The durable construction minimizes the risk of leaks at the gauge glass connection points

while wiring a 115V unit to this voltage will result in immediate winding burnout

this unit monitors the actual current draw through the run winding to manage the start circuit

check the 24V or PWM control signal from the furnace board to determine if the module or the board is at fault

Carrier HH79NZ039 Sensor 319848-301 The durable construction minimizes theThe Carrier HH79NZ039 is a Factory Authorized Part designed for high accuracy thermal monitoring in commercial and residential HVAC systems.
