Home › Forums › The Hot Side › Vulcan oven not heating..
I'm working on Vulcan oven, model VC4ED, for the school district that I work for.
I got call saying the temperature ramped up from 350 degrees to almost 500 degrees and then came back down to about 250 degrees.
I suspected it to be the temperature probe or temperature control board, so I changed them both.
I checked the high limit switch and it's closed.
I changed the contactor for the heating elements, thinking it may have been coil, still not working.
Checked power to temperature control board, I have 208V. Checked voltage control voltage at temperature control board, have 208V. I have 208V control going to the coil, and it's pulling in and the fan is running.
But I do not have 208V of control voltage going to the coil on the contactor for the element.
Any advice is appreciated.. replied hour, 29 minutes Member · 0 Replies... 0 Replies...
