What to do if my Rheem Heat Pump unit will not run?
- K
  Kristy GlennAug 17, 2025
  If your Rheem Heat Pump unit isn't running, several factors could be at play. Start by checking for correct voltage at the line voltage connections in the condensing unit. Also, make sure that the thermostat isn't out of calibration or set too high. Inspect the control board diagnostic codes. Look for blown fuses or tripped breakers and replace/reset them as needed. Check the transformer wiring and replace the transformer if it's defective. Reset the high-pressure control if it's open, and also refer to the high head pressure remedy. Do the same for the low-pressure control. Finally, verify the communication wiring if there's miswiring or the communication light is continuously on.

Why is my Rheem RA1760AJ2CB Heat Pump compressor short cycling?
- T
  Tyrone CarterAug 20, 2025
  If your Rheem Heat Pump's compressor is short cycling, it could be due to several reasons. First, check the voltage at the compressor terminals to ensure it's within ±10% of the nameplate marking when the unit is operating. A defective overload protector could also be the culprit, so consider replacing it. Finally, refrigerant undercharge can cause short cycling, so adding refrigerant may solve the issue.

What causes insufficient cooling in my Rheem RA1760AJ2CB Heat Pump?
- D
  Derek LevyAug 23, 2025
  Insufficient cooling in your Rheem Heat Pump can stem from several causes. The unit might be improperly sized, requiring a recalculation of the load. Improper indoor airflow could be the issue; it should be approximately 400 CFM per ton. An incorrect refrigerant charge can also lead to this problem, so charge the unit per the procedure attached to the service panel. Air, non-condensables, or moisture in the system necessitate recovering the refrigerant, evacuating, and recharging, along with adding a filter drier. A bad ID could also be the cause, in which case it should be replaced.

Why is my Rheem RA1760AJ2CB's outdoor fan running, but the compressor isn't?
- T
  Todd KingAug 26, 2025
  If the outdoor fan is running but the compressor isn't in your Rheem Heat Pump, it could be due to a defective run or start capacitor, which would need replacement. Another possibility is a defective contactor, which should also be replaced. Check for correct voltage at the compressor and ensure all connections are secure. If the compressor is stuck, grounded, has an open motor winding, or an open internal overload, wait at least 3 hours for the overload to reset; if it remains open, replace the compressor. A low-voltage condition might also be the cause, in which case you should add start kit components.

What causes high head and high or normal vapor pressure in cooling mode on my Rheem RA1760AJ2CB?
- D
  donaldconleyAug 28, 2025
  High head pressure along with high or normal vapor pressure in cooling mode on your Rheem Heat Pump can be attributed to a dirty outdoor coil, which needs cleaning. It could also be due to refrigerant overcharge, requiring a correction of the system charge. If the outdoor fan isn't running, repair or replace it. The issue might also arise from air or non-condensables in the system, necessitating refrigerant recovery, evacuation, and recharge.

What causes low vapor, cool compressor, and iced indoor coil in my Rheem RA1760AJ2CB Heat Pump?
- F
  Frances ButlerAug 31, 2025
  A low vapor pressure, cool compressor, and iced indoor coil in your Rheem Heat Pump can be caused by low indoor airflow. Increase the blower speed or reduce restrictions and replace the air filter. Operating below 65°F outdoors can also cause this issue, so add a Low Ambient Kit. Moisture in the system requires refrigerant recovery, evacuation, recharge, and the addition of a filter drier. Finally, a closed ID circuit necessitates repairing or replacing the ID coil.

Why do the registers sweat on my Rheem Heat Pump?
- S
  Stephen MartinezSep 2, 2025
  Registers sweat on your Rheem Heat Pump due to low indoor airflow. To resolve this, increase the speed of the blower or reduce any restrictions. Also, replace the air filter.

What causes fluctuating head and vapor pressures in my Rheem RA1760AJ2CB?
- J
  Jessica ThomasSep 5, 2025
  Fluctuating head and vapor pressures in your Rheem Heat Pump can occur if the = is hunting. Check the thermistor to vapor line connection. Air or non-condensibles in the system can also cause this issue, requiring refrigerant recovery, evacuation, and recharge.

What causes high vapor pressure in my Rheem Heat Pump?
- P
  pauljohnsonSep 8, 2025
  High vapor pressure in your Rheem Heat Pump can be caused by an excessive load. Recheck the load calculation. A defective compressor can also be the problem, requiring replacement.

What causes high head and low vapor pressures in my Rheem RA1760AJ2CB Heat Pump?
- M
  Molly DavisSep 12, 2025
  High head pressure and low vapor pressures in your Rheem Heat Pump can be caused by a restriction in the liquid line, expansion device, or filter drier. To resolve this, remove or replace the defective component. A bad = can also cause this issue; verify the thermistor and pressure transducer connection and operation.
