Weil McLain 540-130-968 Electrical Assembly with Harness for EGH 85–125 PI Boilers
The Weil McLain 540-130-968 is a factory OEM electrical assembly designed specifically for Weil McLain EGH Series 85–125 Power Ignition (PI) gas-fired boilers. This assembly integrates a pre-wired harness with a probe-type Low Water Cut-Off (LWCO-P), delivering a precision-engineered replacement that restores original equipment performance and maintains critical boiler safety functions.
The integrated probe-type LWCO is a vital safety component that monitors boiler water level and shuts down burner operation if water drops below a safe threshold — protecting the heat exchanger from dry-fire damage and extending boiler service life. As a direct OEM replacement, this assembly ensures proper fit, function, and compatibility with your existing EGH boiler controls without field modification.
