How a Low-Fire Pressure Switch Works
Two-stage furnaces have various pressure switches to allow the system to run at different speeds—and work more efficiently. These switches also make sure your furnace runs safely and vents extraneous gases from the heat exchanger.
What Happens When a Low-Fire Pressure Switch Doesn’t Work
Your low pressure switch may not be functioning properly if your furnace inducer motor switches on in high speed and high ignition, then loses speed and enters into low-fire mode about 30 seconds later.
Your HVAC will communicate 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 announces a fault code.
Estimated Repair Cost for Furnace Error Code 229
A blocked vent or a draft can also generate the error, so your Norrell Service Expertstechnician will check other parts of your furnace first.
The price to fix your furnace depends 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.
