Amana AMVM970803BN Error Code EE2: Low Stage Pressure Switch Not Closed
What Does Code EE2 Mean?
Code EE2 means the induced-draft blower is running but the low-stage pressure switch never closes to confirm proper draft, so the furnace cannot safely ignite. The inducer may run continuously with no burner operation.
The pressure switch closes only when the inducer pulls the correct vacuum. On this furnace, a blocked or pinched pressure-switch hose, a blocked flue or intake pipe, a clogged condensate drain, or a weak inducer can all prevent that vacuum from forming. A faulty switch is also possible.
EE2 is the low-stage version of EE9 (high-stage switch not closing). It is the opposite of EE1 (low-stage switch stuck closed at start). Because a blocked flue is a combustion-safety concern, EE2 is diagnosed and corrected by a professional rather than the homeowner.
What You'll Notice
- The inducer runs continuously but the burners never light, with EE2 displayed
- No heat despite a call, and the furnace never reaches ignition
- Possible signs of a blocked vent, such as ice or debris at the outdoor termination
- Water may be backing up if the condensate drain is clogged
Common Causes
How This Is Diagnosed
A technician inspects the pressure-switch hose for blockage, pinching, or improper connection, then checks the flue and intake piping for blockage, correct length, elbows, and termination, and verifies the condensate drain is clear. Inducer performance is checked to confirm it can pull adequate vacuum.
If the venting, drain, hose, and inducer are all good but the switch still will not close correctly, the pressure switch is replaced. Wiring is verified as well.
When to Call a Professional
This code involves components that are not homeowner-serviceable, so have a licensed HVAC technician diagnose and repair it. Keep in mind:
- The inducer runs but the furnace never ignites, with EE2 shown
- You see ice, snow, or debris blocking the flue or intake termination
- Water is backing up, suggesting a clogged condensate drain
- The code returns after any obvious vent obstruction is cleared
Frequently Asked Questions
Can a blocked vent cause EE2?
Yes — a blocked flue or intake pipe prevents the inducer from establishing the draft the low-stage pressure switch needs to close, which is one of the most common causes of EE2.
Is EE2 dangerous?
The furnace safely refuses to ignite, which is protective, but the underlying cause can involve venting or drainage that should be corrected promptly by a technician to restore safe heating.
