Description
The Modine 3H0406290001 High Limit Switch is a genuine OEM replacement safety component engineered specifically for compatible Modine heating equipment. High limit switches play a critical role in protecting heating systems from dangerous overtemperature conditions — when supply air or heat exchanger temperatures exceed safe operating thresholds, the limit switch interrupts the burner circuit to prevent equipment damage, heat exchanger failure, and potential fire hazards.
