Carrier 49 is a compressor overcurrent fault, the local code. It elevates to fault 95 after 5 occurrences. Reset time is 6 minutes. Table 6 says to use the fault 95 checks. It is not brownout 46, and it is not the 2-hour lockout 95. Count 4 short flashes and 9 long flashes.
Likely causes
- The service manual points code 49 at the fault 95 cause list
- Compressor operating outside its allowed envelope, or high superheat
- Incoming power supply voltage, loose power leads, or a phase imbalance
- Outdoor airflow too low, refrigerant overcharge, inverter damage, or compressor internal damage
Safe checks for 49
- Count 4 short flashes and 9 long flashes. With power off, look at the outdoor coil for ice or debris. That is the airflow line on the fault 95 table this code points to
- Technicianfollow fault 95. Charge, winding resistance, voltage against the rating plate, and inverter or compressor replacement are that table
Capacitors can hold a charge after the power is off. Safety terms.
When to call a pro
Call a licensed HVAC technician if 49 repeats. Five occurrences become the 2-hour lockout 95.
