Question about GE Microwave Ovens

1 Answer

Was cooking in microwave and it totally shut off. Light went out and stopped. After a while "PF" appeared on the panel. What caused this to stop and what do I do to get it back working? My model is either JES1036 or JES1136

    I appreciate the information. I was able to program the clock and used it the next day. Seems to be running alright now as I have used the defrost and regular setting.

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.

First of all, be sure the internal cooling fan is running. That's critical to protect the magnetron by keeping it cool.

You can test this by running the microwave with a cup of water inside. First, cook for about 2 minutes on the lowest power setting and see if it makes it to the end. Then cook on high for 2 minutes and see if it makes it to the end.

If the defrost test works, but the full power test does not, then the magnetron is overheating.

If you or someone you know wants to look into this, we have critical safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa.

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

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.

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

It sounds like instead of an overheated magnetron thermostat tripping the power, you now have a defective door switch.

Our door switch help file is 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.

Totally dead,,,quit while cooking....checked fuses, none blown...no lights on control panel...outside got quite hot


In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

During cooking, the microwave will work for about 3 minutes then completely shut down.There appears to be a complete power failure.After the units sits for about 5 minutes,it resets itself and you can cook...


sounds like the cooling fan has came adrift or stopped working , this will cause the magnatron ( the microwave generator ) to overheat tripping the over temperature stat ,so fix the cooling , but be sooooooooooooo carefull in there , microwaves + really high voltages , not really a job for a non electrician/microwave tech

GE XL1800 Micro fan won't shut off after light burned out


The problem appears, at least in part, to the door latch circuitry which cannot be serviced by the owner. If the unit is still in warranty, call GE customer care. If not, replacing the unit is your best bet. I just bought a new GE 1100 watt oven with great features for less than $100 If the door dosen't latch correctly, you could be exposed to dangerous microwave energy.

Does Not Shut-Off Completely


This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There may also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

Door switches are most often damaged by opening the door while it's cooking (instead of pressing Stop / Clear first) or food
/ grease debris in the switch.
