Usually a flashing snowflake means you are in a time delay for cooling. If the snowflake becomes solid, cooling should start. If it never stops flashing, possibly it's bad. Turn power off to air handler, remove stat and put red green and yellow together and turn power back on. If indoor AND outdoor work and cooling begins the tstat is definitely bad.
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
By unit, do you mean the thermostat? And if so, do you mean the whole face is flashing, or just a heat or cool symbol? And if your talking about the heating/cooling unit, are you talking about a flash on the board?
A thermostat face that is flashing is usually batteries.
A symbol that is flashing on a thermostat indicates a call and is in a delay. There will be a 5 minute delay on calls if the call has been short cycled, powered off and on, etc.
If the symbol continues to flash for an extended amount of time, then the problem is in the furnace, air handler, etc.
If the system is working, but flashing, then it could be the programming of the thermostat.
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.
It means the trailer is too warm for the thermostat to work - above 90 degrees inside. Take some ice and put in ziplock bag - place over thermostat and cool it down. Unit will start working when thermostat senses it is BELOW 90 degrees. FAULTY DESIGN.
Unfortunately no, this is one of three things. 1. Compressor is worn and is starting to pull to many amps to operate. Can possibly be fixed by putting a hard start kit on the unit, but will have to be done by a technician. 2. Compressor has an internal short and will have to be replaced. 3. Fuses bad or under sized. Max fuse size is stated on information plate on outside unit.
Sorry to hear about your troubles and hope you can get it fixed soon!
a little more information would be helpful.
what is the model and manufacturer of the refrigerator?
there may be a legend to let you know what 'flashing 3 code' means.
a few things you may want to check are:
1. if there are fans in the refrigerator make sure there is sufficient air flow space
2. be sure your condenser coils are clean and free of dust and/or grease buildup
3.see if your evaporator is freezing up
4.be sure the thermostat is calling for cooling and your compressor is running.
Do you hear the compressor running? Just because the thermostat is on high doesn't mean it is calling for cool. Do you hear a click or snap when the thermostat is turned from low to high? Possibilities are: Thermostat, compressor start relay, overload, gas leaked out, compressor failed. eric
