Kenmore 153331543 water heater Parts

For Kenmore gas water heater model 153331543, the model number is printed on the rating plate (model rating plate) on the front of the tank. We use that exact model number to match the correct parts list, owner’s manual, and service information.

Where to find the model number on the heater

Look for a rectangular label on the tank called the rating plate.

• Check the front of the water heater first (most common location)
• Look for fields labeled MODEL NO. and SERIAL NO.
• Write the model number exactly as shown (for example, 153331543)
• Take a clear photo of the rating plate before ordering parts
• Keep the serial number too; it helps identify production details when troubleshooting

What to pay attention to (and what to ignore)

The rating plate includes a lot of technical data. For parts lookup, the model number is the key.

Rating plate item	Use it for	Priority
Model number (MODEL NO.)	Matching parts and diagrams	Highest
Serial number	Identifying production run details	Medium
BTU input, gas type, pressures	Setup and service checks	Lower

Why it matters

Kenmore gas water heaters often have similar-looking tanks across different gallon sizes and configurations. Using the exact model number (like 153331543) prevents ordering the wrong burner, pilot, or gasket and helps us point you to the correct troubleshooting steps in the manual.

Helpful references

• Use the 153331543 owner's manual to confirm rating plate location and label wording.
• If you’re diagnosing a control or status light issue after identifying the model, use Kenmore gas water heater error codes.

A Kenmore gas water heater like model 153331543 typically lasts 8 to 12 years. With correct venting, proper gas combustion, and routine maintenance (especially tank flushing and anode rod checks), many units reach the upper end of that range; heavy sediment and corrosive water shorten it.

What affects life expectancy most

• Water quality (hard water and high mineral content increase sediment)
• Maintenance frequency (flushing helps prevent overheating and tank damage)
• Anode rod condition (a consumed anode speeds up tank corrosion)
• Combustion and venting (poor draft can cause sooting and burner problems)
• Operating temperature (higher setpoints increase stress on the tank)

Quick “repair vs. replace” guide

What you’re seeing	Most likely meaning	Typical next step
Rusty water or metallic smell	Anode rod is depleted	Inspect and replace the anode rod
Rumbling or popping	Sediment buildup in tank	Flush tank and evaluate recovery
Pilot won’t stay lit	Pilot/thermocouple or combustion air issue	Inspect pilot system and burner area
Water around base of tank	Possible tank leak	Plan for replacement

Parts that commonly extend service life

For Kenmore model 153331543, these parts are often involved in longevity-related repairs:

• Anode rod 100108660 (sacrificial corrosion protection for the tank)
• Pilot assembly 100109293 (keeps the burner safely lit)
• Water heater burner assembly 100109281 (restores proper combustion and heating)

Why it matters

Once a tank begins leaking, replacement becomes the practical path. Catching issues early, especially a worn anode rod or heavy sediment, helps you avoid sudden loss of hot water and reduces the chance of tank failure.

For maintenance intervals, safety precautions, and model-specific guidance, follow the 153331543 manual.

You can tell the manufacturing year of your Kenmore gas water heater model 153331543 by finding the serial number on the rating plate and decoding it using the format used by the manufacturer that built the tank. The quickest path is to match the serial format shown on the label to the decoding guidance in the 153331543 owner's manual.

Where to find the serial number (and what to write down)

We recommend copying the information exactly as it appears on the rating plate on the front of the water heater.

• Model number: 153331543
• Serial number: copy all letters and numbers in order
• Gas type: natural gas or propane (LP)
• Any additional code lines on the label (sometimes used for date coding)

How serial number date codes are commonly formatted

Kenmore-branded water heaters were built by different manufacturers over the years, so the serial number format is not universal. These are the most common patterns you will see:

• YYWW: first 2 digits are the year, next 2 digits are the week (example: 1220 = week 20 of 2012)
• MMYY: first 2 digits are the month, next 2 digits are the year (example: 0915 = September 2015)
• Letter + numbers: a letter may represent the month, followed by a year code (varies by maker)
• Embedded date: the date is in the middle of the serial number, not at the start

Quick comparison table

What you see in the serial number	Usually means	Example decode
Starts with 4 digits	Date is likely at the beginning	0915 = Sep 2015
Starts with 2 digits then 2 digits	Year then week is common	1220 = week 20 of 2012
Starts with a letter	Month or plant code may be used	Letter-based month code

Why it matters

Knowing the manufacturing year helps us choose the right repair approach and parts for your Kenmore 153331543, especially for ignition and combustion components (pilot, burner, gasket) where designs can change over time.

If you are ordering parts

When ordering repair parts, we use the model and serial number together to ensure the best match.

• Have the model and serial number ready
• Confirm whether the unit is natural gas or LP
• Match parts by description and fit
