SOURCE: We own a GE Microwave jvm1653sh01

The first thing I would check would be the magnetron TCO (thermal cut-out). This is a little safety devise that protects the magnetron in the event of overheating. These can act up even without overheating. I believe the nuetral side of this TCO runs through the board, and therefore the flickering and shutdown. When the TCO cools, it resets. If it were the door switch, you would blow the fuse and wouldn't be able to set the time without changing the fuse. There are other cavity thermostats that could be the culprit but my quess is on the magnetron TCO. When working with microwaves always unplug the unit and discharge the capacitor. This is high voltage..Good Luck

If you're getting power at the outlet, the most common problems causing a "dead" condition are a bad thermostat (or thermal cutout / thermal fuse) on or near the magnetron, a blown internal fuse, or a problerm on the control circuit board1.gif.

SOURCE: microwave runs but does not heat

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

The diode is a fairly cheap fix, and the mag will cost more.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

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.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

http://www.gallawa.com/microtech/diode.html (if it's not shorted, it's probably okay)

SOURCE: GE less than 2 year old microwave runs, doesn't heat

The problem you are having is that the magnetron that actually does the heating has gone bad. The fact that everthing works fine rules out any type of bad fuse since there is only one 15amp ceramic fuse in most cases in the unit itself. The magnetron is located behind the control panel on top and has some cooling fins on it. Replacing it if you are a do-it-yourselfer is pretty easy provided you can find one at local electronic supplier or on the internet such as www.mwoparts.com if you would like to see what it looks like. It is held in place with typically 4 screws. It has two to three terminals depending on make and model and age. With everything unplugged it comes off easily enough with no desoldering or soldering to do. There is a High Voltage Capacitor and Diode that could be bad also, but without being able to check it in person it would be difficult for me to tell that they are. In my experience the magnetron is the first thing I replace and have never replaced a capacitor or high voltage diode in the past 20 years. Good luck and God bless.

GE spacemaker microwave turns off during cooking and display goes black


Step 1:


Door Switch




If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently

Step 2:

Main Control Board




If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.


Touchpad and Control Panel




If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.

Touchpad




If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.

High Voltage Transformer




If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.

Thermostat




If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostat

Thing worked fine and then recently started on this inccessant clock reset thing?


Well the only way to fix it, replace the keypad control board, but consider the cost in parts, it will rival some new microwave ovens.

Ge eterna series - installed above oven. microwave stops working and display instructs to set time and date, then after setting time and date and starting oven again it stops after a few seconds and asks...


The magnetron draws a lot of power and the mains may be dipping beneath an acceptable level, causing the panel to reset.
Check the supply cable size and any connections.

Microwave starts and runs 2 seconds and stops. Display is jibberish. After resetting date and time, it will again run 2 seconds and then shuts down again.

Shorting out


Sounds like the units main elecrtonic control board. You can contact your local parts house for the parts as they should have them or call GE at the #b in the owners manual. I must advise you that there is a very hi voltage inside these microwaves so you must have some know how on working on large appliace and if not PLEASE seek a pro to assit you in this repair. Good Luck
