Trane CNT4364 Control Board Els PW 17895 Check for crack in the

Check for crack in the vacuum tubing or blockages in the flue before replacing the switch

this switch ensures reliable electrical continuity and minimal contact resistance in demanding mechanical environments

Dual Voltage Compatibility: Rated for 440V but is backwards compatible for 370V applications where space permits

replacing the sensor with this factory-tested HVAC high limit control restores system safety and prevents short-cycling issues caused by degraded bimetal sensors

effectively shedding precipitation and resisting humidity-induced signal noise

Trane CNT4364 Control Board Els PW 17895 Check for crack in theThe Trane CNT4364 Defrost Control Board serves as a critical OEM replacement component for high performance heat pump and packaged HVAC systems. This HVAC control module is engineered to monitor 24V AC signals and environmental conditions, managing the cycle between heating and defrost modes to prevent excessive ice accumulation on the outdoor coil. As the direct replacement for the legacy CNT2935 defrost board, the CNT4364 brings enhanced logic for
