Viking oven temperature is consistently too high or too low compared to the set point.

Safety: Use oven-safe thermometers rated for high temperatures.

Steps:

• Place an accurate oven thermometer in the center of the oven and preheat to a common temperature (e.g., 350°F). Record the actual temperature after stabilization.
• Repeat the test at a second temperature (e.g., 450°F) to confirm consistent offset.
• Consult the Viking user manual to adjust the oven temperature calibration (offset) through the control panel, typically in ±35°F range.
• If calibration cannot correct the error or readings are inconsistent, test and replace the oven temperature sensor.
• Inspect the door gasket for leaks that may affect temperature stability.
