Daikin-McQuay 349982403 Temp Sensor Assembly

The Daikin-McQuay 349982403 Temperature Sensor Assembly is a critical OEM replacement part designed for high-precision thermal monitoring in commercial and industrial HVACR systems. This NTC thermistor assembly features a 354-inch lead length, allowing for versatile placement within Daikin Applied and McQuay MicroTech III control architectures. Engineered with a durable ceramic sensor head, the 349982403 effectively translates ambient air or fluid temperatures into electrical signals for the main control board, facilitating real-time HVAC system monitoring and capacity modulation.

For veteran technicians, the Daikin 349982403 sensor is a standard integration for maintaining energy efficiency and precise discharge air temperature control. Its rugged construction enables reliable operation across a wide thermal range, typically 14°F to 115°F, ensuring stable climate control performance in demanding rooftop units (RTU) and chiller applications. Replacing a drifted or failed sensor with this genuine Daikin part prevents erroneous readings that lead to short-cycling or compressor hunting, directly extending the service life of the primary equipment while optimizing indoor air quality.
