Tip & How-To about Coffee Makers & Espresso Machines

Grinding and blending appliances

Generally, a blade or grinding or blending/mixing part that is permanently attached to a metal shaft from the appliance motor is held on that shaft by a 'shear pin'. This pin breaks when something is put in the appliance that the grinder, mixer, blender can't gring, mix, or blend. This is to protect the motor from overload. Afterwards, The motor will continue to turn, but the blade or paddle, or whatever will not turn.
The shear pin needs to be replaced.
The shear pin passes through one side of the base of the bade/grinder/paddle assembly, through the motor shaft, and out the other side of the blade/grinder/paddle.
The piece of the pin must be removed from the shaft, and from the two sides of the blending/grinding part. This is generally a press-fit, and some effort may be required to accomplish this.
When the pieces have been removed, a common 'roll pin' of the appropriate diameter should be inserted to hol the turning part on the shaft. It must fit tightly, and some effort should be required to insert the new pin. // '); }// ]]> Back to Edit // '); }// ]]> Publish

Help its hot as hell!


Hi Holly,
If you hear the motor running - and aren't feeling air blowing thru the vents, it could be a problem with the way the fan blade is attached to the motor shaft. It may have come off the motor shaft completely, or has become loose on the motor shaft (the shaft is spinning but the blade is spinning only slowly or is stationary).
It may also be a problem wit the blend doors. Blend doors are in many vehicles that mix cold and hot air to blow the desired temperature air and they're used to direct air between or mix with vents for defroster, dash vents, and foot vent areas. Sometimes, disconnecting the battery for a minute or two will cause them to recalibrate and begin working properly again when the battery is reconnected. It is important to note that this may not be the way YOUR vehicle handles this problem - and may render your factory radio inoperable if it is equipped with an internal anti-theft circuit, so look into that before you disconnect.
Good luck!

motor spins but blade doesn't


If there is a shaft sleeve available from Kitchen Aid you will need to replace that and most likely the chopping blade if there is any damage up inside it.

grinder blade stuck inside skill saw cant get it out


Put your fingers behind the blade and pop the shaft with a plastic-headed hammer. You may have grinding residue that is jamming the release of the blade. Hope that helps!
