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.

Meaning
Severity
Common Symptom
ERR
General system error
Medium
The control panel shows ERR and prevents any oven function from starting until the error is cleared by a reset.
View
F1
Watchdog timer fault
High
The alphanumeric display cycles the F1 code repeatedly and all cooking functions become unresponsive.
View
F2
High temperature alarm
High
The bake or broil element de-energizes automatically and the display shows F2, often accompanied by a continuous alarm beep.
View
F3
Shorted temp sensor
High
The control panel shows F3 as soon as the range is powered on, before any cooking function is selected, indicating a persistent sensor fault.
View
F4
Open temp sensor circuit
High
The range displays F4 and refuses to energize the oven elements — the board will not heat without a valid sensor signal.
View
F7
Door lock over-temp fault
Medium
The self-clean cycle aborts partway through, the display shows F7, and the door remains locked until the oven cavity cools below the unlock threshold.
View
F8
Door lock switch fault
Medium
The self-clean cycle fails to initiate, displaying F8 immediately — the board cannot confirm the door is locked and refuses to proceed.
View
F9
Door lock motor jammed
Medium
The most common presentation: the door lock motor stalls partway through its travel and F9 appears, leaving the door in a partially locked state.
View
F10
Control board comm error
High
Some or all oven functions stop responding while the display shows F10 — surface burners may still work since they do not depend on the communication bus.
View
GAS-SMELL
Gas odor near range
High
Natural gas is odorized with mercaptan, producing a distinctive sulfur smell. Any perception of this odor near the range must be taken seriously and acted upon immediately.
View
NO-IGN
Burner ignition failure
Medium
The igniter sparks repeatedly for several seconds but the burner flame does not establish. After the retry period, NO-IGN is displayed and the gas valve closes.
View
PF
Power failure detected
Low
The range powers back on after an outage and shows PF on the display. No other functions are affected once the code is acknowledged.
View
SLOW-HEAT
Oven slow to preheat
Medium
An independent oven thermometer confirms the cavity is heating but is lagging significantly behind the expected preheat time, indicating reduced burner output or heat retention.
