a faulty pressure switch often fails to close the circuit to the control board

or a burnt coil that fails to pull in the armature when 24V is applied from the thermostat

The Conbraco 25-501-03 Water Gauge set is a heavy-duty boiler sight glass valve engineered for critical liquid level monitoring in high-pressure steam and hydronic systems

making it a preferred HVAC burner part for technicians requiring a versatile oil burner transformer

the 100074672 is strictly designed for Natural Gas (NG) configurations

Lochinvar & A.O. Smith 100108268 Thermocouple 321142-301 a faulty pressure switch oftenThe Lochinvar & A. O. Smith 100108268 Thermocouple is a critical safety component designed for precise flame rectification in commercial and residential water heating systems. This 24 inch thermocouple provides the necessary millivolt signal to the gas valve, ensuring the pilot flame is established before allowing the main burner to cycle. Engineered for high temperature environments, it is a direct replacement for various Lochinvar pilot assemblies
