If your air conditioner isn't working correctly, it could be your thermostat. Your thermostat is a relatively simple appliance that provides a vital function. Whether you have a simple thermostat that goes "on and off" or a more complex smart thermostat, you may want to investigate it when you experience issues.
The Twin Roles of a Thermostat
A thermostat chiefly does two things: it turns your air conditioner system on when needed and it detects ambient temperatures. If either of these features go wrong, the entire air conditioning system will seem as though it's not working.
Some common problems with a thermostat include:
- Not reading temperature correctly. A thermostat can be thrown off if the area it is in is hotter than others. It also may not be very effective if there's only a single temperature sensor for multiple floors in the home. Split systems are intended to fix this, creating a different central air "zone" for different areas. Thermostats can have their temperature capabilities damaged if they're placed in an area that gets too hot, such as if a hot lamp is placed by them.
- Not turning on the HVAC system when it should. If the temperature on the thermostat reads correctly but the HVAC system isn't triggering properly, then the wiring may not be correct. It's possible that a wire is loose.
- Not turning on the AC fan. If there's a humming from the air conditioning system but air isn't coming out of it, it's possible the thermostat has turned on the AC, but hasn't engaged the fan. Many thermostats control the fan directly and separately from the rest of the system. Again, this could be a wiring issue.
- Turning the AC intermittently. Even many simple thermostats have scheduling capabilities. It's possible that the scheduling system is set incorrectly, turning the system on and off due to these settings.
A thermostat is fairly simple, which means a professional can fix most thermostat problems quickly.
Advanced Thermostat Features
Today there are many smart thermostats that have more advanced features. This improves their value and convenience, but could also lead to more complex issues. Smart thermostats can experience issues such as being programmed incorrectly. It may need to be rebooted or reset.
