Working on another Hobart AM 14T The temps on the rinse get to 200, the board control the electric booster heater built into the DW. Is there any way I can calibrate the urcuit board, I replaced the booster temp probe already.

Here’s the parts manual:

Item #27 on page 6 and 7 is the temp control board for the booster for CURRENT CONSTRUCTION machines as of 2004.

 

Here’s a picture of that booster’s temp control board.  Part number 00-475458-00001:

Perhaps the potentiometer there on the board is a way to calibrate it.  I’m not a Hobart tech, but I’d explore that.

Just wondering,  Did you check the ohm values vs. temp for the probe before you condemned it as being bad?  Was the probe clean? 

 

Control systems relays sometime do stick. That’s why we have limit switches.  Sounds like your near the limit.

fixbear, aren’t Hobart temp probes 100kΩ thermistors?

 

I’ve never seen it in writing, but I came to that conclusion through my own tests.

I believe them to be type “K” terminators,  but may be wrong.

The interesting part about this board is that it is also used by Vulcan Hart and cost 200 less.
