Reduced Mechanical Wear: Precision-machined ball joints minimize friction and eliminate "slop" in the linkage

This NTC thermistor is designed to provide precise resistance feedback to the system controller

Robust Construction: Housed within a protective box to safeguard sensitive SPDT switch components from debris and mechanical damage

a licensed HVACR technician should perform the replacement to ensure all safety interlocks are functioning correctly
