Most people use food mixers, but few understand how they work and how they fail. If you can gain access to these elite few and become one of them, you secure for yourself a destiny in which food mixers are purchased once and continuously repaired when they break down. You can spend the money and time necessary to purchase another appliance on train tickets or a fun cover for your mobile phone.
Here’s how food mixer’s work: they are just small appliances that contain motors and gears in them that allow them to mix your food. The gears help to translate the motor’s rotation into the opposite rotation of the beaters. Speed controllers allow you to push varied strengths of electrical current through the system, causing the motor to work as fast or slow as you desire.
There are two types of people in this world and they each have their own kind of mixer: either a portable hand mixer, or a stationary standing mixer. Standing mixers are larger and manage bigger jobs like kneading dough or mixing large batches of ingredients.
A lot of issues with your mixer necessitate very easy repairs; you can handle servicing switches, repairing speed controls, and servicing gears. Here’s how.
To check for an issue with the switch, unplug the device, remove the housing around the switch and expose the back side of the switch. Make sure the wires from the appliance are fully attached to the switch, mark the terminal wires for position, disconnect them and hook up a continuity tester to it. If the continuity tester says the circuit is healthy, move on to the next potential problem.
It could be the speed controls. The speed of your food mixer’s beaters varies as a function of the current sent to the motor. If you have a hand mixer, it uses a speed switch that utilizes several electrical contacts, each increasing the current to the motor. Larger units tend to use a variable resistor to control the electrical current. You can use a continuity tester to check for the operation of either.
If all that checks out, it’s time to move on to the gears. The beaters of your food mixer rotate in opposite directions when you set them on your pre-blended food. Gears are responsible for this opposing rotation. A worm gear is likely attached to the motor shaft, turning two or more pinion gears. These pinion gears then rotate the beaters. Unplug the machine, remove the upper housing of the beaters, then inspect and carefully lubricate the worm gear and pinion gears. You don’t want any of the lubricant to get on the electrical components that surround the gears.
Finally, your issue may lie with the fuse. If the mixer’s motor won’t start, the fuse if probably blown. Check it out by removing your food mixer’s upper housing, finding the fuse and disconnecting it from the motor. Place a continuity tester on each end to check if the fuse is working. If not, you’ll have to replace it with one of the same amperage rating.
If the fuse works, that leaves the motor. This is supposed to be one of the least likely components to fail. Check it for continuity; if it fails, mark and remove wires attached to it, disconnect the motor from the housing and make sure to find the exact same part with which to replace it.
