Wolf Legacy E Series Code Error 07 x 4: right convect relay shorted

What Error 07 x 4 means

If a Wolf Legacy E Series oven such as the SO30CE/B/TH and SO30PE/S/PH shows Error 07 x 4, the control has detected a shorted right convect relay. Read the x as the cavity number. The circuit looks stuck closed rather than switching normally. Expect the code on the display and possibly a stopped bake, convection or related function. It names the circuit only, so you do not need to guess at the cause.

Common causes of Error 07 x 4

The right convect relay output on the control board staying closed after the command ends
A loose or damaged wire or connector between the control and the switched load

✓ One safe check you can try

1. Press OFF and let the oven cool completely. 2. Make sure the door closes fully and nothing is wedged in it. 3. Switch the oven breaker off for one minute, then back on. 4. Start a short bake and see whether Error 07 x 4 returns. 5. If it comes back, stop using the oven and call us. Please do not open panels or test wiring yourself.

! Why to stop there

The right convect relay sits in the control circuit, so a measured test tells us whether the board or the wiring is the cause.
Resetting the breaker can clear the display without correcting the condition behind Error 07 x 4.
A 30-day workmanship warranty stands behind whatever we end up repairing.

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 4Error 07 x 4 questions

What does Error 07 x 4 mean on my Wolf oven?

On Legacy E Series wall ovens the code says the right convect relay is shorted. Treat the x as the oven cavity number. It points at one circuit the control checks, not at the whole oven, so other functions may still work normally.

Is it safe to bake while Error 07 x 4 is on the display?

The oven may let you, but the control no longer trusts the right convect relay. We suggest holding off until a technician has checked it, since a circuit that reads wrong can behave unpredictably.

Does Error 07 x 4 need a new control?

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