This guide explains all Maytag Microwave error codes (CH series) with simple troubleshooting steps to help you identify and fix common issues safely before calling a technician.
Frequently Asked Questions
What are common error codes in Maytag microwaves?
Maytag microwaves display error codes to indicate issues such as keypad failures, door switch problems, overheating, sensor malfunctions, inverter faults, or control board communication errors. Most issues can often be resolved by resetting the unit, checking door closure, ensuring proper ventilation, and inspecting wiring connections.
What does F1 error mean on a Maytag microwave?
F1 indicates a touchpad or keypad shorted condition. Clean the control panel, remove moisture or grease buildup, inspect ribbon cable connections, and replace the keypad if the issue persists.
What does SE error mean on a Maytag microwave?
SE refers to a keypad communication error. Check ribbon cable connections, inspect for stuck buttons, reset power to the microwave, and replace the control panel if communication fails.
What does F2 error mean on a Maytag microwave?
F2 indicates oven cavity overheating. Allow the microwave to cool completely, check ventilation openings, inspect thermal sensors, and replace the thermal cutoff if necessary.
What does F3 error mean on a Maytag microwave?
F3 indicates a humidity or moisture sensor failure. Inspect wiring connections, clean the microwave cavity, check sensor pins, and replace the humidity sensor if faulty.
What does F4 error mean on a Maytag microwave?
F4 refers to a door switch fault. Ensure the door is fully closed, inspect the latch and switch mechanism, check wiring, and replace the door switch if needed.
What does F5 error mean on a Maytag microwave?
F5 indicates a magnetron failure. Unplug the microwave immediately, inspect high-voltage components (technician only), and replace the magnetron or related components if necessary.
What does F6 error mean on a Maytag microwave?
F6 indicates a relay control failure. Reset power, inspect relay contacts on the control board, check wiring to the magnetron circuit, and replace the control board if required.
What does F7 error mean on a Maytag microwave?
F7 indicates an inverter overload error. Turn off the microwave, inspect inverter connections, check magnetron load, and replace the inverter if the issue persists.
What does F8 error mean on a Maytag microwave?
F8 indicates low voltage supply. Check household power stability, avoid extension cords, reset the circuit breaker, and test the microwave on a different outlet.
What does F9 error mean on a Maytag microwave?
F9 indicates a high-voltage transformer fault. Disconnect power immediately, inspect transformer, capacitor, and diode (technician only), and replace faulty components if needed.
Why is my Maytag microwave not heating?
This may be caused by a faulty magnetron, inverter failure, door switch issue, or high-voltage component failure. Check door closure first, then inspect internal components or call a technician.
Why does my Maytag microwave keep shutting off?
This can be caused by overheating, poor ventilation, faulty door switches, or power supply instability. Ensure proper airflow and check internal safety switches.
Can I reset a Maytag microwave error code?
Yes. Turn off the microwave, unplug it for 5–10 minutes, then restore power and restart. This can clear temporary electronic or sensor glitches.
Why do Maytag microwave error codes keep coming back?
Recurring error codes usually indicate deeper hardware issues such as failing sensors, damaged wiring, inverter faults, or control board failure requiring professional diagnosis.
Important: If Maytag microwave error codes continue after troubleshooting, disconnect power immediately and stop using the appliance. Persistent faults may indicate serious high-voltage, sensor, or control board issues. Continued use may lead to electrical hazards, overheating, or component damage. Contact an authorized Maytag technician for proper inspection and repair.
