Jenn-Air JGS1450FS0 gas slide-in range Parts

On the Jenn-Air JGS1450FS0 gas range, a bad oven igniter usually shows up as a bake or broil burner that will not light, lights slowly, or heats unevenly; the igniter may glow weakly or the oven may take several minutes to reach temperature.

Common signs the igniter is failing

• Oven takes much longer than normal to preheat
• Burner clicks or tries to light repeatedly but does not ignite
• Igniter glows dim orange instead of bright yellow-white
• Burner lights sometimes, then fails the next time
• You smell gas briefly because the burner is not lighting promptly

Quick checks you can do (before testing parts)

• Set the oven to Bake and watch through the openings: the igniter should begin glowing within about 30 to 60 seconds.
• If the igniter glows but the burner does not light within about 90 seconds, the igniter is typically too weak to open the gas valve reliably.
• If the igniter never glows, check for a tripped breaker, loose wiring, or a failed igniter.

Best confirmation test: amperage draw

A weak igniter can glow but still fail under load. Using a clamp meter on one igniter lead is the most reliable check.

Igniter behavior	What it usually means	What we recommend
No glow at all	Open igniter, wiring issue, or control issue	Inspect wiring; consider replacing igniter
Glows, but burner will not light (or is very delayed)	Weak igniter (most common)	Replace igniter
Burner lights, but preheat is still slow	Igniter weakening or burner/airflow issue	Check burner ports; replace igniter if symptoms persist

Parts that commonly fix “no heat” on a gas oven

If your symptoms match, these are the most common replacements for this model family:

• Range oven igniter WPW10324262 (common bake ignition failure)
• Range oven burner igniter WPW10333842 (another igniter used on some configurations)
• Gas valve W11163975 (less common; usually replaced only after igniter tests good)

Why it matters

A weak igniter can cause delayed ignition, poor temperature control, and repeated failed lighting attempts. Replacing the igniter early often restores normal preheat time and steadier baking performance.

Most gas stoves, including the Jenn-Air JGS1450FS0 gas range, are designed to run on natural gas (typical home gas line) or propane (LP) when the range is properly converted for LP use. The correct fuel depends on how your home is supplied.

Common fuel types you will see

• Natural gas (NG): Most common for homes with a utility gas line
• Propane (LP): Common for homes with a propane tank
• Butane: Used in some regions and portable appliances (not typical for U.S. full-size ranges)
• LPG (liquefied petroleum gas): A general term that often refers to propane or butane

How to tell which gas your range is set up for

Use these quick checks before you light burners or troubleshoot ignition:

• Look at your home supply: gas meter (usually NG) or propane tank (LP)
• Check the flame: steady blue flame is normal; large yellow flames often point to an air or fuel setup issue
• If you recently moved or changed fuel type, confirm the range was converted to match
• If burners click but do not light consistently, the issue is often ignition-related, not fuel type

Parts that are often involved when ignition problems look like “wrong gas”

Fuel type problems and ignition problems can feel similar. On the JGS1450FS0, these parts are commonly checked during diagnosis:

Symptom	Common area to check	Example part for this model
Oven will not ignite or takes too long	Oven igniter circuit	Range oven igniter WPW10324262
Surface burners keep clicking or spark is weak	Spark ignition system	Spark module (red) WPW10475149
Oven burner ignition is inconsistent	Burner igniter	Range oven burner igniter WPW10333842

Why it matters

Using the correct gas type and proper conversion protects cooking performance and helps prevent hard ignition, soot, and uneven flames. If your home is LP and the range is still set for NG (or vice versa), the burners and oven can behave unpredictably.

If your Jenn-Air gas range model JGS1450FS0 oven is not igniting, the most common causes are a weak or failed bake igniter, a gas supply issue, or a control or wiring problem. Start by checking for igniter glow, gas odor, and error symptoms, then test the ignition components.

Quick checks (safe, no tools)

• Confirm the range is getting power (clock/display on); the igniter needs electricity to heat.
• Make sure the gas shutoff valve is fully open and other gas appliances work.
• Set BAKE and watch through the oven bottom vents: the igniter should glow within about 30 to 90 seconds.
• If you smell gas but no ignition happens, stop the cycle, ventilate the area, and do not keep retrying.
• If the igniter glows but the burner never lights, the igniter is typically too weak to open the gas valve.

What the symptoms usually mean

What you see	Most likely cause	What to check next
No glow from igniter	Failed igniter, wiring, control	Inspect connections; consider replacing igniter
Igniter glows, no flame	Weak igniter (common)	Replace igniter
Ignites sometimes	Weak igniter, loose connection	Check harness plugs; replace igniter if intermittent
Surface burners work, oven does not	Oven ignition circuit issue	Igniter, oven control, wiring

Parts that commonly fix “won’t ignite” on JGS1450FS0

• Range oven igniter WPW10324262: common fix when there is no ignition or the igniter is weak.
• Range oven burner igniter WPW10333842: another oven igniter used on this model; match by location and wiring style.
• Gas valve W11163975: less common; suspect if igniter is proven good but gas never flows to the bake burner.
• Oven control W11297271: suspect if the igniter never gets power and wiring checks good.

Why it matters

A gas oven that will not ignite can indicate a weak igniter that is allowing delayed ignition attempts, uneven heating, or no heat at all. Fixing the ignition system restores normal bake performance and helps prevent repeated gas buildup from failed starts.
