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

CLICK-NO-IGN Clicking but no flame Medium Turning the burner knob to the light position produces a clear, rapid clicking sound from the ignition module, but the burner never catches and no flame is visible. View CONT-SPARK Continuous sparking Medium The cooktop produces continuous rapid clicking sounds from the ignition module even though no burner knob has been turned, which is the defining observable symptom of CONT-SPARK. View F1 Ignition module fault High The cooktop control panel displays F1 and no ignition spark is produced when a burner knob is turned to the light position. View F3 Flame supervision failure High The burner lights normally and burns for 2–10 seconds, then the gas valve closes and the display shows F3, indicating the flame sensor did not confirm a stable signal. View F4 Gas valve error High Selecting a burner produces a spark but no gas flow, and the display immediately shows F4 as the control board reports a gas valve fault. View GAS-SMELL Gas odor detected High Natural gas and propane are odorized with mercaptan, producing a distinct sulfur or rotten-egg smell. Any detection of this odor near the cooktop must be treated as a gas leak until proven otherwise. View LOW-FLAME Weak burner flame Medium At maximum knob setting the burner flame is visibly lower than expected — typically less than half the height of a properly functioning burner on the same cooktop. View NO-IGN Burner won't ignite Medium Turning the burner knob to the light position produces clicking from the igniter but the burner never ignites, and after several seconds the control board stops the sequence and shows NO-IGN. View PF Power failure detected Low The control panel shows PF immediately when power returns after an outage or breaker trip — the most common and expected presentation of this code. View YELLOW-FL Yellow or sooty flame Medium The normally blue cone flame is replaced by a tall, flickering yellow or orange flame across all or part of the burner ring — the most reliable observable indicator of combustion problems.
