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 |
|---|---|---|
| 1 Flash | Lockout after failed ignition attempts | Confirm the gas valve is open and power-cycle once; call a technician if it returns |
| 2 Flashes | Pressure switch stuck closed | Requires technician diagnosis |
| 3 Flashes | Pressure switch stuck open: vent, inducer or hose problem | Check outdoor vent pipes for snow or ice; otherwise call a technician |
| 4 Flashes | Open high-limit switch: overheating protection | Replace clogged air filter; check for blocked supply vents |
| 5 Flashes | Flame sensed with no call for heat: likely gas valve problem | Gas safety issue. Turn the furnace off and call a licensed technician immediately |
| Rapid Flash | Reversed line-voltage polarity | Wiring fault. Call a technician or electrician |

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). On common Goodman boards: 4 flashes = open high limit (change the filter), 1 flash = ignition lockout, 5 flashes = flame sensed with no call for heat (turn the furnace off and call us immediately). Codes vary by board, so check the chart on your furnace door.
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: replace the furnace if the repair costs more than about half the price of a new one, or if it is 15 or more years old and needs a major repair. At 12 years, most repairs are still worth doing. We'll give you a transparent comparison.
