Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.

You either have a bad magnetron tube or a shorted high voltage rectifier. Seek professional repair.

    Check the thermal cutoffs for both the oven and the magnetron. The thermal cutoffs are little disc shaped devices with a wire connecting the two of them. Remove a lead and set the VOM to RX1. Probe the terminals and look for a reading of zero. If not, replace. Check both thermal cutoffs. If these are OK, check the capacitor and diode as described above. The magnetron or transformer could also be bad, but they need to be serviced by a professional.

    Check the voltage at the outlet supplying power. If it is lower than 115 volts, there is a problem with your electrical service or breaker. A bad turntable motor may also be the cause. To check it, turn the microwave over onto its top. Remove the bottom grill. Set the VOM to RX1 and remove one lead from the motor terminals. Probe the terminals. If the reading is infinity, then replace the motor.

    Test the capacitor by removing the leads and setting the VOM to RX100. Probe the terminals. The reading should start in the low ohms and increase toward infinity. Reverse the probes and re-test. The reading should do the same thing. If not, it's bad. To test the diode, disconnect the diode from both the appliance and the capacitor. With the VOM set to RX100, probe the wires. Then reverse the probes and read again. You should get infinity for one reading and low ohms for the other reading. If not, replace

    The U. S. Consumer Product Safety Commission

    (CPSC) warns against do-it-yourself repairs of

    microwave ovens. Each year, on average, four

    people die from electrocution trying to repair their

    microwave ovens. Microwave ovens use high

    voltage which makes it particularly hazardous for

    consumers to remove the cover and touch electrical

    parts. The possibility for electrical shock

    from a microwave oven still exists even after the

    oven is disconnected from the power source.

    Should certain internal devices fail, even

    unplugged ovens can cause serious injury.

    Removing the cover of your microwave oven

    and touching an electrical part can kill you.

    Have a professional repair your microwave oven.

    I cannot offer advice on this topic as I am not licensed. You have a serious electrical failure with your product. My advice is to seek professional "licensed" assistance.

It makes a sound when on and smells like burning


If it's an arcing sound, there may be grease or food particles on or behind the waveguide cover or in the area of the turntable motor.

Otherwise, it's likely to be a failing high voltage part:

- A sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound. Usually it will not heat is this is the case.

- A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but if this were the case, it would not heat.

- Sometimes a high voltage transformer will cause a loud hum and burning smell, too.

GE Spacemaker XL1800 does not heat. All other functions appear to be working normally, the light comes on and the turntable functions. When turned on, it makes a humming noise slightly louder than normal,...


Possible bad heating element, You should remove the cover of the unit and look at the heating element with the power off. Until you get your problem resolved I would recommend not to even turn it on due to the fact that you are unsure what is going on and you smelt some burnt smell. Just for safety until you fine the problem

GE JVM1440BD Won't Heat


If it making a louder than normal humming or grunting sound when operating, than it's a sure bet it's the MAG.

Humming sound and burning smell.


I had the same problem. I replaced the wave guide/cover and everything was fine. It is a piece of cardboard inside the microwave that covers the magnetron. Mine was saturated with grease, and was damaged by the fire. If yours is still intact and not that greasy, You can carefully remove it. Clean both it and the area inside the cavity with an alcohol based cleaner. If there is so much as a pin hole in the cover it will need to be replace. When grease somehow gets behind the cover an arc is formed which causes the problem.
