Wolf M Series Code 1F22: Both Lower Broil Element DLBs Open, Weak or No Broil

What 1F22 means

On Wolf M Series wall ovens, including the SO30TM and DO30PM lines and the 2019 and later SO3050 models, code 1F22 reports that both DLBs for the lower broil element are open. Both line-break paths in the broil circuit read as open to the control. You will see 1F22 on the display, and the lower oven will broil weakly or not at all.

Common causes of 1F22

Both lower broil DLB paths open
Shared wiring in the broil circuit loose
Control board relays that did not close

✓ One safe check you can try

1. End the cycle and wait for the heat to drop before doing anything else. 2. Let the control restart by cycling the breaker off and on. 3. Check whether 1F22 shows up on the next short run. 4. Should 1F22 appear again, stop using the oven and book a visit.

! Why to stop there

Two open paths in one circuit point to a shared cause, and finding it needs testing. The broil circuit carries high current too.
Replacing parts by guesswork gets expensive, so we confirm the cause before ordering anything.
The repair is protected by our 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.

1F221F22 questions

Why do I see 1F22?

Both DLBs for the lower broil element read as open, so the control cannot complete the circuit it needs to heat that element. Our technician starts from 1F22 on the screen, and then we outline the options.

Why would both DLBs open together with 1F22?

That suggests something they share, such as a connection or the control output. We test to find which instead of replacing parts at random. The meaning of 1F22 gets verified at your home, before any part gets ordered.

What still works with 1F22?

Other oven functions may carry on, but the lower broil will be weak or absent. If you have a double oven, the other cavity may keep working. Call us for a written quote.
