Amana AMVM970803BN Error Code EE2: Low Stage Pressure Switch Not Closed
What Does Code EE2 Mean?
Error code EE2 on the Amana AMVM970803BN indicates that the low stage pressure switch circuit is not closing during the ignition sequence. The induced draft blower is running, but the pressure switch is not detecting sufficient negative pressure to confirm safe venting. As a safety measure, the furnace will not open the gas valve or attempt ignition.
The pressure switch is a critical safety component that verifies the induced draft blower is creating enough draft to safely exhaust combustion gases. A small rubber hose connects the pressure switch to the inducer housing, and any disruption in this path can prevent the switch from closing. The switch must close before the control module will proceed with the ignition sequence.
The most common causes include a blocked or kinked pressure switch hose, a blocked flue or fresh air intake pipe (from ice, snow, debris, or animal nests), or a clogged condensate drain that backs water into the inducer housing. A weak or failing induced draft blower or a malfunctioning pressure switch itself are also possible but typically require professional diagnosis.
Common Causes
When to Call a Professional
Contact a licensed HVAC technician if:
- EE2 persists after clearing the flue, intake, and condensate drain
- The pressure switch hose appears damaged or the connections are deteriorated
- The induced draft blower sounds weak, rattles, or does not start at all
- Water is backing up in the inducer housing despite a clear drain
- You are not comfortable inspecting the pressure switch or internal components
