New Honeywell Thermostat Blowing Hot Air on Cool Fixing Guide
One of the most common reasons for your new honeywell thermostat cool on but not working is incorrect thermostat settings.
To resolve this issue, follow these expert tips to ensure your thermostat settings are configured correctly:
Mode Selection
– Locate the mode selection switch or button on your thermostat.
– Ensure it is set to “Cool” or “Cooling” mode. This tells your thermostat to activate the air conditioning system for cooling.
