It might need the brushing replaced, sometimes just adjusting them works, or cleaning them. You could also look at all the solder joints to insure that they are in tact. I've found that the switch is the week point in a lot power tools. You can check the switch by using a multi-meter and ohming it out. With the meter set to the Ohms setting you should read zero Ohms with the switch set to on and a really high number if not a bunch of flashing 8's depending on the meter when set to off.

try having someone turn the machine on and off while you pull the cord in and out with the cord more angled towards the on/off switch. Sometimes these models have a break in the cord rewind and will not put the power through to the motor.

Keep in mind this is repairable, and if the unit is less than 5 years old it should still be under warranty.

Good luck .

The fridge stopped working. what to do. its three years old


It could be due to following reasons 1 There is no power supply. Check the power cord and the plugs. Ensure that there is bend/breakage in the power cord. Ensure that the plugs are connected properly with the cord. If the lamp inside the fridge is lighting that means the power supply is OK. 2 The compressor has stopped functioning or burnt due to overload. 3 The gas has leaked out. You must have noticed less cooling over the months. 4 Check the thermostat switch.
For 2 & 3 you will have to call a technician. I hope you have been carrying out the servicing once a year.

Trimmer won't operate, is less than year old. Connect to cord and won't operate


Try something else (a lamp) in the extension cord. If ok, the case must be opened to expose the wiring. Check for 110-120 volts AC at the cord ends. If nothing, the plug end may have a broken wire. Cut back the end somewhat and install a new plug or just replace the power cord. If still nothing, remove the power connection and ohm-check the switch and motor. The switch should read zero ohms when on and the motor will usually read less than 20 ohms if good. If either reads infinity, replace the switch if so, and check the motor brushes for sticking or bad springs.Hope this makes sense and helps!

Motor hangs will not turnover until hand turn flywheel


Hi there,

Same symptoms occur in vehicles from time to time. It was your 'hand turn the flywheel' that made me lean toward this diagnosis.

Although You have not supplied the make/model I can make a few assumptions. The symptoms you describe sound like a worn relay/solenoid supplying power to the starter motor.

When the contact surfaces are at the end of their usable life, less and less of the 'cold cranking amps' get past them. So instead of freely flowing to the starter, the power is bottlenecked.

Check what ever mechanism your generator employs to provide starting power.

If you found this to be useful, please take a moment to rate.

Best regards
Mike

Won't start


Hello rperlin. Your AC cord most likely has a broken wire in it. Please be careful is this action I suggest and DON'T touch a bare wire. Plug unit in, turn power on, now sowly flex the AC cord close to the plug, no sparks or motor starts, flex the cord near the vacuum, ext. If you get an action you have found the location of your broken wire. Replacing it will be a chore. Make notes on wire color and witch one went where. A factory replacement may be costly, Visit your local hardware store & ask for help in electrical dept. Electrical lesson#2. Aquire a DVM or more commonly VOM(meter) & check for ohms in the AC cord. IF you elminate the cord HOUSTON WE HAVE A PROBLEM. Your switch, motor brushes, or control switches internal are the problem. Good luck.

Mine stopped working and the overheat light comes on. it will run in reverse OK, but as soon as you go to forward and put a peice of paper in it, red overheat light comes on right away. Took it apart, inside was totally jammed with shredded paper and dust. Packed tight around the motor, gears, everything. It;s a miracle it didn't catch fire! Poor design. Motor commutator was badly glazed, took apart an cleaned it. Still sparks like mad. I think it's toast! Didn't really last that long (less than 2 years) and it wasn't cheap. It going in thr trash I think!
