Krups produce a premium product and it would be surprising if they didn't also have a repair or exchange service. Sometimes such a service is a reasonable cost and it is advisable to at least make the enquiry before proceeding further with your home repair.
Early food mixers used a number of series resistors for speed control and the circuit was fairly straightforward to check with a multimeter and any capacitors found are likely to be radio interference suppressors.
Later mixers use an electronic speed control and the best mixers use feedback to maintain the speed and torque when mixing or beating viscous material that would otherwise slow the speed significantly.
Checking/troubleshooting the electronics are beyond the scope of home repair, however, the circuit can be checked to the speed control fairly simply and then from the speed control to the motor and the motor itself. If everything else checks out then it would be reasonable to assume the electronic speed control has failed.
Early electronic speed control used either a thyristor as the control device or a diac/triac pair mounted on a small circuit board. Later types probably use a speed control module similar in principle to those found in power drills...
The speed selector circuit has been compromised but either an electrical short, or disruption from particles that entered the switching mechanism and covered contacts. Needs technical attention.
need clarification. what does cut out mean? The motor stops altogether? The beaters stop spinning but you still get motor sounds? It comes on and goes completely off while in use and then comes back on. is there ever a bad smell or smoke? Are there any unusual sounds that you hear before it does a cut out or after it comes back on? Does it ever go up or down in speed on it's own. do the attachment gears on top spin while you are mixing in the bowl? we need to narrow the field of questions down to get to the right repair path. Please let us know.
I'd say you're most likely overloading the mixer. This mixer, and others similar in size, are frequently overloaded by people making pizza dough. If you are making dough, keep in mind the A-200's capacity is 9 lb. of 40% A.R. pizza dough, mixed for 5 minutes maximum. If you need to mix longer, the batch must be cut down even smaller, but I don't even know if you're mixing dough.
Try running the mixer unloaded (i.e. nothing in the bowl) for ten minutes or more and see if it gets hot. If it still gets hot, the motor's start circuit (varies depending upon age of the A-200; Hobart used numerous motors in the A-200 over the years, incorporating different starting circuits) most likely has problems. If it doesn't get hot when operating unloaded, then you're probably overheating the mixer by overloading it.
the motor protection board is doing its job.you should only use 1st speed to mix pizza dough.im a hobart technician and service these mixers all the time.let me know
