Jenn-Air JGS1450FP0 gas slide-in range Parts

Yes. On the Jenn-Air gas range model JGS1450FP0, the oven burner must be ignited to heat, and that ignition is normally done by an electric igniter (not a match). If the igniter is weak or not glowing, the oven typically will not light or will heat poorly.

How oven ignition works on this range

Most modern gas ovens use a hot-surface igniter system:

• You set Bake or Broil on the control.
• The igniter heats up and draws electrical current.
• Once the current is high enough, the gas valve opens.
• Gas flows to the burner and lights off the hot igniter.

A common replacement part for ignition problems is the range oven igniter WPW10324262.

Signs the oven is not igniting correctly

If you are troubleshooting “won’t heat” or “takes forever to preheat,” look for these symptoms:

• No glow from the igniter when Bake is turned on
• Igniter glows but the burner never lights
• Burner lights after a long delay (often 60 to 90 seconds or more)
• Oven temperature is low or inconsistent
• Gas smell with no ignition (turn the oven off and ventilate)

Quick checks you can do safely

Before replacing parts, we recommend these basic checks:

• Confirm the range has power (clock/display on, breaker not tripped).
• Make sure the gas supply valve is fully open.
• Try Broil; if Broil works but Bake does not, the bake igniter is a top suspect.
• Watch through the oven bottom vents for igniter glow during a bake cycle.
• If the cooktop clicks continuously or acts erratically, ignition electronics may be involved (for cooktop ignition, not the oven).

What typically fixes it (and what it points to)

What you observe	Most common cause	Typical fix
No igniter glow	Failed igniter or wiring issue	Inspect connections; replace igniter
Igniter glows, no flame	Weak igniter or gas valve issue	Replace igniter first; then test gas valve
Slow ignition	Weak igniter	Replace igniter

If you suspect a gas valve problem, the gas valve W11163975 is the model-matched part to check.

Why it matters

A gas oven that does not ignite reliably can lead to no-heat cooking failures, long preheat times, and unsafe gas odor conditions. Restoring proper ignition protects performance and helps the burner light quickly and cleanly.

Converting from an electric range/oven to a gas range typically costs $400 to $2,000 total, mainly driven by whether a gas line must be added or extended and whether a 240V outlet needs to be changed. For a gas range like model JGS1450FP0, the biggest cost is usually the gas hookup work.

What drives the price

• Gas line availability: Adding a new gas line or extending one is usually the largest variable.
• Electrical changes: Many gas ranges still need 120V power for the control board, igniters, and oven light; converting from a 240V-only setup can add labor.
• Ventilation: You may need a new or upgraded range hood or ducting.
• Permits and inspection: Common for gas piping work.
• Appliance cost: The range itself is often separate from installation.

Typical cost breakdown (common ranges)

Item	Typical cost range	Notes
Gas line install/extension	$200 to $1,500	Depends on distance, access, and local code
Basic gas range hookup	$100 to $300	Connection, leak test, leveling
Electrical outlet changes	$100 to $400	Converting to a standard 120V receptacle if needed
Venting upgrades	$0 to $800+	Recirculating vs ducted, cabinet work
Permits/inspection	$0 to $300+	Varies by location

What we recommend before you schedule the conversion

• Confirm you have natural gas or propane (LP) available and which your home uses.
• Measure the opening and verify clearances for the new range.
• Plan for a shutoff valve location that is accessible.
• Budget for a qualified installer to connect gas and perform a leak test.
• If you’re moving to a gas range, keep key service parts in mind (for example, ignition and controls) such as the gas valve W11163975 and spark module (red) WPW10475149 used on model JGS1450FP0.

Why it matters

Gas conversions are mostly about safe fuel delivery and proper ignition. A correct gas hookup, shutoff valve placement, and leak testing help prevent ignition problems, weak burner flames, and unsafe operation.

On the JGS1450FP0 gas range, the most common reasons the oven will not ignite are a weak or failed oven igniter, a gas supply issue, or a control problem that is not sending power to the igniter. Start by confirming gas is on, then watch and listen for igniter glow or clicking during a bake start.

Quick checks we recommend first

• Make sure the range gas shutoff valve is fully open.
• Confirm other gas appliances in the home work normally.
• Set Bake and raise the temperature; wait 30 to 60 seconds and watch for igniter activity.
• If you smell gas but no ignition happens, turn the oven off and ventilate the area.
• If the oven is completely dead (no display or response), focus on power and controls first.

What the symptoms usually mean

What you observe	Most likely cause	What to do next
Igniter does not glow (no heat)	Failed igniter, wiring issue, or control not sending power	Inspect wiring connections; test igniter circuit; consider replacing the igniter
Igniter glows but burner never lights	Weak igniter (common)	Replace the igniter
Burner lights sometimes, sometimes not	Weak igniter, intermittent connection, or valve issue	Check harness connections; replace igniter if inconsistent
No oven ignition and surface burners also act abnormal	Gas supply or regulator/valve issue	Confirm supply pressure and shutoff; check valve/regulator components

Parts that commonly fix “oven not igniting”

For this model, these parts are frequently involved in ignition problems:

• Range oven igniter WPW10324262 (bake ignition)
• Range oven burner igniter WPW10333842 (burner ignition circuit)
• Gas valve W11163975 (gas flow control to the oven burner)
• Oven control W11297271 (sends power to ignition and manages bake functions)

Why it matters

A gas oven that will not ignite is often caused by an igniter that is too weak to open the gas valve reliably. Replacing a weak igniter restores normal bake ignition, improves preheat performance, and helps prevent repeated “gas smell but no flame” situations.
