Home / What to do if a relay protection device malfunctions

This guide provides a step-by-step approach to relay circuit troubleshooting, covering everything from identifying relay failure analysis to relay coil testing and addressing relay contact problems. In this blog, we review typical failures witnessed with these relays and the best possible diagnostic strategies to ensure they serve safely. General Purpose Relays are multipurpose and commonly found in several areas like automotive industry or home automation systems among others. If the contact does not operate (conduct electricity) even though voltage is applied to the coil, it is possible that the relay drive system (coil) is defective or the contact that opens and closes the load is defective.
