Thermostat

 

The air conditioner thermostat regulates the air temperature to keep it within a set range. When the temperature goes above what the unit is set for, the thermostat actuates a switch to begin the cooling process. In order for cooling to take place, the compressor and fan motor must be switched on. If the thermostat is broken, it could be causing the fan motor and compressor to not switch off once the selected temperature is reached. To decide if your thermostat is the issue, turn your air conditioner on and test the continuity of the part using a multimeter.

Thermistor

 

The air conditioner thermistor is responsible for sensing the temperature of the air in the room. If the thermistor is defective, it could be taking inaccurate temperature readings. As a result, it could then be reporting the temperature as warmer than it actually is, causing the compressor to run continuously.

Temperature Control Thermostat

 

The air conditioner temperature control thermostat supplies the necessary amount of voltage to the compressor and the fan motor. If the control has shorted out, it may send ongoing voltage to these parts, causing them to keep running. Use a multimeter to decide if your control thermostat has continuity all the time; if it does, then it has shorted out.
