Check the connection between the thermostat and the two leads that lead to cooling for the AC at the wall.

SOURCE: On my honeywell thermostat cool on keeps on

On a Honeywell thermostat the flashing means that the system is in a delay to turn on the compressor. This is used to protect the compressor from coming on and off too often. The normal delay is about 5 minutes. After that the system should come on. If not there is s problem.

In order to help us help you we will need a little more information. What happens either at the inside unit or at the outside unit after the thermostat stops flashing "Cool"? Any fans come on? Do you hear a "KLUNK"? Any sparks? Please let us know so we can help.

What does the snowflake mean on a Honeywell thermostat in cooling mode. Also had the problem in the heating mode.


The snowflake means it's cooling. If the outdoor unit is not running then the problem is likely outside.

I have a Honeywell RTH6580WF Wi-Fi Thermostat that has "Cool On" or "Heat On" flashing in an endless loop. Could there be a major issue?


Pull the power red wire off the thermostat and batteries out if it has battery backup, then reinstall...much like a computer restart. If this doesn't work, then replace your thermostat.

My Johnson Control Thermostat is just blinking AC not the snowflake or cooling. I can't see the temperature or anything like that? It' just flashing AC.


I recommend you go to Honeywell site and type in your thermostat model etc. It will give you step by step procedures and may provide the answers you are seeking.

The thermostat is not cooling to set themperature. The cool on light is flashing.


ok, your thermostat doesn't do any cooling! your a/c does the cooling. is the equipment running? is your air filter clean? is your refrigerant charge ok?
