Dynasty Range vent hood turns off by itself
When your Dynasty range vent hood turns off by itself, start with the filters, since grease and debris can restrict airflow, make the blower motor work harder, and cause it to overheat and shut off. Clean or replace the range vent hood 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 make the vent hood keep shutting off. If the filters and venting are clear, inspect the blower wheel and housing. A wheel that does not turn freely can overheat the motor. The exhaust fan motor, fan motor, or blower motor may also have worn windings or bearings, especially if the hood runs for a while before shutting off even though it still has power. Turn off power before inspecting the fan blade, and replace the faulty motor or blower assembly when necessary. These steps apply to Dynasty range vent hood troubleshooting and can help identify why the hood stops during use. Enter your model number to find the exact filter, vent cap, blower wheel and housing, or motor replacement part for your specific Dynasty range vent hood.
01 - Dynasty 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 - Dynasty 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.
