We downloaded a programme called Snowflake and the Macbook pro froze and since we are not able to get past a snowflake screen since rebooting. We have tried everything can you advice how to troublshoot this problem?

Disconnect at the breaker for 30 minutes to do a forced Reset. It is my view that is is the AC appliance being switched, not the thermostat itself.

Hello, the snowflake flashing is a (supposed to be) 5 minute delay to prevent short cycling of the compressor. This delay can sometimes get stuck thus requiring replacement. To test , remove top of thermostat to where you can identify wires and terminals. Have someone stand near the ac unit for this test, and then take a wire or paperclip and briefly touch Rc to Y. This should start the outdoor unit. R to G will start the indoor fan

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

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

The flashing snowflake means it is in the cooling mode, but is waiting for itself to 'time out' after a call for cooling. It should be about a 5 minute delay then should come on automatically. At that poing, the flashing snowflake becomes steady.

Try it one more time and set the timer on your smart-phone to ten minutes before you touch it again. If that time elapses and no cooling and it is still flashing there's possibly a problem in the thermostat that will necissitate replacement.

The snowflake indicates cold or snow. Usually the snowflake will show up when it gets below a certain temp outside. I have cousins by the last name Soldano.........

a flashing snowflake indicates a time delay in cooling and a flashing flame indicates heat delay and both are normal

flashing snowflake normally means it is in a time delay. give it five minutes and see if it continues.

That is a Time delay normal to keep the condensing unit from turning of and on to fast really save the life of the equipment

the flashing snowflake is it telling you its in % min delay if it doesnt stop flashing within 5min it may be a bad tstat. if it goes solid and the unit is still not working its probably not the stat
