Details for 18J74
Lennox 18J74 Low Ambient Pressure Switch Controls the operation of heating and cooling systems by monitoring the pressure in the system. When the pressure drops below a set point, the switch opens, turning off the system. This prevents damage to the system from low pressure conditions.
The 18J74 is a reliable and accurate switch that is easy to install and maintain. It is a critical component of any heating or cooling system and can help to prevent costly repairs.
