What to do if my RIDGID R4840 Sander motor stalls and blows fuses?
If your RIDGID Sander motor stalls, leading to blown fuses or tripped circuit breakers, there are several potential causes. The motor relay might not be operating correctly, and you should consult an Authorized Service Center to have it replaced by a qualified technician. Also, the voltage may be too low, in which case you should request a voltage check by a qualified electrician. Ensure that you have the correct fuses or circuit breakers installed in your power line.
Why does my RIDGID Sander motor lack power?
If your RIDGID Sander motor fails to develop full power, starts slowly, or doesn't reach full speed, it might be due to a circuit overloaded with lights, appliances, and other motors. Avoid using the sander on heavily loaded circuits. It could also be due to general overloading of power company facilities, in which case you should request a voltage check by a qualified electrician. The motor relay might also not be operating; consult an Authorized Service Center to have the relay replaced by a qualified service technician.
Why does my RIDGID R4840 Sander keep tripping the circuit breaker?
If your RIDGID Sander experiences frequent opening of the fuse or circuit breaker, it could be due to the motor being overloaded; try feeding the workpiece slower.

If the relay is not operating correctly, consult an Authorized Service Center to have it replaced by a qualified service technician.
How to fix a RIDGID Sander that won't start?
