Frigidaire FRT21S6AWH refrigerator Parts

On the Frigidaire FRT21S6AWH top-mount refrigerator, the upper compartment is the freezer. It is the section designed to keep foods frozen and, on models equipped for it, supports ice maker operation and freezer temperature control (see the installation guide).

• Keeps food at freezing temperatures for long-term storage
• Circulates cold air that also helps cool the fresh food section below
• Houses freezer shelving/bins and the freezer door gasket
• Is not the “fresh food” compartment (that is the lower refrigerator section)

The installation instructions for this model emphasize a few basics that directly impact how well the freezer works:

• Level the cabinet so it sits solidly on all corners
• Confirm the door seals completely to the cabinet on all sides
• Allow proper clearances for airflow (sides/top and back)
• After changing temperature controls, wait about 24 hours before making additional adjustments

Knowing the correct name helps when you are ordering parts (like a freezer door gasket), following temperature-control instructions, or troubleshooting cooling issues that start in the freezer and affect the refrigerator section.

The most common Frigidaire refrigerator problem is not cooling properly (fresh food section warm, freezer warming, or temperatures swinging). On the Frigidaire FRT21S6AWH top-mount, the fastest wins are confirming the controls are set correctly and the doors seal tightly, then checking airflow and frost buildup. See the installation guide for the basic setup checks.

• Refrigerator warm, freezer OK: restricted airflow from the freezer, frost buildup, or an evaporator fan issue
• Freezer frosts up, then warms: defrost system problem (timer, defrost thermostat, heater circuit)
• Runs constantly: dirty condenser area, door not sealing, warm room, or temperature control set too cold
• Water leaks or puddles: clogged/iced defrost drain or water line connection issue
• Lights out but cooling OK: failed bulb or door switch issue

• Make sure fresh food and freezer controls are set; after changes, give it 24 hours to stabilize
• Confirm the door seals completely on all sides (paper-strip test around the gasket)
• Verify the cabinet is level and tilted about 1/4 inch front-to-back so doors self-close
• Check for blocked vents (don’t pack food tight against air returns)
• Listen for the evaporator fan running when the compressor runs (freezer section)

Not-cooling and frost issues usually get worse over time; the refrigerator can run longer, waste energy, and struggle to hold safe food temperatures. Door sealing and leveling are especially important on top-mount designs because small gaps quickly create frost and airflow problems.

A top-mount refrigerator like the Frigidaire FRT21S6AWH typically makes fresh-food access less convenient because the refrigerator section sits lower, and it usually offers fewer premium organization and dispenser features than many bottom-freezer designs.

• More bending for daily use: fresh food is below the freezer, so you reach down more often.
• Less “eye-level” organization: shelves and crispers can feel harder to see and sort quickly.
• Fewer built-in features on many models: water and ice dispensers are less common on top-mount units.
• Freezer convenience tradeoff: the freezer is easy to access, but the items you use most (fresh food) are lower.
• Door-swing and clearance needs: you still need space for doors to open fully and seal correctly.

Good setup helps a top-mount feel more convenient day to day. We recommend using the clearances and leveling steps in the installation guide.

• Level the cabinet so doors close easily and consistently.
• Confirm the door seals contact the cabinet on all sides.
• Set fresh food and freezer controls, then wait 24 hours before making more adjustments.
• Keep heavier, frequently used items on mid-level shelves to reduce bending.
• Recheck for water leaks after 24 hours if your unit is connected to a water supply.

If you are deciding whether to keep or replace a top-mount refrigerator, the biggest real-world factor is ergonomics: how often you bend for fresh food. Proper leveling and door sealing also matter because poor alignment can cause warm spots, frost, and higher energy use.

The Frigidaire FRT21S6AWH is not considered a high-end refrigerator; it is a practical, value-focused top-mount model built around reliable everyday cooling rather than premium finishes or advanced features. For setup and performance basics, use the installation guide.

High-end refrigerators typically include more premium materials and convenience features than most top-mount designs.

Common high-end traits include:

• Counter-depth or built-in styling
• Dual evaporators or advanced humidity management
• Quieter, variable-speed compressors and fans
• Interior water dispenser, advanced filtration, or smart features
• Premium shelving, lighting, and exterior finishes

This model is best described as a standard, budget-to-midrange top-mount refrigerator.

What you can expect it to do well:

• Dependable fresh food and freezer cooling
• Straightforward controls and serviceable design
• Common, widely available replacement parts (bins, gaskets, bulbs)

Knowing the category helps set expectations for noise, temperature recovery, and features. It also helps you decide whether a repair (like replacing a worn door seal) makes sense versus upgrading.

If you are troubleshooting cooling or frost issues, common service parts on this model include the refrigerator timer 215846602 and the refrigerator defrost bi-metal thermostat 5303918202.
