Question about GE Advantium 120 Convection/Microwave Oven

JVM1540DM1WW exhaust fan comes on at random times for no reason

The cooktop exhaust fan works fine manualy- high/low/on/off but the darn thing comes on in the middle of the night and any other time it feels inclined and you can not turn it off. Not only that, but the button control is off in the sense that when the fan is on high the read out says low and vice versa. Once you unplug it you can plug it back in and it will stay off for an hour or so but then will start up again all on its own

I would suspect that your hood fan thermostat is intermittently shorting, or less possibly a relay on the control board is sticking.

The hood fan thermostat (hood TCO) detects excess heat from the stove top and will turn the fan on automatically at its preset temperature.

The one on your model should turn on at 133F and turn back off when the temperature falls below 104F and it should have pink wires attached. (Other models may have different colors).

A failure of either the TCO or relay can cause unwanted operation of the fan.

One way to isolate a bad TCO is to disconnect and tape off the wires on one side. Preferably the side that goes to the fan.

If you or a friend does this, be sure the wire is taped over and secure so its metal will not touch anything inside (including the chassis) and so that the wire will not be damaged.

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.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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

You can unplug the oven, swing the control panel down, find and pull the pink wire on the hood TCO that goes to the fan, tape its connector over and tape the wire to another wire clear of any metal or moving parts.

There's probably no need to disconnect any other wires to get to the TCO wires..

Then reinstall the control panel, plug the oven in, and use it for a couple of days.

If the fan does not come on at unwanted times, then you know the TCO is bad and can order one.

If the fan still comes on at unwanted times, then you have a problem on the control board,

Could be a lot of things but most probably a shorted high voltage diode assembly. If not that then the magaetron or capactors. Remember be careful there are high voltages even when the oven is unpluged. The capactors are usually charged and must be discharged. If you don't know what yor doing then time to get a qualfied tech.

Good luck

My ge xl1800 has 50 volts at the fan when the fan switch is off. it hums because of the low voltage. it works fine when the fan switch is turned on. the fan cap checks out fine


If you have had trouble with the cooktop lights recently, or if you get a hum or buzz in the area of the control panel assembly when you open the door, either indicates that you need circuit board repair. More details here.

My Kenmore Elite electric stove top will turn on fine, but it will randomly cut off. Then none of the burners will heat up, but lights are on like all is fine. If I turn off the power for 5 minutes it...


If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

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

An overheating magnetron can be :
  • operating oven without cover(s) in place
  • wrong magnetron installed in oven
  • an old or otherwise failing magnetron
  • cracked magnetron magnet
  • improper power line voltage (US homes should be 110-125VAC)
  • foods low in moisture (popcorn & bacon, e.g. - add 1/2 cup of water in rear oven)
  • failed or inoperable cooling fan or hood vent exhaust fan
  • deteriorating foam weatherstripping seals in air ducts or on outside cover
  • blocked air vents (dust, animal nest debris, insufficient free air space behind & around oven, etc.)
  • clogged or greasy charcoal filter or grease filter
  • blocked duct in hood vent exhaust
I suspect a failure or the fan, clogged filter or bad magnetron.

Sear's microwave falling apart


If this is and Over the Range micro, the exhaust fan needs to run ANYTIME the cooktop is on. They make things for quantity and not quality, so the plastic has little tolerance for heat. Running the fan, diminishes heat off the front of the unit. Also, the micro MUST be at leat 24" off the cooktop.

Mircowave works, exhaust door opens, fan stop working


From looking at the owner's manual, it looks like the vent fan is only supposed to come on when the internal temperature of the microwave gets too high OR when you press the VENT FAN pad. Here are a couple of fan-related excerpts from the owner's manual, which can be found here: http://products.geappliances.com/ProdContent/Dispatcher?REQUEST=SKUOBJECTS&DOCUMENT=Use%20and%20Care%20Manual&SKU=JVM1840BD (or the better URL here: http://tinyurl.com/yn7r6g) Automatic Fan An automatic fan feature protects the microwave from too much heat rising from the cooktop below it. It automatically turns on if it senses too much heat. If you have turned the fan on, you may find that you cannot turn it off. The fan will automatically turn off when the internal parts are cool. It may stay on for 30 minutes or more after the cooktop and microwave controls are turned off. - Vent Fan The vent fan removes steam and other vapors from surface cooking. Press VENT FAN once for high fan speed, twice for medium fan speed, a third time for low faw speed, or a fourth time to turn the fan off. Press the VENT FAN BOOST pad for extra fan speed. - Hope this helps.
