How a Low-Fire Pressure Switch Works

Two-stage furnaces have numerous pressure switches to allow the system to run at different speeds—and be more efficient. These switches also make sure your furnace runs safely and vents extra gases from the heat exchanger.

What Happens When a Low-Fire Pressure Switch Doesn’t Work

Your low pressure switch may not be operating correctly 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 system will demonstrate something’s amiss 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 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 trigger the error, so your Service Experts Heating & Air ConditioningExpert will look at other parts of your furnace first.

The bill 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.
