York S1-024-35619-000 Relay the S1-024-26099-000 furnace switch providesThe York S1 024 35619 000 is an essential 24V on break relay designed to provide reliable compressor short cycle protection. In the field, we see compressors fail prematurely when they try to restart against high head pressure; this HVAC time delay relay prevents that by enforcing a specific "off" interval after the thermostat call is satisfied. By allowing refrigerant pressures to equalize and oil to return to the sump, it significantly reduces the
