Short Circuit in High-Voltage or Heater Circuit
E14
Microwave shows E14 and the turntable does not rotate, even though heating may still occur.
Turntable Motor or Position Sensor Fault
E15
Microwave displays E15 and may not respond to certain function selections, especially combination or convection modes.
Mode Relay or Function Selection Fault
E16
Microwave shows E16 and may shut down or refuse to start after a door open/close sequence.
Door Sense Logic Error
E17
Microwave displays E17 and the interior light does not come on when the door is opened, though other functions may work.
Cavity Lamp or Lamp Circuit Fault
E18
Microwave shows E18 and may emit a continuous beep; clock and settings may reset unexpectedly.
Power Supply Voltage Fluctuation Detected
E19
Microwave displays E19 and convection or combination modes fail to start or stop prematurely.
Convection Heater or Fan Fault (Convection Models)
E20
Microwave shows E20 and sensor-based defrost or reheat programs terminate early or do not start.
Weight / Load Sensor or Algorithm Fault
Symptom
Microwave clock and display reset to 0:00 or flash after each use or randomly during the day.
Intermittent Power Loss to Control Board
Symptom
Microwave convection or grill mode takes excessively long to reach temperature or does not brown food properly.
Reduced Heating in Grill/Convection System
Symptom
Microwave display and clock are on, but pressing any keypad buttons has no effect; unit will not start.
Unresponsive Keypad / Control Panel
Symptom
Microwave display is completely dead; no lights, no response when plugged in.
No Power – Primary Supply Failure
Symptom
Microwave display works, but the START button does nothing; other buttons (clock, power level) respond normally.
Single Key Failure on Membrane Keypad
Symptom
Microwave door glass or outer surface becomes excessively hot to the touch during normal microwave-only operation.
Overheating Door / Insufficient Ventilation
Symptom
Microwave door will not open or is very difficult to open after cooking.
Door Latch / Release Mechanism Jammed
Symptom
Microwave door will not stay closed or pops open during cooking.
Door Latch Retention Failure
Symptom
Microwave emits a strong burning or electrical smell during or after operation.
Overheating Component or Wiring
Symptom
Microwave emits loud popping noises and flashes when certain foods are cooked, even without metal present.
Food-Related Arcing / Splatter Ignition
Symptom
Microwave heats but makes a loud buzzing or humming noise that is much louder than normal during operation.
Noisy High-Voltage Transformer or Magnetron
Symptom
Microwave interior light does not come on, but the unit heats and otherwise works normally.
Failed Cavity Lamp
Symptom
Microwave interior light turns on and fan may run, but the turntable does not rotate; food heats unevenly.
Turntable Drive Failure
Symptom
Microwave leaks water or condensation onto the worktop or inside the cabinet after use.
Condensation Management / Door Seal Issue
Symptom
Microwave makes rattling, grinding, or scraping noises during operation.
Mechanical Noise – Turntable or Fan
Symptom
Microwave produces uneven heating; some areas of food are boiling while others remain cold.
Uneven Energy Distribution
Symptom
Microwave runs but does not heat food at all; light and turntable operate normally, no error code displayed.
No Heating – High Voltage System Failure
Symptom
Microwave runs for a few seconds and then stops, returning to the clock display without heating the food.
Premature Cycle Termination
Symptom
Microwave trips the household circuit breaker or blows a fuse as soon as START is pressed.
Internal Short Circuit Under Load
Symptom
Visible sparks or arcing inside the microwave cavity during cooking, often near the waveguide cover or metal objects.
Cavity Arcing / Waveguide Contamination
