Quick Answer

An overheating boiler usually trips its high-limit and locks out. Common causes are a failed circulator pump, trapped air, sludge, a stuck valve, or a faulty thermistor/aquastat. Stop using it and call BoilerPart.ca for licensed repair across Greater Vancouver.

Boiler Overheating help for Coquitlam homes

Overheating is a protective shut-down: the boiler’s high-limit safety has detected dangerously hot water and cut the burner. The underlying cause must be fixed, never bypassed.

Our licensed technicians cover every Coquitlam neighbourhood — including Austin Heights, Maillardville, Burke Mountain, Westwood Plateau, Ranch Park, Harbour Chines — with genuine OEM parts and a workmanship guarantee.

What you’re noticing

  • Boiler locks out on overheat
  • Very hot pipes then sudden shut-down
  • Repeated high-temperature trips
  • Kettling/banging before lockout

Common causes

  • Poor circulation — failed pump, air or sludge
  • Stuck valve restricting flow
  • Scaled heat exchanger
  • Faulty thermistor / aquastat
  • Faulty high-limit control

What you can safely check first

Beyond these safe checks, do not open the boiler or touch gas, electrical or sealed components — BC law requires a licensed gas fitter. Call us for a proper diagnosis.

Stop using the boiler if it keeps overheating
Check whether radiators circulate at all
Confirm pressure is normal
Note any error code

When this is urgent in Coquitlam
