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

When your air conditioner is on the fritz, there could be a number of things wrong with it. However, in order to get it back up and running properly as soon as possible, you could try troubleshooting a couple of simple fixes. One of the things an AC repair company will try to determine is whether you have a faulty AC sensor. Why is that important?

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. Without the thermostat, most air conditioner systems will not know when to turn on. 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 is located near the evaporating coil. Its role is to measure the air’s temperature in the evaporating coil and change 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. 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 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 should be replaced because simply repositioning it won’t solve the problem.
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 the thermostat is broken.
However, if you set the thermostat to a high temperature and the air conditioner system continues to cool, it is likely that the sensor 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 fix the AC sensor issues, call a professional. A professional HVAC contractor will be able to determine 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.
