5 Things to Check if an Electric Motor Won't Run

If you have an electric motor that does not want to run it not only is an annoyance, but it is likely harming your company's production. There are several reasons a motor may fail to start but to get to the root cause quickly be sure to check these common problems. If it is found that one of these issues is the problem be sure to get in touch with a professional electric motor repair technician to get the machine back up and running. Of course, if you can't diagnose the issue based on these common problems, the same repair technician will be able to do so.

Blown Fuse

One of the most common problems that prevent electric motors from turning on or operating at all are blown fuses. If a fuse blows it will need to be replaced with a fuse of the same amperage and the breaker will need to be reset. A fuse may blow due to excessive current draw, so if it happens repeatedly the motor may need additional repair.

Broken Wiring

If the wiring that passes current through the motor is loose, of the wrong gauge or is broken the motor may not start. To see if this is the problem be sure to look over all of the wiring in the starting circuit of the motor using an owner's manual that has motor diagrams.

Corroded Control Switch Contacts

A burnt, dirty or corroded control switch can prevent the proper flow of electricity through the motor. Check the control switch contacts if a motor does not start. If they are found to be dirty they can often times be cleaned and won't necessarily need to be replaced.

Bad Starter Coil

If the starter coil has gone bad or if it was replaced with a non-original part it may prevent the motor from starting. Double check that the correct coil is being used for this particular electric motor.

Failed Starting Capacitor

Not all motors use a starting capacitor, but if your motor does you will want to check to ensure there is resistance. If there is zero or low resistance in the capacitor it will most likely need to be replaced.
