Amana Range vent hood is overheating

When your Amana range vent hood is overheating, restricted airflow is the most likely cause. Start by inspecting the range hood filter. A dirty or clogged filter makes the blower motor work harder and can cause it to overheat. Clean the filter with a degreasing solution and warm, soapy water, or replace it if it is damaged or will not come clean. If the problem continues, check the air duct for an undersized or excessively long section, outdoor obstructions, and a vent damper that is not opening fully. A stuck or damaged Amana range vent hood damper can limit airflow even when the filter is clean. Next, inspect the blower wheel and fan blade for grease or debris, and clean or replace either part if it is damaged. These issues can cause an Amana range vent hood to run hot, lose airflow, or make unusual noise. Disconnect power before servicing the hood, and enter your model number to find the exact replacement filter, damper, blower wheel, or fan blade for your specific Amana range vent hood.

01 - Amana 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.

02 - Restricted Air Duct

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 - Amana 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.

04 - Filter is Clogged

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 - Amana 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.
Uncommon But Possible

06 - Amana Range Vent Hood Fan Blade

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.
