This part plays a critical role as your furnace prepares to heat your home.
Here’s what happens after your thermostat’s call for heat:
When your pressure switch isn’t working correctly, you’ll likely hear the fan start and the switch clicking a few times before the furnace shuts down completely. When a part isn’t working right, your furnace will turn off to protect you.
Your furnace will let you know something is amiss 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 see quick flashes or an alternating slow flash as it communicates a fault code.
Before replacing the switch, your Levy & Son Service Experts tech will investigate other parts of your furnace first. Several other issues can also cause the error code, like a blocked vent or cracked hose.
The price to fix your furnace depends on the issue with it and how long it takes to fix it.
If your pressure switch needs to be replaced, you can plan to pay between $40 to $350.
If you need furnace repair, trust the technicians from Levy & Son Service Experts to diagnose the fault code and fix the problem to your standards.
