How to Detect a Faulty Thermostat
Every home HVAC system has a thermostat that allows the homeowner to control their home temperature. While there are many different types of thermostats out there, they all work pretty much in the same way. You either turn the dial or use digital keys to set the temperature you want a room to be. The thermostat then monitors the room's temperature and turns on the HVAC system when the temperature is not at the desired temperature that you set.
No Power To The Thermostat
The first sign that your thermostat may be faulty is when you notice that it has no power. For digital thermostats, the screen will just be completely blank. When you hit the power button, it will not turn on. You want to go down to your electrical panel and ensure that your HVAC system's breaker is in the ON position. If so, you want to change out the batteries in your thermostat. In most cases, changing the batteries will fix the issue. However, if your thermostat is still not working, you may need to replace the thermostat.
Your HVAC Unit Won't Turn On
One frustrating issue that you may encounter is a thermostat that seems to be working, but your HVAC system doesn't turn on. You want to start by checking the set temperature. If you have another manual thermostat in the room, take a look at it and see if the temperature is the same as the one on your thermostat for your HVAC system. If the room's temperature is nowhere close to the set temperature on your thermostat, then it's likely that there is faulty wiring between your thermostat and your HVAC system. With this type of problem, it's advisable that you speak with an HVAC technician.
Your HVAC Unit Won't Turn Off
If you've noticed that your HVAC system has been continuously running, it's highly likely that you have one of two problems. The first is that your desired temperature setting is set far away from where the actual room temperature is. For example, you may have accidentally set your air conditioner to 45 degrees instead of 55 degrees. By taking a look at what your set temperature is on the thermostat, you can roll out this issue. The second issue is that there is faulty wiring between your thermostat and your HVAC system. Again, you want to call in an HVAC technician to help with this particular issue.
