Furnace Pilot Light Repair in Portland, ME

A pilot light is a small standing flame that ignites your furnace's main burner when heat is called for. When it goes out or won't hold, your furnace simply won't fire. Most homeowners notice it first on a cold morning when the thermostat clicks but nothing happens. We find the root cause — whether that's a failing thermocouple, a dirty pilot orifice, or a gas supply issue — and fix it right.

Portland Furnace Repair Pros provides furnace pilot light repair for homeowners across Portland, ME. Call for a free inspection and a written quote before any work begins.

When to Call

When You Need Furnace Pilot Light Repair

  • Your pilot light goes out repeatedly during a cold Portland January snap
  • You relit the pilot yourself but the flame is weak and yellow, not blue
  • The furnace stopped firing after the gas was shut off for a repair
  • Your older Cape Elizabeth home has an original 1990s furnace with a standing pilot

How It Works

Our Process for Furnace Pilot Light Repair

  1. 1

    Visual Inspection

    We look at the pilot assembly, check the flame color and size, and confirm gas is reaching the pilot orifice.

  2. 2

    Thermocouple Test

    We measure the thermocouple's millivolt output. A weak reading tells us it can no longer hold the gas valve open.

  3. 3

    Clean or Replace Components

    We clear any debris from the pilot orifice and replace the thermocouple or thermopile if readings are outside spec.

  4. 4

    Confirm Stable Operation

    We cycle the furnace several times and watch the pilot hold through each burner ignition before we leave.

Portland Context

Why this matters in Portland

Portland's older housing stock — triple-deckers on Munjoy Hill, capes in Deering — still has a lot of standing-pilot furnaces running. We work on them regularly and keep common thermocouple sizes on the truck.

Straight Talk

About pricing & scope

Scope depends on whether just the thermocouple needs replacing or the pilot assembly itself is corroded and needs full replacement. Older furnaces sometimes have parts that are harder to source, which can affect turnaround time.
