Carrier 340030-401 Compressor Plug with Temperature Sensor OEM HVAC Wiring Harness

The Carrier 340030-401 is a genuine OEM compressor plug with integrated temperature sensor, designed for use in Carrier heating, ventilation, and air conditioning (HVAC) systems. This factory-authorized replacement part ensures a precise, reliable connection at the compressor, allowing the system's control board to continuously monitor compressor operating temperatures and protect against thermal faults.

The built-in temperature sensor works in conjunction with the system's control circuitry to detect abnormal heat conditions at the compressor. When temperatures exceed safe thresholds, the sensor signal triggers protective shutdowns, helping to prevent costly compressor damage and extending the service life of the HVAC unit.
