Question about Kenwood KM400 / KM410 Chef Classic Stand Mixer

1 Answer

When the power switch is touched upon start up, the fuses in the power line that is connected to my power supply (RS-35M) instantly blow. The needle in the meter on the power supply pegs instantly also, indicating a power draw in excess of the rated maximum of the power supply. I have tried this with another power supply, also a RS-35M, and the same occurs.

My Hobart H-600 commercial dough mixer shut off in the middle of grating cheese now it will not turn back on


Google perhaps a fuse is blown something was to heavy or something was under tension to the power supply that so the machine did not get the required voltage by too much taxation by other devices on the power line group

Stop using it. If the insulation on the power cord is cracked, cut, or bare, you are getting a short from a wire being exposed to the mixers body. This could cause a Fire and/or injure you directly. The source needs to found by a technician and repaired.

I have a hobart mixer D340, 40 qts. and the start botton switch is not working. Can you teach me how to change it? If you have a video that I can see to solve this problem . Thanks, I be waiting for your...


This should be a fairly simple job, the only thing that may cause some people trouble would be if the switch has solder and not push on connections. This is an NO switch (normally open) Part # 00-087711-183-4 with two wires, one each to either connection.
1.Unplugged or turn the breaker off for the mixer, pull the cap off the start button.
2. Remove one of the lower screws from the electrical control panel plate and use it to get two screws 1 inch or longer that are the same size and thread.
2. Remove the other bottom screw from the control plate and screw the 2 longer screws into the bottom holes no more than one quarter of an inch. The screws will give you room to work and support the control panel plate while you are replacing the switch. Remove the 2 top screws that hold the electrical control plate to the machine.
2.Remove the 2 screws from the front of the control plate that secure the start button in place.
3. Install the new switch, make the electrical connections, replace the 4 screws in the control plate, and push the cap back on the start button, Plug in the machine or turn the breaker back on and you're done.
PS: you should avoid touching the other components on the electrical control panel.

The switch on the inner side of the black speed control board may have become bent with your repair efforts and the contacts may no longer be touching. One part of the switch contacts is lifted and lowered by the speed link that you put back to its correct position.

Have a PVi8B mixer that has stopped working suddenly. Doesn't do anything when you flip the switch to "ON" are there fuses that could be the problem?


Does the blue power light come on when you switch it on? There is a 5amp fuse in the supply cable.Open the wall socket plug of the supply cable (unplugged of coarse) and check fuse and connections.With a multimeter check continuity of the three wires from the plug to the other end of the cable.If this is all good then you have an internal fault.There are fuses internally as well but this should be refered to a qualified technician.

Hobart k45 won't run


the K45 was introduced in 1962 and ran until 1978 when the K45SS was introduced. You have an open circuit inside, you need to open the machine from the rear and look to the power cord connections. make sure that the wires are connected and none are floating loose. the next step would be to replace the speed control switch. then check your carbon brushes if either one of the brushes are down to the nubs then it would cause a short when you turned it on, if that is the case then be glad that you have breakers and not fuses because you would have fried your motor. the speed control switch has no power attached to it. ifg the problem still exist after checking power cord, speed control plate and brushes then you have a fried armature or stator either can short the system if they have a burned wire inside especially the stator.
let us know how you fare on this after you check out the first easy steps, we can help with the harder fix also.

How do you test a 1kvolt ceramic capacitor?


Hi Mixers,
You can test a 1kvolt ceramic capacitor;
a) using a capacimetre; replacing with other one of the same type; connecting it in a 12V oscillator circuit with a LED as output wich shall blink in a frequency determined by the capacitance, says, fast with low capacitance and slow with high capacitance. Normally ceramic HV capacitors are of small capacitance for use in high switching circuits or as a protection of a power switching transistors in modern power supplies

GE Profile agitates w/o filling w water at start of cycles. Unplugging to reset worked in past but not today! Acts like it's stuck in a cycle program. Was washing earlier so water line is available and not...

It's a switch either in the control panel or at the top of the tub with a small tube connected to it which goes down between the inner and outer tube. As the water level increases the air in the tube is compressed until there is enough pressure to make the switch stopping the water from filling. This tube can get clogged and the switch won't work. Remove the tube and clean it out. Blowing on the tube when it's still connected to the switch will make the switch if it's working and clear.

Doesn't work


I just fixed mine and it sounds like some of you may have the same problem. Problem was...Lights on top come on but when you push the start button, nothing happens. The problem was the upright position kill switch. First, to get the cover off... unplug the unit. Then, right next to where you attach your beater in the center of the round plate is an octagonal piece with a pin pushed through to hold the round steel plate with the beater holder. Punch the pin out and the beater holder will come off. Now you have access to two more hex (or star) screws like the two you can see under the arm of the unit. Remove these 4 screws (the two that are under the plate and the two you could already see) and the top cover will come off. Be sure not to yank any wires too hard as it is all electronic in there. Once the cover is off, have the mixer facing with the plug end to the right and the beater end to the left. Now, looking at the insides, on the far right and closest to you, you will see a small switch which should get pressed when the unit is in the down position. It should catch on a small piece of metal that is held in place by a small philips screw. On my unit, this metal piece which should have been in place to trip the switch when the unit was down had broken off. I took a very small piece of metal about 1cm long, drilled a hole in one end so the screw would hold it in place and then bent it 90 degrees, so when the unit was in the down position, this metal piece would trip the kill switch for the motor. Anything to trip the kill switch would work. If you can't figure out what to use to trip the kill switch, you could just wrap a piece of tape or something around the switch so it is always activated, but this would potentially be unsafe as the beaters would then run in the upright position. Fixed mine in about 15 minutes...cost...free. Hope some of you can do the same.
