On legacy Wolf DF dual fuel ranges that show text messages, COMM ERR means communication was lost with the oven controller. The display could not get an answer from the controller that runs the oven, so it shows COMM ERR and the oven may not heat or accept settings. It is similar to CONTROL COM, which adds the flat flex cable as a likely cause.
1. Turn off the oven. 2. Leave the breaker off for a full minute before turning it on. 3. See whether the display responds and COMM ERR clears. 4. If it returns, stop using the oven and call us. 5. Tell us the exact message when you call so we can bring the right parts.
The display lost contact with the oven controller. Without that link, the oven cannot receive your settings or report its status. You see the written price first, so nothing is replaced without your approval.
They describe the same lost-communication condition. CONTROL COM names the flat flex cable and controller as the suspects, so we look at both for either message.
Sometimes, if it was a one-time glitch. If COMM ERR keeps returning, call us and we will quote before any repair. We explain what we find in plain words, so nothing is replaced without your approval.
A technician diagnoses it on site and gives you the price in writing before any work starts.
