Wolf Downdraft All LEDs Flashing: Vent Will Not Rise or Lower

What All control LEDs flashing, does not move means

On Wolf downdraft vents with a 14-inch rise, such as the DD30, DD36, and DD45, all control LEDs flashing while the vent does not move points to the lift system. The official causes include an open safety or filter switch, a travel time-out of about two minutes, both limit switches reading open, a blown fuse FU1 or FU2, an actuator board, or an over-current condition.

Common causes of All control LEDs flashing, does not move

Safety or filter switch open
Travel time-out after about two minutes, or both limit switches open
Fuse FU1 or FU2 open
Actuator board or over-current condition

✓ One safe check you can try

1. Make sure nothing sits in the vent path and the grease filter is fully seated. 2. Clear any items from around the raised or lowered unit. 3. Turn the control off, wait a minute, then try again. 4. Do not force the vent by hand. 5. If it still will not move, call us.

! Why to stop there

Fuses, switches, and the actuator are inside the unit under the counter and carry line voltage.
Forcing a stuck downdraft can bend the lift and make the repair larger.
We trace the lift circuit, quote in writing first, and give 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.

All control LEDs flashing, does not moveAll control LEDs flashing, does not move questions

Why are all the LEDs flashing?

The vent is warning that it cannot complete its move. Causes include an open safety or filter switch, a travel time-out, open limit switches, a blown fuse, or an actuator or over-current issue.

Can I raise the downdraft by hand?

We advise against it. Pushing a stuck lift can bend parts and make a fixable issue worse. If it is in the way, call us and we will advise the safest next step.

What do you check first?

We start with the switches and filter position, then the limit switches, fuses FU1 and FU2, and the actuator board. The price is quoted in writing before work begins.
