How do I read my water heater model number?
On your Kenmore gas water heater model 153576500, the model number is printed on the rating plate (data sticker) attached to the tank. Match the full model number exactly as shown on that label; you can ignore most other specs on the plate unless you are troubleshooting.
Where to find the model number label
Most gas water heaters place the rating plate on the outside of the tank jacket.
- Look on the side of the tank near the gas control valve area
- Check the front of the tank behind or near the burner access door
- Look for a label that also lists the serial number
- Wipe dust off the label so every digit is readable
For label location and identification details, use the owner's manual.
How to read it correctly (so you get the right parts)
Use the model number exactly as printed, including all digits.
| What to capture | What it’s used for | Example for this unit |
|---|---|---|
| Model number | Ensures parts fit your exact water heater | 153576500 |
| Serial number | Helps identify production run and variations | From the label |
| Brand | Confirms product family | Kenmore |
Common mistakes we see
- Mixing up similar-looking characters (0 vs O, 5 vs S)
- Using only part of the model number
- Reading a number from the gas valve or burner instead of the tank rating plate
Why it matters
Kenmore water heater parts can vary by production run. Using the exact model number helps you select the correct repair parts (such as a pilot assembly, thermocouple, or gas control valve) and avoid returns due to fit issues.

How many years will a gas water heater last?
A tank-style gas water heater typically lasts 8 to 12 years. With consistent maintenance (especially flushing sediment and protecting the tank from corrosion), many units reach 12 to 15 years before performance drops or leaks become likely; see the owner's manual for model-specific care steps.
Typical lifespan ranges (what to expect)
| Water heater type | Typical lifespan | What usually ends it |
|---|---|---|
| Standard tank gas water heater | 8 to 12 years | Tank corrosion, sediment damage |
| Well-maintained tank gas water heater | 12 to 15 years | Wear plus corrosion over time |
What shortens the life of a Kenmore 153576500
- Hard water and heavy sediment buildup in the tank
- High temperature settings (more stress on the tank and controls)
- Skipping annual flushing and inspection
- A depleted anode rod (tank corrodes faster)
- Venting or combustion air issues that cause poor burner operation
Maintenance that extends service life
- Flush the tank at least once per year to reduce sediment.
- Inspect and replace the anode rod when it is heavily worn; the anode rod 100109624 is the sacrificial part that helps protect the tank.
- Test the temperature and pressure relief valve periodically; replace if it will not operate correctly (example part: water heater temperature and pressure relief valve 100108279).
- Keep the burner area clean and make sure the burner access door is properly installed after service.
- Set a reasonable temperature (many homes run around 120°F) to reduce scaling and overheating.
Signs it is near end-of-life
- Rust-colored water or metallic odor that keeps returning
- Rumbling or popping sounds from heavy sediment
- Water around the base of the tank (leak risk)
- Frequent pilot outages or unstable burner operation
- Not enough hot water even after basic maintenance
Why it matters
Once the tank itself starts corroding through, repairs stop being cost-effective because the leak is coming from the tank body, not a replaceable part. Preventive maintenance focuses on sediment control and corrosion protection so your gas control valve, pilot assembly, and tank last as long as possible.

How old is my water heater by the serial number?
To estimate the age of your Kenmore 153576500 gas water heater, we use the serial number on the rating plate and decode it using the manufacturer’s date format (Kenmore units are commonly built by a major water-heater maker, and the format varies). The quickest path is to match your serial pattern to the decoding examples in the owner's manual.
Where to find the serial number
Look for a data label (rating plate) on the outside of the tank. Common locations:
- On the side of the tank near the gas control valve
- Near the burner access door area
- On the upper side panel near the draft hood
- On a label that also lists capacity, gas type, and input BTU
How to decode the serial number (most common formats)
Once you have the serial number, compare it to these common patterns used across major manufacturers:
- YYWW format: first 2 digits = year, next 2 digits = week of the year (example: 1220 = week 20 of 2012)
- MMYY format: first 2 digits = month, next 2 digits = year (example: 0519 = May 2019)
- Letter-based month/year: letters represent month and year; the sequence repeats over time, so you confirm using the model era and label style
Quick pattern check table
| What the serial starts with | What it usually means | Example result |
|---|---|---|
| 4 digits, all numbers | Week/year or month/year | 0721 = July 2021 (MMYY) or week 21 of 2007 (YYWW) |
| Letters then numbers | Letter-coded month/year | Use the letter key, then confirm with the label’s other info |
| Long numeric string | Often contains date in first 4 digits | Start by testing MMYY, then YYWW |
Why it matters
Knowing the build date helps us choose the right repair approach for your 153576500, including whether issues are more likely from normal wear (pilot problems, gas valve wear, tank protection) and which replacement parts are most commonly needed.
If you’re troubleshooting at the same time
Age plus symptoms usually points to a short list of parts:
- Pilot will not stay lit: check the water heater thermocouple 100112327 and water heater pilot assembly 100112330
- Temperature swings or no heat: gas control issues can involve the gas control valve 100262939
- Preventive maintenance for tank life: inspect/replace the anode rod 100109624

What is the most common problem with a gas water heater?
The most common gas water heater problem is a pilot that will not stay lit, which usually traces back to the pilot/thermocouple system or the gas control. On Kenmore model 153576500, start by checking the pilot flame and safety components using the owner's manual.
Most common symptoms (and what they usually point to)
- Pilot goes out repeatedly: weak pilot flame, failing thermocouple, or gas control issues
- No hot water or inconsistent hot water: gas control/thermostat problems or burner issues
- Rumbling, popping, or banging: sediment buildup in the tank
- Water dripping from the relief valve: overheating, high pressure, or a worn relief valve
- Water around the base of the heater: loose fittings or a leaking tank
Quick checks we recommend first
- Confirm gas supply is on and other gas appliances work.
- Look at the pilot flame: it should be steady and strong, not lazy or flickering.
- Inspect the burner area for dust, lint, or restricted airflow.
- Check for signs of overheating/pressure (very hot water, frequent relief valve discharge).
- Listen for sediment noise; flushing the tank often reduces rumbling.
Common parts involved on this model
If troubleshooting points to ignition or safety shutdown, these are the most frequently replaced items for model 153576500:
| Symptom | Likely part area | Example part for this model |
|---|---|---|
| Pilot will not stay lit | Pilot/thermocouple | Water heater thermocouple 100112327 |
| Pilot flame weak or unstable | Pilot assembly | Water heater pilot assembly 100112330 |
| Temperature swings or no heat | Gas control/thermostat | Gas control valve 100262939 |
| Dripping from discharge pipe | Safety relief | Water heater temperature and pressure relief valve 100108279 |
Why it matters
A pilot that will not stay lit is more than an inconvenience; it is the heater’s safety system shutting down heat. Fixing the root cause restores reliable hot water and helps prevent nuisance shutdowns and overheating conditions.
