A Goodman E3 error indicates the control board cannot verify the draft inducer is running. The most common fix is clearing debris from the pressure switch hoses or replacing a failing inducer motor capacitor.
When I show up to an E3 call, half the time it's a plugged pressure switch hose, and the other half it's a weak capacitor letting the inducer motor limp along at 80% speed. Ignore this and your furnace just won't start at all. When it's 20 below and you've got no heat, that's not a situation you want to sit on. Fix it now.

What Does the E3 Code Mean?
So your Goodman's flashing E3 and you've got no heat. Here's what's happening: the board's waiting for a signal from the pressure switch that says the inducer is up and running, and it's not getting it. Could be something as dumb as a clogged rubber hose or a $12 capacitor. Don't buy a new motor until you've ruled out both of those first.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Pressure switch hose blocked with condensate or debris40%
Inducer motor failure preventing the wheel from reaching speed24%
Control board not completing inducer startup sequence22%
Inducer wheel clogged reducing airflow14%
Symptoms You May Notice
You hear the inducer spin up for about 30-60 seconds and then everything shuts down before the burners ever light, then it tries again a few minutes later.
E3 is blinking on the board's LED display, or it's showing up in the fault history on a communicating thermostat.
House is getting colder and the furnace cycles constantly but never actually produces heat.
The inducer sounds totally normal but there's no click from the gas valve, no igniter glow, nothing happens after the motor runs.
On the coldest nights it might start once and run, then go into lockout on the second or third cycle when the condensate system gets overwhelmed.
Can you reset a Goodman furnace to clear the E3 code?
After your repair, flip the furnace toggle switch off, wait 30 seconds, then flip it back on. No toggle? Kill it at the breaker. The board runs its self-check automatically when power comes back. Watch the LED on the control board: normal cycling means you're good. If E3 comes back on the very first inducer startup, the underlying problem is still there and you need to dig deeper.

Frequently Asked Questions
What's the difference between E3 and 7P1 on a Goodman furnace?
They're related but different. E3 is a failure-to-prove fault, meaning the inducer's running but the pressure switch isn't closing to confirm it. On Goodman's newer communicating boards, 7P1 usually means the board doesn't see the motor at all, like there's a wiring issue or the motor's completely dead. In the field I treat them similarly at first: start with the vacuum hoses and capacitor, then work toward the motor and board from there.
Can condensate water in the pressure switch hose really cause E3?
Absolutely, and it's way more common than people think. These high-efficiency furnaces pull so much heat out of the combustion gases that they produce a ton of liquid condensate. If your drain lines are even slightly restricted, that water backs up into the inducer housing and gets pulled right into the pressure switch hose. If you find water in that hose, don't just shake it out and call it done. Check the whole condensate drain system including the trap, or it'll be back in a few days.
How long does a Goodman inducer motor last?
Usually 12 to 15 years, sometimes longer if it's in a clean environment with moderate run cycles. But the capacitor that runs the motor tends to go way sooner, often around 7-10 years. Honestly, if the motor's been in service more than 8 years and you're already in there for another reason, just swap the capacitor while you're at it. It's cheap. If the motor starts making a high-pitched screech or a heavy grinding vibration, the bearings are failing and replacement is coming whether you want it to or not.
How much does it cost to fix a Goodman E3 error?
Depends entirely on what's broken. If it's just a plugged hose, you're fixing it right now for free. A new run capacitor is $8-20 at the HVAC supply house and takes maybe 15 minutes to swap. A new inducer motor is where it gets expensive, usually $150-400 for the part depending on your model, plus labor if you're calling someone. Budget $300-600 total for a motor swap with a service call. GMVC96 and AMVC96 motors tend to run higher because of the ECM motor setup on those units.
Is it safe to keep running my furnace when it's showing E3?
No. The whole point of the E3 lockout is that the board can't confirm combustion gases are being properly vented before it opens the gas valve. If the furnace fired without a proven inducer, you could get flue gases backing into the living space. That's a carbon monoxide situation. Don't bypass the door switch, don't tape anything over a safety limit, don't mess with it. The board's doing exactly what it's supposed to do. Fix the actual problem, then let it run normally.
