0130F00508 – FURNACE DUAL PRESSURE SWITCH (-0.55 PF & -0.30 PF)

If your furnace is short-cycling (turning on and off repeatedly), a failed pressure switch may be the cause. This is a dual pressure switch with two setpoints (-0.55″ and -0.30″ WC) — used on two-stage Goodman furnaces where the inducer runs at two different speeds.

Specs: Dual setpoints: -0.55″ WC and -0.30″ WC, two-port, OEM Goodman replacement

Replaces: 0130F00508

Fits: Goodman, Amana, and Janitrol two-stage gas furnaces

Fits these models

• Dual-stage pressure switch — fits 2-stage variable-fire residential gas furnaces (Goodman GMVC, Trane XV80, Carrier Performance 95, Rheem Prestige, Lennox EL296)
• Match BOTH pressure ratings to your existing dual switch — verify high-fire and low-fire ratings against your data plate
• Bring the old switch + furnace model number to the counter for verification

My furnace tries to start but never ignites -- is the pressure switch bad?

Maybe. Inducer pressure switches not closing are normally caused by one of four things: a bad switch, a bad inducer motor, a clogged flue vent, or a clogged hose between the switch and the inducer. Check the hose and vent first (free), then bench-test the switch and the inducer.

My furnace lights then shuts off after a few seconds -- could it be the pressure switch?

Almost never. That symptom is virtually always a dirty flame sensor -- the burner lights, but the sensor isn't pulling enough microamps to confirm flame, so the board closes the gas valve as a safety. Clean the flame sensor with fine emery cloth first.

What does -0.40PF mean?

That's the negative pressure rating: 0.40 inches of water column, "PF" indicates the trip direction (some are PR / 'pressure rising'). When inducer draft pulls the diaphragm down by 0.40" WC of vacuum, the switch closes the safety circuit. Match this rating EXACTLY -- wrong rating = nuisance trips OR no protection.

Can I jumper the pressure switch to make the furnace run?

NO. The switch is a safety device. Bypassing it can cause carbon monoxide buildup, vent gas spillage into the house, or fire. If yours is truly bad, replace it.

What's the difference between PF and PR ratings?

PF = pressure-falling, PR = pressure-rising. Some 2-stage furnaces use both styles on the same switch. The trip direction matters for how the board reads the safety circuit -- verify your existing switch's marking before swapping.

How long should a furnace pressure switch last?

10-20 years typical. Most failures come from water intrusion in the hose / port, not switch failure itself. Replace the silicone hose every time you service the inducer.
