My xl1800 spacesaver microwave makes a loud squeaky sound when it's running. When I stop it I can hear the spinning slowing down and the sound goes away until I restart it. I'm afraid that it may blow up. Is there anything that I can do to fix this?

Is this an over the stove type unit? I have had a few problems with my over the range spacesaver. I think the heat from cooking gets up into the microwave and damages it. The steam from me boiling things on the stove had mine quit heating and I purchased a new one. The parts to replace the faulty ones can be quite expensive over $150.00, so its better to purchase a new microwave.

ITS MAY BE HIGH VOLTAGE SIDE PROBLEM. DIODE OR CAPACITOR

Hi


Thanks for using FixYa. If it’s a loud hum/buzz sound then 90% it’s usually a bad magnetron and other times it’s a bad high voltage diode. However, from what you have described it seems to be the magnetron. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

you say it has aloud hum to it? And everything works but no heat.Im going to give you a list of things it could be and you'll have to take microwave apart to do the work. Beforre you start get some small trays or pill bottles to put screws in. Make sure when you take a screw out you know where it goes back because all the screws may not be same length. First, You may have a blown fuse in the HV transformer primary circuit, The HV transformer is the largest thing you'll see when you take the cabinet of the frame.Second,bad connections for the magnetron filament the magnetron will have what looks like fins or louvers around it.look for bad wire connections. Third, could be a faulty thermal protector or fuse, More than likely its either going to be the HV transformer or the magnetron thats bad.

if the microwave still heats then the turn table motor will need to be replaced.. very easy repair

It sounds like you could have one or two problems. Using the oven with metal in it could cause the magnatron to go bad at its tip causing it to arc and making a popping sound. It could be that there is bare metal exposed somewhere causing the popping sound. Take it in for service!!

The second problem is probably defective door switches, or it may be a problem with the control panel, which we repair nationwide for only $32.50. On my Web site, I have info on safety, disassembly, and diagnosing and replacing door switches: http://tinyurl.com/yzjozk Running it empty has damaged the magnetron. It will work for a while, but it will eventually have to be replaced. A good parts source is here: http://tinyurl.com/gv383
