Fisher & Paykel Cooktop Error Code F12.6

F12.6 indicates that the cooling fan voltage is out of the allowable range. The main PCB monitors fan voltage through its ADC, and if the reading stays above 28V or below 2V for 10 seconds, this fault is triggered. The cooktop stops operating to protect the electronics from heat damage caused by inadequate cooling.

No. The cooling fan protects the power electronics and main PCB from overheating during use. Operating the cooktop without a functioning fan circuit risks permanent damage to internal components and could create a fire or electrical hazard. The cooktop should remain off until the fault is diagnosed and resolved.

Repair costs depend on the failed component. A replacement cooling fan typically costs between $30 and $80 in parts, while a new main PCB can range from $150 to $400 or more depending on the model. Adding a technician's labor, total repair costs generally fall somewhere between $100 and $500, with PCB replacement representing the higher end of that range.

Some causes, such as a loose connector or a disconnected fan harness, can be addressed by a confident DIYer who is comfortable working with appliance electronics. However, diagnosing whether the fault lies in the fan motor, the wiring, or the main PCB requires a multimeter and knowledge of how to safely access the cooktop internals. If the main PCB needs replacement, professional service is strongly recommended.

A power cycle may temporarily clear the error display, but if the underlying fault in the fan or fan circuit is still present, F12.6 will return within 10 seconds of the condition recurring. Resetting is useful for confirming whether the fault is intermittent, but it does not fix the root cause.
