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 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 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 short flashes or an alternating slow flash as it communicates a fault code.
Before replacing the switch, your Rolf Griffin Service Experts 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 wrong with it and how long it takes to fix it.
If your pressure switch needs to be replaced, you can anticipate to pay between $40 to $350.
If you need furnace repair, trust the professionals from Rolf Griffin Service Experts to diagnose the fault code and fix the problem to your standards.
