The Thermocouple on Your Rheem 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 Rheem systems — including models such as Prestige, Classic, Classic Plus — a failing thermocouple often shows up as no hot water or related symptoms. We diagnose it precisely and install the correct genuine Rheem part.
