How a Low-Fire Pressure Switch Works
Two-stage furnaces have various pressure switches to help the system to run at different speeds—and use less energy. These switches also ensure your furnace runs safely and vents excess gases from the heat exchanger.
What Happens When a Low-Fire Pressure Switch Doesn’t Work
Your low pressure switch may not be operating right 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 furnace will demonstrate something’s not right with a red flash from its indicator light, which it uses to display error codes. It has this red light to flash code, like Morse code.
You may observe 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 create the error, so your Service Experts Heating & Air Conditioning professional will check other parts of your furnace first.
The bill to fix your furnace hinges on what’s wrong with it and how long it takes to repair it.
You can expect to pay between $40 and $350 if you require a new low-fire pressure switch.
