Caloric Range vent hood is overheating
If your Caloric range vent hood is overheating or feels too hot during use, restricted airflow is usually the 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. If the filter will not clean up or is damaged, replace it. Next, check the air duct for an undersized or overly long run, outdoor obstructions such as a bird's nest, and a vent damper that does not open fully. A stuck Caloric range vent hood damper can limit airflow and raise motor temperature. Grease buildup may also clog the filter, blower wheel, or fan blade. Clean these parts with dish soap and warm water, and replace any damaged blower wheel or fan blade. If the vent hood has always overheated, compare the duct installation with the manufacturer's requirements for diameter and maximum length. Enter your model number to find the exact replacement filter, damper, blower wheel, or fan blade for your Caloric range vent hood. Disconnect power before servicing the hood, and do not operate it if the motor or wiring shows signs of overheating.
01 - Caloric 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 - Caloric 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.
Common
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 - Caloric 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 - Caloric 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.
Uncommon But Possible
