Troubleshooting your Broan downdraft ventilation system when the vent won't go up

First, check for electrical power going to the downdraft blower. Check the house circuit breaker; if it tripped, reset the breaker and see if the vent will go up. If not, check the electrical outlet to make sure it has power. Plug a small lamp or appliance into the outlet. If the outlet isn't working, have an electrician repair the electrical outlet.

If the outlet's okay, then you may need to adjust the position of the up/down activation switch. To check the switch position, unplug the downdraft vent, lift the vent and tilt it slightly so it stays in the raised position. Remove the switch cover from the right end of the vent. Check the position of the up/down activation switch plunger. If the plunger isn't touching the bottom of the vent's button membrane, loosen the up/down activation switch mounting screws and move the switch up until the button membrane barely touches the up/down activation switch plunger. Replace the switch cover and restore electrical power to the downdraft vent.

If the up/down activation switch position is okay, check the up/down button pad for damage. Replace the up/down button pad if it's not activating the up/down activation switch plunger when you press the button pad.

Common replacement parts for Broan downdraft ventilation systems

  • Gear motor. The gear motor raises and lowers the pop-up vent when you push the activation switch. Limit switches shut off the gear motor when the pop-up vent reaches its destination.
  • Grease filters. The grease filters are aluminum mesh filters that trap grease suspended in the exhaust. The grease filters attach at an angle inside the vent opening.
  • Limit switch. The limit switch detects the position of the pop-up vent and stops the gear motor from operating when the vent reaches the full up or down position.
  • Up/down switch. The up/down switch on the right side of the pop-up vent starts the gear motor to raise or lower the pop-up vent when pressed.
