On the covered Goodman gas furnace, EE2 means the low-stage pressure switch circuit is not closed, with the induced-draft blower running continuously and no furnace operation. Goodman lists a blocked, pinched or wrongly connected pressure-switch hose, a blocked flue or inlet air pipe, a blocked drain system or weak induced-draft blower, an incorrect set point or malfunctioning switch contacts, and loose wiring. First, look for anything blocking the flue and inlet air pipes outside, such as snow, ice, leaves or a nest.

Correct only the documented fault domain
ReversibleGoodman's corrective actions: inspect the pressure-switch hose and repair or replace it, inspect the flue for blockage, proper length, elbows and termination, check induced-draft blower performance and correct as necessary, check pressure-switch operation and replace as needed, and tighten or correct the wiring.
Inspect the pressure switch hose
ReversibleA cracked, pinched or water-filled hose is the most common reason the switch reads open. Remove it, blow through it and look for moisture or a blockage before replacing anything.
Check the flue, the intake and the drain
ReversibleA blocked vent or intake pipe, or a condensate drain that has backed up, changes the pressure the switch sees. Clear each and watch the inducer.
Watch the inducer motor
ReversibleA weak draft inducer cannot pull enough vacuum to close the switch. If it runs slowly or noisily, the inducer is the next suspect, for a technician.
Do not jumper the switch
ReversibleIt is tempting to bypass a pressure switch to get heat back, but the switch proves the exhaust is venting. A furnace running without that proof can put carbon monoxide into the house, so leave it to a technician.

Common questions about “Goodman gas furnace code EE2”
What does EE2 mean on a Goodman gas furnace?+
The low-stage pressure switch circuit is not closed, with the induced-draft blower running continuously and no furnace operation. Goodman lists a blocked, pinched or wrongly connected pressure-switch hose, a blocked flue or inlet air pipe, a blocked drain system or weak induced-draft blower, an incorrect set point or malfunctioning switch contacts, and loose wiring.
Can a bad pressure switch hose cause EE2?+
Yes, it is the first thing to check: a blocked, cracked or pinched hose or a water-logged drain tube gives the switch a false reading.
Why does EE2 show up mostly on cold days?+
Snow, ice or frost can block the outdoor flue and intake pipes, and condensation inside a cold pipe can freeze, so the draft the switch senses drops. Clearing the terminations safely from the ground often restores heat.
Will the furnace restart once I clear the blockage?+
Usually it retries ignition on its own after a short wait, and switching the furnace off at its service switch and back on forces a fresh start. If EE2 returns, stop and call a technician.
Is EE2 on a Goodman furnace dangerous?+
The furnace is protecting you: it will not fire without proof of draft. Do not bypass the switch, and have a technician check the vent if the code repeats.
How much does it cost to fix EE2?+
A cracked hose or a cleaned drain costs little; a failed inducer motor or pressure switch costs more. Start with the free checks of the hose, vent and drain.
