Cross Flow Fan Assembly
★★★★★

Part #5901A20050A
This black cross flow fan, also known as an evaporator fan blade, circulates air across the evaporator or condenser coils in your air conditioner to help cool the room. It is typically located within the unit. To identify a broken cross flow fan assembly, look for a few signs. First, you may notice reduced or no airflow from the air conditioner. Second, listen for unusual noises like rattling, grinding, or squealing coming from the fan. Finally, inspect the fan blades and motor for visible damage such as cracks, bent blades, or signs of wear and tear. To replace the fan, detach the front grille and remove the control box assembly and air guide assembly from the unit. Loosen the screw on the cross flow fan and the screws securing the indoor motor and earth wire. Remove the supports on both sides of the fan and then pull out the fan from the air guide. This replacement part is sourced directly from the original equipment manufacturer and is sold individually.

Part #4280A20004M
Unusual noise from an indoor blower can be caused by a worn blower wheel bearing. This replacement bearing provides a smooth support point that allows the wheel to rotate while moving air across the room. Inspect the wheel for cracks, dirt, rubbing marks, or looseness, since these problems can produce similar sounds. Turn off the unit at the breaker and verify that power is disconnected before opening the cabinet. Keep track of screws, clips, and wheel position during removal. Install the bearing in the correct direction, avoid forcing it into place, and spin the wheel by hand to check for rubbing before reassembly.

David - For model number LP123CD3A
June 17, 2024
I have a CH03 code coming up
Chris Boyle Profile
Hello David, thank you for contacting us. The error code CH03 is displayed when the unit has detected that there is no refrigerant. We would recommend checking that there is enough refrigerant in the system. If the issue persists, then you may need to check the compressor, part number PS3536117, to solve the problem. Glad to be of help!
