Snowflake blinking in one zone

Our AC unit is working in two other zones. The main zone will not kick on and the snowflake is blinking - I've changed the batteries in the thermostat. Any other suggestions out there?

Thanks in advance!

I saw that my snowflake was blinking while the unit was in the 5 minute lock out state (after power up), but went to steady after that.

I have a digital Honeywell thermostat that has a blinking snowflake. When the thermostat is on auto mode it does not turn on. When I turn the thermostat to fan I can feel and hear the air blowing out of...


If the thermostat has a blinking snowflake then it is in time delay mode which sometime can take between 5 to 7 minutes before it will turn the AC and Fan On......Then it will go to a solid snowflake.
When you turned it to fan On it starts the Fan right away..... After the snow flake has went to solid check to see if the fan is running and then look outside to see if the Fan Blade is turning on the AC..... The fan blade comes on the same time as the compressor does. Then with the fan running hold your hand above the air stream above the AC and if you can noticeablely feel warm to hot air comeing out the Top then the compressor is running also. If the outside unit is not running I would check to make sure the Main Breakers are turned ON.... After the AC has ran for a few minutes feel the copper lines that go into the house the smaller line should feel warm to hot and the bigger lines with insulation on it should feel cool to cold and sweating with beads of moisture on it..... That is a quick test to see if the unit is working properly.....If you have a Thermentor and can Check the Temperature of the Return Air and the Supply Air .. You should have about 20 Degree F Between the Supply and Return........ 75* Return - 55* Supply would Equal 20* TD Across the Coil......
That is about all you can do to check on your own....... If the compressor is not coming on or the lines are not the temperature difference then you will need to get professional help for your Air Conditioning System..... Goood Luck Hope this Helps.........

My outdoor AC unit is not coming on. Air is blowing out of my vents inside but the snowflake symbol on my thermostat is blinking and the air isn't cold. The fan on the unit isn't even running. Any...


check power to outside unit, check if it has a fused disconnect, if you have power and no blown fuses it could be a blown capicator that starts the fan and compressor...............

Unit on wall is not getting cool, shows a snowflake, when I go outside our large AC is running but the little one is not


1. turn on the AC and go fast to the outdoor unit. hear the sound of the unit. if the compressor tries to start but it can't then you sould change the capacitor which is inside the outdoor unit.
2. Otherwise your compressor is damaged or there is a loose cable connection or one of the two printed circuits (inside-outside) has problem.

Snowflake blinking and air conditioner won't turn on.


If it is blinking it is in a 5 minute time delay.
It should settle to a steady snowflake after 5 minutes and come on normally.

My Honeywell rth230b thermostat continues to give me a flashing snowflake signal and will not allow the AC to turn on.


Your snowflake should flash for about five minutes, that is the time delay built into the thermostat. It should stop after that and your system should begin to function.
