Carrier 32LT660003 Solid State Head Pressure Control

Carrier 32LT660003 Solid State Head Pressure Control is a Motormaster solid-state accessory designed to modulate the condenser fan speed on Carrier cooling equipment in order to maintain proper head pressure. It is a field-installed control that belongs to Carrier's Motormaster head pressure family, alongside models such as 32LT900610 Motor Master solid-state head pressure control. The device uses solid-state regulation to adjust outdoor-fan motor speed in response to condenser head pressure, helping stabilize pressures and improve compressor operation under varying ambient conditions. Typical applications include Carrier HVAC installations that require precise head pressure management, such as rooftop and packaged systems in commercial environments.
