Performing a soft reset on your Carrier Infinity thermostat can resolve minor glitches. This quick process helps restore normal function without erasing your settings. Follow these simple steps carefully to ensure a smooth reset.
Turn Off System
Start by turning off your HVAC system at the thermostat. Press the power button or switch the system to the “Off” mode. This stops the heating or cooling and prepares the thermostat for the reset. Make sure the display goes dark or shows the system is off.
Cut Power At Breaker
Next, locate your home’s electrical panel. Find the breaker that controls the HVAC system. Flip the breaker switch to the “Off” position to cut power completely. Leave it off for about 30 seconds. This step clears the thermostat’s memory and resets the internal controls.

Clean Thermostat Unit
Dust and dirt inside the thermostat may cause it to malfunction. Use a soft brush or cloth to clean the exterior gently. Open the thermostat cover and blow out any dust with compressed air. Avoid using water or cleaning liquids. Keep the area around the thermostat free from dust and debris. Clean units often respond better and avoid false readings.
