Description
The Reznor RZ123974 Fan Limit Switch with Bracket 13530F controls fan operation and temperature limits within HVAC systems. It operates across a temperature range from 30F to 135F, cycling the blower on and off based on heat levels while also providing high-limit protection. Installed in furnaces or unit heaters, it monitors internal air temperature and responds through its mechanical switching mechanism without requiring complex electronics. This component plays a key role in regulating airflow timing and preventing overheating within the overall assembly.
