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 functioning 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 functioning right, your furnace will turn off as a safety precaution.
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 Fras-Air/General Service Experts tech will look at other parts of your furnace first. Several other issues can also cause the error code, like a clogged vent or cracked hose.
The price to remedy 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 should have furnace repair, trust the professionals from Fras-Air/General Service Experts to diagnose the fault code and fix the problem to your requirements.
