This part plays a critical role as your furnace prepares to heat your house.
Here’s what goes on after your thermostat’s call for heat:
When your pressure switch isn’t working correctly, you’ll likely hear the fan run and the switch clicking a few times before the furnace shuts down completely. When a part isn’t performing right, your furnace will turn off for your safety.
Your furnace will let you know something is wrong with a red flash from its indicator light, which it uses to display error codes. It uses this red light to flash code, like Morse code.
You may note fast flashes or an alternating slow flash as it communicates a fault code.
Before replacing the switch, your Comfort Masters Service Experts tech will look at other parts of your furnace first. Several other issues can also cause the error code, like a congested vent or cracked hose.
The price to repair your furnace depends on what’s wrong with it and how long it takes to fix it.
If your pressure switch needs to be replaced, you can expect to pay between $40 to $350.
If you need furnace repair, trust the technicians from Comfort Masters Service Experts to diagnose the fault code and fix the issue to your standards.
