Why is my gas oven not igniting when I turn it on?
On your Jenn-Air PRG4810LP gas freestanding range, the oven uses a pilotless electric glow igniter and safety system; if the igniter is not heating properly or the range has no power, the bake or broil burner will not light (it normally lights within about 30 seconds). Use the checks below to pinpoint whether this is a power, ignition, or gas-supply issue.
Quick checks we recommend first
- Confirm the range is plugged in and has power; this oven will not operate during a power failure.
- Set the oven control fully to OFF, then try again.
- Wait up to 30 seconds after turning the oven on; glow-igniter systems do not light instantly.
- If you smell gas, turn the oven OFF and wait 5 minutes for the odor to clear before trying again.
- If the range was recently installed, disconnected, or unused for several days, air in the gas line can delay ignition.
Most common causes (and what to do)
| Symptom | Most likely cause | What we do next |
|---|---|---|
| No heat, no ignition, display or controls dead | No power to range | Check breaker, outlet, and cord connection |
| Oven won’t light but range has power | Weak or failed glow igniter | Inspect igniter operation; replace if not heating correctly |
| Repeated clicking or ignition issues on top burners too | Ignition circuit issue | Check/replace ignition components |
| Delayed ignition after gas work or long downtime | Air in gas line | Purge air per safe lighting guidance in the owner's manual |
Parts that commonly fix ignition problems
If troubleshooting points to an ignition failure, these model-matched parts are commonly involved:
- Igniter WP73001283 (oven ignition source)
- Reignition module WP73001323 (controls spark/ignition functions)
- Range igniter switch WP73001321 (switching for ignition circuit)
Why it matters
A glow-igniter safety system is designed to prevent gas flow unless ignition conditions are correct. When the igniter is weak or power is interrupted, the safety system keeps the gas valve from opening, so the oven will not light.

How to turn on Jenn-Air stove gas?
To turn on the gas burners on your Jenn-Air PRG4810LP range, make sure the range is connected to the gas supply, then push in the burner knob and turn it to the Lite/ignite position until the burner lights; adjust the flame to fit the pan.
Steps to light a surface burner
- Place cookware on the grate before lighting.
- Push the burner control knob in.
- Turn the knob to the Lite/ignite position to start sparking.
- When the burner lights, turn the knob to your desired flame setting.
- Adjust the flame so it does not extend beyond the edge of the cookware.
- If the burner does not light within a few seconds, turn the knob Off, wait for gas to clear, then try again.
If you smell gas
If you smell gas, do not try to light any appliance and do not touch electrical switches. Follow the safety instructions in the installation guide for what to do next.
Common “won’t light” causes on PRG4810LP
If the knob is turned correctly but the burner will not ignite, these are the most common issues we see:
- Food spill or moisture blocking the burner ports
- Burner cap not seated correctly after cleaning
- Weak or no spark from a failed igniter
- A problem in the ignition circuit (switch or module)
- Gas supply shutoff valve not fully open
Parts that often fix ignition problems
| Symptom | What to check | Example part for PRG4810LP |
|---|---|---|
| No clicking/sparking on any burner | Ignition power and ignition module | Reignition module WP73001323 |
| Clicking but one burner will not light | Burner igniter and switch | Igniter WP73001283 |
| Spark happens only when knob is in certain spots | Switch behind the knob | Range igniter switch WP73001321 |
Why it matters
Correct lighting and flame adjustment helps prevent soot, reduces wasted fuel, and avoids overheating cookware and grates. The manual also notes that flames should be adjusted so they do not extend beyond the cookware edge.

Can I manually ignite my gas oven?
No. On the Jenn-Air PRG4810LP gas range, the oven uses a pilotless (electric) glow ignitor and safety system, so the oven will not operate during a power failure or if it is unplugged. Do not attempt to manually light the oven; use the surface burners only if you can light them safely.
What to do during a power outage
- Keep the oven control in OFF.
- Do not try to bypass the ignition system with a match or lighter.
- If you smell gas, turn all knobs OFF, ventilate the area, and do not create sparks.
- If you need to cook, use an alternate safe method until power is restored.
- Review the safety and operation notes in the PRG4810LP owner's manual.
Why the oven cannot be match-lit on this model
Your PRG4810LP oven is designed to light gas through an electric glow ignitor and a safety system. Without electricity, the ignitor and safety controls do not function, so the oven is designed to stay off.
Parts that commonly affect oven ignition (when power is available)
If the oven will not ignite even with power on, these parts are commonly involved:
Quick comparison: symptom vs likely area to check
| Symptom | What it often points to | Example part on this model |
|---|---|---|
| No clicking or ignition activity | Ignition circuit or switch issue | Range igniter switch |
| Weak or no ignition at burner | Failed igniter | Igniter |
| Multiple burners/oven ignition problems | Control module issue | Reignition module |
Why it matters
Trying to manually light an oven that is designed for electronic ignition can allow unburned gas to accumulate and create a flash or fire risk. Using the built-in safety design protects your home and helps prevent damage to the range.
