Signs Your Thermostat Should Be Repaired

At the heart of a comfortable home is a thermostat. Without a thermostat, you can’t control the temperature of your home, rendering the rest of your HVAC equipment from Rosenberg Plumbing & Air useless. Even with a thermostat, though, you can still run into problems that temporarily interrupt the flow of conditioned air throughout your San Antonio home. To help your thermostat operate properly, here are a few signs to watch for that may indicate it’s on the fritz:

The Screen Is Blank

On programmable and smart thermostats that display the current temperature and other information, a blank screen is a sure sign of a problem. In many cases, the problem is as simple as a dead battery in the thermostat that needs to be changed out. If this doesn’t fix the issue, though, then you could have an issue with your wired power supply or with the display itself. Start by replacing the battery, and if that doesn’t work, call a technician from Rosenberg Plumbing & Air to further diagnose your troubles.

The System Won’t Turn Off or On

Within your thermostat are multiple connections that are required for your HVAC system to turn off and on properly. Each component in your HVAC system is separately connected to the thermostat. This allows the thermostat to send an electrical signal to the components in the order that’s necessary for everything to work as it’s designed. If one of these connections comes loose, your thermostat will protect the other components by preventing the entire system from turning on.

In some cases, you can diagnose this problem on your own. By removing your thermostat’s faceplate, you can see the electrical connections and check to make sure that they’re all properly connected. If all the connections appear to be tight, you’ll probably want to contact someone from Rosenberg Plumbing & Air for assistance because there could be a problem elsewhere in the power supply chain that’s preventing your HVAC system from starting or stopping.

The Temperature’s Not Right

Another issue that you can run into with a thermostat is that it can begin to detect the temperature incorrectly. In every thermostat, both mechanical and electronic, there is a device to detect the temperature so that the thermostat knows when to engage the HVAC system.

In electronic thermostats, this is typically some type of thermistor, which is a type of metallic transistor that changes depending on the surrounding temperature. If the metal in the thermistor or other sensor degrades, your thermostat won’t be able to accurately sense the temperature, meaning your HVAC system from Rosenberg Plumbing & Air will turn off and on at times when it’s not necessarily needed. If the temperature sensor malfunctions, it’s typically best to have a new thermostat in case there were other components of the thermostat damaged by the malfunctioning temperature sensor.

There’s No Connection

Though smart thermostats are excellent devices to help you save energy, they do come with potential challenges that other types of thermostats don’t have. For example, you may run into an issue in which your thermostat is unresponsive and can’t be controlled from your phone.

In most cases, this is caused by a momentary interruption in the Wi-Fi connection and will fix itself. However, if the problem happens repeatedly, it may be due to a malfunctioning Wi-Fi chip in the thermostat. If resetting your thermostat doesn’t fix the problem, then you may need to replace the thermostat or your router to see if that fixes the issue.
