It’s hot. You’re hot. Your home is hot. Time to turn up the air conditioning so you can get some relief!
But wait. It’s cool outside, but your air conditioner says it’s hot. What is going on?
The thermostat on your wall might be broken. You might have a hot day but your thermostat setting is set at 72 and you’re experiencing 80 degrees Fahrenheit heat.
That’s a nightmare. The thermostat set at 72 but reads 80 phenomena dates back to the past quarter century.
Check for Airflow Obstructions
If your thermostat is set to 72 degrees but is reading 80, this could indicate a variety of issues, but the first step to take when diagnosing the issue is to check for airflow obstructions. Airflow obstructions can be anything from a dirty air filter, to an obstructed vent, to an issue with the fan itself.
Make sure to inspect each of these areas for obstructions and then add any necessary cleaning or maintenance. If the obstructions are resolved and the thermostat is still not reading the temperature correctly, then it may be time to replace the thermostat altogether.
Check for Accuracy with a Digital Thermometer
A thermostat set at 72 degrees may read 80 if it isn’t working accurately. To check the accuracy of your thermostat, you should use a digital thermometer. This will allow you to confirm whether your thermostat is reading accurately or not.
With a digital thermometer, you can measure the temperature of the room where your thermostat is placed and compare the reading to the thermostat. If there is a significant difference between the two readings, then the thermostat may be faulty and need to be replaced.
Investigations into Temperature Setting Errors
Investigations into HVAC problems can usually be done by troubleshooting the thermostat that is set at 72° but reads 80°. Common issues could be a faulty temperature sensor, or issue with the thermostat’s wiring, or dirt or dust causing the unit to overheat.
If the cause is a faulty sensor, then replacing it is the recommended solution. If the issue is with the wiring, then taking the unit apart and thoroughly cleaning it should help. Depending on the age and condition of the thermostat, replacing it with a new one might be the best option.
Possible Causes of a Miscalibrated Thermostat
A miscalibrated thermostat can cause a variety of misunderstandings and confusion when it comes to interior climate control. For example, a thermostat set at 72 degrees but reads 80 degrees can be frustratingly inaccurate.
Causes of a miscalibrated thermostat can include dirt or dust on the sensing mechanism, power outages, or a worn out or low battery. Other possible causes of a miscalibrated thermostat can include a loose wiring connection, a misaligned temperature sensor, or an aged and worn thermostat.
