Wolf Legacy E Series Code Error 07 x 23: DLB1 relay or TCO open

What Error 07 x 23 means

On Wolf Legacy E Series wall ovens such as the SO30CE/B/TH and DO30TE/S/TH, Error 07 x 23 tells us the control sees the DLB1 relay or TCO as open. The x in the code is the cavity digit. In plain words, the circuit that should switch this part on is not completing when the oven asks for it. The code appears in the display, and the matching function may not run until the condition is cleared.

Common causes of Error 07 x 23

The DLB1 relay or TCO circuit reading open on the control
Poor contact in the connector that feeds the door-lock circuit
A control board output that is no longer closing when called on

✓ One safe check you can try

1. Stop the cycle with OFF and let the heat drop. 2. Look over the door and hinges for anything that keeps it from closing. 3. Cut power at the breaker, count to sixty, and restore it. 4. Set a modest bake temperature and wait to see if Error 07 x 23 comes back. 5. If it does, do not keep trying; call us and leave every panel closed.

! Why to stop there

The oven's own circuit check flagged the DLB1 relay or TCO, which is a reason to confirm with instruments.
A cleared display after a power cycle does not mean Error 07 x 23 has been fixed.
Nothing is started until you have approved the written price in hand.

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 23Error 07 x 23 questions

I see Error 07 x 23. Is the DLB1 relay or TCO the problem?

Yes, that is the circuit the code names. The control reads it as open, but the cause could be the part, the wiring or the board output, which is why we test before replacing anything.

Is Error 07 x 23 an emergency?

Not usually, but it is not something to ignore either. Turn the oven off, let it cool, and if the code stays, call us. We would rather diagnose than have you cook through it.

How long does an Error 07 x 23 repair take?

Many visits are done in a single trip, when the part is on the truck. If something must be ordered, we explain that before leaving and you decide whether to proceed.
