0130F00506 – FURNACE PRESSURE SWITCH (-0.75PF)

Furnace air-proving pressure switch for Goodman/Amana gas furnaces, recorded at a -0.75 in. W.C. setpoint. It senses draft-inducer vacuum and closes to permit ignition, locking the furnace out if the vent, drain or inducer is restricted. Setpoints in this family differ by only hundredths of an inch of water column, so match the rating on the old switch exactly. Goodman/Daikin publishes no public part detail, so the specifications below come from our own stock records; confirm against the part nameplate before installing.

What does the furnace pressure switch prove?

It is a normally open switch on a hose running to the inducer housing or the heat exchanger. When the inducer spins up and pulls enough negative pressure, the contacts close and the board is allowed to light the burners. A switch marked -0.75 in. W.C. closes at three quarters of an inch of water column of vacuum. That is the furnace verifying draft before it makes fire.

Mine will not close. Do I need a new switch?

Usually not, because these do not fail all that often. On a 90 percent furnace look at the condensate trap and drain line first - water backing up into the secondary heat exchanger is the most common cause we hear about. After that, the hose (cracked, kinked, or full of crud and water), the port on the inducer housing, the flue and intake for a bird or wasp nest, and the inducer itself for weak amp draw or a chewed up wheel.

How do I pick the right one?

Read the setpoint off the switch body. It is printed or stamped right there, along with whether it is a single or two-stage switch. Do not guess by looks - the same housing gets built at a half dozen different pressures, and -0.75, -0.80 and -0.85 in. W.C. are indistinguishable on the shelf. Bring the old switch or a clear photo of the label.

Can I jump it out to get heat tonight?

No. That switch is what keeps a blocked flue from pushing combustion gas into the house instead of out the roof.
