General Control System Error
H0
Microwave display shows H0 or HO and the unit will not start; often associated with child lock or safety lock.
Child Lock or Safety Lock Engaged
H1
Microwave shows H1 or HI and stops; may be accompanied by a hot exterior or strong heat from vents.
Overheat Protection Triggered
PF
Microwave display shows PF or Power Fail after an outage; clock may be flashing.
Power Failure Indication
SE
Microwave beeps repeatedly and displays SE; keypad may act as if buttons are being pressed by themselves.
Keypad Short or Stuck Key Error
Symptom
Microwave cavity fills with excessive steam or condensation during cooking, with water droplets forming on walls and door.
Condensation and Ventilation Issue
Symptom
Microwave clock and settings reset to default every time it is unplugged or after brief power interruptions.
Loss of Non-Volatile Memory or Backup Power
Symptom
Microwave completely dead – no display, no interior light, no response to buttons.
No Power – Main Fuse or Power Supply Failure
Symptom
Microwave display is blank or very dim, but the unit still heats when buttons are pressed (if you can guess positions).
Display Backlight or VFD Failure
Symptom
Microwave does not start at all when pressing Start; display and clock work normally.
No Start – Door Interlock or Control Relay Fault
Symptom
Microwave door will not open or is very hard to open after cooking.
Door Latch or Release Mechanism Jammed
Symptom
Microwave door will not stay closed or pops open during operation.
Door Latch Misalignment or Wear
Symptom
Microwave emits a strong burning or electrical smell during or after operation.
Overheating Component or Cavity Contamination
Symptom
Microwave emits a strong chemical or plastic smell when new or after first few uses.
Off-gassing of New Components or Residual Manufacturing Oils
Symptom
Microwave fan runs but there is little or no heating and cooking takes much longer than usual.
Reduced Microwave Power Output
Symptom
Microwave fan runs but there is no airflow from the front or top vents (for built-in/hood combination models).
Blocked or Disconnected Vent Duct
Symptom
Microwave grill function (if equipped) does not heat, but microwave function works normally.
Grill Element or Grill Circuit Failure
Symptom
Microwave interior light does not come on, but the unit heats and operates normally.
Interior Lamp Failure
Symptom
Microwave interior light, fan, and turntable run when the door is open, or continue running after the door is opened.

Symptom
Microwave is very noisy during operation, with vibration or rattling from the cabinet.
Cabinet Vibration or Loose Components
Symptom
Microwave keypad buttons do not respond or only some buttons work.
Partial Keypad Failure
Symptom
Microwave leaks water or condensation onto the countertop or inside the cabinet (for built-in models).
Condensation Drainage or Seal Issue
Symptom
Microwave light, fan, or turntable stay on after the cooking cycle ends and door is closed.
Stuck Relay or Control Board Fault
Symptom
Microwave makes a rattling, grinding, or scraping noise when the turntable rotates.
Turntable Drive or Roller Ring Obstruction
Symptom
Microwave makes loud buzzing or humming noise when running, louder than usual, sometimes accompanied by a burning smell.
High Voltage Component Overload or Arcing
Symptom
Microwave produces sparks or arcing inside the cavity during cooking.
Cavity Arcing – Metal or Damaged Surfaces
Symptom
Microwave runs (light, fan, and turntable operate) but food remains cold or only slightly warm.
No Heat – Magnetron or High Voltage Failure
Symptom
Microwave stops mid-cycle and resets, or display flickers when starting.
Power Supply Instability or Overload
Symptom
Microwave trips the household circuit breaker or RCD as soon as it starts or shortly after.
Short Circuit or Earth Leakage in High Voltage or Mains Circuit
Symptom
Microwave turntable does not rotate, but heating still occurs.
