AC Temperature Sensors: Types, Uses & Benefits

Air conditioning systems are necessary for maintaining indoor comfort, and temperature sensors play a key role in their functionality. These sensors constantly monitor the temperature of the room, thereby ensuring that the air conditioning system works properly in regard to operations. This blog will discuss the basics of AC temperature sensors, the types that they use, how they work, how to tell if there are any issues, solutions to fix them, and frequently asked questions to answer some of the common concerns. 

What are AC Temperature Sensors?

AC room temperature sensors measure the air temperature in a room or the system itself. The data is fed into the control unit of the air conditioning compressor, which simply switches the cooling cycle according to the set temperature. The absence of these sensors renders an air-conditioning system to be inefficient or even incapable.

What Types of Temperature Sensors Are Used in AC?

The NTC temperature sensor is the most common and widely used across all kinds of AC segments to measure the room & coil temperatures.

Thermistors

Thermistors have extremely high sensitivity and provide highly accurate performance temperature readings. It is very effective and an almost universal instrument in household air conditioning applications.  

How Do AC Temperature Sensors Work?

An air temperature sensor AC constantly observes the temperature of the room or detects the evaporator coil. It goes like this as follows:

1. Temperature Sensing: The sensor detects the variation of temperature. 
2. Signal Transmission: It converts the temperature data into electrical signals and transmits it to the control board. 
3. System Adjustment: Based on the data, the control unit adjusts the compressor and fan to maintain the desired temperature in the room.

This is the methodology by which the AC "senses" temperature and keeps the room cool or warm as required. 

How to Identify if an AC Temperature Sensor is Not Working

It could indicate that your air conditioning system is malfunctioning and may require the replacement of the sensor. The following are common symptoms:

1. Irregular Cooling: The room sets a temperature but is too cold or too hot. 
2. Frequent Cycling: The AC turns off a lot, and it's never getting cold. 
3. Error Codes: Error codes that report sensor issues are common nowadays in modern AC. 
4. Unresponsive Thermostats: No matter how you adjust the settings on the thermostat, it still won't manipulate heating or cooling.

How to Fix an AC Sensor Problem  

In the case of perceiving malfunctioning of the AC temperature sensor, please follow the subsequent measures:

1. Inspect the Sensor

1. Locate the sensor, usually around the evaporator coil or into the indoor unit. 
2. Check for visible damage, dirt, and disconnection. 

2. Clean the Sensor:

1. Use a soft cloth to comfortably dust the sensor without scratches or scuffmarks.

3. Check the Wiring:

1. Use a soft cloth to comfortably dust the sensor without scratches or scuffmarks.

4. Test the Sensor:

1. In different temperatures, use a multimeter to check the sensor's resistance. Compare it against the boundaries provided by the manufacturer.

5. Replace if Necessary:

1. In case your sensor has developed some malfunction that cannot be repaired, replace it with the appropriate type for your AC model.

Pro Tip: It is always recommended to consult the AC manual or a professional technician when repairing things.

Why JR Sensors are Popular in AC Systems  

JR Sensors are among the well-known brands in HVAC (heating, ventilation, and air conditioning) products. Their sensors are highly precise and durable and above all, reliable. Some of their key features include:

Temperature sensitive to extreme changes.  

1. Compatible with Different Models of ACs.  
2. Strongly built to withstand all kinds of environments.  
3. Pretty easy to install and upkeep.

JR Sensors are greatly preferred by a number of manufacturers owing to consistent performance along with cost-effective solutions.

Conclusion 

The AC temperature sensor is a component for making a scene deep inside you. Therefore, understanding the kinds and other functions as well as problems related to air conditioning temperature sensors will allow you to troubleshoot and fix them. However, for any major repairs, always call upon a professional technician. In fact, with good care, regular maintenance can ensure that these temperature sensors will cool your AC for years to come.
