Frigidaire FASG7021NW0 gas dryer Parts

On your Frigidaire gas dryer, the model number is printed on the appliance’s identification label (model and serial tag). For model FASG7021NW0, we use that exact number to match the correct parts, diagrams, and troubleshooting steps in the FASG7021NW0 owner's manual.

Most common places to check

Look for a sticker or metal tag in one of these spots:

• Inside the door opening on the front panel (door jamb area)
• On the back panel of the dryer cabinet
• Along the lower front frame behind the door
• Near the lint screen housing area (depending on design)

What to write down (and why)

Record the full model number and serial number exactly as shown.

• Model number: identifies the exact dryer design and compatible replacement parts
• Serial number: helps confirm production details when parts changed during a run
• Brand: Frigidaire (useful when searching manuals and error code charts)

Quick check: model number vs. serial number

Item	What it looks like	What we use it for
Model number	Letters and numbers (example: FASG7021NW0)	Picking correct parts like belts, rollers, switches
Serial number	Longer string, often numbers	Verifying production series when needed

Why it matters

Using the exact model number prevents ordering the wrong gas dryer parts (for example, a door switch, drum belt, or thermostat that looks similar but mounts differently). It also ensures any diagnostic steps you follow match your control and wiring layout.

A Frigidaire FASG7021NW0 gas dryer is built around an airflow system (blower, burner, venting), a tumbling system (drum, belt, rollers, idler), and safety and control parts (thermostats, thermistor, door switch, user interface). For diagrams and locations, use the FASG7021NW0 manual.

Main dryer parts (what they do)

• Drum: holds and tumbles clothes for even drying
• Drive system: belt, idler, and motor that rotate the drum
• Support system: rollers and bulkhead supports that keep the drum aligned
• Heating system (gas): igniter, gas valve, and coils that create heat
• Airflow system: blower wheel and ducting that move air through the drum and out the vent
• Temperature control and safety: thermistor, thermostats, and thermal safety devices
• Door and controls: door switch, catch/strike, and user interface

Common parts you may replace on FASG7021NW0

These are some frequently serviced items for this model:

• White-westinghouse dryer drum belt 134719300 (drum won’t turn, squealing, belt snapped)
• Dryer drum support roller 5304523152 (thumping, rumbling, drum not rolling smoothly)
• Dryer thermistor 134587700 (temperature issues, overheating or underheating symptoms)
• Dryer door switch 134813601 (dryer won’t start when door is closed)
• Booster coil 5303931775 (gas heat cuts in and out, weak or intermittent flame)

Quick symptom-to-part guide

Symptom	Most likely area	Example parts for this model
Drum won’t tumble	Drive system	Belt, idler, motor
Loud thump/rumble	Drum support	Rollers, bulkhead supports
No heat or heat cycles off	Gas heat + temp control	Coils, igniter, thermistor/thermostat
Won’t start	Door/control/safety	Door switch, user interface

Why it matters

Knowing the major assemblies helps you troubleshoot faster, order the right replacement part, and avoid replacing good components. It also helps you focus on airflow first, since restricted venting can mimic heating or thermostat problems.

For a Frigidaire gas dryer like model FASG7021NW0, “heating element” cost usually means the price of the failed heating-system part plus labor. Most customers spend about $200 to $400 total, depending on whether it’s an igniter, gas valve coils, thermostat, or a service call.

What you typically pay (parts vs. labor)

Gas dryers do not use the same style “heater element” as many electric dryers; heat is created by a burner assembly. Replacement cost depends on which component failed.

• DIY parts-only: commonly $20 to $150
• Professional repair (parts + labor): commonly $200 to $400
• Higher total cost happens when multiple parts are replaced in one visit (common on no-heat calls)

What failed (common no-heat causes)	What it does	Typical parts cost range
Gas valve coils	Open the gas valve when energized	$20 to $50
Burner igniter	Ignites the gas at the burner	$80 to $150
High-limit thermostat / thermistor	Prevents overheating, regulates temp	$30 to $80
Gas valve assembly	Controls gas flow to burner	$200 to $300+

Parts that commonly fix “no heat” on FASG7021NW0

If your dryer runs but won’t heat, these model-matched parts are frequent fixes:

• Booster coil 5303931775 (gas valve coil kit)
• Dryer burner igniter 5304517325
• Dryer high-limit thermostat 3204267
• Dryer thermistor 134587700

Before you buy parts: quick checks that change the cost

These checks often prevent replacing the wrong part.

• Confirm the dryer is set to a heated cycle (not Air Fluff / No Heat)
• Clean the lint screen and verify strong airflow at the exhaust
• Check that the gas shutoff valve is fully open
• If heat starts then stops, suspect coils or a temperature safety device
• Use the FASG7021NW0 manual for model-specific diagnostics and access guidance

Why it matters

A “heating element” quote can be misleading on a gas dryer; identifying the exact failed heating component (igniter, coils, thermostat, or gas valve) is what keeps the repair cost under control.

For a Frigidaire FASG7021NW0 gas dryer, “not drying” is almost always an airflow problem (lint screen, vent, or blower path) or a heat problem (igniter, gas valve coils, thermostats, or temperature sensor). We start with venting and lint buildup first because it is the most common cause.

Quick checks that fix most “not drying” complaints

• Clean the lint screen before every load; wash it with warm water if you use dryer sheets (film can block airflow).
• Confirm strong airflow at the outside vent hood while the dryer runs.
• Inspect the vent run for kinks, crushed flex duct, long runs, or heavy lint buildup.
• Try a timed dry cycle; if timed dry works better than auto dry, the moisture sensing or airflow is usually the issue.
• Do not overload; tightly packed loads dry slowly even with good heat.

If the dryer runs but there is little or no heat

On a gas dryer, the drum can tumble normally even when the burner is not firing. These are the most common heat-related suspects.

Symptom	Most likely area	What to do next
No heat at all	Ignition or gas valve	Check for burner ignition; inspect coils and igniter wiring
Heats once, then stops heating	Gas valve coils overheating	Replace the booster coil 5303931775 kit
Overheats or shuts down on high heat	High-limit safety opening	Check venting first; then test the kelvinator dryer high-limit thermostat 3204267
Poor temperature control, long dry times	Temperature sensing	Test/replace the dryer thermistor 134587700

Airflow restrictions inside the dryer (not just the vent)

If the vent is clear but drying is still slow, check for internal lint blockage.

• Lint packed in the blower housing or exhaust duct
• Crushed internal ducting
• Loose drum seal allowing air leaks
• Drum not turning at full speed (belt slipping)

A worn belt can let the drum slip and reduce tumbling action, which increases dry time. If you hear squealing or the drum movement feels weak, inspect the white-westinghouse dryer drum belt 134719300.

Why it matters

Poor airflow makes clothes take longer to dry and can cause the burner to cycle off early on safety limits. Fixing venting and lint buildup first improves drying performance and protects key parts like thermostats, coils, and the motor.
