If your Hotpoint range vent hood turns off by itself, start with the filter. A clogged range hood filter restricts airflow, makes the blower motor work harder, and can cause it to overheat and shut off. Clean or replace the filter before testing the hood again. If the problem continues, check for a blocked vent, including a clogged duct or an outside wall vent cap obstructed by debris or a bird's nest. Poor airflow can also overheat the blower wheel and housing. When the hood has power but the fan stops after running for a while, inspect the blower wheel to make sure it turns freely. A worn blower wheel and housing, exhaust fan motor, fan motor, or blower motor may have damaged bearings or windings and may need replacement. Turn off power before inspecting or handling internal parts, and do not operate the hood if the motor is overheating. Enter your Hotpoint range vent hood's model number to find the exact replacement filter, vent cap, blower assembly, or motor for your specific appliance.
01 - Hotpoint 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 - Hotpoint 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 - Hotpoint 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.
