- You Have a Hard Time Getting Your AC to Start.
- Your AC Stops Blowing Cold Air.
- Circuit Breaker Problems.
- Diminished Airflow.
How can I tell if my compressor pressure is normal?
The readings on the a/c manifold gauges should show normal pressures at this point. While charging the system with refrigerant, monitor the variable voltage signal to the compressor. Some systems will display the compressor voltage/amperage applied on a scan tool.
What kind of test is needed for air conditioner compressor?
One other test with the mechanical system will be an oil test. Required for this function is a special kit. With the oil test kit, take a sample of the compressor oil. Then it is sent to a lab to determine that the oil contains all-natural properties required of refrigerant oil.
What’s the best way to repair an A / C compressor?
The best way to begin any A/C repair is with a thorough A/C inspection of the components since the problem can stem from a number of things. After checking components like the belts, the hoses and the related connections, the next step is a visual inspection of the A/C compressor.
How to diagnose an air conditioner problem?
When diagnosing an air conditioning issue, it’s easiest to begin at the compressor: With the engine running turn the A/C on max cool, set fans high, and make sure that the clutch is engaging on the compressor. Note: this is not the pulley, but the center piece that engages the pulley to the compressor shaft.

What to do if your compressor is inefficient?
Figure 1 is a service checklist for an inefficient compressor with bad valves or worn rings. This checklist is for a compressor that is still cooling but is showing signs of inefficiency. ( Note: The severity of the problem will cause the checklist to change.) Low amp draw.
Is it possible to troubleshoot an air conditioner compressor?
Air Conditioner Compressor Troubleshooting can be challenging. The average compressor in many residential condensing units is hermetically sealed compressors. Furthermore, the only visible working parts on the compressor are the electrical connections and the copper discharge and suction lines.
