This part plays a prominent role as your furnace prepares to work in your home.
Here’s what occurs after your thermostat’s call for heat:
When your pressure switch isn’t working correctly, you’ll likely hear the fan going 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 as a safety precaution.
Your furnace will let you know something is incorrect 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 A-Plus tech will check 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 repair your furnace depends on what’s defective 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 professionals from A-Plus to diagnose the fault code and fix the situation to your satisfaction.
