Wolf M Series Wall Oven Code 2930: Relay board conversion circuit error

What 2930 means

On Wolf M Series wall ovens such as the SO30TM/S/TH, code 2930 points to the relay board conversion circuit. The board has detected an error in the circuit that converts signals between the relay board and the rest of the control. The display shows 2930, and the oven may stop heating or ignore new settings until power is cycled. The controls may still light up, yet cooking commands are not carried out until the circuit is repaired.

Common causes of 2930

Conversion circuit on the relay board
Poor connection on the relay board harness
Control board that is not receiving the converted signal correctly

✓ One safe check you can try

1. Stop any cycle and give the oven time to cool down. 2. Shut the breaker off, count out two minutes, and turn it back on. 3. Run a short Bake to see if the display stays clear. 4. If 2930 comes back, keep the oven off and call; the relay board is behind panels that should stay closed.

! Why to stop there

Board-level circuits cannot be judged by looking, so we test with a meter and carry parts.
Repeated resets can stress the control while the real problem remains.
Our estimate is written down up front, so there are no surprises, and the finished repair has a 30-day 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.

29302930 questions

What is a conversion circuit?

It is the part of the relay board that translates signals between the electronics and the loads the oven switches. When it reports an error, the oven cannot be sure its commands are being carried out.

Will 2930 go away on its own?

It can appear to after a power reset, but it tends to return because the board has detected a real error. Treat a repeat as a repair need rather than relying on resets.

Is the whole control replaced for 2930?

Usually the relay board is the first part we test. We confirm which board is to blame with measurements before quoting, so you only pay for what the oven needs.
