The home’s thermostat is the primary control to the entire heating and cooling system. The thermostat is connected to a number of electrical systems and sensors to help direct and control the heating and cooling system. When the thermostat appears to be malfunctioning, the problem may not be the thermostat at all. It may be the temperature sensor. A thermostat may randomly turn off the cooling system, or heat or cool the home to the wrong temperatures. These are classic signs that the temperature sensor is faulty. Air Supply Heating & Air Conditioning will share how to better troubleshoot a faulty temperature sensor.
What is a Temperature Sensor & How Does it Work?
The thermostat uses a temperature sensor to detect the temperature of the air that is being cooled. The temperature sensor is located near the evaporator coils. The air that is sucked through the return vent passes over this sensor. The sensor will compare the temperature that is being sucked up to the temperature that is set on the thermostat. If the temperature is warmer than the temperature that is set on the thermostat, then the thermostat will trigger a cooling cycle. Once the sensor detects the proper temperature, it will than signal the thermostat to stop the cooling cycle. When there is a problem with the sensor the entire cooling system is compromised.
What Causes an AC Temp Sensor to Fail?
A number of different problem can occur with the temperature sensor. One may be the temperature sensor has become dislodged. If this happens, it will disrupt the on and off cycle of the air conditioner. Often this will result in the air conditioner prolonging or even trigger a constant cooling cycle. Another symptom of a dislodged temperature sensor is that the air conditioner will randomly switch on or off. To correct this problem an HVAC technician will need to check the position of the sensor. You need to be careful when re-positioning the sensor so make sure to seek professional assistance.
Why You Should Repair a Failing Temperature Sensor Right Away
When there is a problem with the temperature sensor you will not want to ignore this problem. It is a fast problem to correct and will not cost you much to restore. However, if you do not fix the temperature sensor the air conditioner will have erratic cycles that can add stress to the cooling system. Prolonged cooling cycles will add stress and wear down the air conditioner faster. Additionally, the prolonged if not constant cooling cycle will really hit your wallet. An air conditioning system consumes a lot of energy and you will see it on your power bill. To prevent additional wear and tear on your air conditioning system, and avoid an outrageous power bill, make sure to repair the temperature sensor quickly.
