When you turn on your Media air conditioning system, you assume that it will maintain the right temperature in every room of your home. A while it is easy to enjoy the cool air without understanding how your air conditioner works, understanding its basic functions can help you find the source of the problem if something goes wrong. An important component of your air conditioning system that you should be aware of is the limit switch.
What Is a Limit Switch?
Many devices in your home have limit switches. A limit switch simply stops an electic device from functioning under certain circumstances. A simple example is the light that turns on when you open your refrigerator door. Limit switches not only save energy but also are a safety feature for many appliances.
Your Air Conditioner’s Limit Switch
The limit switch in your air conditioning is between the air handler and the thermostat. The thermostat senses the temperature in the room, and when the desired temperature has been reached, it sends a signal so the air conditioner to stop producing cold air. The blower should turn off at the same time, or it will start circulating warm, unconditioned air throughout your home. On the other hand, if the blower turns off too soon, the cool air that your air conditioner is producing won’t be distributed throughout your home. The limit switch makes sure that your blower and your air conditioner turn off at the same time.
While this might seem like a small, unimportant component, it actually has a very important role in keeping your air conditioner functioning efficiently. If your air conditioner seems like it is shutting on and off more frequently than usual or is not cooling your home effectively, it could be a problem with your limit switch. Sometimes resetting your limit switch will fix the problem, but if the switch is broken, you will need a professional to come out and replace it.
