What to do if my Viking VGRC485 door locks, fan runs, but no heat?

If the door lock motor is engaged on your Viking Ranges, the cooling fan motor runs, but there is no heat, it could be due to: * The door lock module/timer relay not closing. * A problem with SW3 on the door lock assembly. To fix this, you may need to replace the PC board or SW3.
