Question about GE Spacemaker JVM1640SJ Microwave Oven

1 Answer

Runs whenever door is shut, displays "8 lo code", can't cancel

Out of the blue, our very old Spacemaker II (circa 1986) started running by itself. The display reads "8 lo code", and the keypad is inoperable. When the door is shut, the light is on and it sounds like it is running (fan), but it is not actually working (nothing is heated). Model number is JEM31E001. I know it is very old, but has worked fine to this point. Just curious what is going on. We are not the original owners, so do not have the manual to troubleshoot.
Thanks!

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

GE Over range microwave model JVM1443LK01 This started a couple days ago. After removeing something from the microwave and we shut the door, the fan started up. The fan will run as long as the door is...


I would check the door switches for a faulty switch. If it were condensation on the control panel. I would think it would have dried out by now unless it has damaged the control board.

Hi .. your problem is most likeliy inside the microwave itself. I would replace it. Or you can take it to a shop that does repairs to get a diagnoses and estimate .. but replacement might be the less costly.
