This problem is outdoor unit issue. Blinking 4 times in carrier highwall unit means Compressor drive malfunction. Possible cause are the following:- Stuck up or grounded compressor.- Magnetic contractor in outdoor unit is defective or indoor unit relay supplying outdoor unit is defective.- No power supply going to outdoor unit

Hi, kindly provide the full model name of the cassette unit as written on the name plate. Can you tell us which LED green light is blinking 3 times?

Plz mention it is split or cassette type unit... Tnq

You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. If that dosn't work then you should contact a professional.

Switch OFF the circuit breaker of ac, after 5 seconds. Switched ON the circuit breaker. If this will appear again try to check the wiring connection of ac.
