A limit switch is a safety device designed to shut down furnace equipment when temperatures exceed safe operating limits. When the air temperature reaches the preset threshold of 240°F, this switch trips and cuts power to the system. The manual reset button must be pressed to restore operation, alerting technicians to investigate the cause of overheating before resuming normal operation.

This part replaces earlier part number 10123539 and is compatible with numerous Goodman, Amana, and Janitrol furnace models. The "Orange (5)" designation refers to the color-coding system used by the manufacturer for temperature rating identification.
