Wolf Legacy E Series Code Error 07 x 12: Auxiliary DLB output shorted

What Error 07 x 12 means

Error 07 x 12 shows on Wolf Legacy E Series wall ovens such as the DO30TE/S/TH and means Aux DLB Shorted. The auxiliary DLB circuit reads shorted to the control. The oven may refuse to run, and the display keeps the code until the circuit is repaired. In the code the x is a placeholder, and the real display gives the cavity number.

Common causes of Error 07 x 12

Auxiliary DLB output or load shorted
Wire in the auxiliary circuit damaged
Control output failing

✓ One safe check you can try

1. Turn the control to off, then wait about thirty minutes. 2. Confirm the door is fully closed with nothing in the seal. 3. Power-cycle the oven at the breaker, leaving it off for one minute. 4. Try a short bake. If Error 07 x 12 returns, stop using the oven and call us.

! Why to stop there

The auxiliary circuit runs through the oven body and control, which owners should not open.
A short can sit in the load, the wiring, or the control output.
We quote in writing before any part is ordered.
The repair is guaranteed for 30 days against workmanship issues.

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 12Error 07 x 12 questions

Is this linked to Error 07 0 25?

Yes. Error 07 0 25 says the auxiliary DLB is open, and Error 07 x 12 says it is shorted. We test the same circuit for either code.

What does Aux mean?

Aux is the label for the auxiliary DLB circuit, kept as the display prints it. It is separate from DLB1 and DLB2. We keep the visit focused on that one circuit.

Can it be a loose wire?

A loose wire usually reads open, not shorted. A shorted reading means something is touching or has failed, which we confirm with a meter. It is a common starting point for us.
