Dead GE Spacemaker

I bought a new GE Spacemaker (with exhaust fan) about 2 and a half years ago.  i've had no problems until yesterday when it suddenly died.  No display characters, nada.  i can see a tiny yellow (non LED) light behind the display, but no buttons will respond.  The door seems to latch OK.  I unplugged and replugged, leaving it off for like an hour in between.  Still nothing.  I checked that outlet and it works just fine with another appliance.

From what I gather, it is most likely the fuse???  However, the same sites that indicate that, say no homeowner should ever, ever, ever try to replace the fuse.  I'm not even sure that's what it is, but if there's any way I can buy the $5 fuse and swap it out to see before pulling the whole thing out and paying hundreds for repair/replacement, I'm all for it.

Suggestions?

    Thank you so very much- that's great info and I'm very happy to have the links.  The fuse didn't fix it.  It was working one minute, the next we went to put something in it and noticed it was dead in the water.  Hasn't done a thing since, except that tiny light behind the keypad (no green letters, just a tiny bulb back there).  I think the rest of that stuff may be over my head.  But THANK YOU!

    my spacemaker xl1800 is doing the same thing. it acts "sluggish" buts still heats. if i try to use it for more than 4/5 minutes, it just cuts off and will eventually come back on. i remodeled my kitchen about 27 months ago and chose ge for the reputation and style. i guess i made a mistake. is this something i can possibly fix or do i need a new one? this one cost over $500 and my kitchen cabinets are custom to fit this microwave.

A microwave can be dead for many reasons.

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

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

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

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

I'm all for fixing appliances but in your case I would suggest replacement. After 24 years of service the magnetron is probably only putting out half of its rated wattage. It could also be one of the reasons of the no heat condition.

Touch control failed on GE Spacemaker Microwave HVM1540


If you want to order a touch pad, (it has the micro computer built in it!) and fix it that way, you'll still have a 2-3 year old machine.
I would say it would be quicker and cheaper to buy a new one.

GE JVM1640 won't heat


These microwave ovens have a series of door switches. One of yours has gone bad or a plastic finger on your door mechanism that pushes the switches is worn or broken off. They are commonly called NC or NO swithes some ovens have up to 6 of these working together.If you have no expertise in this field consult a repair shop. Please rate me
Comment posted on Jan 12, 2009 there are two types ,normally open and normally closed, NO NC . u have to check continuity on each one and each switch will have a diagram on the side showing its in use position. I hope this has been helpful

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.

It sounds like two separate problems.

1. It sounds like your magnetron is overheating and then the thermostat trips, cutting the power until it turns off, then it closes to power it back up.

It's essential that the internal cooling fan (I don't mean the hood / vent / exhaust fan) is running to be sure the magnetron stays cool.

2. It also sounds like your vent / hood / exhaust thermostat is sticking or the triac on the circuit board is leaky, causing the vent fan to stay on.

But you may want to check the owner's manual. It is designed to stay on if the temperature of the stove top is above a certain level.

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.

2 year old ge profile spacemaker Microwave lost all power


Inside unit is a cylinder fuse which can blow for a number of reasons. External cover needs to be removed to access. If you are confident in doing this and can find & check the fuse then it would be my first guess. If fuse is OK then you will need to have repaired. If fuse isblown & you replace then it blows again,you will need to have repaired. regards
