Wolf Legacy E Series Code Error 07 x 9: light relay shorted

What Error 07 x 9 means

Wolf Legacy E Series wall ovens, the SO30PE/S/PH and SO30TE/S/TH among them, display Error 07 x 9 when the light relay reads as shorted. The x identifies the cavity. Instead of opening on command, the circuit looks closed. That leaves you with a code on the screen and a function that the oven may refuse to run. It concerns the oven lamp circuit, which is why the light may behave oddly.

✓ One safe check you can try

1. Switch the oven off and allow plenty of cooling time. 2. Check that the door seals evenly all the way around. 3. Reset the supply by turning the breaker off for sixty seconds. 4. Try a quick bake and see if Error 07 x 9 is displayed again. 5. Persistent codes need a technician. Please keep your hands out of the wiring and call us.

! Why to stop there

We would rather prove which part is behind the light relay reading than replace parts in turn.
The code is stored for a reason, and Error 07 x 9 deserves a proper look rather than another reset.
Approval of a written quote comes first, work second, and a 30-day warranty follows.

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 9Error 07 x 9 questions

Does Error 07 x 9 point to the whole oven or one part?

One part. The code names the light relay, which the control reads as shorted. The rest of the oven may be fine, though the function tied to that part can be blocked until it is repaired.

Can I keep using the oven with Error 07 x 9 showing?

That depends on the part involved, and the oven may already block the related function. We would rather you stop and call than run a cycle while the control is unsure about this circuit.

How do I get rid of Error 07 x 9?

Let the oven cool and cycle the breaker once. If the code comes back, the light relay needs testing by a technician. That is the only reliable way to clear it for good.
