What E9 means on this model
The high stage draft did not prove on this platform. The control asked the inducer to move air for the second stage of gas heat, waited for the pressure switch to confirm it, and got nothing, so it closed the high stage gas valve. Low stage often keeps working, which is why this reads as weak or slow heat instead of a dead furnace.
Symptoms you will notice
- Weak heat, or heat only on the first stage
- Furnace runs but never reaches full capacity
- Code appears on a call for high stage heat
- Longer run time than the same house used to need
Common causes
The code tells you what the control detected, not which part failed. These are the causes we see most often, roughly in order of likelihood:
- High stage pressure switch or its tube fault
- Inducer motor not moving enough air on the high stage setting
- Blocked or restricted flue
- Failing inducer capacitor
- Control board high stage relay fault
What you can safely check
These are homeowner-level checks. None of them need you to open a live electrical compartment or work on gas.
- Set the thermostat to heat and listen for the inducer to start.
- Inspect the high stage pressure tube for cracks, kinks and water.
- Check the vent pipe outside for obstructions.
Do not do these
- ×Do not bypass the pressure switch.
- ×Do not run a furnace that will not reach full capacity as a permanent workaround. Low stage alone will not keep a cold house warm in a hard winter.
When to call a technician
Book a technician, do not keep resetting it
This fault will not clear on its own. Every power cycle gives the control one more failed attempt, and repeated attempts are what turn a cheap part replacement into a seized or contaminated system.
- This is a fuel-burning appliance, so treat anything involving a burner, gas valve or flue as technician work. If you smell gas at any point, leave the property and call the gas utility from outside rather than continuing to diagnose.
- If the appliance has stopped mid-cycle, is making a noise you have not heard before, or smells burnt, stop reading here and call. Those are symptoms of something the fault code does not describe well enough.
Tube inspection and vent checks are fine. A failed pressure switch or board is technician work.
What it costs to fix
Parts
Pressure switch $30 to $90. Inducer capacitor $15 to $40. Inducer motor $150 to $400.
Labor
One to two hours.
DIY or technician
Tube inspection and vent checks are fine. A failed pressure switch or board is technician work.
