Common Symptom

Touchpad / keypad fault
Medium
The microwave does not respond correctly to button presses, starts unexpectedly, or cycles through functions without any user input.
View

The unit abruptly halts a cooking cycle before the timer finishes. Attempting to start a new cycle results in F2 displaying immediately.
View

The microwave refuses to begin any cooking cycle that relies on sensor input, such as "Sensor Cook" or "Auto Reheat," displaying F3 instead.
View

Magnetron thermal cutoff tripped
High
The turntable rotates and the interior light is on, but food placed inside remains cold because the magnetron is not producing microwave energy.
View

Door switch / latch fault
High
The microwave door fails to snap firmly into the closed position, or can be jiggled noticeably without triggering a latch, indicating worn or broken latch hooks.
View
F6
Touchpad / membrane switch failure
Medium
Microwave does not respond normally to touchpad input — some keys are unresponsive, produce wrong functions, or register without being pressed.
