How to fix a blender motor?

Blenders work with their blades linked to the motors. The link is a metal stud or coupling that attaches the blades with the motor. As long as these two are free to rotate there won’t be any problem. But over time the blender could be overloaded. Here is how you can fix your blender.

Step 1

Check your blender with a volt-ohm meter with its RXI scale. Before that unplug the blender from the socket and turn the power switch on. Now the clip the clot-ohm meter probes to the plug prongs. Now press the speed switch of the blender, chances are you will see a low reading in it. But if the meter says the reading is infinity, then the blender CONDITION is really bad.

Step 2

Carefully detach the switch housing from the base housing by lifting the corners of decal or facing the surrounding cover of the pushbuttons. Take a matching screwdriver and remove the lower screws on the unit.

Step 3

Now you need electrical contacts that happen to clean electrical devices. Spray that on the blender, opening, terminal, etc. Front and back of the switch block. Wipe all the parts with a clean, dry cloth. If wiping does not solve the issues, you need to replace the switches.

Step 4

Remove the wire connector joining power and the lead-containing fuse. Now check the fuse well either it is blown out or not. Set the volt-ohm meter to RXI and clips the probes to both ends of the lead. You need to replace the fuse if the reading is high.

Step 5

Disable the blade coupling as far as you can to unjam the blade shaft. Take a few drops of white grease and lubricate the blade using a sponge or cotton. Don’t use a bare finger on the blade; you might end up cutting or get scratches.

Step 6

Hold the cap nut with taped pliers and start to replace the jar coupling. Now turn the coupling clockwise to and slowly remove it. If the condition indicated to replace the motor coupling, hold the motor shaft with pliers and unscrew it. After fining all the replacement or coupling units flow all these steps backward to assemble the blender.
