To Next PageTo Next PageWhy are the registers sweating in my Rheem Air Conditioner system?
If the registers in your Rheem Air Conditioner system are sweating, it's likely due to low indoor airflow. Try increasing the blower speed or reducing any restrictions in the airflow. Replacing the air filter can also help.
How to troubleshoot a Rheem RA1336AJ1NA that will not run?
If your Rheem Air Conditioner unit won't run, several factors could be the cause. It could be due to a power outage or loose electrical connection, so check the voltage at the line voltage connections. The thermostat might be out of calibration, so try resetting it. A blown fuse or tripped breaker can also prevent the unit from running, so replace the fuses or reset the breaker. Other potential issues include a defective transformer (check the wiring and replace if necessary), an open high-pressure control (reset it), an open low-pressure control, a defective control board (check diagnostic codes), or miswiring of communications (check communication wiring).
Why is my Rheem RA1336AJ1NA Air Conditioner not cooling properly?
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 to do if the Rheem RA1336AJ1NA outdoor fan runs but the compressor doesn't?
If the outdoor fan of your Rheem Air Conditioner is running but the compressor isn't, the issue could stem from a defective run or start capacitor, which would need replacement. Alternatively, the contactor might be defective and also require replacement. Check for correct voltage at the compressor and tighten all connections to address any loose connections. If the compressor is stuck, grounded, or has an open motor winding or internal overload, wait at least 3 hours for the overload to reset; if it remains open, replace the compressor. A low-voltage condition could also be the cause, and adding start kit components might resolve the issue.
Why does my Rheem RA1336AJ1NA Air Conditioner compressor short cycle?
If the compressor in your Rheem Air Conditioner is short cycling, it could be due to incorrect voltage. Ensure the voltage at the compressor terminals is within ± 10% of the nameplate marking when the unit is operating. Another cause could be a defective overload protector, which would need to be replaced. Also, refrigerant undercharge can cause short cycling, so add refrigerant as needed.
What causes high head pressure with normal vapor pressure in a Rheem RA1336AJ1NA Air Conditioner?
If your Rheem Air Conditioner shows high head pressure with high or normal vapor pressure in cooling mode, the outdoor coil might be dirty, requiring cleaning. Alternatively, the system could be overcharged with refrigerant, necessitating a correction of the system charge. Another possibility is that the outdoor fan isn't running, which means it needs repair or replacement. Lastly, air or noncondensibles in the system can cause this issue, requiring refrigerant recovery, evacuation, and recharge.
Why is the indoor coil of my Rheem RA1336AJ1NA Air Conditioner iced, with low vapor pressure?
If you notice low vapor pressure, a cool compressor, and an iced indoor coil in your Rheem Air Conditioner, it could be due to low indoor airflow. Try increasing the blower speed or reducing restrictions, and replace the air filter. If you're operating the unit below 65°F outdoors, consider adding a Low Ambient Kit. Moisture in the system can also cause this issue, so recover the refrigerant, evacuate, recharge, and add a filter drier. Finally, a closed ID circuit could be the problem, requiring repair or replacement of the ID coil.
What causes fluctuating head and vapor pressures in a Rheem RA1336AJ1NA?
If your Rheem Air Conditioner is experiencing fluctuating head and vapor pressures, it could be due to TXV hunting. Check the TXV bulb clamp and air distribution on the coil; consider replacing the TXV. Another potential cause is air or noncondensibles in the system, which requires recovering the refrigerant, evacuating, and recharging.
What does it mean when my Rheem RA1336AJ1NA has high head and low vapor pressures?
If your Rheem Air Conditioner has high head pressure but low vapor pressures, there might be a restriction in the liquid line, expansion device, or filter drier. Remove or replace the defective component. Another cause could be a bad TXV, which would need to be replaced.
What could cause high vapor pressure in my Rheem RA1336AJ1NA Air Conditioner?
If your Rheem Air Conditioner is showing high vapor pressure, it could be due to an excessive load, so recheck the load calculation. Alternatively, the compressor might be defective and need replacement.
