GE Profile Over the Range microwave - Model PVM9005FM1DS

Unit is just over 1 year old and cooks fine.

However, interior light and fan run constantly. This is the interior fan, not the vent/exhaust fan.
Unplugging / hard reset does not help.

When the door is opened, the light will stay on but the fan will turn off.

Any ideas on a fix?

Unplug the machine. Open the door and access the latch assembly and interlock switches on the right. (the two hooks on the door go into the latch assembly) On your model it might be easier to pull it out and remove the cover. The problem is one of the interlock switches. Check the switches for continuity one at a time. Remove the wires and check by opening and closing the door.

Thanks for the help Rick - once again you guys have come through with expert advice.

Update on this issue:
I opened the panel and located the two latch switches. I disconnected the top switch, plugged the microwave back in, and the problem stopped.
So, the top switch was the problem.

The good part is that when I reconnected the switch, the microwave still operated fine. So, apparently, just disconnecting-reconnecting the switch reset the latch and took care of the problem.

So, at least for now, everything is working fine, and if it happens again, I will know where to look.

Thanks a lot!

Next time you open it up, spray a little WD40 on the switch buttons then open and close the door a few times (unplug machine). Sometimes the switches get sticky. It will probably go out again. Glad you got it working! Thanks for the update.

I had the same problem and disconnecting, reconnecting the door switches also fixed it. Thank you

Hello - I had the same thing happen on my 1yr old microwave today. I am not savvy at removing the latch is there a diagram or picture that can point to disassembly please?

Check YouTube. Take the cover off and it looks similar to this:

Thank you

Anytime!

This worked for me. For those who have this model. To remove the panel - with door open - first must remove the plastic cover over the filter (two screws), gently pull vented cover toward you and off. Then remove two top and two bottom screws on panel right side facing.
Gently push panel up (sliding). It is held in by hooks… then you can remove the panel.

The switch will be easily seen just inside and adjacent to where the latch connects. Disconnect the wires harness and press in the tiny yellow or white buttons (actuary switch).

This depressing of the switch apparently fixes the problem (most likely due to grease goop that causes it to stick.) put the latch harness back on - temporarily put the panel back in place and retest.

It worked -

Not really, it's just a temporarily fix. It will stick again.

I have a GE Model PVM9005EJ3ES microwave oven. I replaced all 3 door switches and the interior fan keeps running.
That leads me to conclude that a thermostat has gone out, but which one. The Interior Parts diagram shows 3 of them:
One by the magnetron cooling fan and two by the magnetron.

Thanks in advance.

Rick has been out sick since Jan.12th with a serious illness, we are hoping and praying for a speedy recovery!

So unfortunately you'll have to wait for him to return or hopefully another tech. like @jeff1 or @Dan O. or another member that's run across this problem, can help you here.

I replaced all 3 door switches and the interior fan keeps running.

How about the interior light and turntable?

According to the unit's wiring diagram (tech sheet # 31-41093) they're all connected together. If they're all operating and the switch is not the problem, there is no "thermostat" I see that could be responsible. They are all powered directly from the main control board which would then likely need to be replaced to correct the condition.

I don’t know Rick, but I pray for his speedy recovery.

@Dan O., Thanks for your reply. The turn table works but I believe the light burned out at some point. I’ll recheck the switches and positioning of the switch bracket.

 

[Dan O.]

The turn table works

I was asking if they operate together, at that same time as opposed to only the fan running that you mentioned.

All the switches work correctly.
I removed the burned out light bulb and reseated all the connections the controller board a couple of times, and it works correctly now. Thanks.

 

[Jake]

Sounds good.

Thanks for the update!

Thanks Dan for assisting him too!
