Step 4: Setting Up for Recirculation (If Applicable)
If external venting isn’t an option, here’s how to prepare your microwave for recirculating venting:
1. Install Filters
Most over-range microwaves come with or require charcoal or grease filters for recirculation. These can often be installed by simply sliding them into designated slots in the microwave.
2. Adjust Ducting Direction
Make sure the inner ducting vents directly back into the kitchen instead of out through the ductwork.
Step 5: Finalizing the Installation
After the microwave is securely in place and connected:
1. Turn On the Power: Reconnect the power to the microwave and test its functions. Check the light, fan, and display.
2. Conduct a Smoke Test: To ensure proper airflow, turn on the microwave and test it by heating water or something safe that produces steam, making sure the steam is vented outside.
Maintaining Your Venting System
Regular maintenance is key to prolonging the life of your over-range microwave and ensuring effective venting. Here are some tips to keep in mind:
1. Clean or Replace Filters
For recirculating models, ensure you clean or replace the air filter regularly, as a clogged filter can inhibit airflow. Depending on usage, this might be needed every few months.
2. Inspect Ducts
For externally vented microwaves, periodically inspect the ductwork for any obstructions or buildup that may affect airflow. Certain materials, especially grease, can build up over time, so ensure your ducting is clear.
3. Service Regularly
If you notice any decreased performance or unusual noises, consider having a professional inspect your microwave. Regular servicing can help catch small issues before they turn into costly repairs.

What is the difference between venting and recirculating for over-range microwaves?
The primary difference lies in the method used to eliminate smoke, odors, and heat. Venting microwaves utilize an external duct to expel air outside of your home. This method is often preferred as it provides more effective removal of cooking smells and heat, leaving your kitchen fresher and cooler.
On the other hand, recirculating microwaves filter the air through charcoal or grease filters and then return it back into your kitchen. While this option can be more convenient for installations that don’t allow for external ducting, it may not be as efficient at removing all odors and heat, requiring more frequent filter replacements.
Can I convert my recirculating microwave to a venting model?
Many models of over-range microwaves are designed to allow conversion from recirculating to venting, but it depends on the specific model. Check your microwave’s manual to see if it offers this flexibility. Manufacturers often provide the necessary parts or kits to complete the conversion.
If your microwave does not support conversion, you might consider replacing it with one that allows for ducted venting. Be sure to consult with a professional if you’re unsure about the installation process or whether your kitchen can accommodate ductwork.
