Wolf Legacy E Series Code Error 07 x 22: light relay open

What Error 07 x 22 means

Owners of Legacy E Series Wolf wall ovens like the SO30TE/S/TH and DO30PE/S/PH may meet Error 07 x 22. It is an open reading on the light relay, and the x marks the cavity it came from. Put simply, the control finds a broken path where a working switch belongs. The display shows the code, and the related oven function can stop working.

Common causes of Error 07 x 22

The light relay output on the control board not switching as commanded
A bad connection on the harness running to the oven lamp
The oven lamp itself no longer completing the circuit

✓ One safe check you can try

1. Turn the oven off and wait until the cavity is cool to the touch. 2. Close the door firmly and wipe any debris from its seal. 3. Reset power at the breaker after a one-minute pause. 4. Try a short preheat and note whether Error 07 x 22 shows again. 5. A repeat means the circuit needs testing, so stop using the oven and call us.

! Why to stop there

A reading on the light relay can come from the board, the harness or the load, and only measuring separates them.
Running the oven again and again with Error 07 x 22 showing can stress other parts of the control.
Our visit starts with a written estimate, and the finished repair comes with 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.

Error 07 x 22Error 07 x 22 questions

What is Error 07 x 22 telling me?

It is a status from the control about the light relay, which it reads as open. The x refers to the cavity involved. It does not say the whole oven has failed, only that this one circuit needs attention.

Should I wait it out when Error 07 x 22 appears?

Waiting for the oven to cool is fine, but a code about the light relay will not fix itself. If it returns after cooling, plan on a visit rather than working around it.

Does Error 07 x 22 need a new control?

Not necessarily. The wiring or the part itself can cause a light relay reading as easily as the board. We test first, then tell you what is needed and what it costs in writing.
