Why is my Rheem RA1460AJ1NA Air Conditioner not cooling properly?
- J
  Joshua RodriguezSep 8, 2025
  If your Rheem Air Conditioner isn't cooling enough, several factors could be responsible. The unit might be improperly sized, so recalculate the load. There could be improper indoor airflow; it should be about 400 CFM per ton. The refrigerant charge might be incorrect, so charge it according to the procedure on the unit's service panel. Air, noncondensibles, or moisture in the system can also cause this, in which case you should recover the refrigerant, evacuate, and recharge, adding a filter drier. Finally, a bad ID TXV could be the culprit, requiring replacement.

What causes gurgling noise in Rheem Air Conditioner?
- M
  Madeline HansenSep 7, 2025
  A gurgling or pulsing noise at the expansion device or liquid line in your Rheem Air Conditioner usually indicates air or noncondensibles in the system. To fix this, recover the refrigerant, evacuate the system, and recharge it.

  Insufficient cooling in your Rheem Air Conditioner can stem from several issues. The unit might be improperly sized, requiring a recalculation of the load. There could be improper indoor airflow; check to ensure it's approximately 400 CFM per ton. An incorrect refrigerant charge is another possibility; charge the system per the procedure attached to the unit service panel. Also, air, noncondensibles, or moisture in the system can cause this problem, requiring refrigerant recovery, evacuation, and recharge, along with the addition of a filter drier. Finally, a faulty ID TXV could be the culprit, necessitating replacement.

Why are the head and vapor pressures fluctuating in my Rheem RA1460AJ1NA Air Conditioner?
- T
  Terrance KelleySep 4, 2025
  Fluctuating head and vapor pressures in your Rheem Air Conditioner can be due to TXV hunting. Check the TXV bulb clamp and the air distribution on the coil, and consider replacing the TXV. Another cause might be air or noncondensibles in the system, requiring refrigerant recovery, evacuation, and recharge.

What does low head and high vapor pressures mean for Rheem RA1460AJ1NA?
- C
  Cody WilliamsSep 3, 2025
  Low head pressure coupled with high vapor pressures in your Rheem Air Conditioner can point to a bad TXV, which requires replacement. Another potential cause is a bad compressor, which would also need replacing.

- R
  Robert WarrenAug 31, 2025
  High vapor pressure in your Rheem Air Conditioner can be caused by an excessive load, so recheck the load calculation. It may also be due to a defective compressor, which would require replacement.

Why is my Rheem RA1460AJ1NA Air Conditioner's indoor coil iced?
- A
  Abigail RodriguezAug 30, 2025
  An iced indoor coil, accompanied by low vapor and a cool compressor in your Rheem Air Conditioner, can be attributed to several factors. Low indoor airflow could be the culprit; increase the blower speed or reduce restrictions, and replace the air filter. If you're operating below 65°F outdoors, consider adding a Low Ambient Kit. Moisture in the system can also lead to this issue, requiring refrigerant recovery, evacuation, recharge, and the addition of a filter drier. Lastly, a closed ID circuit might be the cause, necessitating repair or replacement of the ID coil.

Why does my Rheem Air Conditioner have high head pressure in cooling mode?
- B
  Brad BrennanAug 29, 2025
  High head pressure in cooling mode for your Rheem Air Conditioner can result from a few issues. The outdoor coil might be dirty, so cleaning it is recommended. Refrigerant overcharge could also be the problem, requiring a correction of the system charge. If the outdoor fan isn't running, it needs repair or replacement. Finally, air or noncondensibles in the system could be the cause, requiring refrigerant recovery, evacuation, and recharge.

What causes Rheem RA1460AJ1NA outdoor fan to run but compressor not?
- F
  Frank CobbAug 27, 2025
  If the outdoor fan of your Rheem Air Conditioner is running but the compressor isn't, it could be due to several reasons. A defective run or start capacitor may be the cause, requiring replacement. The contactor could also be defective and need replacement. Check for correct voltage at the compressor and ensure all connections are tight, as a loose connection could be the problem. The compressor might be stuck, grounded, have an open motor winding, or an open internal overload; wait at least 3 hours for the overload to reset, and if it remains open, replace the compressor. A low-voltage condition could also be the cause, in which case you should add start kit components.
