turned off with no display and i have made sure all the breakers are on.... what else could be the problem? GE profile XL1800

It may be the internal 20A fuse or a thermal cutout (TCO) on top of the oven cavity or mostly likely the one attached to the magnetron.

These models do not use a "screw-on" type fuse (whatever that is - a "guru" after 46 votes?!), it will be a 6x30mm ceramic type and it simply snaps into the fuse holder.

Being a GE, there should 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 locating components and troubleshooting, and testing.


At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Since you mention Profile XL1800, that means the all-important model number from the tag in or on the unit would probably be something like JVM1861WB001, etc.

Using the actual model number, you can find helpful exploded view diagrams and order parts here.

Accessing some parts may require you to pull the oven from the wall and remove the cover.

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.

How do I open the front panel of GE Spacemaker 2.0 ? Fuse?

there are screws either on top of or in the grille that allow you to remove it. after screws are removed, open the door, pull lightly toward you starting at the control side if it does not pull, then it may have to be pushed toward the hinge side, then pulled out. behind the grille, is the screw attaching the control panel. lift the panel up before pulling out. Just to add a thought,if the display lights up it is probably not the fuse, although, in some models there is a high voltage fuse, it is pretty rare.

Change Fuse Whirlpool Gold GH7155XHS1

no the control does not come off from behind.

what you will find is the top vent grill has to come off first. it has 2 phillips screws that hold it to the top of your unit.
you will find 4 screws on the top, go ahead and take all 4 out and then pull the grill out from the top and hinge outward to remove/ once the grill is off, then there is 1 more phillips screw that holds the control board/ touch panel to the frame. remove and then lift up then out on the panel.
now that you are into the unit, make sure you have UNPLUGGED it first. the fuse is about 1 1/4 inch long white ceramic material with metal ends. you can find a new one at a radio shack or get one online for your unit. r/s has them for cheap and if that allows the unit to run again, great, but...
there was something that caused the fuse to go bad. so dont be surprised if you need a diode or capacitor to fix why the fuse went bad.
