Carrier 11201011000187 CN26 to T3/T4/Tp Wire Harness for ICP HVAC Systems

The Carrier 11201011000187 is a genuine OEM replacement wire harness designed to connect the CN26 connector to the T3, T4, and Tp temperature sensor terminals in ICP, Comfortmaker, and Tempstar HVAC systems. This harness ensures reliable electrical continuity between the control board and critical temperature sensing circuits, maintaining accurate system monitoring and safe operation.

The T3, T4, and Tp designations correspond to key system sensors — typically the return air, outdoor ambient, and coil/pipe temperature sensors respectively — which the control board relies on to regulate heating and cooling cycles. A damaged or failed harness in this circuit can result in sensor faults, system lockouts, or incorrect temperature readings.

Key Features:

• Genuine OEM replacement part — exact fit and function for ICP family equipment
• Connects CN26 board-side connector to T3, T4, and Tp sensor terminals
• Maintains signal integrity for accurate temperature monitoring
