Description
The York S1-024-35888-000 is an OEM replacement limit switch engineered to protect York furnaces and heating systems from dangerous overheating conditions. With a precisely calibrated open temperature of 235°F and an automatic reset point of 205°F, this limit switch reliably interrupts the burner circuit when supply air temperatures exceed safe operating thresholds — then automatically restores normal operation once temperatures return to the safe range.
How It Works
The limit switch continuously monitors heat exchanger or supply air temperatures. If the monitored temperature climbs to 235°F, the switch opens and shuts down the burner to prevent equipment damage and potential fire hazards. Once the temperature drops back to 205°F, the switch automatically resets, allowing the system to resume normal heating operation without manual intervention.
