and LGB Series 1 boilers

Key Benefits: Precision Control: High-tolerance 4-8 psi range ensures accurate response to pneumatic signals for stable temperature regulation

provided the inductive full-load amperage (FLA) does not exceed 30 amps and the control system utilizes a 24V transformer

reducing the risk of delayed ignition or uneven flame patterns

The coil is spec'd at 420 Ohms DC resistance with a low 42 mA draw

Nordyne 626429R Limit Switch and LGB Series 1 boilersThe Nordyne 626429R Limit Switch is a critical safety component designed for precise thermal regulation in HVAC systems including electric furnaces and heat pumps. Engineered as a direct replacement for part 626429, this auto reset limit switch features an operating range of 120F to 170F. As a limit open on rise control, it utilizes a 1 pole configuration to interrupt the heating circuit when temperatures exceed the preset 170F limit, preventing heat
