Maintain the thermal monitoring and operational precision of your indoor unit with the Samsung Air Conditioner Thermistor Assembly DB95-01945A. This specialized sensor array is a critical feedback component for the indoor unit's main PCB, typically consisting of two distinct sensors: the Room Temperature (Ambient) sensor and the Copper Pipe (Evaporator) sensor. Together, they monitor the incoming air temperature and the state of the refrigerant within the coils. This data allows the system to prevent the evaporator from icing up and ensures the compressor modulates correctly to maintain your desired comfort level. If your unit is displaying an indoor thermistor error code or if the fan runs without the compressor engaging, this assembly is often the component that has failed.

The DB95-01945A is engineered with high-accuracy thermal components protected by moisture-resistant resin and copper housings. The assembly includes a precision-molded multi-pin connector and a high-grade wiring harness designed to withstand the humid conditions inside the air handler without signal degradation.

Installation / Replacement Instructions

1. Safety First: Turn off the air conditioner and disconnect the power supply at the main circuit breaker.
2. Access the Internals: Lift the front intake grille and remove the air filters. You will likely need to remove the main front panel housing to access the control box and the evaporator coil.
3. Locate the Sensors:
The Ambient Sensor (usually with a plastic head) is clipped to the front of the evaporator coil.
The Pipe Sensor (usually with a copper head) is inserted into a metal sleeve or clipped directly onto a copper return bend of the evaporator coil.
4. Access the Control Box: Open the plastic or metal cover of the electronic control box located on the right side of the unit.
5. Disconnect the Old Assembly: Trace the bundled harness back to the main PCB and unplug the connector. Note the exact routing of the wires to avoid interference with the louver motor or fan.
6. Install the New Assembly: Plug the new DB95-01945A into the PCB. Route the wires along the original path and secure each sensor head into its designated location. Ensure the pipe sensor is seated firmly against the copper to get an accurate reading.
7. Reassemble and Test: Replace the control box cover and the unit's front housing. Restore power and monitor the unit. The system should now correctly sense the temperatures and operate without triggering diagnostic error codes.

Compatible with select Samsung split-system indoor units, this OEM-quality thermistor assembly restores the precise thermal feedback and protective logic originally designed for your system.
