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 working right if your furnace inducer motor starts up in high speed and high ignition, then slows down and enters into low-fire mode about 30 seconds later.

Your HVAC will communicate 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 notice 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 Conditioning Expert will investigate other parts of your furnace first.

The cost 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 need a new low-fire pressure switch.
