A reliable thermostat is vital to a safe and comfortable environment in your home. However, as important as it is, it is not immune to malfunctioning. Learn about the ways you can tell that your thermostat is failing.
Short Cycling
Short cycling is when your HVAC system turns on and off frequently without completing a full cooling or heating cycle. This problem puts added stress and strain on the HVAC parts. It also wastes energy and raises your monthly utility bills.
Not Turning On or Off
A failing thermostat can also prevent your system from turning on and off normally. Instead, your HVAC system may fail to start. It may also run non-stop, using more energy than usual, wearing out your system, and increasing your utility bills.
Inaccurate Readings
A failing thermostat often provides inaccurate readings. Your home might feel hotter or colder than the temperature displayed on the thermostat. This problem often means that the sensor is miscalibrated or that the entire thermostat is failing.
Unresponsive Controls
Unresponsive controls are another easy way to know that your thermostat needs either repair or replacement. It should respond when you press its buttons or adjust its settings. When it fails to turn on or off or raise or lower the temperature setting, the culprit could be either internal damage, like loose or frayed wiring.
Flickering or Blank Display
A dead screen or one that fades often tells you that the thermostat has a power problem. The underlying issue could range from dead batteries or internal faults. It could also mean that the thermostat has a blown fuse or tripped breaker.
No Clicking Sound
When the thermostat activates the system, you should hear it make a faint clicking sound. However, an absence of clicking could mean that the thermostat is failing. The problem could stem from a faulty relay, damaged or loose wiring, or a malfunctioning control board.
Losing Its Settings
A smart thermostat that loses its settings tells you that something is amiss and could require professional repairs or a replacement. The problem could be as simple as a low or old battery. However, this issue can also occur because of a loose connection, an interruption with its 24V C-wire, or a software glitch.
Inconsistent Room Temperatures
When a thermostat fails, it can create uneven temperatures in rooms throughout your house. Some parts of the house may feel hotter or colder than others, depending on the season. This problem means that the thermostat is not regulating the HVAC system.
Age
A thermostat that is older than 10 years could be due for replacement. Most modern thermostats have a lifespan of a decade. Some smart thermostats, however, need replacing every five to seven years.
