Hobart L800 mixer
Not sure this will help, but here are some things you might want to consider- 1st, get a new appliance technician.
2nd, if the gearbox is not making noise, then you may want to ask a COMPETENT technician to look at your mixer and check that the mixer is wired correctly for the power that you have coming into it. i.e., if you bought the mixer from a kitchen that was using high voltage (say 240v) and you have it wired into a lower voltage, then the shaft will turn, but it will seem very underpowered.
These units have the ability to run off of more than one voltage (120V, 208, 240) and multiple phases. The internal wiring needs to be wired in accordance w/ your supply voltage and phase (there is a schematic on the trans case that you will see when you remove the mixer hood that will show you the correct configuration for your application).
You should find the full wiring schematic on the underneath of the hood when you remove it.
I would also have said competent tech check the input voltage (this can be done at the main input relay) and while he's there, check the output voltage of the same relay to insure that you don't have a partial short. On the side of the relay is a 110v thermal fuse that should be tested too.
If the contactor was shorted, your shaft wouldn't turn and you would see a small green reset on the face of the contactor that would be protruding farther than normal.
Also, on the schematic, you can find the location of the fuses and it would be in your best interest to check those as well.
Hope that helps!
