What is the proper solution for a malfunctioning sealed relay?

When dealing with a malfunctioning sealed relay, replacing the entire relay is the most effective solution. Sealed relays are designed to be tamper-proof and protect their internal components from environmental factors such as dust and moisture. Because of this design, accessing and repairing the internal components is typically not feasible or practical.

Cleaning the contacts or lubricating the relay is not applicable since sealed relays do not have external access points that allow for such maintenance, and doing so could risk damaging the relay further. Moreover, even if the contacts could be cleaned, if there is any internal failure, the relay would likely continue to malfunction.

Replacing the entire relay ensures that the issue is fully resolved with a new, functioning unit, which will restore proper operation to the electrical system without the complications or risks associated with attempted repairs on a sealed component.
