If you have a Honeywell thermostat and it’s flashing “COOL” on the display, there are a few things you can do to troubleshoot the issue. First, check to make sure that the batteries are charged or replaced. If the batteries aren’t the problem, then it’s possible that your thermostat is set to “Cool On” instead of “Auto.”
To change this setting, simply press the “Mode” button until it says “Auto.” Finally, if neither of these solutions works, you may need to reset your thermostat by pressing the “Reset” button for three seconds.
If your Honeywell thermostat is flashing “Cool On,” it means that the unit is in cooling mode and the compressor is running. This is a normal operation. If the unit is not providing cooling, check to make sure that the temperature setting is below the current room temperature and that there are no obstructions blocking airflow to or from the unit.
What Does It Mean When the Honeywell Thermostat is Flashing “Cool On”?
If you see the “Cool On” message flashing on your Honeywell thermostat, it means that the unit is turned on and cooling is active. The message will flash until the set temperature is reached, at which point it will stay lit steady.

The thermostat Blinking Cool On, But No Air
If your thermostat is blinking “cool on” but there’s no air coming out of the vents, don’t panic! There are a few possible explanations for this issue.
First, check to make sure that your furnace is turned on and that there’s power running to it.
If everything looks good there, the next step is to check your air filter. A dirty filter can restrict airflow and cause all sorts of problems, including a blinking “cool on” light on your thermostat.
If your filter is clean (or you’ve replaced it with a new one) and you’re still seeing the same issue, the problem could be with your furnace itself.
It’s possible that the furnace isn’t producing enough heat to trigger the AC system. This could be due to a faulty igniter or another issue within the furnace.
If you’re not comfortable troubleshooting the issue yourself, contact a professional HVAC technician for assistance.
They’ll be able to diagnose and fix the problem quickly so you can get back to enjoying cool, comfortable indoor temperatures!
Honeywell Thermostat Cool on But Not Working
If your Honeywell thermostat is displaying “cool on” but not working, there are a few possible reasons. First, check to make sure that the batteries are fresh and installed correctly. If the batteries are fine, then the issue may be with the wiring.
Check to see if any of the wires are loose or disconnected. Finally, if all else fails, you may need to reset the thermostat by turning it off and then back on again.
Honeywell Thermostat Flashing Cool on After Changing Batteries
After changing the batteries in my Honeywell thermostat, the screen saver now says “Cool On” and the house is not cooling. What’s wrong?
Most likely, you have a wire that has come loose from the terminal.
To fix this, open up your thermostat and check all of the wires to make sure they are tight on their respective terminals. Once you have verified that all of the wires are secure, put the cover back on your thermostat and turn it on. The “Cool On” message should no longer be displayed.
The thermostat Says Cool on But No Air
If your thermostat says cool but there’s no air coming out, there are a few potential causes. First, check to see if the vents in your home are open. If they’re closed, opening them should allow air to start flowing.
Another possibility is that the fan isn’t turned on. In most cases, you’ll need to turn it on manually. Finally, it’s possible that your air conditioner is simply low on refrigerant.
If this is the case, you’ll need to contact a professional for assistance.
Honeywell Thermostat Blinking on And off
If you have a Honeywell thermostat, you may have noticed that it blinks on and off occasionally. This is normal behavior and nothing to be concerned about. The blinking indicates that the thermostat is in standby mode, waiting for a command from the user.
When the user presses a button or makes a change to the settings, the thermostat will wake up and respond accordingly. There’s no need to worry if your Honeywell thermostat is blinking on and off – it’s just doing its job!
Honeywell Pro Series Cool on Blinking
If you have a Honeywell Pro Series thermostat, you may have noticed that the cool button blinks when the system is on. This is normal operation and indicates that the system is working to maintain the set temperature. The cool button will blink until the set temperature is reached, at which point it will remain lit.
If the room temperature rises above the set point, the system will turn back on and the cool button will begin blinking again.
Honeywell Thermostat Reset
If your Honeywell thermostat isn’t working properly, you may need to reset it. Here’s how to do that:
First, turn off the power to the thermostat at the breaker box.
Then, remove the thermostat’s cover and locate the reset button. Press and hold the reset button for about 30 seconds.
Once the reset button has been pressed, turn the power back on at the breaker box and see if the thermostat is now working properly.
If not, you may need to replace it.
Pro T701 Thermostat Flashing Cool on
If you see your Pro T701 thermostat flashing “Cool On,” this means that the system is actively cooling your home. This can happen for a number of reasons, but the most common reason is that the temperature inside your home has reached the set point on the thermostat. The Pro T701 is designed to keep your home comfortable, so it will automatically turn on the cooling system when the temperature rises above the set point.
There are a few things that you can do if you see your Pro T701 thermostat flashing “Cool On.” First, check to make sure that the temperature inside your home is actually above the set point. If it is, then there’s nothing to worry about – the system is just doing its job.
However, if the temperature isn’t above the set point, then there may be an issue with the thermostat itself. In this case, you should contact a professional for help.
In summary, if you see your Pro T701 thermostat flashing “Cool On,” don’t panic!
It’s likely that everything is working as it should be and that the system is just keeping your home comfortable. However, if you’re unsure about what’s going on, or if you think there may be an issue with the thermostat, don’t hesitate to contact a professional for help.
Conclusion
If your Honeywell thermostat is flashing “COOL On,” it means that the unit is in cooling mode and the compressor is running. The fan will also be on, but may cycle off and on depending on the model. If the room temperature rises above the set point, the fan will come back on to cool things down again.
