Your air conditioner is an intricate design of electrical relays, pressurized liquid, and mechanical parts. When all of these parts work harmoniously, your home is perfectly air-conditioned to the set temperature and air conditioning repair is the least of your worries. However, air conditioner sensor problems can quickly change your indoor climate. From cycling too much to not turning on at all. It is however that a faulty sensor may just need a basic adjustment… or not!

How A Thermostat Sensor Works

Your thermostat sensor resides near the evaporator coil within your inside air conditioning unit. As air moves past the sensor and coil, it notes the temperature and compares it to the desired temperature. If the home or business needs to be cooled further, for example, the sensor activates the compressor. The machine which effectively cools your home until the temperature at the sensor matches the set temperature. In response, the sensor shuts the compressor off, effectively turning off the air conditioning.

Symptoms To Look For

If your ac home sensor is not working properly, it can cycle on and off, with little time between activation periods. The home can be too cool or too hot, even if you adjust the temperature setting at the control panel. If you allow the system to continue on this unusual cycle, critical components may break down. Because “It’s All About Your Comfort.” The Cooling Company wants you to preserve your system for as long as possible.

Simple DIY Air Conditioner Sensor Repair

Turn off the air conditioner, and remove power from it completely by shutting off the breaker at the main electrical panel. Access the indoor air conditioning unit’s evaporator coil. It may seem hidden with a cover on it for protection. The sensor should be extremely close to the coil. If it is touching the coil or bending away from it, you have found your sensor problem.

Carefully bend the sensor back into place. It needs to be close to the coil for an accurate temperature account. Any unusual angles toward or away from the coil causes the erratic air conditioning behavior as seen before. Turn the breaker back on and activate the air conditioning. It should work normally now

Our #1 recommendation for safety’s sake, however, is to always contact a professional like those at The Cooling Company for all your HVAC needs. If you adjust your sensor, and the system is still erratic, we need to evaluate your air conditioner. There may be any number of other issues causing problems. We will always give you a fair estimate based on our evaluation to make your system work reliably again. Avoid any long-term damage to your air conditioning by allowing us to evaluate your issues. That simple problem can quickly evolve into a large headache if left unaddressed!
