What to do if my Rheem RRPL-B's condenser fan runs, but the compressor doesn’t?
- S
  Sherry WalterAug 2, 2025
  If the condenser fan in your Rheem Heat Pump runs but the compressor doesn’t, there are several potential causes. If it's a single-phase system, the run or start capacitor might have failed, in which case you should replace it. Similarly, the start relay could be defective (single phase only) and needs replacement. Check for correct voltage at the compressor and tighten all connections, as a loose connection could be the issue. If the compressor is stuck, grounded, or has an open motor winding or internal overload, wait at least 2 hours for the overload to reset; if it remains open, replace the compressor. A low voltage condition might also be the reason, in which case you should add start kit components.

How to troubleshoot insufficient cooling in my Rheem RRPL-B Heat Pump?
- S
  sandrafrancisAug 11, 2025
  If your Rheem Heat Pump is providing insufficient cooling, several factors could be responsible. First, the unit might be improperly sized, so recalculate the load. Check for proper airflow, which should be approximately 400 CFM per ton. The refrigerant charge might be incorrect; charge it per the procedure attached to the unit service panel. Air, non-condensibles, or moisture in the system could also be the cause; in this case, recover the refrigerant, evacuate and recharge the system, and add a filter drier. Finally, ensure the voltage is correct; at the compressor terminals, voltage must be within 10% of the rating plate volts when the unit is operating.

Why my Rheem RRPL-B unit will not run?

  Taylor BrownAug 22, 2025
  If your Rheem Heat Pump unit won't run, several factors could be the cause. First, ensure that there is correct voltage at the compressor contactor in the control box, as power might be off or there could be a loose electrical connection. Check and replace any blown fuses. The thermostat might be out of calibration, so try resetting it. A failed contactor could also be the culprit; check for 24 volts at the contactor coil and replace it if the contacts are open. Also, the transformer might be defective, so inspect the wiring and replace the transformer if needed. If provided, the high-pressure control might be open, so reset it, keeping in mind that it opens at 610 PSIG. Finally, inspect and replace the thermostat wiring if the interconnecting low voltage wiring is damaged.
