Trane RES0172 5100-Ohm Resistor

The Trane RES0172 Resistor is a fixed electrical component that provides a precise resistance value of 5100 ohms in control and sensing circuits. In HVAC systems, it is used on control boards and input signal paths to regulate voltage levels, condition sensor feedback, or define operating logic for electronic control modules. It is typically mounted directly on or near the main control board inside air handlers, rooftop units or condensing equipment. The resistor ensure accurate signal interpretation between sensors and the control system, supporting stable communication and correct operation of electrical control module.
