Wolf E Series Wall Oven Code 4221: Upper or single oven broil element load missing

What 4221 means

Wolf E Series wall ovens, including the SO3050PE/S/P, show 4221 when the broil element load is missing in the upper or single oven. The control powered the broil circuit and saw no load, so it treats the element as disconnected. Owners notice the code on the display, and broil may not heat at all while bake continues to work. The code is shown for the single oven or for the upper oven of a double.

Common causes of 4221

Open or burned-out broil element
Loose terminal at the broil element
Wiring or relay board output for the broil circuit

✓ One safe check you can try

1. Finish or cancel the cycle, then let the oven stand until it is safe to handle. 2. Drop power at the breaker, wait out two minutes, and raise it again. 3. Try a short Bake first, then a short Broil with the door closed to the recommended position, and see which one heats. 4. If 4221 remains, stop using Broil and call us.

! Why to stop there

Broil runs at very high temperature, so we avoid guessing with a loose connection.
Meter testing tells us whether the element or the feed to it has failed.
You get an itemized written quote ahead of time and 30 days of workmanship coverage.

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.

42214221 questions

Why does 4221 say upper or single oven?

The code is for the broil element in a single oven or the upper cavity of a double. A different code covers other cavities. Tell us which oven you use so we plan correctly.

Can I toast or brown with Bake instead?

You can often finish dishes with Bake while the broil element is down, but results differ. Use a lower rack and watch closely, since browning will be slower than normal.

What does the repair usually involve?

Typically we test the element, confirm voltage at the connection, and replace whichever part has failed. You see the written price before any work begins.
