Wolf Range vent hood turning on by itself

When your Wolf range vent hood turns on by itself, the thermostat is the most likely cause. Many vent hoods have a thermostat that automatically starts the blower when heat inside the hood reaches a set temperature, then shuts it off after the hood cools. Check your owner's manual and wiring diagram to confirm whether this feature applies to your Wolf range vent hood. If the fan or lights turn on and off randomly, the control board may have burnt relay contacts or an internal short. A worn touchpad can also close its circuit intermittently and send an unwanted signal to the control board. Next, inspect the user control and display board, especially if some control panel buttons respond incorrectly. The main control board can cause the same intermittent operation, while a shorted control module is less common and should be considered only after testing the controls and switches. Enter your Wolf range vent hood model number to find the exact replacement thermostat, control board, touchpad, user control and display board, or control module for your appliance.

06 - Wolf Range Vent Hood Control Module

The control module receives inputs from the control panel switches to turn the lights and blower on and off. If the control module shorts out, the blower or lights may go on and off randomly. Because this is not a common problem make sure the control panel and switches are tested before replacing the control module.
