Troubleshooting your Roper room air conditioner when it's running but not cooling

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.

Common Roper room air conditioner repair parts

• 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.
