Turntable drive may be fouling on cabinet.
Take out the table and see if it is still slow. To centre the drive- take the panel off the bottom, you may have to cut the metal the first time

SOURCE: Microwave quit

I would suspect either door switches or an intermittent control circuit board, either of which can be repaired. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure over time. I have a text file on my site called "doorsw.txt" which helps in diagnosing and repairing door switch problems. You can find the file via a Google search. It will help you check and replace the door switches if you or an able friend is so inclined. In some cases, the problem is a bad connection or a bad relay on the control board. That's something we see fairly often, and we repair them for only $32.50 nationwide.

SOURCE: Over the range Goldstar microwave not working????

(If you need more help than this, please reply back with your model number)

It's probably a bad door switch or door switch mount.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

If you only need a switch, you can order one from us for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

It could have been steam or humidity.

If this is an over the range model, be sure you always use the hood vent exhaust fan when you're cooking on the stove top.

Whether it's a counter top or over the range top, always be aware that the cooling fan is running when it's cooking.

When in doubt feel for air flow through the vents.

Good luck.

SOURCE: Microwave Oven Does Not Start Cooking

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

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.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.

If yours is not shown at the parts site or manual site linked above, Please reply back with your brand and model number so we can help you.

If you only need a switch, you can order a universal type here for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.

GE Microwave (JVM1860CD001) control board buzzes.

see this causes and fix it. God bless you
Magnetron If the microwave is loud or noisy only when cooking, the magnetron tube might be defective. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. Under normal circumstances the magnetron is nearly silent. However if it is damaged or nearly burned out it can begin emitting high pitched or growling noises. It's not normally dangerous to use a microwave oven when it makes these noises, but they are an indication that the magnetron is almost dead and will need to be replaced.
Exhaust Fan Motor If the microwave is loud when running the fan motor might be
Stirrer Motor If the microwave is loud or noisy the stirrer motor might be worn out. The stirrer is a metal blade which slowly turns around, deflecting the microwave energy in a random pattern inside the microwave oven. As the motor nears the end of its useful life it begins to make grinding noises. The microwave will not heat food evenly without this stirrer, the motor should be replaced.
Turntable Motor If the microwave is loud or noisy the turntable motor might be worn out. This is a common problem and relatively easy to replace.

Frigidaire microwave doesn't work

Don't have a fix for your problem, but my Frigidaire microhood just did the exact same thing--about the same age, started cooking some food and it worked for a few minutes and then just stopped--time kept going, light stayed on, but turn table stopped and fan noise cut out. I tried it a few more times and it seemed to fade in and out and then stopped trying.

Turns on by itself and turntable does not rotate

You may have a control board issue. Thank God for safety switches.
This is a problem that an integrated circuit tech. can repair, but it may be costly.
Decide how much you want to put into this oven vs. buying a new one.

Contact me once you decide and I can help you find a service center.

Thank you,

I don't have the manual but there should be a temperature setting for the fan to come on.
