Possible Causes

Incorrect piping connection between indoor and outdoor ports, Closed service valves, Severely low refrigerant charge, Blocked expansion valve

How to Fix / Troubleshooting

Warning: Refrigerant system work must be done by licensed personnel. Homeowners should limit actions to visual checks.

Basic checks:

  • 1. Confirm service valves: Ensure the outdoor liquid and gas service valves are fully open (remove caps and check with hex key).
  • 2. Verify piping connections: Compare actual piping to installation labels; each indoor should connect to the correct outdoor port.
  • 3. Look for obvious leaks: Oil stains on flare joints or brazed connections indicate refrigerant leaks. Do not attempt to tighten flares under pressure.

If H32 remains, a technician must check pressures, weigh in correct Panasonic-specified refrigerant charge, and verify expansion valve operation.
