Wolf Range vent hood turns off by itself
When a Wolf range vent hood turns off by itself, restricted airflow is the most likely cause. Start by inspecting the vent hood filters. Grease or debris can clog the filters, making the blower work harder, overheat, and shut off. Clean or replace the filters as needed. Next, check the vent path and outside wall vent cap for an obstruction, such as a bird's nest or buildup. Poor airflow can cause the motor to overheat and stop. If the Wolf range vent hood still keeps shutting off, inspect the blower wheel and housing. A wheel that does not turn freely can point to a failing blower motor. The exhaust fan motor, fan motor, or blower motor may also have worn bearings or damaged windings, especially if the fan runs for a while before stopping but still has power. Turn off power before checking whether the fan blade rotates freely, and use caution around electrical components. Enter your Wolf range vent hood model number to find the exact replacement filter, blower wheel and housing, exhaust fan motor, fan motor, or blower motor for your specific hood.
01 - Wolf Range Vent Hood Filter
The filters in the range hood need to be clean to have good air flow. If the filters are clogged the blower will have a hard time moving air, causing the motor to overheat, and shut off. Inspect the filters and clean or replace them if necessary.

02 - Wolf Range Vent Hood Wall Vent Cap for 6 Inch Duct
If the vent hood motor keeps shutting off the venting may be obstructed. If accessible, check the outside vent cap for a bird's nest, etc. Turn the vent hood on and check for good air flow at the inlet and outlet. If you suspect the vent is clogged, but you cannot access it, you should have someone check it for you.
