Panasonic Air Conditioner Repair Guide: Air conditioner not cooling (C116 filter capacitor leakage)

Analysis and Detection: After inspection, it was found that the C116 filter capacitor on the circuit board was leaking.

Repair Method: Replace the C116 filter capacitor to eliminate the fault.

Warm Reminder: The control method of this air conditioner involves a transformer converting 220V AC power into 12V AC power. After rectification and filtering, +12V DC power is generated. The +12V DC power then passes through a 7805 voltage regulator to produce a +5V regulated power supply. C109, C116, C117, C118, C119, C120, and C121 are filter capacitors used to enhance the controller's ability to resist interference.
