Thermistor
Part #5304471276
The thermistor on your home air conditioning unit monitors the room temperature. If you discover that your air conditioner is malfunctioning, or will not maintain a consistent temperature, you may have to replace the sensor. This part is black in color. The sensor is located in the interior of your air conditioner so you will need to open it up to access it. Make sure you disconnect the power source from the air conditioner before you begin this repair. This is an OEM part sourced directly from the manufacturer. This part is sold individually.

James - For model number LRA257ST20
May 18, 2023
Question is you put the front cover on with it plugged in and it will not start
Chris Boyle Profile
Hi James, thank you for your question. We have researched the model and would suggest checking the control board, part number PS8689739, for continuity using a multimeter. It controls most of the functions of the air conditioner including the starting and cooling. We hope this information helps!

Mindy - For model number LRA257ST20
May 15, 2023
Control panel no longer works on unit. No lights, no anything. Stuck on high and does not automatically shut off. Cools fine. Have to use the button on the plug to turn on and off. What part/parts do you think needs to be replaced? Thanks!
Chris Boyle Profile
Hello Mindy, thank you for your query. Based on the description that you have provided, we would recommend checking the user interface control board, part number PS2582890, to fix the issue. It displays the selections chosen for operation, such as fan speed and operation mode. We hope this helps, good luck with this repair!
