There will be a switch that the door presses when it closes, somewhere around the edge of the entrance to the microwave, double check this is clean and able to move freely.

Microwave power off, but will flicker when door shuts


Please inspect the plastic latches that should actuate the door switches. Sounds like you may have broken one when slamming the door too hard

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

Jenn air microwave JMV 916 BAS won't power up


The magnetron has probably shorted, and in rare cases the power transformer will fail, "but unlikely"

Frigidaire microwave not heating over the range


Hello

Try to cook something simple such as microwave popcorn. If the unit does not light up or turn on, check the outlet with another appliance to make sure the outlet is functioning correctly.


Check the fuses or circuit breakers in you house. If the outlet does not work after testing it with another appliance, try to plug the microwave in a different outlet.


Check the hinges and door hooks to make sure the door is closing properly. Look to see whether a small piece of food is clinging to the door, preventing it from closing all the way. Check the release mechanism and the rotating plate to make sure they can move freely as well.


Plug in the microwave and start it a the bag of microwave popcorn inside. If the lights go on but it is not producing heat, listen and try to hear whether the unit sounds the way it usually does. If it does not, there might be problems with the circuit board. This will need to be repaired by a certified Frigidaire professional.


Check the display that shows the time and power. If the display is flickering but it does not alter the operation of the microwave, it is not a problem. If, however, the lights flicker and your food is not heating, there may be a problem in the microwave cabinet.


Listen for buzzing sounds. If there is a buzzing sound and no heat is being produced, you may have to get a new magnetron, power diode, or high-voltage capacitor. These can be purchased from a Frigidaire retailer.


Look at the handle on the door. The most common complaint about all models of the Frigidaire microwave, according to Consumeraffairs.com, was cracked or broken door handles. Frigidaire will replace faulty handles while the oven is under warranty. In many cases, they will replace the handle even after the warranty expires for a "reasonable" amount of time.

1800 XL JVM1860BD - won't work


It sounds like your controller may be failing. Or it could be an electrical line problem. Any other electrical itmes giving you trouble? Has anyone measured the voltage level of your power line? It should be around 110-125 volts AC. If it's significantly lower or higher, you may have a bad connection in your breaker panel or in the wiring leading to the home.

My Microwave flickers and buzzes


This problem normaly happens when the door is not closed properly for a long time and flashing and buzzing starts to give user a indication for same. Allthough it is not risky as microwave oven has safty door switches wich does not allow oven to operate while door is open. Take care and close the door properly before you leave kitchen..

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
