KitchenAid Range vent hood turns off by itself
When your KitchenAid range vent hood turns off by itself, the most likely cause is restricted airflow. Start by inspecting the vent hood filters. Clogged filters make the blower work harder, which can overheat the motor and cause it to shut off. Clean or replace the filters as needed. Next, check the wall vent cap and duct for an obstruction, such as a bird's nest or debris. Poor airflow can also overheat the blower wheel and housing. If the KitchenAid range vent hood keeps shutting off while it still has power, check whether the blower wheel turns freely. A binding blower wheel, worn bearing, or damaged housing can overload the motor. The exhaust fan motor, fan motor, or blower motor may also have failed windings or bearings, especially if the motor runs for a while before shutting down. Disconnect power before inspecting or testing components, and replace the faulty motor or blower assembly when necessary. Enter your model number to find the exact replacement filter, wall vent cap, blower wheel and housing, or motor for your KitchenAid range vent hood.
01 - KitchenAid 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 - KitchenAid 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.

03 - KitchenAid Range Vent Hood Blower Wheel and Housing
The blower has a motor that can overheat and shut off. If the motor is not turning freely, or is running for awhile and shutting off, but still has power to it, the blower will need to be replaced.
Highly Likely

If the exhaust fan motor has power to it but keeps shutting off, the windings or bearings may be bad. Try turning the fan blade by hand. If the fan blade does not turn freely, or the motor keeps shutting off when it has power to it, the exhaust fan motor will need to be replaced.
Highly Likely
05 - KitchenAid Range Vent Hood Fan Motor
If the fan motor has power to it but keeps shutting off, the windings or bearings may be bad. Try turning the fan blade by hand. If the fan blade does not turn freely, or the motor keeps shutting off when it has power to it, the fan motor will need to be replaced.
Highly Likely
06 - KitchenAid Range Vent Hood Blower Motor
If the blower motor windings or bearings are bad the motor may overheat and shut off. Make sure the blower wheel turns freely. If the motor doesn’t turn freely, or the motor is shutting off after it runs awhile, the motor may be bad and will need to be replaced.
