Wolf CT Induction Cooktop Code E44: RL burner sensor reads open

What E44 means

On the earlier Wolf CT induction cooktops, such as the CT30I/S and CT36I/S, E44 reports that the generator sensor for the RL burner reads open. The control cannot see a temperature signal from that burner, so it shuts that burner down to protect the glass and electronics. You will see E44 and that one burner will not heat. The remaining burners usually keep working normally.

Common causes of E44

Open temperature sensor circuit at the RL burner
Loose or damaged sensor connection under the glass
Generator board not reading the sensor

✓ One safe check you can try

1. Turn off every zone and allow the cooktop to cool fully. 2. Turn the wall breaker off for one minute, then turn it on again. 3. Clean the glass and test the other burners with a flat magnetic pan. 4. If the RL burner stays dead or E44 reappears, schedule service. Do not lift the glass or probe any wiring.

! Why to stop there

Sensors sit beneath the ceramic glass, and reaching them means careful disassembly.
Swapping parts by guesswork can cost more than the diagnosis, so we test first.
Expect a written price first.
Our visit carries a 30-day workmanship warranty.

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.

E44E44 questions

Which burner is the RL burner?

RL is the burner position as the control labels it. E44 refers to that burner's sensor circuit, and the other burners can keep working because each one has its own sensor circuit.

Why did only one burner shut off?

The control isolates the burner whose sensor it cannot read. That is a safety choice, so the cooktop protects itself instead of heating blindly, while cooking can continue on the other burners.

Is the glass cracked if I see E44?

No. E44 is an electrical reading, not a glass break. We still check the glass surface during the visit so nothing is overlooked, and we tell you what we find.
