If the lead from the compressor common terminal is burnt and damaged, what should be done?

When the lead from the compressor common terminal is burnt and damaged, the appropriate action is to replace the wire and connector. This is essential because a damaged wire can create unsafe operating conditions, potentially leading to further complications such as electrical shorts, loss of power to the compressor, or even fire hazards.

Replacing the wire and connector ensures that the electrical connection is secure and capable of handling the required current without overheating or failing. It also restores the integrity of the circuit, which is vital for the compressor to operate reliably and safely. This proactive approach helps prevent future issues, ensuring that the system functions optimally and reduces the risk of damage to the compressor or other system components.

Other options, such as ignoring the issue or repairing it with electrical tape, do not address the underlying problem and pose significant risks by failing to ensure a reliable and safe electrical connection. Isolating the compressor may be necessary in certain scenarios but does not rectify the damage and does not address the need for proper functioning.
