What does Wolf dual fuel range error code 3311 or 3312 mean?
On Wolf 30" and 36" dual fuel ranges, error code 3311 (single or right oven) or 3312 (left oven) means "TCO Open." The thermal cutoff opened because of excessive temperature or a wiring issue, so the oven may stop heating or shut off. Wolf lists it as top priority. A technician must check the TCO and wiring.
What the code means
Wolf's ICB dual fuel range service manual lists 3311 and 3312 as "TCO Open" (priority 1): the TCO has opened due to excessive temperature or a wiring issue. 3311 is the single or right oven, and 3312 is the left oven. Wolf's service instructions are to check the TCO circuit, check the terminal block wiring, and replace the TCO.
Safe homeowner checks
- Turn the oven off and let it cool completely.
- Write down the code and which oven it applies to.
- Stop using the oven until it has been checked.
- Do not open panels, test wiring, or replace parts yourself.
When to call a technician
Call a technician right away. TCO, terminal block and line-voltage wiring work on a dual fuel (gas) range is technician-only.
