Customer Reviews
The filler panels were designed to fit the microwave for which they were purchased and they fit as expected. The panels were sturdy and well made. They fill the gaps and have a nice appearance. Installation was not difficult. The manufacturer designed the panels with screwdriver access holes. The holes allowed a screwdriver to extend through the side of the panels for attaching the mounting screws.
So unfortunately I had to replace my 17 year old 36 inch microwave, it was over $2000 if I wanted to replace it with the same size. Instead I went with the standard 30 inch that’s readily available in big box stores. I ordered this “filler” off of Amazon because the name brand filler was just as much (if not more expensive) than the microwave itself from the big box store. Product shipped fast, looks great and serves its purpose without breaking the bank. 10 out of 10 would recommend.

Frequently Asked Questions
Q: What size trim kit do I need for my over-the-range microwave?
A: Most standard over-the-range microwaves require a trim kit that’s either 2.95″ or 3″ wide. Measure the gap between your microwave and cabinet sides to ensure proper fit. If unsure, check your microwave’s manual or search by model number online.
Q: Can I install a trim kit myself?
A: Yes! Most trim kits are designed for DIY installation and include step-by-step instructions. You’ll typically need only a screwdriver. However, if your cabinets are custom-built or heavily modified, consulting a handyman might save time and prevent damage.
Q: Do trim kits work with all microwave brands?
A: While some kits are universal and fit multiple brands (like Whirlpool or GE), others are model-specific (such as Samsung or Panasonic). Always verify compatibility before purchasing. Universal kits usually list compatible brands clearly in the description.
Q: Will a trim kit affect microwave ventilation?
A: No—properly installed trim kits are engineered to preserve airflow. Just avoid blocking vents or using adhesive-only methods that could trap heat. Follow manufacturer guidelines closely during installation.
Q: How do I clean my microwave trim kit?
A: Wipe stainless steel kits with a damp cloth and mild detergent. For black finishes, use a dry microfiber cloth to prevent streaking. Avoid abrasive cleaners that could scratch the surface over time.
In conclusion, choosing the right trim kit for over the range microwave is a smart investment that enhances both form and function in your kitchen.
