Over-the-Range Microwave - Oven Vent System Draw

The Over-the-Range Microwave vent system should properly remove most heat, steam and smoke coming from the cooktop surface. If boiling or simmering for long periods of time on the front burners, the vent will not always be capable of capturing all of the excess steam. It may be necessary to use the back burners in this case.

 

The tissue test below can be used to check for proper draw of the vent:

• Turn the vent fan on HIGH and hold a tissue or paper towel under the vent area. The suction should hold the tissue or paper towel in place. The draw is equal on both sides. It is normal to have some air blowing out of the top grill.

 

If the vent does not hold the tissue or paper towel:

• Check for proper installation of the microwave vent ductwork. Refer to the Installation Instructions for the model you own for complete instructions.

• If your microwave is vented internally (recirculating), we recommend replacing the charcoal filter every 6 to 12 months, depending on usage. If a replacement charcoal filter is needed, you can order a new filter from our GE Appliances Parts & Accessories website.

If the vent is installed properly and is still not drawing air properly, service may be needed. For service, please schedule a repair appointment with GE Appliances Factory Service.
