Wolf Dual Fuel Range DFxx50 Code 3311: Upper thermal cutout open

What 3311 means

On Wolf DFxx50 dual fuel ranges from 2020 on, such as the DF30450/S/P and DF36450G/S/P, code 3311 means the upper thermal cutout (TCO) is open. A TCO is a safety device that opens when the oven cavity gets too hot, and the control reads it as open. You will see 3311, and heating in the upper oven stops until the condition is resolved.

Common causes of 3311

Oven that overheated and tripped the thermal cutout
Cooling fan or airflow problem that let the oven run too hot
Thermal cutout that has opened permanently or has a loose connection

✓ One safe check you can try

1. Turn the oven off and let it cool for at least an hour. 2. Remove foil or pans that block vents or the oven floor. 3. Toggle the breaker off for a minute and back on. 4. If 3311 returns after the oven is cool, stop using it and call us.

! Why to stop there

A thermal cutout opens for a reason, so we find out what overheated before replacing it.
Bypassing a safety device is dangerous, and we will not do that.
You see a written price first, and the repair carries a 30-day 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.

33113311 questions

What is the TCO on my Wolf range?

It is a thermal cutout, a safety switch that opens at high temperature. Code 3311 says the upper one reads open, so the control stops upper-oven heating.

Why did it trip?

Common reasons are poor airflow, a cooling problem, or a failure in the cutout itself. We check airflow and the cutout circuit to see which, then quote before work.

Can I reset it and keep going?

A reset only clears the message. If the cutout has opened for real, heating will not resume safely. Call us rather than testing repeatedly. You see the written price first, and we tell you the result of each check.
