A modern furnace runs a strict startup sequence, and knowing where the sequence breaks is most of the diagnosis. The thermostat calls, the inducer motor spins up to prove draft through a pressure switch, the hot surface igniter glows, the gas valve opens, the burners light, the flame sensor confirms fire, and only then does the blower deliver heat to the house. In East Providence, RI, the failures cluster at predictable points: an oxide-coated flame sensor, a hot surface igniter cracked from years of thermal cycling, a pressure switch that will not close because the inducer is weak or the condensate trap on a high-efficiency model has clogged, or a control board with a burned relay. Each one stops the sequence cold, and each one mimics the others from the hallway.

When to Call for Furnace Repair in East Providence
Catching these issues early helps you avoid costly problems. Keep an eye out for the following clues:
- A fan that keeps running while the registers blow cool air
- A furnace that shuts off every few minutes before the house warms up
- Water, rust stains, or black soot around the flue or cabinet
- Yellow, wavering burner flames where they should be sharp blue
- A bang or boom when the burners ignite late
- Burners light, run a few seconds, then shut down repeatedly
- Clicking and a glowing igniter with no burner flame
- Grinding or high-pitched squeals from the blower
