Question about GE Microwave Ovens

Oven Won't Start

My JVM1860BD001 will not turn on. I have power to the panel, lights, and fan. I checked the secondary door switches and they both close when the door closes. The fuse is good. I have read that the turntable motor can cause this problem but I have a relative with a similar model and a bad motor and the oven works fine. Thanks!

You need to use an ohm meter on the switches to verify that they are actually opening or closing electrically. You could also have a bad thermal protector. Check for one on/near the magnetron to make sure it has continuity. And, there are many other less likely causes, as well. Too many to list.

SOURCE: Fan runs when door is closed - no heat

This is normally 1 of the interlock door micro-switches not working.

SOURCE: Fan runs when door is closed, but no heat.

It's probably a bad door switch or switch mount. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk Feel free to contact me directly if you have further questions. I appreciate your thoughtful rating of my reply.

SOURCE: Sharp Combination Oven R-953M -

If the turntable runs when you try to cook with the microwave portion, then the problem is either a bad relay on the control board (RY2, primary interlock relay) or something wrong in the high voltage section.

If a high voltage problem, it may be as simple as a loose connection on the magnetron terminal or a bad high voltage rectifier diode or as costly as a high voltage transformer or magnetron.

Most of the time the magnetron will have a 5-9 year warranty, and you would only have to pay labor charges to have it fixed. If you take it to the shop yourself, you can save quite a bit.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Samsung smh8165b won't power


The fuse is probably open, when this happens it usually indicates a secondary problem from a defective door switch, keypad control board failure to a inverter board issue.

The 13amp fuse blew in the socket and when replaced the light and fan worked in the oven however no heat was produced...any help would be greatly recived the oven is a newhomes el616.


Door switches

If one of the door interlock switches is not switching properly or there is a condensation problem on the sensor control panel, either can cause the turntable/light/oven to come on even though the "Start" button has not been depressed due to the wiring of the switches or it can take the mains power fuse out and stay faulty.
Check for faulty door switches and/or contaminated actuators.

Alternatively, the magnetron, supply or HV diodes can fail and take the mains fuse out.
I hope that helps.

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.

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.

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.

Re. Viking DMOS200 1100 watts microwave oven does not turn on


I'm guessing that's a VMOS200?

If so, that's a rebranded Sharp R-530ES (as is the Dacor DMO2420S) and its secondary interlock (bottom door switch) or that switch's mount is bad.

See this file on door switches. If you only need a switch, you can order a universal type here for $5 postpaid.

The Sharp R-530E service manual will aid you in disassembly and it is here.

GE 1800 XL not heating, no power, except fan works and clock also


Hello :

It could be bad door switch or loose door switch mount . 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.

or it could be problem with the control panel .


good luck .

please rate !

My Dacor DMT2420 fan, light and turtable motor run continuously when the door is open. I have unplugged the unit to reset it with no help, another on-line forum expert suggested checking the door switches...


If the cooling fan, light and turntable run continuously when the door is open, but not when it is closed, your secondary interlock (bottom door switch) is shorted (always on).

Even if it's shorted, the actuator button (usually red) will still move up and down when you open and close the door.

It will need a new door switch.

See the service manual here. See our file on door switches here.
