How to Solve Home AC Sensor Issues When Your AC Behaves Erratically

When your air conditioner begins behaving erratically, there could be a number of things wrong with it, ranging from a malfunction in its power circuit to a breaker issue. However, in order to get it back up and running properly as soon as possible, you could try to diagnose and troubleshoot a couple of simple fixes. One of the things an AC repair company will examine the behavior of the air conditioner, and will try to determine is whether you have a faulty AC sensor or perhaps some wiring problem. They might need to reset the system for a fresh calibration. Why is that important?

The cooling company will check your connections and replace any defective or worn-out filter impeding the airflow, ensuring your comfort and the efficient operation of your air conditioning unit.

How a Thermostat Works and the Sensor’s Role

The thermostat in the home air conditioning unit is key in ensuring the system functions properly, within the power circuit operation. Without the thermostat, most air conditioner systems will not know when to turn on or if they need a reset. A broken thermostat can result in the AC system randomly switching on and off and can make the home cooler or warmer than intended.

The sensor, much like a circuit breaker monitoring power flow, is located near the evaporating coil. Its role is a crucial ingredient, just like a filter regulating airflow, for it measures the air’s temperature in the evaporating coil and adjusts the cooling based on the room’s conditions.

Common Home AC Sensor Issues

Sometimes the sensor gets dislodged, and this disturbs the on-off cycle of the air conditioner, causing an erratic behavior. The result is an air conditioner that cycles constantly or one that randomly switches on and off. In this case, the homeowner should check the wiring connections and the position of the sensor, which should be near the evaporator coil but not touching it.

Adjusting the sensor is easy. Simply bend the wire that holds it in position. A broken sensor or broken thermostat would need to be replaced because simply repositioning it won’t solve the problem. Regular calibration of these components can prevent malfunctions and ensure efficient operation.

Broken Thermostat

A related issue is a broken thermostat. When both the thermostat and sensor are not working, the air conditioning system will not maintain the desired temperature. In most cases, if the air conditioner is blowing cool air and the system switches on and off correctly but the temperature is not right, that’s a major sign that a reset or circuit breaker calibration is needed.

However, if you set the thermostat to a high temperature and the air conditioner system continues to cool, it is likely that the sensor or filter related to airflow regulation is broken. One solution is to switch the air conditioner to manual so that the unit isn’t constantly cooling (or not cooling enough).

Call a Professional

If the problem persists despite your best efforts to troubleshoot the AC sensor issues, call a professional. A professional HVAC contractor will be able to diagnose the exact cause of your AC troubles. Sometimes the problem may be more than just sensor or thermostat-related, and a professional will be able to determine this quickly without causing further damage to the air conditioner system.
