How do you diagnose a bad AC pump?
Some of the signs of a bad A/C compressor are as follows.
- A Lack of Hot Air Being Released Outside.
- Loud or Strange Noises From the Unit.
- Failure of the Compressor to Turn On.
- Circuit Breaker Tripping.
- Leaks Around the Air Conditioning Unit.
- Warm Air Instead of Cool Air Being Delivered to the House.
- Reduced Airflow.
How much does it cost to fix AC wires?
Across the nation, the average cost for central air conditioning repair is between $50-$100 for a service fee and $300 if you need both labor and parts.
What causes an AC compressor to short to ground?
When a compressor has a short-to-ground, it is likely caused by damage to the insulation within the compressor itself. Damage to the insulation is likely caused by acid within the system. Acid in the system can result from improper system evacuation or the presence of air/moisture in the system.
What does the ground wire on a pump read?
The ground wire from the pump will read low resistance to ground. The other 2 wires are the pump leads. Neither of the pump leads should read much continuity to ground, but will register a hundred ohms or so between each wire. That is the motor winding. The pump is AC so you cannot make it run backwards by reversing the leads.
What kind of wire to use for a pump?
Use an ohmmeter, and check for continuity (low resistance) between the ground of the pressure switch and each pump wire. The ground wire from the pump will read low resistance to ground. The other 2 wires are the pump leads.

What are the three wires on a submersible pump?
A continuity tester MIGHT tell you which two leads are for the motor itself, but the third wire could be a ground or a capacitor feed. We cannot tell which without seeing a wiring diagram for the motor or the control box. Re: wiring submersible pump – what wires are what ?
