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 excess 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 begins in high speed and high ignition, then loses speed and shifts into low-fire mode about 30 seconds after.

Your system will demonstrate something’s not right 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 create the error, so your Service Experts Heating & Air ConditioningExpert will check other parts of your furnace first.

The price to fix your furnace hinges on what’s wrong with it and how long it takes to repair it.
