Signs Your Thermostat Needs to be Replaced

The simplest defects can shut down your temperature control system quickly. A thermostat will often send signals that indicate it needs to be replaced right away. What signs should you look for?

1. System Doesn’t Turn On

When you set your thermostat to the desired temperature and turn it on, it should automatically startup. If it doesn’t, you could have a faulty thermostat. Wiring can come loose over time, or a component inside the gauge’s housing can stop working. An experienced technician will need to replace the unit, reattach wiring or both, depending on what’s happened.

2. System Runs Constantly

Air conditioning and heating systems connected to a thermostat are designed to operate until the requested temperature has been reached. Once that’s happened, they should automatically turn off. The unit will turn back on when the sensor identifies a drop or rise in temperature. Again, it will fill the interior space to meet the required temperature. When the unit continuously runs and doesn’t shut off, it’s a sign that the thermostat is broken and needs a replacement. That’s when it’s time to call a qualified service team in Mission for a repair.

3. Indoor Temperature Doesn’t Match Thermostat

Suddenly, you notice that the air inside your home isn’t matching the thermostat’s settings. While this issue can occur due to a loss of refrigerant, it can also point to a faulty thermostat. If you’ve got a zoned system, then variations from room to room are normal, and further investigation may be required.

4. Thermostat Readout Goes Blank

Your system is working fine when you leave the house in the morning. However, when you return a few hours later, the readout is blank. Replacing the batteries could solve the problem. If that doesn’t work, a technician can test the thermostat and know immediately whether a replacement is necessary.
