The Thermocouple on Your Laars Boiler

The thermocouple is a safety probe that senses the pilot flame and holds the pilot gas valve open. When it weakens, the gas valve closes and the pilot goes out — the most common cause of a pilot that will not stay lit.

On Laars systems — including models such as Mascot FT, Mascot HT, NeoTherm — a failing thermocouple often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Laars part.
