Napoleon gas furnace showing code 2 Flashes on the 9500/9600/9700/NPGF Series? The combustion air (inducer/exhauster) blower is running but the pressure switch did not close, indicating insufficient draft/venting or a pressure-switch problem. Here is what it means, what you can safely check, and when to call a licensed CANRO technician in an urgent situation across Metro Vancouver.

What does Napoleon code 2 Flashes mean?
The combustion air (inducer/exhauster) blower is running but the pressure switch did not close, indicating insufficient draft/venting or a pressure-switch problem. This is an urgent fault that usually leaves you without heat or cooling — do not keep resetting it.

Likely causes of Napoleon code 2 Flashes

  • Blocked or restricted vent / exhaust pipe
  • Blocked condensate drain causing trap blockage
  • Disconnected or cracked pressure-switch hose
  • Weak or failed inducer/exhauster motor
  • Failed pressure switch

What you can safely check first

  • Check that the outdoor vent/intake termination is clear of snow, ice, leaves, or debris
  • Listen to confirm the inducer/draft motor is running on a call for heat
  • Cycle furnace power off and on to retry

What not to touch: beyond these checks, do not open the unit or touch the gas valve, wiring, control board or refrigerant lines. In BC, gas and HVAC repairs must be done by a licensed technician — both for your safety and to keep your manufacturer warranty valid.

⚠ Emergency signs: no heat in cold weather, a burning or gas smell, a tripping breaker, water around the unit, or a carbon-monoxide alarm. If you smell gas or a CO alarm sounds, leave and call FortisBC 1-800-663-9911 (and 911 if anyone is unwell) first — then call us for priority after-hours service.

Frequently asked questions

How often should a furnace be serviced?
Annual servicing is recommended for gas furnaces, ideally before the start of the heating season in September or October. Service includes burner cleaning, heat exchanger inspection, ignition check, blower motor cleaning, gas pressure adjustment and a full safety test for carbon-monoxide leaks.
How long does a furnace last in Vancouver's climate?
High-efficiency gas furnaces typically last 15–20 years with annual maintenance. Vancouver's mild climate means lower run-times than colder Canadian cities, which extends life — but salt-air corrosion near the coast and high humidity can shorten it.
Why is my furnace blowing cold air?
Common causes are a thermostat set to "on" instead of "auto", a tripped flame sensor, a clogged condensate drain shutting down a high-efficiency unit, low gas pressure, or a failed ignitor. Most are repairable in a single service visit.
How much does a new furnace cost in Vancouver?
A typical residential high-efficiency gas furnace in Metro Vancouver costs $4,500–$8,500 installed depending on size, brand and venting requirements. Variable-speed and modulating models are at the upper end.
What is the most reliable furnace brand?
In our experience servicing Vancouver homes since 1999, Carrier, Lennox, Bryant and York have produced the most reliable mid-to-high-efficiency furnaces with the best parts availability. Goodman and Rheem offer strong value at lower price points.
