PF
Microwave displays PF (Power Failure) and may beep; clock may reset.
Power Interruption or Line Voltage Issue
SE
Microwave displays SE (or 5E) and beeps; keypad may appear to press itself or be unresponsive.
Shorted Keypad Error
Symptom
Microwave clock loses time or resets intermittently without showing PF; unit otherwise works.
Control Board Power Supply Instability
Symptom
Microwave display is dim, flickering, or completely blank, but the unit may still operate when buttons are pressed.
Display or Control Board Backlight Failure
Symptom
Microwave display works and accepts time, but pressing Start does nothing; no relay click, no light, no fan.
Start Circuit or Door Interlock Fault
Symptom
Microwave door will not open or is very hard to open; latch may feel stuck.
Door Latch Mechanism Jammed or Broken
Symptom
Microwave door will not stay closed or pops open during cooking.
Door Latch or Hinge Misalignment
Symptom
Microwave emits a burning smell, smoke, or arcing (sparks) inside the cavity during cooking.
Arcing or Cavity Damage
Symptom
Microwave has a strong, persistent odor (burnt, chemical, or food smell) even when not in use.
Odor Contamination in Cavity and Vent System
Symptom
Microwave interior light does not come on when the door opens or during cooking, but the unit heats normally.
Cavity Light Failure
Symptom
Microwave intermittently stops heating or shuts off mid-cycle but the display remains on; may restart after cooling.
Thermal Cutout or Overheating Shutdown
Symptom
Microwave keypad buttons do not respond or respond only intermittently; display may still be lit.
Keypad or Control Panel Failure
Symptom
Microwave makes loud buzzing, humming, or grinding noises while running, louder than normal fan noise.
Excessive Noise – Mechanical or High-Voltage Component
Symptom
Microwave runs (light and turntable on, fan running) but does not heat food at all.
No Heat – High-Voltage System Failure
Symptom
Microwave starts then immediately stops within 1–3 seconds; display may return to clock without error code.
Door Interlock or Safety Circuit Trip
Symptom
Microwave turntable does not rotate, but the unit heats and otherwise operates normally.
Turntable Drive Failure
Symptom
Microwave will not start at all; display is blank and no lights or sounds when pressing buttons.
No Power – Primary Power Circuit Failure
Symptom
Over-the-range Kenmore microwave vent fan does not run or runs only on one speed when using the hood function.
