On the Kenmore 153336466 gas water heater, the main serviceable parts include the burner and pilot system, gas control valve and temperature adjustment, venting components, and safety devices like the T&P relief valve. For the complete illustrated parts list, use the owner's manual.

Common parts you will see on this model

These are the most common components customers identify when troubleshooting, maintaining, or ordering replacement parts:

• Burner system: burner, burner tube, burner orifice, and burner assembly
• Ignition and pilot: pilot assembly and piezo igniter
• Safety and pressure protection: temperature and pressure (T&P) relief valve
• Corrosion protection: anode rod
• Water flow components: inlet tube (dip tube) and water line connector
• Venting: draft hood and flue-related parts (baffle, restrictor)
• Access and sealing: outer door, inner door, gaskets, viewport assembly

Quick “what it does” guide

Part or system	What it does	Common symptom when it fails
Anode rod	Protects the tank from corrosion	Rusty odor, faster tank corrosion
Pilot assembly	Keeps a stable pilot flame for ignition	Pilot will not stay lit
Burner and burner tube	Heats the tank water	No hot water, weak heating
Gas control valve/thermostat knob	Regulates gas flow and temperature	Water too hot, too cool, or fluctuating
T&P relief valve	Releases excess pressure/temperature	Dripping or discharge from relief line

Parts customers replace most often

If you are ordering parts for the Kenmore 153336466, these are common replacements that match this model’s parts list:

• Anode rod 100109624
• Water heater pilot assembly 100109290
• Water heater temperature and pressure relief valve 100108279

Why it matters

Knowing the major parts helps you troubleshoot faster and order the correct replacement. For example, a “no hot water” complaint often points to the pilot or burner system, while a discharge tube leak often points to the T&P relief valve.

Ordering tip (to avoid wrong parts)

When ordering, match model number, serial number, gas type (natural or propane), and the part description listed for the Kenmore 153336466. You can order parts from the parts list for this model, or search by model number on Sears PartsDirect.

The most common gas water heater problem is the pilot light going out or not staying lit, which stops the burner from heating water. On Kenmore model 153336466, pilot outages can also be triggered by excessive condensation dripping onto the burner area, especially during heavy hot-water use with very cold refill water (see the owner's manual).

Quick checks we recommend first

• Confirm the gas control is set correctly (OFF, PILOT, then ON) and follow the lighting steps exactly.
• Look for signs of condensation: sizzling or frying sounds, water droplets, or moisture near the burner door.
• Check for venting issues (sooting or deterioration in the flue or vent system).
• Verify the thermostat setting; water temperature at the tap can vary and can be dangerously hot above 125°F.
• If you notice a rotten egg smell, treat it as an anode rod related odor condition and ventilate hot water lines before using appliances.

Common causes and what they usually point to

Symptom	Most likely cause	What to do next
Pilot will not stay lit	Pilot assembly issue or condensation putting out the pilot	Inspect for moisture and consider replacing the pilot assembly
No hot water or weak heating	Burner or burner tube/orifice issue	Inspect burner area and venting; service or replace burner components
Water on the floor (not a tank leak)	Condensation or a leaking connection	Allow 1 to 2 hours for warm-up; then re-check fittings
Drips from relief valve	Thermal expansion or high water pressure	Evaluate pressure/expansion control; replace valve if it leaks at the tank fitting

Parts that commonly solve “pilot out” complaints

If troubleshooting points to ignition components, these are common replacements for this model:

• Water heater pilot assembly 100109290 (ignition and flame sensing assembly)
• Water heater pilot assembly 100109261 (alternate pilot assembly option listed for this model)
• Water heater burner assembly 100109251 (burner and related components)

For ordering, we list model-matched parts for Kenmore 153336466 on this page; you can also search by model number on Sears PartsDirect.

Why it matters

A pilot that will not stay lit is more than an inconvenience; it can indicate condensation, venting problems, or burner issues that affect safe combustion and consistent hot water delivery.

For a 50-gallon gas water heater like Kenmore model 153336466, average labor to install typically runs $400 to $1,000. Labor goes up when the installer must modify gas piping, venting, or add code-required items such as an expansion tank or a new shutoff.

What usually changes the labor price

Labor is mostly about time on site and how much has to be brought up to code.

• Venting changes (draft hood, flue sizing, chimney liner, power vent conversions)
• Gas line work (new shutoff, sediment trap, resizing pipe)
• Water piping updates (new shutoffs, dielectric unions, rerouting)
• Thermal expansion control (adding or resizing an expansion tank)
• Access and removal (tight closets, attic installs, stairs, haul-away)
• Permits and inspections (varies by city and county)

Typical labor scenarios (labor only)

Install situation	What it includes	Typical labor range
Straight swap	Disconnect old, set new, reconnect existing lines	$400 to $700
Moderate updates	Minor vent or gas piping changes, new valves	$700 to $1,200
Complex install	Significant venting or gas line rework, tight access	$1,200 to $2,000+

Model-specific notes that affect installation

Your 153336466 is a gas water heater; the manual calls out safety and code-related items that can add labor time.

• A sediment trap (drip leg) is typically installed on the gas line per code guidance in the manual.
• Installations above 7,700 feet require a high-altitude orifice change; that adds parts and labor.
• If your home has a pressure-reducing valve or backflow device, an expansion tank is often needed; sizing guidance is shown in the owner's manual.

Why it matters

Gas water heater installs are not just “hookups”; correct venting and gas piping help the burner run cleanly and reduce nuisance shutdowns. Proper pressure control also helps protect the tank and the temperature and pressure relief system.

Parts that are commonly replaced during an install

These are common “while we’re here” items that can affect labor if they are corroded or leaking:

• Water heater temperature and pressure relief valve 100108279
• Water shutoff valve and supply connectors (as needed)
• Expansion tank (when required by plumbing conditions)

You can order replacement parts for Kenmore 153336466 from the parts list for this model, or search by model number on Sears PartsDirect.

For your Kenmore 153336466 gas water heater, repairing is cheaper when the problem is limited to replaceable parts (pilot, burner components, or a leaking valve). Replacing is cheaper when the tank is leaking, the unit was flooded, or combustion and venting problems make continued operation unsafe.

Quick decision guide

• Repair for pilot ignition problems, burner not lighting, or a valve seep.
• Repair when water on the floor is condensation or a loose connection.
• Replace when water is coming from the tank body (tank leak).
• Replace if the heater has been flooded (the manual says it must be replaced).
• Stop using and correct the cause if you see sooting at the burner or pilot.

Common repairs and parts for model 153336466

These are common, targeted fixes that usually cost less than replacement:

• Pilot will not stay lit: water heater pilot assembly 100109290 or water heater pilot assembly 100109261
• Burner issues: water heater burner assembly 100109251 or water heater burner assembly 100109246
• Safety valve leaking: water heater temperature and pressure relief valve 100108279
• Corrosion prevention: anode rod 100109624 or anode rod 100108260

Repair vs. replace comparison

Situation	Usually cheaper	Notes
Pilot will not stay lit	Repair	Replace pilot assembly and verify gas supply is on
Water on floor at startup	Repair	Often condensation or a fitting leak
Relief valve seep	Repair	Replace valve or reseal fitting
Tank leak	Replace	Tank failure is not a practical repair

Why it matters

A gas water heater with sooting or venting issues can be dangerous. Use the owner's manual to follow the inspection and shutdown guidance before deciding on parts or replacement.
