Boiler Troubleshooting
Boiler Not Producing Heat — Diagnosis & Repair in Maine
A boiler that is not producing heat in winter needs prompt attention, particularly if the home is at risk of freezing. RG Mechanical evaluates oil, gas, and propane boiler problems in Central Maine, subject to equipment and scheduling availability.
What to Expect
Check thermostat is set correctly and has power
Check circuit breaker for the boiler
Oil-fired: check oil tank level and reset button on burner
Gas: confirm gas service is on and pilot is lit (older systems)
Failed circulator pump prevents heat from reaching baseboards
Call us immediately — we prioritize no-heat calls in winter
Frequently Asked Questions
Why isn't my boiler producing heat?
Common causes include ignition failure, oil supply issues, failed circulator pump, thermostat failure, tripped safety, or a controls fault. We'll diagnose the exact cause quickly.
My boiler is running but my baseboards stay cold. Why?
Usually a failed circulator pump or stuck zone valve. The boiler is heating water but it's not being circulated to your baseboards.
I pressed the reset button on my oil burner and it still won't start. Now what?
Press the reset button only once — multiple resets can flood the combustion chamber. Call us. This typically indicates a fuel delivery issue, ignition problem, or primary control failure.
How fast can you respond to a no-heat boiler call in winter?
Availability depends on weather, demand, location, equipment access, and parts. Call for the current schedule and mention any freezing risk, fuel odor, soot, or carbon-monoxide alarm.
