Why is my Carrier Air Conditioner compressor operating continuously?
- D
  Danielle HansonAug 15, 2025
  Your Carrier Air Conditioner's compressor might run continuously due to several reasons. It could be a dirty air filter, which requires replacement. The unit might be undersized for the load, suggesting you decrease the load or increase the unit size. Check if the thermostat temperature is set too low and reset it if necessary. A low refrigerant charge could also cause this issue; in that case, locate the leak, repair it, and recharge the system. Another cause might be air in the system, requiring refrigerant recovery, system evacuation, and recharge. Finally, the outdoor coil might be dirty or restricted, so clean the coil or remove any restrictions.

  If the compressor and outdoor fan of your Carrier Air Conditioner won't start, several factors could be responsible. First, there might be a power failure, in which case you should contact your power company. A blown fuse or tripped circuit breaker could also be the cause; replace the fuse or reset the circuit breaker. Other potential causes include a defective contactor, transformer, control relay, or high-pressure/loss-of-charge/low-pressure switch, all of which would need component replacement. Also, insufficient line voltage or incorrect/faulty wiring can prevent starting. Make sure to determine the cause and correct any voltage issues, or check the wiring diagram and rewire correctly. Lastly, check if the thermostat setting is appropriately set.

Why is my Carrier Air Conditioner head pressure too high?
- M
  Molly DavisAug 21, 2025
  Excessive head pressure in your Carrier Air Conditioner can arise from several causes. A dirty air filter can restrict airflow, so replace it. Similarly, dirty indoor or outdoor coils can impede heat exchange; clean them thoroughly. Overcharging the refrigerant can also elevate head pressure, requiring you to recover the excess refrigerant. Furthermore, air in the system can contribute to this issue; recover the refrigerant, evacuate the system, and recharge it. Lastly, restricted indoor or outdoor airflow, or air short-cycling, may be the culprit; identify the cause and correct it.

What causes low suction pressure in Carrier Air Conditioner?
- V
  Vanessa AndersenAug 28, 2025
  Low suction pressure in your Carrier Air Conditioner can stem from several issues. Start by checking the air filter and replace it if it's dirty. A low refrigerant charge could also be the cause, so check for leaks, repair them, and recharge the system. Other potential causes include a restricted metering device or low side, requiring you to remove the source of the restriction. Insufficient coil airflow can also lead to low suction pressure; check the filter and replace it if necessary. If the temperature is too low in the conditioned area, reset the thermostat setting. If the outdoor ambient temperature is below 55°F (13°C), consider installing a low-ambient kit. Lastly, a restricted filter drier can cause this issue, so replace it.

Why won't my Carrier Air Conditioner compressor start, but the condenser fan runs?
- C
  Cindy JohnsonAug 31, 2025
  If your Carrier Air Conditioner's compressor won't start but the condenser fan runs, it could be due to faulty wiring or loose connections in the compressor, so check the wiring and repair or replace it as needed. The compressor motor might be burned out, seized, or have an internal overload open, in which case you should determine the cause and replace the compressor. A defective run capacitor, overload, or PTC (positive temperature coefficient) thermistor could also be responsible, so determine the cause and replace the faulty component. If you have a 3-phase power system, one leg might be dead, requiring you to replace the fuse or reset the circuit breaker and determine the cause. Finally, low input voltage can prevent the compressor from starting, so determine the cause and correct it.

What causes low head pressure in Carrier COMFORT 50ES-A?
- J
  joelmooreSep 7, 2025
  Low head pressure in your Carrier Air Conditioner can be caused by a low refrigerant charge. You should check for leaks, repair them, and recharge the system. Another possible cause is a restriction in the liquid tube, which you'll need to remove.

Why does my Carrier Air Conditioner three-phase scroll compressor has a low pressure differential?
- A
  Amanda KingSep 12, 2025
  If your Carrier Air Conditioner's three-phase scroll compressor has a low-pressure differential, the scroll compressor might be rotating in the wrong direction. Correct this by reversing the 3-phase power leads to the unit.
