What should you check if a motor is unresponsive when the relay is activated?

When a motor is unresponsive despite the relay being activated, the first thing to check is the power supply. The motor requires a sufficient voltage and current to operate. If the power supply is faulty or not delivering the appropriate electrical energy, the motor will not function even if all other components, such as the relay, are in good working order.

A power supply issue could stem from numerous factors, such as a blown fuse, tripped circuit breaker, or a damaged power cord, all of which can prevent the motor from receiving the necessary power. Ensuring that the power supply is intact and functioning properly is crucial before moving on to other components like the relay contacts or wiring connections. This systematic approach helps isolate the problem efficiently by establishing that the motor has access to power.
