The Hired Hand 3005-1311 High-Limit Switch is an old-style, surface-mount safety switch designed for use in Hired Hand Super Saver XL 225,000 BTU heaters. With a temperature rating of approximately 320°F, this switch protects the heater by shutting it down when internal temperatures rise beyond safe levels.
This model features a manual-reset design, meaning the switch must be physically reset after the heater cools and the cause of overheating—such as dirty filters, blocked airflow, or dust buildup—has been resolved. Consistent tripping often indicates that the heater needs cleaning or maintenance to restore proper airflow.
Replacing this high-limit switch helps maintain the heater’s safety functions, prevents internal damage, and supports reliable operation in demanding agricultural environments.
