Helpful Information
Your thermostat controls your HVAC to keep your house at a consistent temperature – which is why it is so frustrating when your thermostat isn’t displaying the right temperature.
If your thermostat is on the fritz, you can’t set temperatures correctly. But BEFORE calling an HVAC technician, read this guide on why your thermostat isn’t showing the correct temperature & the solution.
HVAC System Is the Wrong Size
The most likely issue is calibration problems because your HVAC system is too large or too small. If your system is the wrong size for your home, then your thermostat won’t be able to reach the correct temperature before the system shuts down and cycles again.
Thermostat Placement Problems
If your thermostat is positioned right next to a window or a heat source, it can start displaying the wrong temperature. For instance, a thermostat right next to a heater vent might read the temperature as higher than it is.
The ideal position for your thermostat is at least 5 feet from the floor on a section of wall that doesn’t have any doors, windows, vents, or skylights.
Sensor Faults
Most modern thermostats use special electrical plates called thermistors to sense ambient temperature and adjust HVAC performance accordingly. If the sensor plates are caked with dust, your thermostat can start showing the wrong temperature. You can clean thermostat sensors using a soft brush to get rid of accumulated dust and debris.
Power & Wiring Issues
Another reason why your thermostat may not be showing the correct temperature is due to power and wiring issues. Wires connecting your thermostat might be frayed, which can cause the screen to malfunction and show wrong temperatures. You may have to install a new thermostat to fix the temperature issues if you can’t replace the corroded wires.
