The vacuum switch is located inside the mechanical area of the appliance and will have a black or reddish-orange hose attached. This switch closes the feed circuit when negative pressure above .05" WC is present in the firebox. This pressure switch is a safety device to shut off the feed motor if the exhaust or the heat exchanger system is excessively dirty, the venting is obstructed, or if the firebox door is not fully closed and properly sealed.

This is the newest style switch and replaces all previous vacuum switches.

This pressure switch does not come with a hose. If you need the switch and the hose you want part, SRV240-0450

We also sell the hose and switch together part, SRV7000-531-AMP-WH

  1. The hose connection for the vacuum switch, where it connects to the feed tube can sometimes get clogged with pellet dust. Use a paper clip to clear the blockage.
  2. The pellet hopper must have at least a pound of pellets in the hopper to create a seal around the base of the hopper for the switch to close
  3. Check snap disc #2 and make sure it is not tripped if your stove uses 3 snap discs for safety controls
  4. The combustion/ exhaust blower must be turning to create air flow to close the vacuum switch
  5. If your hopper has a hopper lid sensor, the hopper lid must be closed for the circuit to operate.
  6. Using a jumper wire to bypass the vacuum switch, if the stove operates and everything above has been checked, replace the vacuum switch.
  7. If the stove still does not operate with the vacuum switch bypassed, check all of the other safety switches in the feed circuit inluding testing the motor for proper operation.

  • The switch I have now is the 812-3430 but it has 2 wires connected to it, I don’t see that on this one? Also it says no hose, so I just use the hose I have now, kind of crazy questions I know.

    There are two spade connectors on the black side that you will reconnect the wires that you  took off of your old vacuum switch. If the vacuum hose that you have currently is in good condition, then go ahead and reuse it. There is no need to order the kit with the vacuum hose.
