What 0121 means

On Wolf M Series wall ovens such as the SO30 and DO30, 0121 tells you the upper right convection element relay reads shorted. The control reads the third digit as priority. Its partner 0122 covers the lower right convection element relay. Expect the code on the display and convection modes that will not start.

Common causes of 0121

  • Upper right convection element relay stuck closed
  • Control board output for that relay failing
  • Convection element wiring damaged
✓ One safe check you can try

1. Switch the oven off and let it cool. 2. Turn the breaker off for a minute and back on. 3. Try a convection bake cycle once. 4. If 0121 returns or the oven acts oddly, leave it off. 5. Call us; do not remove panels.

! Why to stop there
  • A shorted relay may leave a convection element energized.
  • We test before replacing the relay or board.
  • Your price is written first and repairs have a 30-day workmanship 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.

01210121 questions
What is the upper right convection element?

It is one of the convection heating elements in the oven. Code 0121 means its relay reads shorted. We record what we measured so you can see exactly why a part was recommended.

How is 0121 different from 0122?

0122 is the lower right convection relay with the same shorted condition. The first number refers to the upper right element. When a reset helps only for a while, that pattern is itself useful information for us.

Can I run a normal bake?

It may work, but we suggest not relying on the oven until it is checked. It helps to note how long the code stays and whether it comes back at the same point.
