Microwave has not got a hub for turntable

buy one of the wind up ones that last time I looked were still available on places like EBAY.

It might considering the cost of a new unit be cheaper and better to measure it and replace it?

I have a Maytag mmv4205baw Microwave oven. It

the unit that creates the microwaves called the "magnetron" has gone bad, or the circuits powering the magnetron have gone bad. there really isnt a cheap way to fix it, and not a undangerous way to fix it yourself. if your really like the microwave and dont want to part with it, you can try finding a repair shop that will fix microwaves, but they will probably tell you it would be cheaper to buy a new one. sorry

THeood is not getting heated and the turntable is

the unit inside the microwave that heats called the "magnetron" has gone bad or the circuits that power the magnetron and turntable have failed. if its under warranty still, send it back to the manufacturer. if not you can call some repair shops and see how much it would be to service it, but its most likely going to be cheaper to purchace a new microwave since they are relatively cheap these days, and electronics repair people are not cheap. hope this helps

I'm asking about a problem my parents have with their Sharp Carousel microwave. When using the oven, it stops after about a minute, then when the door is opened, the turntable starts revolving and the fan...

If this is a countertop microwave and is not an expensive unit, it will not be cost effective to pay someone to repair it. Best thing is to just buy a new microwave especially if it is very old. The cost of the repairs could easily be more than a new unit and sometimes you pay to have it repaired an then something else goes wrong. With the condition you describe I would not use this unit until it is repaired or replaced with a new one.

Delonghi EM821AAN-800watt The turn table has stopped spinning

Make sure the turntable guide is lined up properly and there is no debris caught in it. Examine the turn table bushing the tray sits on and make sure it is not worn or broken. Make sure the turntable is sitting down in the groove correctly. Lastly it may be the drive motor itself is bad. This is the small motor that turns the carousel. This motor is very difficult to replace and unless you are qualified you should not attempt this repair and leave it to a professional. This motor will cost from $40 to $75 plus the cost of having it replaced. You may want to consider buying a new microwave if this unit is over 5 years old. You could end up spending more to repair this one than a new one costs. Of course you can use it without the carousel.

LG Countertop Microwave why stopped rotating?

Microwave turntables are belt driven from a small motor.

Usually it is the belt that needs replacement.

Unplug, and remove the outer case to inspect the belt. If it is still tight and attatched, the chances are it needs a new motor - often it's cheaper to buy a new unit.

The turntable in the microwave does not rotate.

First you need to see if it is the motor that is bad. Usually you find the relay or switch that powers the motor and see if you have voltage.
Microwaves are better left to professionals. A novice could hurt themselves working on a microwave. I would suggest getting a repair man to fix it or buy a new microwave (whichever works out cheaper for you)
