    Mine is pretty much the same, but the microwave deteriorated over a short period of time. It started by clicking, like a relay going on and off but very quickly, when we tried to either microwave or use the light/vent. The clock worked fine during this time, but eventually even the clock went out rendering the unit useless. Any idea on where to start?

    Thanks!

    I have a spacesaver xl1800, it is about 3 years old. It has had no problems at all, then the lights went out. No power to the key pad, no light in the over when the door is open. I did replace the two fuses, (H.V. and Main Fuse) with no change. Of course, i check the outlet to ensure that it is working. Any suggestion on the the step?

A microwave can be dead for many reasons.

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

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 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: http://tinyurl.com/yzjozk

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

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.

I had the unit repaired by an appliance technician. He replaced the board behind the keypad and all is well now.

Blowing main breaker


I have a hard time believing that the home's main breaker is tripping instead of the branch circuit breaker that feeds the microwave. I suspect it is really just a difference in terms. You should disconnect it and try using in another outlet - preferably one on a different circuit if possible. If the breaker continues to trip; this appliance should be disconnected and either be discarded, repaired or replaced before using again.

If the microwave works as expected (on a different circuit), it may indicate the original circuit is overloaded. Microwave overs are supposed to be installed on a dedicated circuit. This means only one outlet is on the circuit - no other loads (lights, appliances, etc.) are permitted on this circuit. A microwave typically requires 10 Amps or more when on "high" and will require a significant portion of the power supplied by a 15 or 20 amp circuit breaker. There is little unused to power much of anything else. If other appliances go out when the microwave trips the circuit breaker, you should contact an electrician to have a dedicated outlet installed for the microwave.

I hope this helps!

We had an power outage and lost power for a few hours everything came back on but the microwave. I checked the outlet and checked the fuse still nothing. Is there anything that can be fixed?


Hello if you have no power at the outlet, you may have saved your microwave. If the outlet is dead go to your house electrical panel and reset the breaker or replace the fuse. if the outlet is live and the microwave still won't power on you will have to choose between repair and replacement. Definitely get an estimate before agreeing to a repair as microwaves are very inexpensive today compared to even a couple of years ago.

Power and lights dim on microwave when it is working


this is a voltage draw from the transformer,
check to ensure the unit is on a dedicated circuit, not shareing an outlet with anything, this could also be a warning sign that your magnetron or transformer is going bad,

Microwave has no power


Is the outlet ok? Can you plug somethng else into the outlet to see if the fuse or breaker controlling the outlet is ok? If there is power at the outlet, unplug the unit and remove the outside cover.
Look for a blown fuse on the motherboard. Replace it with the EXACT value of the original fuse. You can purchase a new fuse at Radio Shack or hardware store or auto parts store. Try powering up the unit again and see if it works now or whether the fuse blows again. If it blows again, the power supply may have been damaged. Was this a power outage or surge? Was anything else in your home affected?

dotsie...you're not telling me if anything else works. Do you get the clock? Do you get power? If it is just the light, it is likely the bulb. If it is everything, start with the outlet...does it have power? If yes, then we can go inside and check around. See some of my other similar comments.

There won't be a reset button.

Is it dead? No display, no lights, etc.?

If your outlet is live but your microwave is dead, then you likely have an open internal fuse, thermostat or thermal cutout.

Please post back if you need more help and think you or a friend want to work on it.

Under Hood Light, bulb is fine (brand new)


This is a problem with the control board, which we commonly repair for $32.50. This is caused by not disconnecting the microwave from the power line when removing or installing a bulb. Feel free to e-mail me at _ for more information or visit _ for full details.
