H01
Panasonic built-in oven will not heat; display and fan operate but cavity remains cold in all cooking modes.
Open or failed upper heating element circuit
H02
Oven does not heat in fan-forced or convection mode; fan runs but temperature does not rise.
Convection (fan) heater failure
H03
Oven overheats rapidly, burning food even at low temperature settings; temperature seems uncontrollable.
Oven temperature sensor (NTC) failure or short
H04
Oven does not heat at all in any mode; display works, interior light may work, but no heating elements energize.
Main heater power relay or power board failure
H05
Oven displays an overheat or safety error shortly after starting, then shuts down and may cool with fan running.
Cavity over-temperature protection triggered
H11
Oven display shows a communication error; some functions may be disabled or unresponsive.
Communication failure between user interface board and main control board
H12
Oven display is blank or flickering, but interior light may still work; buttons may not respond.
Low-voltage power supply failure on control PCB
H21
Oven fan does not run in convection mode; error displayed and heating may be disabled.
Convection fan motor failure
H27
Oven door lock error; self-clean or pyrolytic cycle will not start, or oven reports door lock fault.
Door lock mechanism or switch failure
H32
Oven displays a sensor error and may not start heating; temperature cannot be set correctly.
Open or disconnected oven temperature sensor
H41
Oven interior light does not turn on; error may indicate lamp circuit fault on some models.
Oven cavity lamp circuit failure
H50
Oven displays a generic system error and becomes unresponsive or stuck in standby.
Control firmware or EEPROM corruption
H71
Oven displays a door open/close error even when the door is properly shut; cooking will not start.
Door switch or latch sensor failure
H98
Combination Panasonic oven (microwave + convection) shows H98 and microwave function does not work, though oven heating may still operate.
Inverter or magnetron failure (microwave section)
H99
Combination oven shows H99 and will not start microwave or combination cooking modes.
Microwave safety interlock or door sensing failure
Symptom
Combination oven’s microwave function runs but does not heat food; no specific error code displayed.
Microwave high-voltage circuit partial failure
Symptom
Oven cavity light stays on all the time, even when the door is closed and oven is off.
Stuck lamp relay or door switch not detecting closure
Symptom
Oven clock and timer function, but interior light does not turn on when the door is opened.
Door switch or lamp circuit issue
Symptom
Oven display and clock reset randomly or flicker when the oven heats up.
Thermal stress on control electronics or unstable power supply
Symptom
Oven display shows child lock symbol and controls do not respond.
Child lock function engaged
Symptom
Oven does not heat evenly; food is burnt at the back and undercooked at the front in convection mode.
Airflow imbalance or convection fan performance degradation
Symptom
Oven does not power on at all; no display, no light, completely dead.
Primary power supply or safety device failure
Symptom
Oven door glass has condensation or moisture between the panes during or after cooking.
Compromised door glass seal or blocked vent path
Symptom
Oven door glass is excessively hot to touch during normal baking cycles.
Cooling airflow or door insulation degradation
Symptom
Oven door will not close fully; heat escapes and temperature is unstable.
Door hinge or door seal misalignment
Symptom
Oven emits a strong burning smell or smoke during use, even after initial burn-in.
Contamination or overheating of internal components
Symptom
Oven enamel or interior coating is flaking or chipping, exposing metal underneath.
Cavity enamel degradation
Symptom
Oven fan continues to run for an unusually long time after the oven is turned off.
Cooling fan overrun or thermostat sticking
Symptom
Oven grill function does not brown food; top element glows weakly or not at all.
Grill element or grill circuit failure
Symptom
Oven light and display work, but oven will not start heating when a program is selected; no error code shown.
User interface input or start circuit failure
Symptom
Oven lower element does not heat; bottom of food remains pale while top browns.
Bottom heating element failure
Symptom
Oven makes loud rattling or grinding noises when the fan is running.
Mechanical wear or obstruction in fan system
Symptom
Oven selector knob is loose, skips positions, or does not register mode changes.
Worn rotary selector or broken knob shaft
Symptom
Oven takes excessively long to preheat and struggles to reach set temperature.
Reduced heating capacity or partial element failure
Symptom
Oven temperature is consistently lower than the set value; food takes longer to cook than recipes indicate.
Temperature calibration drift or sensor inaccuracy
Symptom
Oven temperature is higher than the set value; food burns on the outside while undercooked inside.
Over-reading temperature sensor or control calibration error
Symptom
Oven trips the household circuit breaker or RCD when heating is started.
Earth leakage or short circuit in heating circuit
