LENNOX 18M62 Corporation PRESSURE SWITCH

PRESSURE SWITCH

Pressure Switch 18M62 features standard design for replacement applications for Lennox and other brand furnaces, for furnace burner flame out protection.

The Lenox 18M62 Pressure Switch is made to fit Lennox HVAC systems and contain piezo ignition for gas-fired furnace systems.

Lennox pressure switches supplement airflow control to ensure proper air volumes and pressures are maintained on multi-system furnaces and heat pumps. Pressure switch is UL/CSA listed and tested for use with the Lennox Variable Air Volume (VAV) System.

Designed to sense the operating pressure of Lennox or compatible heating and cooling units, this self-adjusting pressure switch will reset the high pressure switch on cold start applications of some heat pumps. The high limit switch ensures a longer compressor life by monitoring the pressure ratio.

The 18M62 is a direct replacement pressure switch to control Lennox® Energy Recovery HVAC units providing superior temperature stability and control of reheat, system lockout, and minimum on/off requirements.

A pressure switch is a vital part of any furnace, which turns the unit on and off based on current need. This pressue switch by Lennox is designed to turn your furnace on when it reaches freezing temperatures, and off when the furnace is no longer needed. The 18M62 model can be utilized for a variety of different Lennox furnaces.

This switch is designed for use on Refrigeration Condensing Units, to monitor and control the High Side pressure. It may be used with ANY refrigerant, provided care is taken to verify correct leads for the application. The switch is factory preset for 75 PSIG (5.2 BAR) operation at 68°F (-20+/0C).
