If you’re experiencing problems with your AC thermostat, don’t worry – you’re not alone. Many homeowners face similar issues every year.
We’ve put together this blog to outline the common thermostat problems and their solutions. By understanding what to look for and how to fix these issues, you can save yourself time and money. So read on to learn more.
- The Thermostat Is Not Calibrated Correctly, Resulting in Incorrect Temperature Readings
Thermostat calibration is essential for accurate temperature readings. If the thermostat is not calibrated, it can turn your AC unit on and off at the wrong times or not cool your home to its temperature. You can calibrate your thermostat yourself or hire a professional to do it for you.
If you notice that your home is not cooling to the temperature you set on your thermostat, or if your AC unit seems to be turning on and off more frequently than usual, it may be time to calibrate your thermostat.
To calibrate your thermostat:
-Turn off the power to your AC unit at the breaker box
-Remove the thermostat from the wall
-Check the manufacturer’s instructions for how to calibrate your specific model of thermostat
-Follow the instructions and reattach the thermostat to the wall
-Turn on the power to your AC unit at the breaker box
- Condensation Forms on the Thermostat and Causes It to Malfunction
When the air conditioning system is running, the evaporator coil inside the unit produces condensation. This moisture is supposed to drain outside your home. However, if your AC’s drainage system is blocked, this water can drip onto the thermostat and cause it to malfunction.
If you notice condensation on your thermostat, experts can help by:
-Inspecting your unit’s drainage system
-Clearing any blockages in the system
-Repairing or replacing any damaged parts of the system
These steps can help prevent future condensation issues and keep your thermostat working correctly.
- Dirt and Dust Accumulation on the Thermostat Can Cause It to Malfunction
If you live in an area with a lot of dust or dirt in the air, it’s essential to keep your thermostat clean. Over time, dust and dirt can accumulate on the thermostat and cause it to malfunction.
Expert technicians will use compressed air to clean the thermostat and remove any dirt or dust accumulated. If you have a dirty or dusty thermostat, it’s essential to have it cleaned by a professional as soon as possible.
- The Thermostat Is Not Hardwired Properly, Leading to Erratic Operation or Complete Failure
The wiring to your thermostat is relatively simple, but if it’s not done correctly, it can cause problems. For example, if you have a digital thermostat, there should be four wires: red (24v power), green (fan), white (heat), and yellow (cool). If any of these are loose or disconnected, the thermostat won’t work correctly.
An HVAC technician can quickly check the wiring and make any necessary repairs. They use special equipment to test for voltage and continuity to ensure the wiring is correct.
If you’re having trouble with your AC thermostat, it’s best to call in a professional. They have experience dealing with all types of thermostats.
