Switch is a simple component, it is easy to let small appliances stop running. When the mixer is not working, check the switch after checking the plug and the power cord. The following describes the detection and replacement switch method:
Step 1: Gently remove the cover of the switch to expose the back of the switch.
Step 2: Check the terminals of the switch to ensure that the wires in the appliance are properly connected to the switch.
Step 3: Mark the terminal locations of the wires and disconnect them.
Step 4: Use the on-off detector or multimeter to determine if the switch is faulty. If so, replace the switch and reconnect the wire.
Maintenance speed controller:
The speed of the food mixer is controlled by changing the current transmitted to the motor. The smaller hand-held mixer uses a speed switch, which contains a lot of electrical contacts, each contact will increase the current transmitted to the motor. Larger mixers use variable resistors to control current. No matter what type of speed controller, you can use the on-off detector or multimeter to check. Sometimes, cleaning the contacts also helps improve performance. However, in many cases, the problems caused by the speed controller can only be solved by replacement.
The food mixers are easy to use because their agitators rotate in the opposite direction, so that the raw materials can be effectively mixed. This opposite rotation is caused by gears. Most of the food mixers are connected to a worm wheel on the motor shaft and two or more pinions driven by the worm gear. The pinion then drives the agitator to rotate. Since the gears are physical components rather than electrical components, the maintenance methods are different. Here's how to check and lubricate gears:
Step 1: Make sure to unplug the appliance.
Step 2: Remove the upper cover to expose the gear. In most cases, you can check whether the gears that cause the problem are damaged and then lubricated.
Step 3: Check and lubricate the worm gear and the drive gear to ensure that no excess lubricant is applied to the motor or any electronic components.
Step 4: Before reassembling, remove loose pieces or debris from the cover.
