If your Honeywell thermostat is displaying a “Cool On” message and blinking, but the unit is not actually cooling, there are several potential causes. First, check to make sure that the batteries in the unit are fresh and have enough power. Next, check that all of the wires are properly connected.
If everything looks good there, then the problem may be with the outdoor air conditioning unit itself. If you’re not comfortable troubleshooting further on your own, contact a professional HVAC technician for assistance.
If your Honeywell thermostat is flashing “Cool On” but not working, there are a few things you can check to troubleshoot the issue. First, make sure that the batteries are fresh and installed correctly. If the batteries are low or installed incorrectly, the thermostat may not function properly.
Next, check to see if the furnace filter needs to be replaced. A dirty furnace filter can cause the thermostat to malfunction. Finally, consult your Honeywell user manual for further troubleshooting tips.
