Jenn-Air JGS1450DS0 gas range Parts

On your Jenn-Air JGS1450DS0 gas range, a bad igniter usually shows up as no ignition (no flame) or very delayed ignition even though the control is calling for heat. If the igniter does not spark or the burner never lights, the igniter circuit or related parts need attention; use the JGS1450DS0 installation guide for the model’s ignition checks.

• Turn the control to an ignition setting and listen for rapid clicking (spark ignition).
• Watch for a flame within about 4 seconds on surface burners (longer on first use if air is in the gas line).
• If there is no flame: turn the knob to OFF and wait for gas to clear before retrying.
• Confirm the range is plugged into a grounded 3-prong outlet; check the breaker or fuse.
• Confirm the gas shutoff valve is fully open.
• Make sure burner caps are seated correctly and aligned with the igniter electrode.

A weak or failed igniter can prevent proper lighting, which leads to delayed ignition, uneven heating, and repeated sparking. Getting reliable ignition protects cooking performance and reduces nuisance shutdowns.

Replace parts when basic setup checks pass (power, gas, cap alignment) but ignition still fails consistently:

• For surface ignition issues across burners: spark module (red) WPW10475149
• For oven bake ignition or poor oven heating: range oven igniter WPW10324262

Yes. Your Jenn-Air JGS1450DS0 is a gas range, and its oven uses gas for baking and broiling; it lights the burner with an electronic igniter (not a standing pilot). For the exact operating steps and settings, follow the owner's manual.

On the JGS1450DS0, the oven control calls for heat, then the igniter sparks and lights the gas burner. In normal operation, you should see the oven heat up shortly after starting a bake or broil cycle.

• The oven uses gas burners for heat
• Ignition is electronic (spark/igniter), not a pilot flame
• First-time lighting can take longer if there is air in the gas line
• Proper gas type matters (Natural gas vs. LP after conversion)

The installation instructions describe typical ignition timing:

If the oven does not ignite, we use these safe, practical checks first (then stop if the issue continues):

• Make sure the range is plugged into a grounded 3-prong outlet
• Check the circuit breaker or household fuse
• Confirm the gas shutoff valve is fully open
• Turn the oven off, wait briefly, then retry bake or broil
• If ignition still fails, stop and contact Sears PartsDirect support

If you suspect an ignition problem, the range oven igniter WPW10324262 is a common service part for no-heat or delayed-ignition symptoms.

Gas ovens heat quickly and efficiently, but they rely on correct gas supply, proper electrical power for the igniter system, and correct setup for your fuel type (Natural gas or properly converted LP). Using the right procedure helps prevent nuisance no-heat issues.

Common problems we see on Jenn-Air gas ranges like model JGS1450DS0 include burners that will not light, uneven or yellow flames, an oven that will not heat, and cooking results that are off. Many issues trace back to power supply, gas supply, dirty burner ports, or ignition parts.

• Nothing will operate: power cord unplugged, tripped breaker, or blown fuse.
• Surface burners will not light: knob not set correctly, air in gas lines, or clogged burner ports.
• Flames are uneven, yellow, or noisy: burner ports need cleaning, or the range is not set up correctly for the gas supply.
• Oven will not heat or heats inconsistently: ignition or gas delivery issue; bake ignition is a frequent culprit.
• Convection fan seems “not working”: on this style of range, the fan typically starts about 5 minutes into the convection cycle.

1. Confirm the range is plugged into a grounded 3-prong outlet and the breaker is on.
2. Verify the main gas shutoff valve is fully open (see the installation guide).
3. For a first-time hookup or after a gas interruption, run a surface burner for 30 to 60 seconds to purge air.
4. Clean clogged burner ports and make sure burner caps are seated correctly.
5. If the oven will not ignite, inspect the igniter circuit and consider replacing the range oven igniter WPW10324262 if it is weak.

Gas ignition and flame quality affect both cooking performance and safe operation. Addressing power, gas supply, and burner cleanliness first prevents unnecessary part replacement and helps you pinpoint the real failure faster.
