Question about Carrier Heating & Cooling
SOURCE: Carrier Aircon WCARG010EE 1 HP
You must check if there is power to the fan to confirm if there is failure of the fan motor. Since the FR display indicates there is possibility that the power is initiating.
If the remote unit is not powered from the main unit then it is possible that the main control section must be checked for failure in the control unit.
Check for faulty wiring to the remote unit-or a break in the wiring from the main unit. Check the received voltages on the remote unit.

According to the Owners Manual, E4 is a fault code that requires service by an authorized Carrier Serviceman. No other explanation for it was given.
Sorry I could be of more help.

I got the same problem in Samsung aircon. The unit I purchsed died slowly. After that Samsung replaced it with the one have the same problem. They are swearing that the green light blinking problem as a normal function and refusing to fix. Their user manual says it is a problem. I think the affected consumers should join hands to take legal action against this scam.
