How To Tell If An Overload Relay Is Bad. overload relays are devices that protect electric motors from overloads and phase failure. the contacts of a relay can fail due to mechanical wear that is caused by the relay performing thousands or in some cases millions of repeated operations. When the motor is overloaded, it detects this and terminates the power flow, preventing the motor from overheating and winding damage. with motor current flowing, the test button can be used to check whether the relay is working correctly (device/solid. most modern relays have an led to tell you if they are in the active state (on). The contacts of a relay will eventually wear and be unable to make a solid connection. If that light is off and you've got control voltage to the relay or coil terminals (typically a1[line] and a2 [common]) then you can safely assume that relay is bad. if the long start means that the thermal relay is bad and does not start properly, you can listen to the motor to see if there is a buzzing sound. The switching operations take place when the relay opens or closes its contacts. an overload relay is a device that protects an electric motor against overloads and phase failure.
