Oven Thermostat / Calibration - Viking VGR30 Service Manual

The oven thermostat maintains the correct oven
temperatures in the bake and broil operations.
In bake operation, thermostat contacts close completing
the bake circuit through the bake ignitor, and bake gas
valve to neutral.
In broil operation, thermostat contacts close completing
the broil circuit through the broil ignitor and broil gas
valve to neutral.
The thermostat contacts can be checked for continuity
by using a continuity tester or an ohmmeter set to the
low ohms range. Power to the oven must be turned off
and the thermostat wiring removed when checking the
contacts for continuity.
contacts can be made by removing the control panel.
Replace the thermostat if the switch contacts are
defective.
