How a Low-Fire Pressure Switch Works
Two-stage furnaces have multiple pressure switches to allow the system to run at different speeds—and be more efficient. These switches also guarantee your furnace runs safely and vents extraneous gases from the heat exchanger.
What Happens When a Low-Fire Pressure Switch Fails
Your low pressure switch may not be working properly if your furnace inducer motor starts up in high speed and high ignition, then loses speed and enters into low-fire mode about 30 seconds after.
Your system will indicates something’s amiss with a red flash from its indicator light, which it uses to exhibit error codes. It has this red light to flash code, like Morse code.
You may see fast flashes or an alternating slow flash as it tells you a fault code.
Estimated Repair Cost for Furnace Error Code 229
A blocked vent or a draft can also create the error, so your Rob's Albertan Service Experts technician will investigate other parts of your furnace first.
The price to fix your furnace relies on what’s wrong with it and how long it takes to fix it.
You can plan to pay between $40 and $350 if you require a new low-fire pressure switch.
