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.

@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.

Help links - read safety warnings first:

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

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 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 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

@ulujm If this was not clear, e-mail me with your full model and symptoms.

@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.

@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.
