Fisher & Paykel Induction Cooktop Code E9: temperature sensor replacement

What E9 means

Fisher & Paykel CI304DTB4, CI244DTB4 and CI365DTB4 induction cooktops list E9 in the cook zone table with the action to change the temperature sensor. That sensor watches the heat under the glass so the cooktop can protect the zone from overheating. When it is not reading properly, owners see E9 and the zone typically cuts power until the sensor is replaced.

Common causes of E9

Temperature sensor under the zone has stopped reading
Sensor wiring that has loosened or been damaged
Heat damage to the sensor after the zone ran dry or empty

✓ One safe check you can try

1. Switch the zones off and let the glass cool completely. 2. Remove any pan and wipe the surface clean. 3. Reset the cooktop at its breaker, off for one minute and then on. 4. If E9 shows again, do not keep heating the zone. Call us and leave the glass in place.

! Why to stop there

Running the zone with a bad temperature reading removes the overheating protection, so continued use is a risk.
The sensor sits below the glass beside live electronics.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E9E9 questions

What does the temperature sensor do?

It tells the cooktop how hot the glass and coil area are, so it can lower or cut power before anything overheats. E9 means the published action is to replace that sensor.

Should I keep cooking until the part arrives?

We advise against it. Without a reliable temperature reading, the cooktop cannot guard the zone properly, so it is safer to leave that zone off until the sensor is replaced.

Will a reset make E9 go away?

A reset can clear the display for a moment, but if the sensor itself has failed the code returns the next time the zone heats. We test and replace it on site with a written price first.
