Is your Electrolux range vent hood overheating? Restricted airflow is the most likely cause. Start by inspecting the grease filter. A clogged or damaged filter makes the blower motor work harder, which can cause the range vent hood to become too hot. Clean the filter with a degreasing solution and warm, soapy water, or replace it if it will not come clean. If the filter is clear, check the air duct for an undersized duct, excessive length, or an outdoor obstruction such as a bird's nest. The vent damper may also be stuck closed or unable to open fully, restricting airflow and overheating the motor. Less commonly, debris or damage in the blower wheel or fan blade can reduce airflow and create an overheating problem. Clean these parts carefully and replace them if damaged. These steps can help whether you are troubleshooting an Electrolux range vent hood that runs hot or a hood that overheats during use. Enter your model number to find the exact replacement filter, damper, blower wheel, or fan blade for your specific Electrolux range vent hood.
01 - Electrolux 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 and the motor can overheat. Inspect the filter and clean or replace them if necessary.

If the range vent hood has always been too hot, inspect the air duct. If the air duct diameter is too small or the length of the duct is too long, the air flow will be restricted, possibly causing the vent hood to overheat. Refer to the installation instructions for proper vent size and maximum length. You can also inspect the outdoor vent hood for obstructions (a bird's nest, etc.) and confirm the vent damper is operating properly.
Highly Likely
03 - Electrolux Range Vent Hood Damper
Most vent hoods have a damper to help keep the outside air from migrating back into the house when the vent is not in use. If the damper is stuck closed, or not opening all the way, the air flow may be restricted causing the motor to overheat.
If the range hood is overheating, 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.
Common
05 - Electrolux Range Vent Hood Blower Wheel
If the blower wheel is clogged with debris the air flow will be restricted which can cause the range vent hood to overheat. You can try cleaning the blower wheel with dish soap and warm water. If the blower wheel cannot be cleaned or is damaged, it will need to be replaced.
If the fan blade is clogged with debris the air flow will be restricted which can cause the range vent hood to overheat. You can try cleaning the fan blade with dish soap and warm water. If the fan blade cannot be cleaned or is damaged, it will need to be replaced.
