Amana AMVC960803BN Error Code EE2: Low Stage Pressure Switch Open
What Does Code EE2 Mean?
Error code EE2 on the Amana AMVC960803BN means the low-stage pressure switch circuit failed to close during the heating cycle. The inducer motor will run continuously, but the furnace will not proceed to ignition because it cannot verify that exhaust gases are venting safely.
The pressure switch is a safety device that confirms the inducer motor is creating enough negative pressure to properly vent combustion gases. It connects to the inducer housing via a small rubber hose. When the inducer runs and creates suction, the pressure switch closes, signaling the control board that it is safe to proceed with ignition.
If the pressure switch cannot close, common causes include a blocked or kinked pressure switch hose, a clogged flue or intake air pipe (ice, debris, or bird nests), a blocked condensate drain system preventing water from draining, a weak inducer motor that cannot create sufficient suction, or a faulty pressure switch itself. On this high-efficiency condensing furnace, a backed-up condensate drain is a particularly common culprit.
Common Causes
When to Call a Professional
Contact a licensed HVAC technician if:
- EE2 persists after clearing vents and the condensate drain
- The inducer motor sounds unusually loud, weak, or does not run at all
- The pressure switch hose and connections appear intact but the switch still does not close
- You see water leaking from the furnace or pooling around it
- The vent pipes appear to be properly installed but you suspect an internal blockage
