What F2-03 / F3-03 means

F2-03 and F3-03 turn up on the 30-inch DCS WOSV230 and WODV230 as part of the three-part F code family. These are technical alerts, and the owner's manual does not explain what each number means. They relate to the oven's clock and power electronics, so those boards are the first place we look. You will see the code on the display, and the oven may stop whatever cycle it was running.

Common causes of F2-03 / F3-03

A power board that needs testing
A clock board or its display connection
Loose or damaged wiring between the boards

✓ One safe check you can try

1. Write down the code and the prefix you see. 2. Do not cut power while the fans are running. 3. When they are done and the oven is cool, flip the breaker off. 4. Please do not try to use the oven in the meantime. 5. Give us a call with the model number.

! Why to stop there

The code does not tell us which board to replace, so we test first and avoid replacing parts that work.
We confirm that parts are available for these ovens before the repair starts.
Our quote is written before work begins, and we are honest when a repair is poor value.

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.

F2-03 / F3-03F2-03 / F3-03 questions

What do F2-03 and F3-03 mean?

They are technical alerts in the same family. The owner's manual does not give each number its own meaning, so testing is the only way to learn what raised it.

Why wait for the fans?

The fans carry heat out of the oven. If power is cut while they run, the oven cools more slowly, so let them finish first.

Do I need to replace the oven?

Not necessarily. We test, confirm parts, and give you a written price. Only if the repair does not make sense do we suggest a replacement.
