Why does the cooling fan run all the time on my Viking VDSC530T?

If the cooling fan runs all the time on your Viking Cookers, it could be due to an open RTD; replace the RTD. Another possible cause is a broken wire to the RTD; repair the wiring to the RTD. The control board itself may also be defective; replace the control board.
