Amana-Goodman SER2A05012S R-32 A2L Refrigerant Detection Sensor, 5 ft Lead

The Amana-Goodman SER2A05012S is an OEM R-32 (A2L) refrigerant detection sensor, also called a refrigerant leak sensor. It is made by Sensata for Daikin North America and comes with a 5-foot lead. It mounts in the sensor bracket at the drain pan. It continuously samples the cabinet air for R-32 concentration and reports to the air handler's A2L control board.

Key Features:

• OEM A2L refrigerant detection sensor for Goodman and Amana R-32 systems
• 5-foot lead. The longer 8-foot version is SER2A08012S
• Monitors R-32 refrigerant concentration in the cabinet air
• Signals the control board to start leak mitigation when refrigerant is detected
• Specified in factory documentation for AMST R-32 air handlers, Amana AWST R-32 air handlers, and 2 and 2.5 ton AMVT R-32 air handlers

This is the correct replacement when a factory sensor faults, is damaged during service, or leaves the air handler locked in leak mitigation mode.
