Kenmore 153331682 water heater Parts

For Kenmore gas water heater model 153331682, you can date the unit by decoding the serial number format: older units use a month letter plus a 2-digit year, while newer units use an 11-character serial where the first two digits are the year and the next two digits are the week.

Step 1: Find the serial number in the right place

You’ll typically find the serial number on the rating plate label on the tank. Use the owner's manual to confirm the exact label location and how the serial is formatted for your unit.

Step 2: Decode the serial number format

Use the format that matches what you see on your label.

• If the serial number has letters and looks like an older style (pre-2008):
  • The 2nd character is a month letter.
  • The next two digits are the year.
  • Month letters run A through N for Jan through Dec, skipping I.
• If the serial number is an 11-character alpha-numeric style (2008 and newer):
  • The first two characters are the year.
  • The next two characters are the week number (01 to 52).

Month letter quick reference (older serial numbers)

Month	Letter
Jan	A
Feb	B
Mar	C
Apr	D
May	E
Jun	F
Jul	G
Aug	H
Sep	J
Oct	K
Nov	L
Dec	M or N

Example (so you can sanity-check your result)

Serial style	What to read	Example meaning
Month letter + year	2nd character = month, next 2 digits = year	B07 = Feb 2007
11-character year + week	first 2 = year, next 2 = week	14 23 = week 23 of 2014

Why it matters

Knowing the manufacture date helps you plan maintenance and repairs, especially for common wear items like the anode rod 100109624 and safety components such as the water heater temperature and pressure relief valve 100108279. It also helps you decide whether a no-heat issue is more likely a maintenance problem (burner and pilot) or a control issue.

The most common gas water heater problem is not getting enough hot water (slow recovery or water that stays lukewarm). On Kenmore model 153331682, the most common causes are restricted combustion air, a blocked vent/flue, low gas pressure, or a lint-clogged base-ring filter; see the owner's manual.

Most common symptoms you will notice

• Hot water runs out faster than normal
• Water never reaches the set temperature
• Burner seems to run longer than usual
• Pilot goes out intermittently
• Sooting or unusual odors near the draft hood

What usually causes it on model 153331682

The manual points to airflow and venting issues as top drivers of poor heating performance. Start with these checks:

• Combustion air is restricted (tight closet, blocked make-up air openings, negative pressure from exhaust fans)
• Base-ring filter is dirty (lint, dust, dirt buildup at the bottom of the heater)
• Flue or venting is blocked or deteriorated (can cause improper venting and poor combustion)
• Gas supply issues (low gas pressure or supply problems)
• Control or ignition components are failing (pilot, thermocouple, gas valve/temperature control)

Quick triage: what to check first (in order)

1. Confirm the area has adequate fresh air and nothing is blocking airflow around the heater.
2. Inspect the venting path for obstructions, loose connections, or rust flakes.
3. If the installed environment is dusty, clean the base-ring filter and surrounding intake area.
4. If the pilot will not stay lit, inspect ignition components and wiring connections.

Parts that commonly fix “no heat” or “pilot won’t stay lit”

Symptom	Common suspect	Example part for 153331682
Pilot won’t stay lit	Thermocouple or pilot assembly	Water heater thermocouple 100112327 or water heater pilot assembly 100112330
Burner will not fire or temp control issues	Gas valve/temperature control	American water heaters water heater gas valve and temperature control assembly 100112336
Slow recovery in dusty area	Clogged intake/filter base area	Filter base 100111375

Why it matters

A gas water heater needs clean airflow and proper venting to burn fuel correctly. When air supply is restricted or venting is blocked, the flame can burn poorly, heat can build up in the combustion chamber, and safety devices can trip, leaving you with little or no hot water.

Yes. On the Kenmore 153331682 gas water heater, many service parts are replaceable (such as the gas control, pilot components, and valves) as long as you follow the safety steps and procedures in the owner's manual and shut off gas and water before starting.

Parts you can commonly replace on this model

These are typical replaceable items for the Kenmore 153331682, and several are available for this model:

• Water heater pilot assembly 100112330 (pilot ignition and flame sensing components)
• American water heaters water heater gas valve and temperature control assembly 100112336 (gas control and temperature regulation)
• Water heater temperature and pressure relief valve 100108279 (safety pressure relief)
• Water heater drain valve 100108778 (tank draining and flushing)
• Anode rod 100109624 (corrosion protection)

Safety first (gas water heater essentials)

We recommend these steps before any inspection or part replacement:

• Turn the gas control/temperature knob to OFF and wait at least 10 minutes before attempting relighting.
• Shut off the cold water supply valve to the heater.
• If you smell gas: do not operate switches or phones nearby; follow the safety instructions on the heater.
• Keep combustion air openings clear; do not store flammables near the heater.
• If the gas control knob will not turn by hand, stop and use a qualified technician.

Quick guide: which part matches which symptom?

Symptom	Most likely area	Example part on this model
Pilot will not stay lit	Pilot flame, wiring, safety sensing	Water heater pilot assembly 100112330
No burner operation, status light codes	Gas control/temperature control	American water heaters water heater gas valve and temperature control assembly 100112336
Water leaking from relief valve discharge pipe	T&P valve or overheating condition	Water heater temperature and pressure relief valve 100108279
Hard to drain or drain valve drips	Drain valve	Water heater drain valve 100108778

Why it matters

Replacing the correct part restores safe operation and helps prevent nuisance shutdowns, leaks, and overheating. On gas water heaters, correct venting and combustion air are just as important as the replacement part itself.

A Kenmore gas water heater like model 153331682 is built around the tank plus a gas burner system, safety controls, and water connections. Common service parts include the pilot assembly, gas control valve/thermostat, burner access door, drain valve, anode rod, and the temperature and pressure relief valve (T&P).

Main parts you will typically find

These are the components customers most often ask about on a gas tank water heater:

• Tank (stores and heats water)
• Gas control valve/thermostat (regulates gas flow and water temperature)
• Pilot and ignition components (light and prove flame)
• Burner and manifold (mix and deliver gas to the burner)
• Draft hood and venting (moves combustion gases safely up the flue)
• Anode rod (helps protect the tank from corrosion)
• Drain valve (used for draining and flushing sediment)
• Temperature and pressure relief valve (T&P) (critical safety valve)

Model 153331682 parts you can replace

For this Kenmore model, these are examples of replaceable parts we commonly see on the parts list:

• Water heater pilot assembly 100112330
• American water heaters water heater gas valve and temperature control assembly 100112336

Quick “what it does” reference

Part	What it does	Common reason to replace
Pilot assembly	Lights the burner and supports safe operation	Pilot will not stay lit, weak pilot flame
Gas valve/thermostat	Controls gas flow and temperature	No heat, temperature problems
T&P relief valve	Releases excess pressure/temperature	Dripping, leaking, won’t reseat
Anode rod	Reduces tank corrosion	Odor issues, heavy corrosion, routine maintenance
Drain valve	Drains tank for flushing	Leaks, clogged, won’t open/close

Why it matters

Knowing the major parts helps you troubleshoot safely and order the correct replacement. For example, the manual calls out proper gas piping practices (shut-off valve, union, drip leg) and leak-checking with an approved solution, which directly affects safe operation.
