Air Conditioner Thermostat

The basic phenomenon behind the working of air conditioner thermostat is random air current. If you study an air conditioner thermostat you will realize that it has bi metals and it is these bi metals or thermistor that sense the air current returning to the air ducts or the surrounding air. The thermostat of an air conditioner uses the room temperature to compare with the set point temperature. Here it must be noted that all HVAC thermostats will work on this principle irrespective of its type and model. As far as an air conditioner thermostat is considered it controls the air conditioner units. It is used to turn the heater or AC unit on or off.

Now a pertinent question that might come up is the way one should set the thermostat of an air conditioner. Here it must be noted that your air conditioner has two parts one that cools the air and the other is for moving the air. It is possible for you to adjust the part that cools the air by setting the thermostat accordingly while you can adjust the air movement by setting the fan to “ON” or “auto” mode. When the fan is set in “auto” mode the air conditioner moves the air only when the cooling part is running. When the thermostat senses that the room has reached the desired level of temperature it shuts off both the fan and the cooling. On the other hand, if the fan is in “ON” mode, the fan keeps on running even when the cooling part is turned off.

There is no denying the fact that one of the setting is better than the other. It is recommended that the fan should always be kept in “Auto” mode rather in “On” mode. There are several reasons for it. For example, in case you have an oversized AC it will shut off after a short while and will leave a lot of water in the coil. If the fan is continuously running the water will evaporate soon and will be thrown back to your home. Secondly, if you have leaky ducts outside the house a fan that is kept running continuously will add to the air leakage of the house.

Another important aspect related to thermostat is fixing the thermostat at home in case it is the trouble maker for your faulty air conditioner. Instead of calling the technician immediately you can try out some of the methods at home all by yourself.

First of all you need to check the thermostat if it is in “ON” position and also ascertain that it is set to AC or cool position.

Secondly, if you have old batteries you need to replace them with new ones and ensure that the thermostat has power.

After trying out all these tricks even then if your thermostat is not working rather your air conditioner does not start functioning it is important that you get in touch with a trained HVAC technician who will be able to detect the exact problem and take action accordingly.
