The air conditioning thermostat is an important part in all cooling devices such as air conditioners and refrigerators. Not only does it help keep temperatures in check, it also allows different users to customize them to their liking.
Can you imagine not being able to set your aircon unit’s desired temperature level for your comfort and relaxation? Exactly.
In this article, we’ll walk you through the different types of an air conditioner thermostat, their basic features, and the simple ways of fixing a broken one.
The Different Types of an Aircon Thermostat
An air conditioning unit thermostat usually comes in different types and is usually split into two categories: mechanical and electronic. There is also the programmable type that is usually found in more modern buildings and houses.
But make no mistake about it: while these air conditioner unit thermostat types differ in size, shape and form, they are still designed to perform one essential function — to control and maintain the unit’s cooling capacity at a desired temperature level. Let’s look at them in closer detail:
1. Mechanical Type
These thermostats are commonly used and found in different buildings, establishments and hotels. It’s usually marked in degrees Celsius and can be set easily to one’s own liking. This thermostat also doesn't switch on and off at a single temperature. Instead, it is known to cycle between small increments of temperatures on either side of the level that you set. Thermostats of this type also come at a relatively lower cost compared to electronic types.
2. Electronic Type
While it comes at a slightly higher cost than its mechanical counterpart, electronic type thermostats are considered more accurate in temperature control (up to 0.5°C). They are commonly used and favored by establishments that prefer to have an automated building management system.
As a matter of fact, the sensor used for electronic types is usually an NTC thermistor. This thermostat type also has digital displays — LCD or LED — for room temperature levels. These displays often include the set temperature and sometimes even the outdoor temperature levels of a space. A more complicated system will have error codes that help the users to determine the fault that occurred in the system.
3. Programmable Type
As the more recent iteration of thermostats, the programmable type is a common favorite among more modern houses and establishments. While it possesses some of the basic features of a typical electronic thermostat, its features have been significantly improved and added with new features that prove to be valuable to some people.
Included among these features is the special function to set different temperature levels at different given times in a day. But the one that seals the deal is an intelligent energy-saving mode to conserve electricity. Pretty cool, right?
What Causes Aircon Thermostat Failure: 3 Common Signs to Watch Out For
Since the aircon thermostat serves as the aircon unit’s main control panel, it’s only important to keep it in great shape at all times. That’s why we always recommend keeping an eye out for these 3 common signs of aircon thermostat failure:
1. The thermostat doesn’t turn on or is unresponsive
One common sign that your thermostat is headed for the repair circuit is if it begins to exhibit signs of instability. If you find that your thermostat isn’t being responsive to taps or clicks, then it might be in need of a proper fix.
2. The air conditioner doesn’t cool or heat when turned on
Is your aircon having difficulty cooling or heating the room? You might be dealing with a faulty aircon thermostat. To troubleshoot the issue, try switching your thermostat on and off. But if this still doesn’t do the trick, consider calling an aircon expert to help you diagnose and fix the issue right away.
3. The air conditioner is not consistent with its cooling and heating
Another tell-tale sign of a faulty aircon thermostat is an AC unit that stops midway in cooling or heating a room. If you’re dealing with this problem, you need to schedule a repair and maintenance appointment with a service provider to prevent further damage in the thermostat or unit.
How To Fix a Broken Air Conditioner Thermostat?
Here are three quick and easy ways that you can do to troubleshoot a broken air conditioner thermostat:
1. Change the batteries
Sometimes a faulty air conditioning thermostat is just the result of expired or empty batteries. To save time and effort, check first if your thermostat is just asking for a quick battery change rather than a total maintenance fix.
2. Dust it away
Using a small paintbrush or a clean cloth, open up your air conditioning thermostat panel and sweep away some of the dust and dirt that have accumulated. Sometimes the panel just needs some good ol’ dusting to have it back up and running again.
3. Check the thermostat location
Another quick fix that you can do is to make sure whether your air conditioning thermostat is not directly placed under the sunlight’s glare or heat. If your thermostat is acting up, simply try removing it from any close source of heat and see if it does the trick.
