GE Microwave Troubleshooting & How to Guide

GE Microwave Troubleshooting & How to Guide

Owning a GE microwave is convenient since it allows you to enjoy all the benefits that come with high-grade microwaves. They are designed to fit in any modern kitchen seamlessly. However, like all other electric appliances, even the best products experience hitches once in a while. It is essential to understand how to deal with such issues when they arise. This article explores the most common problems with the GE microwave and guides users to diagnose and fix them where possible.

How do you reset a GE microwave?

There may be instances when you need to reset the microwave for it to serve you better. Proceed as follows:

  • Start by pressing the “Off/Clear’ button. This cancels anything on display and automatically resets the microwave.
  • Pressing the “Off/Clear’ button for about three seconds will help turn the “Control Locked” child lock off.
  • Consider resetting the cooking program if the “Off/Clear” was accidentally pressed when in progress.
  • Consider a hard reset that simply pulls the plug from the power supply and waits a while before plugging it back. The microwave’s memory will rest any anomalies from before.
  • Reset the time of day by clicking the clock button and turning the dial to set the exact hours.

Why does my GE microwave trip the circuit breaker?

There is a possibility of an overload on the electrical circuit. This means that the course has a lower rate than what the microwave requires. It keeps exceeding the electrical unit current of the circuit.  To fix it:

  • Plug the unit into an alternate outlet. Consider areas with higher amperage, such as your garage or workshop
  • Alternatively, connect it to a dedicated circuit
  • If the problem persists, then the microwave is the problem, and there is a need to have a technician look at it with possible repairs in mind. You should also be open to replacing it.

It happens when there is an issue with the magnetron. This is a component in the microwave that is part of the high voltage circuit. It is responsible for the gadget’s heating capacity. When defective, the issue may be a blown fuse, especially if their functions usually work. To fix it, consider replacing the fuse. However, watch out for the following signs first s they signify a problematic magnetron.

  • Failed heating.
  • Strange burning odor.
  • Snapping and arcing sounds.

How to tell if your GE microwave fuse is blown

Before replacing or changing any fuse, you first need to check and confirm that it is blown. Do this by:

  • Removing the grill
  • Search for one screw on top of the control panel.
  • You will notice the control panel top tilting out.
  • The fuse block will be visible.
  • Look for more than one fuse as they are at least 2 or 3
  • A blown fuse should have scorched marks, and the filament is going to be melted
  • Use a continuity tester or ohmmeter when the fuse is ceramic
  • The readings should show zero if the fuse is okay and an infinite figure if it is blown

GE microwave error codes: meaning and fixes

Understanding the potential errors helps you quick-fix your microwave. Standard error codes with the GE microwave include:

  • Code F1: Indicates open thermal sensor resulting from excessive heat when the microwave is in action
  • Code F2: Problem of a shorted thermal sensor
  • Code F3: Issue with shorted touchpad panel
  • Code F4: Problem with an opened immunity sensor
  • Code F5: Issue with shorted immunity sensor
  • Code F6: Issue with shorted temperature probe
  • Code F10: Problem with shorted touch screen
  • Code Probe: Issue with an open temperature probe or the probe is unplugged during the temperature cook function. Always ensure that the probe is fixed firmly into the microwave’s wall.
  • Code 888, 8888, or PF: May occur during initial installation or after a power outage. It simply means that there was a power issue. Fix it by canceling the display and proceeding with normal operations, which happens when you clear the pad. You can also reset the clock.
  • Code 18/ power watch code: Shows an issue with the electronic control

It is possible for the touchpads on the microwave to stop responding despite the display lights working as expected. Unplug the microwave to access the membrane switch and remove the cabinet altogether.

GE Spacemaker microwave troubleshooting

It is possible to troubleshoot and rectify some of the common problems that your GE Spacemaker microwave has. To do this:

  • Replace the charcoal filter. This works especially if the microwave model is not vented outwards and there are excessive smoke and odors when venting.
  • Disconnect from power and remove the old filters behind the grille.
  • Open the grille and slide out the old filters, replacing them with new filters before replacing the grille.
  • Always close the door if the microwave fails to start. Check the plug to see if it’s fully inserted in the wall socket.
  • Correct the time of day if there is an unusual low-tone beep. You could attempt to start the reminder with no valid day or that you tried to start the auto night light without a valid on and off time.
  • In case of a sensor error, wait until the steam is sensed and the timing completes before attempting to open the door. Alternatively, heat the microwave longer by using the time cook option.

Several things could be wrong with your microwave. It is up to you to notice the issue and address it accordingly. Common issues are:

  • Door Switch Issues. When your microwave has door switch issues, then it is likely not to start. In most cases, the door switches are primary and secondary interlock switches, and they power various components of the microwave when it’s closed. Always check these switches for continuity.
  • The ceramic fuse may be the issue when the microwave fails to turn on. This should b your first suspect, especially if the display is blank. The ceramic fuse protects the microwave’s internal components from fluctuating power supply. When it fails, the power supply is cut, and it should be replaced.
  • The thermal fuse may be the reason why the microwave fails to start. The problem may be a thermal cut-out whose role is to protect the microwave from overheating.
  • The door latch assembly can also prevent the microwave from coming on. The two hooks on this contact latch should power the controls to keep the door closed.

What do you do when your microwave shuts down every time you switch it on?

  • Find out what is blowing a fuse, especially if it keeps recurring even after several replacement attempts
  • Narrow your search down by first identifying if the issue is on a high or low voltage side
  • Find the relay o the board feeding the transformer voltage by tracing the wires and looking at the wiring diagram
  • Unplug the wire, then plug it back in after replacing the new fuse
  • If it doesn’t trip, then the issue was on the high voltage side
  • Remove all wires and from the capacitor after disconnecting the microwave. Using the ohmmeter, check for continuity across the capacitor. It is likely to be the culprit, and you will confirm this if it has a continuous current reading.
  • If doing this still does not fix the tripping issue, you may have to do the same thing for the low voltage side and remove components on this side, such as the fan and turntable motor. However, more often than not, the capacitor is always the challenge you need to deal with.
