Home Warranty Microwave Coverage Built-In vs. Countertop - What's Covered (2026)

Home warranty microwave coverage almost always refers to built-in units. Countertop microwaves are excluded by every standard plan.

Updated June 2026

The key distinction: built-in microwaves (over-the-range, wall-mounted) are covered in comprehensive plans. Countertop microwaves are not - they're portable appliances that cost $50–$200 at retail, not permanent installations.

Built-In vs. Countertop - The Critical Distinction

Built-In Microwave

Over-the-range unit or wall-mounted unit - permanently installed. Typically covered in comprehensive plans.

Replacement cost: $300–$800+ installed

Countertop Microwave

Portable appliance - NOT covered by any standard home warranty plan.

Replacement cost: $50–$200 at retail

What Built-In Coverage Includes

Magnetron - the component that generates microwave energy (most common failure)
Electrical controls and keypad
Door mechanisms and switches
Turntable motor
Exhaust fan motor (for over-the-range units that include a range hood)

What's Excluded

Cosmetic damage - door cracks, scratches, discoloration
Interior liner - damaged interior walls
Light bulbs - consumables, not covered
Turntable glass plate - accessories, not covered

The Service Fee Math

Magnetron or Board Repair

$150–$400

Coverage works well here - pay service fee, warranty covers repair cost. Math favors filing.

Unit Replacement

$300–$600

Installed. Company-supplied replacement + service fee is usually a good deal vs. out-of-pocket.

Before Filing - Check These First

File only for genuine mechanical failure. Check these non-claim items first:

Sparking - usually debris inside; clean the interior first
Light is out - replace the bulb directly
Turntable wobbles - remove and reseat the glass plate
Not heating properly - test with a cup of water for 1 minute first

File when: The microwave won't start at all, displays an error code, the magnetron isn't producing heat (confirmed with water test), or the door latch has mechanically failed (the door won't stay closed). These are genuine mechanical failures - not maintenance issues.
