It requires surgery to remove the beeper :) seriously, find a local nerd to go in, not hard to do, and yank out the little piezo buzzer. I've had customer that wanted the same, factory said sorry no dice.

Can you turn it on with the pad on the unit?

If you are a technician, then the first thing to do is to see what the actual fault that caused the lock out is. This is found on the control board in the outdoor unit. There should be LED's on the board that will give a trouble code. The fault MUST be corrected or the logic in the board will just keep locking the system out. The issue may be due to a failed component, low charge, faulty sensors, power outages, etc. It is really difficult for anyone to give a specific fix without looking at it to see what the fault is. I would definitely NOT recommend attempting a fix if you are not a trained technician due to the high voltage hazards and the specialized tools needed to work on the system. If you are a homeowner, I would recommend recycling power at the indoor and outdoor unit, then if it faults out a technician. Leave the power off for 5-15 minutes to allow the system to completely de-energize, then turn it back on. Hope this helps.

Reason for water leaking.
1. Filter block. 2. Cooling coil block. 3. Alignment of indoor a/c unit is sloping downwards. 4. Drain pan block. It's advisable to service your unit first.

Try cleaning it and spray with an antibacterial spray. When the unit is running in cool mode it condensates and creates a moist environment inside the ac perfect for mold growth, some units have a coil dry mode which runs the fan to dry out the system after use.
