Buying Guide
FAQs
What should I prioritize when selecting a built‑in microwave with a trim kit?
Focus on dimensions that match your cabinet opening, the power wattage for cooking speed, and the availability of a trim kit that fits your wall thickness. Sensor cooking and preset programs add convenience, while stainless‑steel finishes blend with most kitchen designs. Also compare warranty length and customer service reputation for long‑term value.
How do the Frigidaire Gallery Series GMBS3068BF and PMBS3080BF differ in trim‑kit options?
Both models offer a 2.2 cu ft capacity, but the Gallery Series provides separate trim kits for 27‑inch (GMTK2768AF) and 30‑inch (GMTK3068AF) installations, while the PMBS3080BF only lists a 30‑inch trim kit (PMTK3080AF). The Gallery’s trim kits are sold separately, giving you flexibility to match exact cabinet widths, whereas the PMBS3080BF may require a custom solution for narrower openings.
Is the Summit microwave a better value than the Frigidaire options?
The Summit models include a full trim‑kit package at no extra cost, which can save installation time and money compared to Frigidaire units where the kit is sold separately. Both offer 1200 W power and 2.2 cu ft capacity, but Summit’s stainless‑steel front and jet‑black exterior add a premium look. If you need a ready‑to‑install solution, Summit often provides better overall value.
Can I install a 27‑inch trim kit on a 30‑inch microwave model?
Generally, trim kits are designed to match the width of the microwave and the surrounding cabinet opening. Using a 27‑inch kit on a 30‑inch unit may leave gaps and affect the finished appearance. It’s safest to select the trim kit that corresponds exactly to the microwave’s width and the cutout dimensions.
What are the benefits of sensor cooking versus manual power settings?
Sensor cooking automatically adjusts time and power based on the food’s moisture level, reducing the risk of overcooking or underheating. This feature is especially useful for reheating leftovers or cooking frozen meals. Manual settings give you full control for specialized recipes, but require more guesswork.
How important is the interior turntable size for a 2.2 cu ft microwave?
A larger glass turntable, like the 16‑inch option on many 2.2 cu ft models, ensures even heating of bigger dishes and multiple plates at once. Smaller turntables may limit the size of containers you can use, leading to uneven cooking. Choose a microwave with a turntable that comfortably fits the cookware you use most.
Are there any hidden costs I should watch for when buying a built‑in microwave?
Beyond the microwave’s price, consider the cost of the trim kit, any required mounting hardware, and possible professional installation fees. Some brands sell the trim kit separately, which can add $50‑$100 to the total. Checking for included accessories and warranty coverage helps avoid unexpected expenses.
