Induction Cooktop F8 Error: Causes & Fixes

What does the F8 error mean on an induction cooktop?#

F8 signals that a switching relay inside the controller has failed, usually in the aftermath of a supply disturbance — a surge, a sag in voltage, or a nearby lightning strike on the home's power. The cause sits outside the appliance, so the useful first thing to review is not the cooktop but the recent behaviour of your electricity: a storm, a utility fault, or repeated dips just before the code appeared. It is documented on GE and GE-built cooktops and ranges, including GE Profile and Café models. The table below lays out the causes, which centre on a relay that a voltage spike has welded or damaged, alongside the shaky-supply conditions that bring it on.

F8 on an induction cooktop: what it means and what to check#

An induction cooktop shows F8 when a relay on the control board has failed, typically after a power surge, brown-out, or lightning event.

How to clear the F8 error yourself#

Give it one restart: switch off at the breaker for a minute and back on, in case the fault merely latched rather than the relay failing for good. That is where the safe owner step ends, because a welded or spike-damaged relay lives inside the sealed controller and is no place for home repair. What sets this code apart from the purely internal ones is the supply angle. If the cooktop feeds from a circuit prone to voltage dips, or the code followed a storm, the electrical environment is part of the story, and a licensed electrician should inspect the circuit and weigh adding surge protection. Repair the relay while leaving a shaky supply untouched and the fault tends to come straight back. So: one restart, then a technician for the relay and, where the supply is suspect, an electrician for the circuit.

When the F8 error needs a technician#

This code usually calls for both trades in turn. The relay itself — welded or spike-damaged so it can no longer switch a zone properly — is a controller repair a technician makes with the right part and service diagnostics, never an owner fix. Separately, if the disturbance that caused it reflects an unreliable supply, a licensed electrician should verify the circuit and fit surge protection so a fresh relay does not meet the same end. An isolated storm may need only the relay repaired, but repeated voltage dips make the electrician's inspection as important as the cooktop repair itself.

Induction cooktop F8 error: frequently asked questions#

What does the F8 error mean on an induction cooktop?#

It points to a switching relay inside the controller failing, typically after a surge, a voltage dip, or a lightning event on the home's supply. The trigger comes from outside the appliance. A restart may shake off a latched fault, but a genuinely damaged relay needs a technician to replace it.

Can a relay welded by a voltage spike trigger the F8 error?#

Yes — that is the heart of it. A spike can fuse the relay closed or ruin its contacts so it no longer switches a zone correctly, and the controller flags the code. Since the part sits inside the sealed unit, swapping it is a technician's repair rather than anything an owner should attempt.

Does lightning or grid-switching damage cause the F8 code on an induction cooktop?#

It can. A strike on the supply, or switching transients from the grid, can drive a spike into the cooktop and harm the switching relay, producing the code. That is why it so often trails a storm or a utility event, and why surge protection is worth weighing once the part is repaired.

Should I check for recurring brown-outs on the supply first?#

Yes, look at the supply history. If the cooktop's circuit suffers repeated voltage dips, that unstable power is the likely culprit behind the damage, and a replacement part stays at risk until it is sorted. A licensed electrician should examine the circuit and add surge protection alongside the appliance repair.

Can I clear the F8 error myself?#

Only by trying a single restart to shed a latched fault. A relay actually harmed by a spike cannot be mended at home, since it is buried in the sealed controller. If the code lingers after a restart, it needs a technician for the part and, where voltage dips are involved, an electrician for the circuit.

Is it safe to keep cooking when F8 shows?#

No. A failed or welded relay can leave a zone switching wrongly, so a cooktop displaying this code should not be trusted. Try one restart, and if it holds, leave the appliance off until a technician has fitted a new relay — and have the supply examined if surges or dips played a part.
