01Exact identity
The model number defines the installation system.
Built-in microwaves that look nearly identical can use different trim kits, openings, ventilation requirements, and installation instructions.
ReplaceIQ / Built-in microwaves
Replace a built-in microwavewithout guessing at the cabinet.
Start with the exact microwave already installed. ReplaceIQ keeps model identity, cabinet opening, trim system, electrical location, airflow, clearances, and manufacturer documentation connected before a replacement conclusion is presented.
Installation analysis
Cabinet, trim, electrical, and airflow requirements stay tied to documented evidence.

Installation review
Four systems can change the answer.
A built-in microwave is not defined by the front dimensions alone. Trim, opening, electrical placement, and airflow can all change what works.
02Opening + trim
The cabinet opening and trim kit belong together.
The documented opening, trim arrangement, overall dimensions, and manufacturer-approved trim system need to be checked for the exact model.
03Electrical
Power location can decide whether the installation works.
Electrical supply, receptacle location, cord routing, and access requirements should match the manufacturer installation documentation.
04Airflow + clearance
Built-in does not mean sealed into the cabinet.
Ventilation paths, required clearances, surrounding cabinetry, and any airflow conditions remain part of the fit decision.
Before you choose
Document the built-in system.Not just the microwave.
These details help separate a real installation requirement from a visual assumption about what should fit behind the trim.
- 01
Identify the exact microwave model
Photograph the complete model number from the rating label. Do not rely on the appearance of the door, control panel, or trim.
- 02
Document the existing trim system
Record the trim kit, frame, mounting arrangement, and visible cabinet relationship. A trim kit should not be assumed to be universal.
- 03
Measure the actual cabinet opening
Record usable width, height, and depth before selecting another unit.
- 04
Verify the electrical location
Check the receptacle, supply requirements, cord path, and accessibility against the exact installation instructions.
- 05
Record airflow and clearance conditions
Note ventilation openings, nearby cabinet surfaces, gaps, and any manufacturer-required airflow path.
- 06
Keep the source document with the measurements
Measurements become more useful when they remain tied to the manufacturer installation document that explains how they apply.
Result logic
Missing evidence stays visible.
ReplaceIQ should never turn an unknown trim, clearance, receptacle, or airflow requirement into an unsupported compatibility claim.
SUPPORTED
Documented requirements line up
The available evidence supports the relevant installation conditions, while any remaining field checks stay visible.
MODIFICATION
The built-in system may need a documented change
A cabinet, trim, electrical, or installation adjustment may be possible, but it should be explicit rather than hidden inside a simple fit claim.
VERIFY
Important evidence is still missing
This does not mean the replacement fails. It means a required installation fact has not yet been established.
Evidence policy
The trim kit is not the evidence. The documentation is.
ReplaceIQ keeps manufacturer source material connected to model identity and installation requirements so an unanswered question remains an unanswered question.
