The Genuine Thermo King Ungraded Temperature Sensor Kit (Part Number: 40-0975 / 400975) is a highly sensitive electronic diagnostics core component engineered for commercial transport refrigeration systems. Tasked with continuously tracking internal environmental metrics, this premium "ungraded" thermometer lead measures return air, discharge air, and evaporator core temperatures. It relays real-time thermal telemetry data directly back to the smart control microprocessor board. Manufactured under strict OEM design baselines, the hermetically sealed casing blocks corrosive moisture entry and chemical road spray exposures. Swapping out a failed, shorted, or drifting factory thermistor eliminates inaccurate reading spikes, prevents false defrost lockouts, and keeps refrigeration cycles running at precise cargo temperature parameters.

⭐ Key Features & Benefits
  • Genuine Thermo King OEM Part: Delivers factory-calibrated voltage signals to ensure total system processing stability over generic imports. [1]
  • "Ungraded" Multi-Point Architecture: Engineered to function seamlessly across return air, discharge line, or evaporator tracking arrays. [1, 2]
  • Hermetic Moisture Barriers: Industrial-grade exterior sleeve insulates sensitive wiring matrix joints against melting moisture or sub-zero frost cycles.
  • Broad Temperature Range Accuracy: Translates subtle climate shifts inside the trailer box to guarantee cargo load protection.
  • Direct-Fit Wire Configuration: Features a pre-terminated connection block to eliminate unapproved field wire splicing or cutting loops.
🔧 Uses / Applications
  • Trailer & Truck Refrigeration Servicing: Universal replacement diagnostic hardware for Thermo King SB, SL, SLX, TS, and Spectrum series reefer trailer lines.
  • T-Series Nosemount Maintenance: Direct-fit application core matching T-600R, T-800R, T-1000R, and T-1200R high-capacity truck platforms.
  • Defrost & Microprocessor Fixes: Solves recurring control board fault codes regarding open or shorted sensor circuits.
  • High-Margin Liquidator Sourcing: Essential high-turnover mechanical item ideal for commercial truck fleets, mobile reefer mechanics, and long-haul food-logistics hubs. [1, 2]
