If you have line voltage and 24V signals but the motor only "rocks" or fails to spin

It is rated for approximately 0

which is critical for reducing mechanical vibration and preventing premature component wear

The intake-side hub location ensures the air flow is directed toward the motor

providing flexibility for various piping requirements

Heil Quaker ICP NASA401LA Kit mario If you have line voltageThe Heil Quaker ICP NASA401LA Low Ambient Kit is a field installed fan pressure switch assembly designed to maintain optimal head pressure during low outdoor temperature operations. Engineered for ICP HVAC equipment, this kit monitors the liquid line pressure to cycle the outdoor fan motor, preventing evaporator coil freeze up and ensuring consistent compressor lubrication when ambient temperatures drop below 55F. The NASA401LA pressure switch is
