Easily solve the problem that the Reducer cannot start normally

First, check that the power to the AC relay and thermal protection relay is normal.If there is an abnormal problem, you need to check the power supply and restore the normal power supply of the power supply.
The second generation is to detect whether the winding coil of the AC relay is damaged or worn, and then check the magnet for rust.If so, remove the rust from the magnets during actual maintenance.If the coil is damaged, it must be replaced in time.
The third is to detect whether the winding of the AC relay has a short circuit problem.If there is no short circuit, continue to test whether the wiring contact of the thermal protection relay is unobstructed.If there is a short, repair the AC relay directly so that its contacts can make good contact.
