BlueStar Oven Won’t Ignite or Reach Temperature? Oven Ignitor 703308 – Restore Reliable Ignition Fast
A BlueStar gas range oven that won’t ignite, takes too long to heat, or never reaches the set temperature almost always has a failed bake ignitor. In most BlueStar gas ranges, the oven ignitor is the only component that opens the gas valve and lights the burner — when its resistance drifts out of spec or the element cracks, the valve won’t open and the oven won’t light. When it fails, you get no ignition, a gas smell without flame, or an oven that glows but never fires. ⚡ The bake ignitor is the most common cause of oven ignition failure in BlueStar gas ranges. Part 703308 is the genuine OEM replacement that restores fast, reliable oven ignition immediately.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Your range is a BlueStar gas model with a bake ignitor-controlled oven burner
- ✔ Gas supply is confirmed on — surface burners light normally
- ✔ The oven ignitor glows orange/red but the burner never fires, OR the ignitor doesn’t glow at all
- ✔ ONLY problem is oven won’t ignite, won’t heat, or takes excessively long to reach temperature

🔧 Common Symptoms
- Oven won’t ignite — no flame, no heat
- Ignitor glows orange but gas valve never opens and burner doesn’t light
- Oven takes excessively long to preheat — weak ignitor draw
- Oven won’t reach set temperature — cycles off before heating fully
- Gas smell in oven cavity without ignition
- Ignitor doesn’t glow at all when oven is set
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing the bake ignitor restores full oven ignition and heating immediately.
📦 Part Details
- Part Number: 703308
- Type: Gas Range Oven Bake Ignitor — hot surface ignitor, OEM BlueStar
- Replaces: 703304 — direct drop-in, no modification required
- Brands: BlueStar
While the oven bottom is out, inspect the bake burner orifice and gas valve for debris or corrosion. A partially blocked orifice causes the same slow-heat symptoms as a weak ignitor and is easy to clean during the same visit. If the ignitor glowed but the valve never opened, the gas valve itself may also need replacement.
⚙️ Installation
Skill Level: Moderate — 30–45 minutes. Turn off gas supply and disconnect power before servicing. Remove the oven racks and oven bottom panel to access the bake ignitor. Disconnect the ignitor wire harness, remove the mounting screws, and install the new 703308. Reconnect the harness, reinstall the oven bottom, restore gas and power, and test ignition by setting the oven to 350°F — the ignitor should glow and the burner should light within 90 seconds.
💡 Pro Tip
A healthy BlueStar bake ignitor draws 3.2–3.6 amps at 120V. Set your multimeter to measure resistance — a good ignitor reads 40–90 ohms. If yours reads open (OL) or above 200 ohms, it’s confirmed failed and 703308 is the correct fix. This 60-second test eliminates guesswork and confirms the ignitor — not the gas valve — is the fault.
