Gas Range Won’t Light or Oven Won’t Ignite? WG02F04373 Hot Surface Ignitor – Fix No-Ignition Fast

If your gas range oven won’t heat, the burner won’t light, or you hear clicking but get no flame, the hot surface ignitor is the most common cause. In most GE, Frigidaire, and Whirlpool gas ranges, the hot surface ignitor draws current to glow hot enough to open the gas valve and ignite the burner — when it weakens or fails, the valve never opens and the oven produces no heat. When it fails, the oven may click repeatedly, glow faintly but not ignite, or produce no response at all. ⚡ Hot surface ignitor failure is the single most common cause of a gas oven that won’t heat. Part WG02F04373 is the genuine OEM ignitor that restores full ignition current, opens the gas valve, and returns normal oven operation immediately.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Gas supply to the range is confirmed on and flowing
• ✔ Stovetop burners light normally (surface ignition is working)
• ✔ Oven clicks or ignitor glows but burner does not light
• ✔ Ignitor draws less than 3.2 amps (weak ignitor — won’t open valve)
• ✔ ONLY problem is oven not heating — not a gas valve, control board, or thermostat fault

🔧 Common Symptoms

• Oven won’t heat — no ignition, no flame
• Ignitor glows orange but burner never lights — weak ignitor not drawing enough current to open gas valve
• Oven takes extremely long to preheat — ignitor weakening
• Oven ignites intermittently — ignitor failing under load
• Burning smell with no flame — gas released but not ignited
• Ignitor visibly cracked, broken, or not glowing at all

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing the hot surface ignitor restores full oven ignition and normal heating immediately.

⚙️ Installation

Skill Level: Easy to Moderate — 20–40 minutes. Disconnect power and shut off the gas supply before servicing. Access the ignitor by removing the oven bottom panel and burner cover — typically two screws. Disconnect the ignitor wiring harness (do not touch the ignitor element with bare hands — skin oils cause premature failure), remove the mounting screws, and install the new WG02F04373 in the same position. Reconnect the harness, reassemble the oven floor, restore power and gas, and run a preheat cycle to confirm ignition.
