Roper Room air conditioner Parts — Browse All Models

If your Roper room air conditioner's compressor and fans are running but the air conditioner isn't cooling, possible causes include a failed compressor or the lack of refrigerant due to a leak in the sealed system. If the compressor isn't running but the fans work, the start relay or compressor might have failed. A defective electronic control board or control thermostat could prevent the window air conditioner from cooling. See the repairs listed below for help with correcting this problem.

• Electronic control board. The electronic control board in your Roper air conditioner detects temperatures and controls the compressor and fans to cool the room to the set temperature.
• Blower fan motor. The blower fan motor spins the blower fan blade to move air through the evaporator fins and into the room.
• Ambient thermistor. The ambient thermistor detects room temperature and sends the temperature signal to the electronic control board.
