The RHEEM TSNA-ODULIQ is a condenser coil liquid temperature sensor designed for use in refrigerant-based cooling systems. This sensor monitors liquid-line temperatures at the condenser coil, providing real-time data to the system control board to support proper system operation and protection. It is a direct OEM replacement part intended for installation by licensed HVAC technicians servicing RHEEM equipment. The sensor integrates into the system wiring harness and communicates coil temperature readings that influence defrost cycles, compressor staging, or fault detection depending on the control board configuration.
This sensor is typically installed in residential or light commercial air conditioning and heat pump systems where liquid-line coil temperature monitoring is part of the system's control strategy. It is suited for outdoor condensing unit applications and is sold as an individual unit. Technicians replacing a failed or out-of-range sensor during a diagnostic service call will find this a straightforward OEM-style swap.
Designed as an OEM-style replacement temperature sensor for RHEEM refrigerant-based condensing units requiring a condenser coil liquid temperature sensor.
Installation should be performed by a licensed HVAC technician. Disconnect power to the condensing unit at the disconnect box before handling any electrical components or sensor wiring. Ensure the system is de-energized and allow capacitors to discharge before beginning work. Follow applicable local codes and manufacturer wiring diagrams when reconnecting the sensor to the control board.
