Right angle grinders are not very expensive, but I hat the idea of tossing out a perfectly good tool just because the switch is bad. Here is the repair I did. After trying to jumper the switch internally, meaning bypassing the switch so the grinder was always turned on, I opted to slide in a piece of plastic wedge to push the switch into its ‘on’ position permanently. With the grinder always on, I wired an inline switch into the power cord.
If you switch on the angle grinder and nothing happens, the problem is likely to lie with the power supply.

How does an angle grinder motor work?
Angle grinders can be powered by an electric motor or compressed air. The motor drives a geared head at a right-angle on which is mounted an abrasive disc or a thinner cut-off disc, either of which can be replaced when worn. Angle grinders typically have an adjustable guard and a side-handle for two-handed operation.
Why does a grinder motor get hot?
Common causes of a hot running armature are due to heavy dirt build up on the inside, a broken cooling fan, cooling ports blocked – leading to poor air circulation to keep cool – or working in hot environments, overloading the motor.
How do you service a grinder?
Keep your equipment clean. After each use of the grinder, disconnect power and brush or wipe off dust and sludge (if grinding wet or using a built-in misting system). Tip back the grinder, remove tooling and wipe off the heads. Inspect plates and shroud, make sure screws and bolts are in place and tightened.
What does a capacitor do in an angle grinder?
Answer: A capacitor might be used in an angle grinder circuit to start the motor. Domestic power supply is single phase. To start a single phase induction motor we need a capacitor to initially run the motor as a split phase induction motor.
When should I replace my angle grinder disc?
Always replace a cutting disc if it shows any signs of damage. This includes, but is not limited to visible cracks and chips or any signs of bending or twists to the wheel. Cut off wheels should be replaced when they hit their expiration date. This can be found imprinted on the metal center of the disc.

What is balancing of grinding wheel?
The balancer is a system that controls the intensity of the vibrations on the grinding wheel to automatically compensate for any imbalances and improve the quality of the parts produced, specifically the surface finish (roughness) and geometry (ovality and trilobate form).
What causes a grinding wheel to become loaded?
The grinding wheel is said to be loaded when the metal particles get embedded in the wheel surface blocking the interspaces between cutting grains. Loading is generally caused during the grinding of soft and ductile materials. A loaded, grinding wheel cannot cut properly.
