How a Low-Fire Pressure Switch Works

Two-stage furnaces have multiple pressure switches to help the system to run at different speeds—and be more efficient. 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 Malfunctions

Your low pressure switch may not be functioning properly if your furnace inducer motor begins in high speed and high ignition, then weakens and changes into low-fire mode about 30 seconds afterward.

Your HVAC 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 reports a fault code.

Estimated Repair Cost for Furnace Error Code 229

A blocked vent or a draft can also trigger the error, so your Midland Air Service Experts Heating & Air Conditioning technician will investigate 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 repair it.

You can expect to pay between $40 and $350 if you need a new low-fire pressure switch.
