Hobart HL 662 dough mixer wont start
Posted by fixitnow on March 28, 2020 at 9:16 amHello. The mix motor doesnt start when start button is pressed and the timer doesnt start counting down. The motor contactor pulls in, but there is no output from the VFD . This is a new VFD. looking for any suggestions or service documentation . thanks

What’s the part number of the new VFD? Is it OEM?
-
yes it is a hobart part #00-937463 its a little different than the old one but they supplied a wiring harness adaptor. it has a digital display, the old one didnt . the display matches whatever is on the timer display.

Ensure the wire safety cage and the mixing bowl are installed and locked in the closed position. If they are off even a bit it won’t make contact with the safety shut off and the mixer will not start.

thanks yeh im sure we are ok there becasue the contactor pulls in and if the cage isnt closed it doesnt ?

Here is a copy of the service manual for you unit. Maybe this will help you narrow down the problem.

Your and download a copy here if the attachment doesn’t work.

Thank you so much! I dont think that manual covers this machine . the one im working on is an HL662 Legacy . would it be too much to ask for service manual for that? thanks again

AW…Shawn. I thought you were on to something.
Unfortunately that manual is for the classic H600 series mixers. Fixitnow’s mixer is a newer Legacy series mixer (represented in the model number by the L in HL).
That manual has nothing to do with his HL662 mixer. Good on you for trying, though.

You indicated in another forum that a Hobart tech replaced the VFD. Why aren’t THEY addressing this issue? After all, (per you statement there) if they replaced a $2000 VFD and it still doesn’t work, then they should see this through for you.
BTW: The part number you gave me earlier (00-937463) is NOT the part number for the VFD.
I’m confused…
EDIT: NEVERMIND. Apparently Google is NOT my friend today.
