When an Ikea range vent hood is overheating, start with the filters, since grease and debris can restrict airflow and force the blower motor to work harder. Remove the filters, clean them with a degreasing solution and warm, soapy water, and replace any filter that remains dirty or damaged. Next, inspect the air duct. A duct that is too small, too long, blocked, or improperly installed can reduce airflow and cause the hood to overheat. Check the outdoor vent for obstructions and make sure the vent damper opens fully. A stuck or partly closed IKEA range vent hood damper can create the same problem. If airflow is still poor, inspect the blower wheel and fan blade for grease or debris. Clean them carefully and replace either part if it is damaged or cannot be cleaned. These steps address common range hood overheating problems before you test the motor or other electrical parts.

01 - Ikea 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 - Ikea 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 - Ikea 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.
