Universal Range vent hood doesn't vent to the outside
If your Universal range vent hood doesn't vent to the outside, start with the blower motor, the most likely cause when the fan blade is not spinning. Check whether the motor is receiving power, then test the vent switch for continuity if power is missing. If the motor has power but will not turn, replace the blower motor. Next, inspect the blower wheel and housing for grease, debris, or rubbing that prevents the wheel from spinning freely. A damaged blower wheel may also need replacement. Check that the fan blade is tight on the motor shaft, and replace it if it is loose or cannot be secured. A clogged grease filter is another common reason a range hood is not venting correctly. Remove the filter, soak it in degreaser, and wash it with warm, soapy water. Replace the filter if it stays dirty or is damaged. Before ordering a blower motor, blower wheel, fan blade, or grease filter, enter your model number to find the exact replacement part for your Universal range vent hood.
01 - Universal Range Vent Hood Blower Motor
To determine if the blower motor is defective, turn on the vent hood and check to see if the fan blade is spinning. If the fan blade does not spin, ensure that power is getting to the motor. If power is not getting to the motor, test the switch for continuity. If the motor is receiving power, but the motor won’t turn, replace the blower motor.

02 - Universal Range Vent Hood Blower Wheel and Housing
One possibility is that something is caught in the blower wheel. It is also possible that the blower wheel is rubbing against the blower housing. To determine if the blower wheel is at fault, try spinning the blower fan by hand. If the blower wheel does not spin freely, check for the blower wheel for obstructions. In addition, ensure that the blower wheel is not rubbing against the blower housing. If the blower wheel is clear of obstructions, but it still doesn’t spin freely, replace the blower wheel and housing.

Check to see if the fan blade is still tightly fastened to the motor shaft. If the blade is loose, try to tighten it. If the blade cannot be properly tightened, replace it.
If the range hood is not venting correctly, the grease filter(s) may be clogged. If a filter is very dirty it can be cleaned. Remove it and soak it in a degreasing solution until the grease is dissolved. Next, wash it with warm, soapy water to remove any traces of the degreaser. If the filter does not come clean or is damaged, replace it.
