Troubleshooting Problem Symptoms Table 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.
Inspection 1. Measure the resistance between the terminals. 2. The measured resistance is not within specification, the blower resistor must be replaced. (After removing the resistor) Replacement 1.
