A:AnswerDo not use an extension cord. If your air conditioner is too far from the power outlet, move your air conditioner or have an electrician install a plug closer to your air conditioner.
A:AnswerI had the same issue until I realized I needed to press the reset button on the plug before it will turn on the first time. Hope that's your issue.
A:AnswerWhen the drain tray is full, your air conditioner beeps eight times, P1 appears on the control panel display, and your air conditioner stops. The motor continues to run. Carefully move your air conditioner to a drain location, then remove the bottom drain plug and let the water drain away. If you don’t have a drain, use a cookie with sides or a shallow dish.
