Kenmore Range vent hood turns off by itself
If your Kenmore range vent hood turns off by itself, restricted airflow is the most likely cause. Start by checking the vent hood filters. Grease and debris can clog the filters, making the blower motor work harder, overheat, and shut off. Clean or replace the filters as needed. If the filters are clear, inspect the duct and outside wall vent cap for an obstruction such as a bird's nest or accumulated debris. Poor airflow can also cause the motor to overheat. If the Kenmore range vent hood still keeps shutting off, check whether the blower wheel turns freely. A damaged or binding blower wheel and housing can strain the motor. A worn exhaust fan motor, fan motor, or blower motor may also shut down after running for a while, especially if the motor has power but the blade does not spin freely. Allow the hood to cool, then test the fan and listen for unusual noise or grinding. Replace the failed part rather than the entire vent hood. Enter your Kenmore range vent hood model number to find the exact replacement filter, wall vent cap, blower wheel and housing, or motor for your specific appliance.
01 - Kenmore 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 - Kenmore 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 - Kenmore 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
04 - Kenmore Range Vent Hood Exhaust Fan Motor
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 - Kenmore 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 - Kenmore Range Vent Hood Blower Motor
