1. Check the power supply: Ensure that the compressor is receiving power by checking the circuit breaker or fuse that controls it. Make sure the breaker is not tripped or the fuse is not blown.
2. Inspect the wiring: Check the wiring connections to the compressor to ensure they are secure and not damaged. Loose or damaged wires can prevent the compressor from receiving power.
3. Look for error codes: Some Goodman compressors are equipped with an LED indicator light that can display error codes. Refer to the compressor's manual to interpret these codes and identify any potential issues.
4. Test the capacitor: The capacitor helps the compressor start by providing a temporary boost of power. A faulty capacitor can prevent the compressor from starting. You can test the capacitor using a multimeter to measure its capacitance. Replace the capacitor if it is found to be faulty.
5. Clean the condenser coils: Dirty or clogged condenser coils can reduce the compressor's efficiency and prevent it from starting. Clean the coils using a soft brush and vacuum cleaner, taking care not to damage the fins.
6. Overload protection: Some compressors have built-in overload protection that can trip the compressor if it detects a high current draw. Check the compressor for a reset button and press it to reset the overload protection.
7. Refrigerant leak: A low refrigerant charge can cause the compressor to overheat and shut off. Check the refrigerant lines for any signs of leaks, such as oily residue or hissing sounds. If you suspect a leak, it's best to call a qualified HVAC technician for repair.
If you have tried these steps and the compressor still does not start, it's recommended to consult with a certified HVAC technician for further diagnosis and repair.
