Lennox 31W67 Relay Sequencer 322027-701 or differential air pressure inThe Lennox 31W67 Relay Sequencer is a critical multi staged control component designed for electric furnace sequencer replacement and HVAC system timing management. This HVAC sequencer relay functions as a technical conductor, utilizing a stacked relay design to coordinate the activation of heating elements, blowers, and compressors in a precise sequence of operation. By staging electrical loads, the 31W67 prevents circuit overloads and nuisance
