Safely Removing a Microwave Oven's Control Panel

[Ruah57]

I have a 25 m. old GE Spacemaker Microwave over, Model #: HVM 1540 DN 1 WW, under cabinet model. At first it would just stop working, I'd clear and restart, no problem. Then the fan started running every time I opened the door. Christmas morning nothing worked, the digital display was blank. This all happened within 4 days. What should I check first? Thank you.

@Ruah57 There are two versions of this model, so I would need to get a little more information from you. I'd be glad to help you, but technical inquiries are better handled via e-mail. Please send your post (above) to me at prototech@usa.net.

ok I have a amana radarange MVH22OE. it's place on top of the oven.how Do i remove it. and where are the fuse?

thanks

@ulujm To access the fuse, which on this model is in a fuse holder near the door switches, you may not have to remove the oven from the wall.

Once you remove the control panel, look near the middle door switch for the fuse holder.

Another component which can render the oven dead is the cavity thermostat (T.C.O.) located on the top of the cooking cavity / chassis. It has black wires attached.

(cont'd)

@ulujm To access this device for testing and possible replacement you will have to remove the oven from the wall and remove the outer cover.

The installation instructions can be found here: kitchenaid . ca/assets/pdfs/literature/C893­5506.PDF

Also, the thermostat (T.C.O.) on the magnetron may be open, which will make the oven dead. It has black wires attached.

@ulujm Do not confuse these with the hood T.C.O., which has thinner red and black wires connected. If it were bad, the vent fan would just be on all the time.

There is a technical sheet hidden behind either the controls or thew grille, and it is very handy in helping you trouble shoot.

If the fuse, cavity TCO, and magnetron TCO are good, then you may have an issue with the control circuit board, which can usually be repaired economically.

@MicrowaveDisplaycom

ok thanks. I found the fuse on the top of the control panel behind the grid.

Before I started to remove screw on the side of this model and I hear something falling inside not sure what it was. any clue?

thanks

[MicrowaveDisplaycom]

@ulujm It may have been a piece of a threaded post on the grille, which can crack due to heat, aging, inferior materials, etc.

@MicrowaveDisplaycom

ok I put the new fuse and the power came back. but as soon I start microwaving, it just stop after 1s. it looks like the real reason is not the fuse. not sure what is the prfoblem

[MicrowaveDisplaycom]

@ulujm A blown fuse is usually not a cause, but an effect.

When the fuse blows a second or so after pressing "Start", then you probably have a shorted high voltage capacitor.

(if it's not shorted or burned, it's probably okay)

Very good.

Always a good idea to clean a surface well before taping or gluing it.

Glad it helped you!

[iluvlou56]

Thank you SO much! I did not have to watch the entire video to get the answer I needed. I found out how to get to the control panel within the first 58 seconds.

What happened to my microwave, was, the tab that holds the left bottom corner down had broken off. My husband got to the control panel, tipped it forward, cleaned the area with alcohol, and applied some double sided auto trim molding tape, and it is as good as new...I just had to give it a good cleaning! Thanks again!

Yes, you can use a soft cloth (not a paper towel, which will scratch) with mild detergent (not ammonia) but do not damage the plastic covering or the metal mesh.

is it safe to clean the microwave doors from the inside like the metal holes
