Wolf Legacy E Series Code Error 03 x 4: Right element not detected

What Error 03 x 4 means

Error 03 x 4 appears on Wolf Legacy E Series wall ovens, including the SO30TE/S/TH, and the official wording is No Rt Element Detect. The control does not see the right-side element drawing power. Cooking may slow down or stop, and the code stays on the display until the oven is checked. The cavity number takes the place of the x on the display.

Common causes of Error 03 x 4

Right-side element open or burned out
Element wire or terminal connection loose
Relay not powering the right-side element

✓ One safe check you can try

1. Switch the oven off and keep the door closed while it cools. 2. Try a plain bake at a moderate temperature. 3. Leave the breaker off for one minute and then power the oven back up. 4. If Error 03 x 4 keeps returning, stop cooking and call us.

! Why to stop there

Heating elements run on high current, and the connections are behind panels.
Telling an element failure from a relay failure takes a meter and the right access.
We state the price in writing before work begins.
Workmanship is warranted for 30 days after we finish.

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 03 x 4Error 03 x 4 questions

Which element is the right one?

The code names the right-hand element, the counterpart of the left convection element covered by Error 03 x 3. We check the matching circuit and its relay first.

Will the oven heat at all?

Sometimes it heats on the remaining elements, but slowly or unevenly. The control still reports the missing element, so the code does not clear on its own.

Do I need to replace the whole oven?

No. A missing element is a repairable condition. We confirm the cause and give you a written price before any part is ordered. That keeps the repair short and the bill honest.
