American Water Heaters FG1F3030T3NOV water heater Parts

A typical gas water heater lasts 8 to 12 years. For your American FG1F3030T3NOV gas water heater, regular maintenance (especially draining, flushing, and anode rod inspections) helps you reach the high end of that range; water quality and usage can shorten it.

Typical lifespan ranges

Most residential tank-style water heaters fall into these ranges:

Water heater type	Typical lifespan
Gas tank water heater	8 to 12 years
Electric tank water heater	10 to 15 years

What most affects lifespan on a gas tank water heater

These factors drive tank corrosion, sediment buildup, and burner wear:

• Water quality (hard water increases sediment)
• Water softeners (softened water is more corrosive to the tank)
• Maintenance frequency (flushing and anode checks)
• Temperature setting (higher temps can increase stress and scale)
• Venting and combustion air (poor draft can affect burner operation)

Maintenance that extends service life

We recommend following the maintenance schedule in the owner's manual. Key items include:

• Drain and flush the tank periodically to reduce sediment
• Inspect the anode rod about every 3 years and replace it if it is more than 50% depleted
• Watch for odor or discoloration that can point to anode rod issues
• Check for leaks at fittings and valves and address them early
• Keep the burner area clean and make sure the unit has proper combustion air

If you are planning maintenance parts, common replacements for this model include the water heater anode rod 100109594 and the drain valve 100109106. You can order model-matched parts from the parts list for FG1F3030T3NOV, or search by model on Sears PartsDirect.

Why it matters

Once a tank begins to corrode internally, failure can happen quickly. Staying ahead of sediment and anode rod wear helps protect the tank lining, maintain heating efficiency, and reduce the chance of unexpected leaks.

For an American FG1F3030T3NOV gas water heater, the typical installed cost to replace a standard tank-style gas water heater is about $1,600 to $2,400 in many U.S. homes; higher-efficiency upgrades, venting changes, or code-required piping updates can push the total higher. Use the owner's manual to confirm venting, gas supply, and piping requirements before you price the job.

What drives the total replacement price

Replacement cost is usually a mix of the heater price, labor, and materials. The biggest cost drivers are:

• Tank size and efficiency level (basic atmospheric vent vs. higher-efficiency options)
• Venting work (draft hood, vent connector, chimney liner, power vent conversion)
• Gas line sizing or rerouting (pipe diameter and total run length)
• Water piping updates (shutoff valve, unions, expansion tank in closed systems)
• Permit and inspection fees (varies by area)
• Disposal/haul-away of the old tank

Typical cost ranges (installed)

These ranges reflect common U.S. pricing for a like-for-like tank replacement.

Scenario	Typical installed range	Notes
Like-for-like tank replacement	$1,600 to $2,400	Most common when venting and gas line stay the same
Replacement with venting changes	$2,200 to $4,000	Costs rise when venting must be modified to meet code
Tankless conversion	$2,400 to $5,400	Often needs gas, venting, and sometimes electrical upgrades

Model-specific checks that affect cost

Your FG1F3030T3NOV manual calls out installation items that can add parts and labor:

• Gas supply sizing: pipe size depends on BTU input and total pipe length
• Combustion air and ventilation: may require added openings or ducting
• Water piping: 3/4-inch NPT hot and cold connections; unions are recommended for service
• Thermal expansion protection: closed systems often need an expansion tank or relief device

Parts that may be needed during replacement

If your installer finds worn or leaking components, these are common add-ons:

• T&p valve 100108279 (temperature and pressure relief valve)
• Draft hood 100111362 (if the existing hood is damaged or missing)
• Drain valve 100109106 (if the drain is seized or leaking)

Why it matters

A gas water heater replacement is not just swapping tanks. Correct venting, gas line capacity, and safe water piping help prevent nuisance shutdowns, poor performance, and unsafe operating conditions.

For the American FG1F3030T3NOV gas water heater, the most common problem we see is ignition trouble: the pilot will not light or will not stay lit, so the burner never runs and you get little or no hot water. Sediment buildup and a leaking T&P relief valve are also frequent causes of poor performance.

Most common issues and what they look like

• Pilot will not stay lit: burner never comes on, water stays lukewarm or cold
• Dirty or restricted air intake/flame-trap: weak flame, nuisance shutdowns
• Sediment in the tank: popping or rumbling sounds, reduced hot water, slower recovery
• T&P relief valve weeping: dripping from the discharge pipe, pressure or temperature issues
• Gas control/thermostat problems: inconsistent temperature, overheating protection trips

Quick checks we recommend first (safe, no disassembly)

1. Follow the lighting steps exactly in the owner's manual.
2. Smell for gas at floor level before lighting (especially on LP models); if you smell gas, do not attempt to light.
3. Confirm the temperature setting is reasonable; 120°F is the preferred starting point in the manual.
4. Look at the pilot through the viewport while lighting; a weak or unstable pilot points to an ignition or airflow issue.

