Goodman E2 Error Code: Low-stage pressure switch circuit open
Updated October 2026 · Sourced from Goodman documentation
The low-stage pressure switch circuit is not closing. The manual lists a blocked or pinched pressure switch hose, a blocked flue or inlet air pipe, a blocked drain system or a weak induced draft blower.
Is it safe to keep running? No. Turn it off and get it checked. Call a licensed technician. Flue, intake, pressure switch and inducer problems are combustion safety issues and need a professional.

Check this first
Only steps a homeowner can do safely. Do not open electrical panels or the burner area.
- Look outside at the furnace vent and intake pipe ends. Make sure snow, leaves or a nest are not blocking them. Look only, do not touch the pipes.
- Look at the condensate drain line and trap (if you can see it without removing any panel) for a clog, kink or standing water.
- Turn the furnace power off at the switch or breaker, wait one minute, then turn it back on to see whether the code returns.
🛑 Stop and call a licensed pro if
- Call a licensed technician. Flue, intake, pressure switch and inducer problems are combustion safety issues and need a professional.
- You smell gas. Leave the house, do not touch switches, and call your gas utility from outside.
- Flame rollout, limit or pressure switch codes that come back after one reset.
- Anything involving the control board, gas valve, flame sensor, igniter or venting.
- A carbon monoxide alarm sounds. Get everyone outside and call 911 or the fire department.
Safe first steps for any Goodman code
- Count the LED flashes through the blower door window before you switch anything off. Cutting power can clear the code.
- Replace or clean the furnace air filter.
- Check the thermostat: correct mode, set above room temperature, and fresh batteries.
- Make sure the furnace power switch and breaker are on. If the furnace has locked out, turning the power off and back on once restarts it.
- Make sure the gas valve is in the ON position, following the lighting instructions on the furnace label only.
- On high-efficiency furnaces, look at the outside vent and intake pipes for snow, ice, leaves or nests (look only, do not take pipes apart).
