Goodman Furnace Error Codes: Diagnostic Guide
Goodman furnaces communicate faults via LED flash codes on the control board. Here's what each code means and when to call us.
| Flash Code | Meaning | Typical Fix |
|---|---|---|
| E01 / 1 Flash | Ignition failure - gas valve or igniter issue | Clean or replace igniter; check gas supply valve is open |
| E02 / 2 Flashes | Pressure switch fault - inducer or flue blockage | Check exhaust vent for obstruction; inspect inducer motor |
| E03 / 3 Flashes | Limit switch tripped - overheating protection | Replace clogged air filter; check for blocked supply vents |
| E04 / 4 Flashes | Rollout switch tripped - flame escaping combustion chamber | Requires immediate professional inspection - do not reset without diagnosis |
| E05 / 5 Flashes | Flame sensor fault - burner not detected after ignition | Clean flame sensor rod with fine steel wool; check gas pressure |
| E06 / 6 Flashes | Low flame signal or flame sensor failure | Inspect flame sensor; verify gas manifold pressure |

Goodman Furnace FAQs
How long do Goodman furnaces typically last?
A well-maintained Goodman furnace typically lasts 15–20 years. Models from 2010–2015 with heat exchanger issues may fail earlier. We'll give you an honest assessment of repair vs. replacement.
Is Goodman a good furnace brand?
Goodman is a mid-range brand owned by Daikin - one of the world's largest HVAC manufacturers. Their current GMVM97 and GMEC96 series are solid units with good efficiency. Older models (pre-2012) had heat exchanger recalls you should know about.
My Goodman furnace is flashing an error code - what do I do?
Count the number of LED flashes (or read the display if your model has one). Common codes: 3 flashes = overheating (change filter), 5 flashes = flame sensor (needs cleaning), 4 flashes = rollout switch (call us immediately).
Does EcoFrost service Goodman furnaces in Mississauga and Toronto?
Yes - we repair and maintain all Goodman and Daikin furnace models across Mississauga, Toronto, Brampton, Vaughan, and the full GTA. Same-day service available.
My Goodman furnace is 12 years old and needs a repair - should I fix it or replace it?
The general rule: if the repair cost is more than 50% of replacement cost AND the unit is over 12–15 years old, replacement makes more financial sense. We'll give you a transparent comparison.
