Unplug and cease using this as you are exposing yourself to electro magnetic radiation. The door switch may have failed, you will need to disassemble the front panel to access the switch which is located within one of the holes that he door's hooks insert into and depresses to inform the control board the door is closed and is safe to operate.

If it goes dead or blows the breaker or GFI when you plug it in or open or close the door, then there's a problem with a 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. Other times, 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:.

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

There may 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.

Are you sure it is the internal blower and not the VENT fan ?

SOURCE: G.E. Profile Microwave Model JVM2070SH01 turn table does not turn.

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

SOURCE: GE Advantium 120 Microwave fan stays on, off only when door open

Looking at the schematic in the service manual here, I would say relay RY6 on the small sub PCB (relay board) has shorted contacts.

That's the relay that runs both the fan and turntable.

It's possible that it may be a bad connection or driving component on that board, but in my experience, it's virtually always a stuck relay.

The part number on the relay as shown in the photo is hard to read, but it looks like "OJ-SH-112LM".

I should have one of these or I can point you to one if you want to contact me with the exact number.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

GE profile microwave internal fan continues to run when door is closed . When door is opened it shuts off . This is not the exhaust fan . Overall the microwave still works fine ??

It is a cooling fan used for cooling of magnatron as the temperature of magnatron rises when microwave mode is used, cooling saves this component from any defect.

GE Profile microwave PVM1790 starts, what I believe is an internal fan, when I open the door. I sure hope it's not the microwave component frying me.

You probably have a defective door switch, or a bad relay. You are not being microwaved. It would blow its internal fuse to prevent that from happening.

The fan runs when the door is open just like it does when it's running. When the door is shut and not running the fan is off. I opend/shut the door 3 times firmly like the GE rep. told me to but it still...

Hi.

Disconnect the oven from power and allow cooling down. Most GE have temperature controlled fan system.

The Fan is controlled by main pcb and powered along the line passing through the door lock switch, with circuit supplying power to the magnetron and turntable motor.

The fan is also operated directly by the control board.

If the turntable was also running, then the door switch is shorted. In that case the magnetron may be working as well, better not to start the microwave oven.

If only the fan is running, then the main pcb must be replaced, or the damper motor relay must be replaced.

Call GE and arrange repair, the unit is faulty.

GE Microwave Profile Spacemaker Runs on its own

Your microwave turning on by itself is a "self preservation feature" of the GE Profile Advantium and maybe some other models. Read the manual, When your over the range oven gets warm enough, for whatever reason the venting fan comes on until a satisfactory oven temperature is reached. You are not permitted to shut the vent fan off. Also it seems a temperature near room temp must be achieved before it shuts the fan motor off, it is very annoying. We had to return our Advantium because of fan noise. I configured the ovens vent fan to the recirculate direction because we do not have a vent duct that exits the house over our range. When the vent fan acting as the ovens cooling fan automatically turned on we would have to leave the house to hear each other talk. Too bad we really liked the oven other than that major problem.
