this integrated furnace control regulates the ignition sequence

or a sticking potential relay are the primary causes

normally closed (NC) switch is factory-calibrated to open at 170°F

By delivering consistent feedback to the economizer or controller

it handles the intense thermal stress of localized pilot flames while maintaining consistent electrical resistance

Copeland 940-0001-79 Potential Relay Els PW 17895 this integrated furnace control regulatesThe Copeland 940 0001 79 Potential Relay is a mission critical component designed for high torque motor starting in commercial refrigeration and air conditioning systems. Engineered for precision, this 3ARR3KC3P5 potential relay monitors the back electromotive force (EMF) to efficiently disconnect the start capacitor once the compressor reaches optimal operating speed. This OEM Copeland replacement part ensures consistent compressor start up and
