The turntable on my GE spacesaver xl 1800 stopped turning. The model number is JVM1850BH01 I would appreciate any help.


On this model, the power to the turntable motor ("drive motor") is supplied by a tap (outlet terminal) on the internal cooling fan motor.

The other side of the turntable motor's power is switched on and off by a relay on the control circuit board.

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

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

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.

If the cooling fan is running, but the turntable is not, then it's probably a relay issue or connection which we can repair.

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 an GE Eterna Microwave Model Number: EMO3000HWW01 The microwave resets itself after aboout 10 seconds of use. Before it would do this and we would reset the time and date and it would work for...


It may be that the internal cooling fan is not working or the filters or air duct may be clogged, but it may also be a "noisy" magnetron.

First, check the filters. Then determine if the internal cooling fan is coming on.

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.

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

If that is working, and you have good air flow, then see this FixYa solution.

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

My ge microwave quit working while i was cooking in it. it is if a breaker blew but none did. i plugged it into another outlet and still no power. does this microwave have a fuse or reset button? it is...


The parts I would suspect are (in order) the TCO (aka thermal cutout / thermostat) located on the magnetron, the TCO on the top of the oven cavity, the bottom TCO (not to be confused with the hood TCO, which should read open), or the 20A ceramic line fuse, which is likely to be located on a filter board near where the cord comes into the unit.

Accessing some components (especially the oven cavity thermostat) for testing and possible replacement will require you to remove the oven from the wall and take off the outer 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.

You can download GE owner's manuals and installation instructions here.

Kenmore Microwave blows internal fuse


Is the fuse holder tight?

You shouldn't be able to easily rotate the fuse with a thumb and finger while it's in the holder.

If it's loose, that can cause a fuse to overheat and melt inside.

Is the internal cooling fan running?

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

The high voltage transformer may be failing.

This is usually accompanied by an electrical smell, but it may be slight enough that the cooling fan disperses it.

You can temporarily disconnect the fan and run it for about a minute (no longer - the magnetron will overheat) and then see if you can detect smoke or smell.

Be sure the loose connector is taped off so it doesn't contact any connections or get hit by a fan, etc.

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.

You can find exploded views and order parts by entering your model number at the Sears parts site.

But Sears parts can usually be obtained for far less here by entering either the part or model number.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

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.

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.

Acer Computer Turns Off


Hey ArtWest,

One of the most common reasons why this might occur is if your computer is overheating due to poor circulation or blocked ventilation. As such, I'd first suggest giving the computer a thorough cleaning using an air duster, and making sure that the external vents are not plugged. If there's any kind of obstruction blocking these vents, the internal temperature of your computer can rise to the point that it must shut itself down to prevent any kind of damage. Remember to always hold these dusters at least six to eight inches away from the surface(s) being cleaned, as they have been known to leave liquid residues behind or freeze surfaces when held too close.

Additionally, overheating may be caused by the failure of an active heat sink (fan). If you feel confident in opening your computer's case, you may wish to verify that all of the fans are working correctly when the computer is in operation. Many computers will have at least two internal fans: one to cool the CPU, and one to cool the case itself. Some models may have several extra fans to cool the video card or to help improve circulation.

Assuming that cleaning the computer does not resolve the problem and all of your internal fans are still operational, you could potentially be looking at a more serious problem: a possible defective processor or motherboard.

Remember though that any repairs not performed by a factory-authorized technician may void your warranty coverage, so make sure to contact Acer first if your warranty is still in effect.

Hope this helps you out.

Sincerely,
Aaron
Go Ahead. Use Us.
