Signs You May Need a New Furnace Pressure Switch

The pressure switch is a safety device that confirms the inducer motor is pulling proper draft before allowing gas to flow. If it fails or can't close, the furnace won't ignite.

⛔Furnace Starts Inducer but Won't Ignite▼
  • The inducer motor runs but ignition never happens.
  • The pressure switch should close once draft is established — if it doesn't, the sequence stops.
  • Check the rubber hose connecting the switch to the inducer housing for cracks or blockages.

Before replacing the pressure switch, check: (1) Is the drain line clogged? (2) Is the inducer hose cracked? (3) Is the flue vent blocked? These are the most common causes.

🔴Pressure Switch Error Code on Control Board▼
  • The diagnostic LED shows a code indicating "pressure switch stuck open" or "stuck closed."
  • "Stuck open" means the switch never closes — check the inducer and hose first.
  • "Stuck closed" means the switch is welded shut and needs replacement.
🔄Intermittent Furnace Shutdowns▼
  • Furnace lights successfully sometimes but fails on other attempts.
  • A weak pressure switch may close intermittently depending on draft conditions.
  • Wind gusts or a partially blocked flue can cause inconsistent pressure readings.
