Kenmore 153339561 water heater Parts

To tell the year your Kenmore gas water heater model 153339561 was made, we use the serial number on the rating plate and decode it using the manufacturer’s format (the format varies by maker). Your owner's manual shows where to find the model/serial label; once you have the serial, match its pattern to the correct brand family.

Where to find the serial number on model 153339561

Look on the model rating plate on the front of the water heater.

• Turn a flashlight on the front jacket panel
• Look for a label that lists model number and serial number
• Copy the serial exactly (include letters and dashes)
• Take a photo before cleaning the label
• If the label is dirty, wipe gently so characters stay readable

How to decode the year (common serial number patterns)

Serial formats are not universal; Kenmore-branded water heaters are often built by major tank manufacturers, so the decoding method depends on who made the tank.

• Numeric date codes: the first 2 or 4 digits often indicate year or month/year
• Week-based codes: some use YYWW (year, then week of the year)
• Letter-based codes: some use letters for month and year (the year code can repeat on a cycle)
• Mixed formats: letters plus numbers where only certain positions are the date

Quick pattern guide (use the one that matches your serial)

What the serial starts with	Typical meaning	Example of what you can read from it
4 digits like MMYY	Month and year	0821 = Aug 2021
4 digits like YYWW	Year and production week	2315 = 2023, week 15
1 to 2 letters then numbers	Letter-coded month/year	Use the maker’s letter chart

Why it matters

Knowing the manufacture year helps you plan maintenance (like flushing sediment) and decide when to replace wear items that affect performance and safety, such as the anode rod or the temperature and pressure relief valve.

If you are ordering parts, we use your model number and serial number to match the correct gas type and components. Common parts for this model include the anode rod 100108660 and relief valve 100108279.

For a typical 50-gallon gas water heater installation, labor commonly runs about $400 to $1,000. For Kenmore model 153339561, labor goes up when the job requires venting changes, gas piping updates, a sediment trap, or added safety items specified in the owner's manual.

What drives labor cost up or down

Labor pricing is mostly about how much work is required beyond swapping the tank.

• Venting work (new vent pipe, draft hood alignment, chimney connection)
• Gas piping changes (new shutoff, resizing, leak testing)
• Adding a sediment trap on the gas line (often required by code)
• Water piping modifications (new connectors, shutoff valve, expansion tank)
• Drain pan and drain routing (especially in finished spaces)
• Permits and inspections (varies by city and state)

Typical labor scenarios (what you are paying for)

Installation scenario	What is included	Typical labor range
Like-for-like replacement	Disconnect old unit, reconnect existing vent and lines, start-up checks	$400 to $700
Moderate updates	Minor vent or piping changes, new shutoff or connectors	$700 to $1,000
Complex install	Significant venting changes, gas line reroute, code upgrades, tight access	$1,000+

Model-specific items to plan for (153339561)

Your Kenmore 153339561 manual calls out key installation areas that can add time if they are missing or need correction.

• Venting setup and clearances
• Gas piping requirements and leak checks
• Sediment trap installation on the gas supply line
• Temperature and pressure relief valve discharge piping

If the temperature and pressure relief valve is leaking or corroded, replacing it during install is common; the relief valve 100108279 is a listed replacement part for this model.

Why it matters

Gas water heater installs are safety-critical. Paying for the right venting, correct gas piping, and proper relief valve discharge routing helps prevent nuisance shutdowns, poor combustion, and water damage.

A Kenmore gas water heater like model 153339561 typically lasts 8 to 12 years. Regular maintenance (especially controlling sediment and keeping the anode rod in good shape) helps the tank last longer and keeps heating performance more consistent; see the owner's manual.

What affects lifespan the most

• Water quality and conductivity: high conductivity can consume the anode rod faster.
• Anode rod condition: replacing a depleted anode can extend tank life.
• Sediment buildup: reduces efficiency and can overheat the tank bottom.
• Ventilation and combustion air: restricted air intake can cause poor combustion and premature failure.
• Operating conditions: heavy daily demand and higher temperature settings increase wear.

Maintenance that extends life on model 153339561

The manual calls out two big longevity items: checking the anode rod and draining sediment.

• Check the anode rod at least annually after the warranty period.
• Drain and flush the tank periodically to remove sediment.
• Keep the burner area and air intake openings clear.
• If the heater is shut down in freezing conditions, drain the tank.

If you need the replacement part, the anode rod 100108660 is a common wear item for this model.

Quick guide: what to expect by age

Water heater age	What we typically see	What to do next
0 to 5 years	Normal operation with basic upkeep	Flush sediment; monitor performance
6 to 10 years	More scale, more wear on gas components	Inspect anode; consider proactive part replacement
11+ years	Higher leak risk and reliability issues	Plan for replacement; watch closely for leaks

Why it matters

A water heater usually fails in one of two ways: loss of heating (burner, pilot, gas control issues) or tank leakage. Maintenance focuses on preventing corrosion and sediment damage so you get the full expected service life.

The most common gas water heater problem is the pilot going out or the burner not staying lit, which leads to no hot water. On Kenmore model 153339561, this is often tied to condensation dripping onto the burner, restricted combustion air, venting issues, or ignition and gas control components.

Most common symptoms we see

• Pilot will not light or will not stay lit
• Burner lights briefly, then shuts off
• “Sizzling” or “frying” noise during operation (condensation on hot surfaces)
• Not enough hot water or water temperature swings
• Occasional smoke odor at initial start-up (brief burn-off)

Quick checks that solve many “no hot water” calls

1. Confirm the tank is completely full before any relight attempt. Water must flow steadily from a hot faucet before gas is turned on.
2. Look for condensation vs. a true leak. After a big hot-water draw, cold refill water can cause heavy condensation; once the tank warms (about 1 to 2 hours), it typically stops.
3. Check combustion air and intake screening. A dirty or clogged air intake screen or blocked flame arrestor openings can cause poor combustion and shutdowns.
4. Check venting and draft. Poor draft or vent problems can cause condensation at the draft hood and unstable burner operation.

Common causes and what they point to

What you notice	Most likely cause	What to do next
Pilot goes out after burner runs	Condensation dripping onto burner or pilot	Follow condensation guidance in the owner's manual and verify venting and air supply
Pilot will not stay lit	Thermocouple/TCO issue or gas control issue	Inspect pilot flame contact and wiring; replace failed ignition parts as needed
Rumbling or popping	Sediment or calcium in tank bottom	Flush tank per maintenance guidance; consider anode condition
Water at fittings/valves	Loose connection or valve seepage	Tighten carefully; replace leaking valve if needed

Parts that commonly relate to these problems (model 153339561)

• If ignition is weak or intermittent: water heater igniter 100109221
• If the pilot assembly is failing: water heater pilot assembly 100109295
• If the burner is damaged or not burning correctly: water heater burner assembly 100109201
• If the T&P valve is dripping or leaking: relief valve 100108279

Why it matters

Pilot outages, poor combustion, and venting problems can stop hot water fast and can also create condensation that looks like a tank leak. Correct diagnosis prevents unnecessary part replacement and helps keep the burner and venting system operating safely and efficiently.
