After a fusible link has tripped, what should a technician do?

When a fusible link has tripped, it indicates that it has acted as a safety mechanism to prevent overheating or a potential fire hazard in the system. The correct action is to replace the tripped fusible link with a new one because these links are designed to melt at a specific temperature, and once they have melted, they cannot be reused.

Replacing the damaged link ensures that the safety function of the system is restored and that it can operate effectively without the risk of overheating in the future. Additionally, after replacing the fusible link, it’s essential to investigate further why it tripped in the first place, as there may be underlying issues that need addressing to prevent recurrence. This ongoing maintenance contributes to the overall safety and efficiency of the HVACR system.
