Is it safe to keep using it?

Depends on code severity. Low/Medium codes often allow continued use, High severity requires immediate stop.

Can error codes be reset?

Some codes clear after power cycle. Persistent codes indicate underlying issues needing repair.

When should I stop using it?

Stop immediately for water leak codes, burning smell, or any High severity error.

Low Medium High

Code Meaning Severity Common Symptom

30:150 Meat probe jack short circuit Medium The oven cavity may heat initially but then cuts off as the control board detects the abnormal probe jack signal and triggers a protective shutdown to prevent sensor-circuit damage. View 77:150 Meat probe circuit fault Medium The oven heats initially but cannot sustain the target temperature, cutting off mid-cycle as the probe circuit fault interferes with the control board's temperature regulation loop. View E2 Induction zone overtemp Medium The zone stops heating mid-cook without warning during sustained high-power use, particularly when cooking with large pots at maximum power for extended periods. View E4 Broiler temp sensor fault Medium Selecting the broil function produces no heat from the upper element, or the oven begins broiling but cuts off partway through as the control board detects an invalid signal from the broiler probe. View FAULT-BROILER-KNOB Broiler temp knob mis-set Low The burner or element fails to produce any heat when broil is selected, because the control circuit requires the temperature knob to be set to exactly 500 °F before it will energise the broil element or burner. View FAULT-CLEAN Self-clean power interrupted Medium After mains power is restored the door latch does not retract, because the oven must cool below 500 °F before the latch motor will release — a process the interrupted cycle cannot restart automatically. View FAULT-CLEAN-STOP Self-clean cancelled early Low Moving either the function or temperature selector during a self-clean cycle does not immediately unlock the door — the latch motor holds the door closed until the cavity temperature drops to the safe threshold. View FAULT-FAN Cooling fan motor failure High Selecting any bake or broil function causes the PRE-HEATING LED to flash immediately with an audible alarm rather than beginning a normal preheat cycle, as the control board detects the cooling fan has not started. View FAULT-TEMP Temp sensor probe failure High The oven cavity fails to reach the dialled temperature and cuts heating entirely, leaving food undercooked. The fault is repeatable across all bake and convection modes. View LV4 Control board comm fault Medium All cooking functions become unresponsive after LV4 appears — neither the oven cavity nor any induction zone will activate, because the control board has locked itself out pending a fault-clearance sequence.
