Jenn Air Range vent hood turns off by itself
If your Jenn Air range vent hood turns off by itself, the most likely cause is restricted airflow. Start by inspecting the vent hood filters. Grease and debris can clog the filters, forcing the blower motor to work harder, overheat, and shut off. Next, check the wall vent cap and duct for an obstruction, such as a bird's nest or other debris. Poor airflow at the inlet or outlet can make the vent hood keep shutting off. If the filters and venting are clear, inspect the blower wheel and housing. A blower wheel that does not spin freely can overload the motor. When the hood motor has power but shuts off after running for a while, worn windings or bearings in the exhaust fan motor, fan motor, or blower motor are likely. Turn off power before checking the fan blade and avoid operating the hood if wiring or a motor is overheating. Enter your Jenn Air range vent hood model number to find the exact replacement filter, blower wheel, exhaust fan motor, fan motor, or blower motor for your appliance.
01 - Jenn Air 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 - Jenn Air 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 - Jenn Air 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.

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
