Dewalt dw474 grinder quit

The grinder stopped working abruptly, I checked voltage coming in to switch..120V checked continuity across switch, opens and closes. looked at brushes, is one brush supposed to have a spring loaded contact coming out the bottom where it contacts the armature? the other brush is slightly rounded from contact with armature and appears that the entire brush makes contact. never looked at these when they were not any problems!!!! any ideas? thanks

You need new brushes. carbon is meant to be touching the armature not the contact from the spring. Its worn down

I have a dewalt dw818 angle grinder when i press the trigger it starts spinning but if i tilt the grinder a little it stops spinning done the brushes already help please

Check your power cord. Turn the grinder on, then pull and twist the power cord, especially by the boot coming out of the grinder. If there's a break in the line, it's possible for it to work in some positions but it will die if you change the orientation of the cord to the tool.

110v grinder just stopped what is wrong

could be quite a few tings. Is the power cord cut? If you have a volt/ohms meter I would recommend trouble shooting the tool. First unplug the cord and remove the cover to expose the switch area. Checking the blades on the cord first to their switch connections and then turn the switch on and go across the terminals to the brush leads. Check the condition of the brushes for wear and so forth. It is a process of elimination.

I have a 800 hdx grinder and it just stop running no power to the switch

The most likely cause is the plug fuse. Open the plug and check the fuse for continuity. If there's no continuity replace the fuse. If the fuse is ok check that the wiring hasn't come loose. I hope that solves your problem.

Miele vacuum powerhead

My power head failed due to the handle switch. It comes apart with the Phillips screw under the vacuum kill slider. Check for continuity across the switch contact solder points.

Dewalt 4 1/2 angle grinder

A Dewalt 4-1/2 inch hand grinder that normally uses 110-120 volts? Probably fried the armature windings.

Check the switch (Out of grinder), and see if it has continuity. (OHMS test with multimeter) Pretty rare thing, but perhaps the switch took the brunt of the overload. If this is the case replace the switch.

(After checking continuity on armature, and field windings, of course. If either one is bad, a new switch won't help)

Which Model Number is it, and perhaps I can find an exploded drawing for you.

Bosch angle grinder stopped cold when tapped lightly

Yes, if you have taken the handle halves apart (unplug tool first) check with your meter thru the blades on the cord to the switch contacts and then lock the switch in the on position and check across the switch and then remove the brush caps and brushes and check thru to the brush holders, if at any time you lose continuity then that would be your problem. Let me know if I can help further.

Your dryer is equipped with a thermal fuse located behind the drum seat on the heating coil.

There are two white wires connected to the fuse. Pull those off and connect together. Your door light will come on if that is your problem. There might have been a problem that caused the fuse to blow. Check for kinked dryer hoses, dirty lint traps or anything that might have caused it to overheat. You must replace the fuse or you risk catching the dryer on fire.
