Does it heat? If so, then The problem is likely on the control panel, which we repair nationwide for $39.95 postpaid.

The light failure often occurs when a bulb goes out and the filament shorts, causing a failure on the controller.

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

Turntable is not turning and we do not have a manual Model is JVM1660BB005 GE Profile


The turntable on many of these models get their power from the internal cooling fan.

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the turntable and stirrer won't work, and magnetron will soon be destroyed.

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

I have a GE SpacesaverXL model JVM1350BW. It does not heat up. The interior light, surface light, fan, clock, keypad all work normally. When a cooking mode is chosen and START is pressed there is a...


I wouldn't worry about the sensor error right away.

Sometimes that's just caused when the door is opened before steam could be detected or steam was not detected in the maximum amount of time.

Once it's all working again, if you still get the error regularly, it may be a bad humidity sensor.

If the internal cooling fan IS running when you try to cook AND the oven is not heating, it's probably a failed secondary interlock relay on the control circuit board.

If the internal cooling fan is NOT running when you try to cook AND it's not heating, the bottom door switch is probably the culprit.

Here's is a file on checking and replacing door switches.

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are working.

Listen to that very carefully, and listen to yours to see if the cooling fan is working.

No lights or fan


If you mean that when you press Start and try to cook, the inside light and internal cooling fan are not working and it is not running, you may have trouble with a door switch or door switch mount. See this file.

Accessing some parts may require you to pull the oven from the wall and remove the cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

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, cooling fan, turntable, and/or inside light operation, too.

My DSpacemaker JVM 1640BJ fan doesn't work


I would wonder if you've had trouble recently with the cooktop lights?

Such failure can cause damage to the control board (which we repair) which can cause either fan to act improperly.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

Also I would wonder if it's the internal cooling fan or the hood vent exhaust fan?

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the turntable and stirrer won't work, and magnetron will soon be destroyed.

Many brands have 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.

Tappan microwave TMV151F will lose power during operation. I think around 3 or 4 minutes.


The magnetron is overheating and causing the magnetron thermostat to open.

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

This is usually caused when the internal cooling fan is not running or by a magnetron that is failing.

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the magnetron will be
destroyed.


It may also be a clogged exhaust duct or filter. Grease filters should be cleaned regularly and charcoal filters should be replaced (not cleaned) every 6-12 months.

You can refer to your owner;s manual for that info.

You can download most Maytag / Whirlpool / Tappan owner's manuals and installation instructions here.

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.
