Chesapeake, given your symptoms you'll be looking at installing a new Selector Switch. But, before you go there... UNPLUG THE UNIT OR SHUT OFF THE BREAKER!!! Your selector switch does two things at a time, It energizes the fan motor (which it IS doing) and energizes the compressor at the same time. The voltage to your compressor goes from the wall into the selector, out of the selector, through the temp control then to the compressor. When the temp control is satisfied, it interrupts power to the compressor. The click you hear is the temp control being NOT satisfied and trying to send power to the comp. But if there is "no power" to send (i.e., the selector switch has failed)the compressor won't know to engage. Remove the front panel and filter. Remove the control box housing. Remove the knobs from the controls. You will now see the selector switch. Remove the 2 screws that fasten it (don't remove the wire yet!) and install the new switch. Then, one wire at a time, remove the wires from the old switch and install them on the new one. ***If you have an OHM meter, check the temp control before ordering a selector because this may be the problem and NOT the selector! To do this... remove the 2 wires from the temp control, set the control to "coldest". Then with your meter, test OHM's between the terminals. If you see "zero" OHM's, it's good. If you see no change in your meter, it's bad and THIS is the source of your problem. If you don't have a meter... you can test using this procedure... cut a 6" length of wire and strip the ends to about 3/8", twist the copper ends tightly. Remove both wires from the temp control, then insert one end of your jumper wire into one terminal and the other end into the other terminal. Make sure the "jumpered" wires are away from anything metal!!! And plug the unit back in. Now turn the unit on. If the unit fires up? It's the temp control, If not? it's the selector switch.

SOURCE: Snowflake blinking in one zone

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.

SOURCE: Amana 1 ton Residential AC / Outside unit comes on for a sec

open the service panel to check for control voltage of 24volts when tstat calling, The contactor should be pulled in, if contactor is down,and contacts appear to be clean, and the unit is still not running, it is a bad compressor. to test this unplug the black wire from the compressoror at contactor,w/ power off! Turn on power if fan works normally it's a bad compressor. However if you see a swollen split cap(5 wires to a soup can looking w/ the terminal C,F,and Comp), switch it first and start at square one.
You also need to consider the high pressure switch if its cycling on off on off.

SOURCE: 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 thomastate for ac is showing a flashing snowflake and will not make the ac work how to reset it


The snow flake indicates that the mode is set for cooling, not hearing our both heating and cooling.
There should be two temperatures given by the thermostat, one is the actual room temperature and the other is the temperature setting. The room temperature reading only changes with room temperature change. The thermostat setting temperature changes when the up or down button is pressed.
If your room temperature, say it it's 80° and the temperature is set lower than 80° with a snowflake, the fan should run and start blowing cool/cold air. If you system does not do this, then there is a problem. The problem can be the fan housing cover is not making contact due to the cover not installed properly, nothing will run in this case, no fan. It can be there is no power delivered to the indoor fan, or to the outdoor fan, both these fans must run during thermostat calling for cooling.
The thermostat is not something to be reset as you asked but rather, you check that both fans run and that the outdoor fan makes compressor noise.
Come back with your findings or call a service person. One last try is to shut power to both indoor and outdoor parts of the system and then restore power in attempts to reset the unit or power circuit breakers

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.

Luxpro PSD111 thermostat reading 78 when set to cool at 72. Snowflake blinking and not cooling. Please advise. Thank you.


Usually blinking means you are in a time delay. Obviously not for three hours but... Turn fan to on position and verify your indoor fan is working. If so check outdoor unit and see if it's running. If no indoor fan turn breaker off, and inside the tstat put the red and green wires together and turn breaker back on. If indoor fan runs you have a bad tstat. Good luck!!

Air conditioning not working. Have White-Rodgers thermostat 1F79111, I think. Replaced batteries. Now have flashing signal like an asterisk. What does it mean?


Blinking snowflake means it's on time delay for cooling to come on (usually 5 minute time delay to prevent compressor short cycling). Solid snowflake means cooling is on

It probably has stopped outdoor unit and the blinking is to be done when working anamoni.afto heating and not to bring in cold air flashes the LIGHT as long heated air into the condenser.

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.

I don't know what the hold temp means on my honeywell thermostat


1. You didn't indicate what model of thermostat you have.
2. Hold function on a thermostat with scheduling would mean to hold it at the manual setpoint indefinitely, in other words not following the schedule. 3. I assume the temps you're trying to achieve are C If you have a heat-off-cool switch, I assume it is on the cool position. Most of the honneywell thermostats with a digital display, will indicate a little flame icon when the thermostat is calling for heat, and a littel asterik (snowflake) when calling for cooling. If you don't see the asterik, then you may have a thermostat problem. Have you checked to see if your furnace (air handler) is running? Have you checked to see if your condensing unit outside is running? If they are running, then you have a refrigeration issue.

I have a blinking snowflake icon on my air conditioner, my air will not work. My heater will work fine but the air will not come on


When the snowflake is blinking the thermostat in in a delay mode designed to protect your compressor. If it does not stop blinking in 15min the stat is bad otherwise something is wrong with the AC

On my honeywell rth230b thermostat, sometimes when i try to turn on the a/c, the snowflake will just blink and the a/c will not kick on. why does it do that?


They do that sometimes as a timing feature when going from heat setting the to cool setting or vise/versa. It should not do that when the thermostat is off and then you switch it to cool. Make sure the batteries in the thermostat are fresh. And make sure the thermostat is fully seated on the housing. Also check the wires are fully inserted into the connections on the thermostat housing and the wiring is correct.
