Before replacing or repairing air conditioning components,
first determine if the malfunction is due to the refrigerant charge, air
flow or compressor.
Use the table below to help you find the cause of the
problem. The numbers indicate the priority of the likely cause of the
problem. Check each part in order. If necessary, replace these parts.
After correcting the malfunction, check the complete system to ensure that performance is satisfactory.
