Why Airwell Heat Pump compressor operates but has no capacity?
If your Airwell Heat Pump compressor operates but there's no capacity, it could be due to an EEV problem, refrigerant leakage, or a blockage in the indoor or outdoor coil. You should check the EEV and refrigeration system. Clean the filters and remove any blockage from the indoor coil. Remove any blockages from the outdoor coil and prevent air bypass.
What to do if there's water leakage from my Airwell Heat Pump indoor unit?
If you notice water leakage from the indoor unit of your Airwell Heat Pump, it's likely that the drainage tube is blocked. To resolve this, check and open the drainage tube.
Why does my Airwell Heat Pump compressor stop during operation?
If the Airwell Heat Pump compressor stops during operation, it could be due to electronic control issues or refrigerant leakage. You should check the diagnostics and the refrigeration system to identify the problem.
What causes my Airwell Heat Pump to stop suddenly?
If the Airwell Heat Pump suddenly stops during operation, it could be due to EMC interference. You should check for EMC problems.
Why doesn't the indoor fan start on my Airwell Heat Pump?
If the Airwell Heat Pump indoor fan doesn't start, but the louvers are open and the Green LED is ON, there could be several reasons: * The unit is in heat mode and the coil is not yet warm: Change to cool mode. * The outdoor unit is in the opposite mode: Change the operation mode. * There's a problem with the controller or capacitor: Change to high speed and check the power supply to the motor. If the power supply is OK, replace the capacitor; if not, replace the controller.
Why is my Airwell Heat Pump working in the wrong mode?
If the Airwell Heat Pump unit operates in the wrong mode (e.g., cooling instead of heating), it could be due to electronics or RV problems. In this case, you should check the RV.
Why is the Airwell Heat Pump compressor motor noisy with no suction?
If the Airwell Heat Pump's compressor motor is generating noise but no suction is occurring, the phase order to the compressor might be incorrect. Check the compressor phase order to resolve this issue.
Why does my Airwell Heat Pump's indoor fan run when OFF?
If the Airwell Heat Pump indoor fan works when the unit is OFF, and the fan speed cannot be adjusted with the remote control, it indicates a controller problem. Replace the controller to fix this.
Why is the display off on my Airwell Heat Pump outdoor unit?
If the outdoor unit display board and LEDs on your Airwell Heat Pump are off, it could be due to several reasons: * No power supply: Check the connections and wiring on the main terminal and repair if needed. * PFC Chock coil: Check the PFC Chock coil. * Burnt fuse: Check the 20A fuse on the filter.
What to do if my Airwell Heat Pump doesn't respond to the remote?
If the indoor unit of your Airwell Heat Pump does not respond to the remote control, it could be that the remote control message isn't reaching the unit. You should check the remote control batteries. If they are OK, check the display and display wiring. If that's OK, replace the display PCB. If it's still not working, replace the controller.