Parts that commonly solve the problem

If troubleshooting points to a failed component, these are common replacements for this model:

Symptom	Common part to check/replace	What it does
Pilot will not light or stay lit	Water heater pilot igniter 100110927	Creates/maintains ignition at the pilot so the burner can run
Pilot/ignition assembly damaged or unreliable	Water heater pilot and igniter assembly 100093808	Combines pilot and ignition components for stable lighting
Dripping from relief discharge pipe	T&p valve 100108279	Releases excess temperature/pressure to protect the tank

Why it matters

Ignition problems stop heat production entirely, while sediment and relief-valve issues reduce efficiency and can create unsafe operating conditions. The manual also notes safety shutdown behavior (for example, Flame Lock system events can permanently disable the heater), so correct diagnosis prevents repeat failures.

Some areas are moving to phase out or limit new gas water heater installations to reduce air pollution (especially nitrogen oxides) and improve indoor and outdoor air quality. Rules vary by city, county, and state; your American FG1F3030T3NOV can still be serviced safely using the instructions in the owner's manual.

What “phased out” usually means

In most places, a phaseout targets new installations or new equipment sales, not immediate removal of existing units. For a gas water heater like the American FG1F3030T3NOV, that typically breaks down like this:

• Existing heaters can usually keep operating until replacement is needed
• Repairs and maintenance are commonly still allowed
• New installs may require an electric or heat pump water heater instead of gas
• Permits and venting requirements may tighten over time
• Some programs offer incentives for switching technologies

Why it matters for your FG1F3030T3NOV

Even when local policies change, safe operation and correct installation remain the priority. Your manual highlights key safety points that directly affect real-world performance and safety, including:

• Avoiding installation near air-moving devices (exhaust fans, dryers) that can cause flue gas backdrafting
• Never storing flammable liquids or vapors near the heater
• Keeping required clearances and accessibility for service
• Following lighting instructions carefully, especially on LP (propane) models

If you are deciding between repair vs. replacement

When a gas water heater is still permitted, repairing common wear items is often practical. If you are troubleshooting ignition or pilot issues, these model-matched parts are commonly involved:

• Water heater pilot igniter 100110927
• Water heater pilot and igniter assembly 100093808
• Water heater propane gas control valve 100093749

Situation	Typical next step	Why
Pilot will not stay lit	Inspect/replace pilot and igniter components	Weak ignition or sensing causes shutdowns
Gas control problems	Check gas control valve operation	Controls gas flow and safety shutoff
You smell gas	Shut off gas, ventilate, do not ignite	Prevents fire/explosion risk

For an American FG1F3030T3NOV gas water heater, it’s cheaper to repair when the problem is limited to a serviceable part (ignition, gas control, T&P valve, drain valve). Replace the heater when the tank is leaking, badly corroded, or has been submerged in flood water (replacement is required in that case per the owner's manual).

Quick decision guide (repair vs replace)

Repair usually makes sense when

• The tank is not leaking and there’s no heavy rust at fittings or the base.
• The issue is ignition or pilot related (common on gas models).
• The T&P relief valve is weeping due to pressure/temperature events (after confirming system conditions).
• The drain valve is leaking or won’t close.
• You can restore safe operation with a straightforward part replacement.

Replace usually makes sense when

• The tank is leaking (tank leaks are not repairable).
• The heater has been under water or gas controls/burner/pilot were submerged (the manual calls for replacing the entire water heater).
• Repeated failures are stacking up (multiple parts plus labor).
• Corrosion is advanced around the combustion chamber, flue, or tank connections.

Common repairs for this model (examples)

Symptom	Likely repair path	Example part on this page
Pilot won’t light or won’t stay lit	Inspect pilot/igniter, connections, and combustion area; replace failed ignition parts	Water heater pilot igniter 100110927 or water heater pilot and igniter assembly 100093808
Water dripping from relief line	Verify temperature setting and system pressure; replace relief valve if it won’t reseat	T&p valve 100108279
Leaking at drain outlet	Replace drain valve; flush sediment after repair	Drain valve 100109106
Odor or accelerated corrosion risk	Inspect anode rod every 3 years; replace if more than 50% depleted	Water heater anode rod 100109594

Why it matters

Repairing a gas water heater is only a good value when it restores safe, reliable operation. Tank leaks and flood submersion are hard stop conditions because they create safety risks and ongoing damage. The owner's manual also highlights safety steps such as not operating the heater after submersion.
