For a while, the microwave would intermittently work. Then we started getting "Sensor Error" on some modes. The microwave completely stopped heating, although the other features would work. We repl

We have visably inspected the magnatron, and it doesn't have any visible burns, etc.

The magnetron can look perfect but it or the inverter (power board) and a large diode often used usually cause this--all will look ok.....

SOURCE: Microwave works intermittently

This is most commonly due to a failing door switch or door switch mount. But it may also be a bad connection or bad relay on the control board, which we repair nationwide for $39.95. Also, it could be a loose connection at the magnetron. 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 You can find helpful exploded view diagrams for similar models here: http://tinyurl.com/gv383 You can order parts at http://www.wehaveparts.com

SOURCE: intermittant heating

You probably have a new unit by now. The Magnetron part inside usually is the problem with this Maytag unit.I have had this unit blow the 'Magnetron' four times ! Everything else works fine. After watching the technician, I replaced it myself the other 3 times. The whole unit has to come out of the wall to do this. This High Voltage part is dangerous. The part costs about $100.00 from an online parts store. Partselect.com- or someone else.

SOURCE: Sensor Error, Funny Smell and Noise

On GE models, "SENSOR ERROR" appears on the display when:

  • Using the sensor feature, the door was opened before steam could be detected. Do not open the door until stream is sensed and time is shown counting down on the display.
  • Steam was not detected in the maximum amount of time. Use Time Cook to heat for more time.
If none of these conditions apply to your situation, then you may have a defective sensor and/or magnetron.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour. Then let us know if the hard reset does not fix it.

SOURCE: Sharp microwave oven works (lights,

First you need to make sure that all "normally open" door switches are closing when you close the door. Next would be the diode. That is a little black thing that runs from one of the capacitor terminals to the chassis. You should have continuity one way, but NO continuity when you reverse test it. It is like an electrical check valve so to speak. If that shows open both ways, or continuity both ways, replace it and you should have fixed your microwave oven. Of course there are a lot of other ways your oven does not work. Get back to me if you need more help.

The magnetron may be intermittent or the keypad control board is the problem. My recommendation is to use it until it finally fails and go out and buy a new microwave oven, "more cost effective"

The sensor errors are probably just from opening the door and interrupting the sensor cook cycle.

By the way, you should always press "Stop" before opening the door of a running microwave. Otherwise, the door switches will prematurely fail.

I would first check the door switches and their mounts. See this help file.

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

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.

I have a sharp microwave sometimes it works for 10 or 20 seconds and then stops with error ee2, other times it works fine. Today it did the same but stopped with error ee1!


This sounds like a keypad problem, sometimes a short developes in the keypad controller causing all kinds of intermittent problems, on the back is the microprocessor circuit board which controls vital areas of the microwave oven. The cost to repair will be high and consideration should given to looking at a replacement.

GE Spacemaker microwave oven - Sensor error


Hello :

Many models of the GE microwave have sensors that can detect humidity from the foods you are cooking. This allows the microwave to make adjustments to the power levels used to cook your food. If "Sensor Error" appears, you should either press "Clear" to cancel the mode or leave the food in the appliance longer to give the microwave more time to detect the food.

Press "Time Cook" to manually enter the time if you receive an error message when trying to use the "Sensor Reheat" mode of your GE microwave. The error message may be caused by the food item being too large or too small to detect
..


good luck .
