If your Caloric range vent hood turns off by itself, restricted airflow is the most likely cause. Start by inspecting the vent hood filters. Grease and debris can clog the filters, forcing the blower motor to work harder, overheat, and shut down. 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 accumulated grease. Poor airflow can make the vent hood motor overheat even when the controls and power supply are working. If the filters and venting are clear, inspect the blower wheel and housing. A wheel that does not turn freely can overload the motor. A failing exhaust fan motor, fan motor, or blower motor may also run for a while, then shut off because of worn bearings, damaged windings, or overheating. Turn off power before inspecting internal parts, and do not operate the hood if wiring appears damaged. Enter your Caloric range vent hood's model number to find the exact replacement filter, wall vent cap, blower wheel and housing, exhaust fan motor, fan motor, or blower motor for your appliance.
01 - Caloric 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 - Caloric 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 - Caloric 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.
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.
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.
