Fisher & Paykel Cooktops E1 Error: Inverter overheating
Fisher & Paykel cooktop error code E1 is a high-severity fault meaning Induction inverter / IGBT over-temperature fault. An E1 inverter fault indicates the power electronics reached a critical temperature. The fault clears automatically after the inverter cools.

Answer to continue safely
Is it safe to keep using?
No. An E1 inverter fault indicates the power electronics reached a critical temperature. Do not continue using the affected zone until the root cause is resolved. Using an overheating inverter risks permanent IGBT damage and, in extreme cases, fire.
Can I reset the code?
Yes. The fault clears automatically after the inverter cools. If E1 returns within a few minutes of restarting, there is a mechanical or electrical problem that requires service — repeated thermal cycling will destroy the IGBT.
When to stop immediately?
Stop if you notice: E1 returns within minutes of every restart, Any burning smell or discolouration on the glass-ceramic surface.
Symptoms You May Notice
E1 displayed and zone shuts off
The affected induction zone powers down immediately and displays E1; the remaining zones may stay active.
Cooling fan audible but zone unresponsive
The internal cooling fan runs at full speed but the zone refuses to restart until the fault clears.
Repeated shutdowns during high-power use
The fault triggers consistently when operating a large zone at power level 8 or above for extended periods.
Possible Causes
Blocked ventilation slots
Grease or debris blocking the underside ventilation slots prevents airflow across the IGBT heat sink, causing the inverter to overheat.
DIY PossibleFailed or obstructed cooling fan
The inverter cooling fan has seized or a foreign object is restricting its blades, eliminating forced airflow over the power electronics.
Requires ProfessionalFaulty IGBT module
The insulated-gate bipolar transistor driving the induction coil has partially failed and now generates excess heat even at moderate power levels.
Requires ProfessionalExcessive ambient temperature under cooktop
Inadequate clearance between the cooktop and the cabinet below, or a nearby oven venting heat into the cavity, raises the baseline temperature above the inverter's thermal limit.
DIY PossibleSafe Checks You Can Do
-
1
Switch off and allow to cool
Turn the cooktop off at the controls and leave it unused for at least 20 minutes before attempting to restart the affected zone.
The thermal cutout resets automatically once the IGBT temperature drops below the safe threshold.
-
2
Clear ventilation slots
Inspect the underside of the cooktop and the surrounding cabinet cutout for grease buildup or debris blocking the ventilation openings. Clean with a soft brush.
Fisher & Paykel induction cooktops require a minimum 5 mm clearance beneath the unit — confirm this in your installation manual.
-
3
Check cabinet cavity temperature
If an oven is installed below the cooktop, ensure the anti-heat baffle or insulation between the two appliances is intact and in place.
Run the cooktop with the oven off to confirm whether oven heat is contributing to the fault.
-
4
Listen for fan operation
With the cooktop powered on at a medium setting, listen for the inverter fan. Absence of fan noise suggests a failed fan motor requiring professional replacement.
Do not attempt to reach under a live cooktop to inspect the fan.
When to Call a Professional
Contact a qualified technician if:
- Cooling fan replacement requires disassembling the inverter module
- IGBT replacement involves soldering high-current power electronics
- Persistent E1 after clearing ventilation suggests internal board fault
