Possible Causes

Faulty Oven Igniter

How to Identify: Igniter glows weakly, never reaches full brightness, takes long to ignite gas, or gas flame doesn’t light; smell of unburned gas.

Part: Oven Igniter

Clogged Burner Orifice / Restricted Gas Flow

How to Identify: Weak or irregular flame, burner ports appear clogged with debris/grease; oven fails to reach temperature even if igniting occasionally.

Part: Burner Orifice / Gas Path

Control Board Malfunction

How to Identify: No heat despite seemingly proper operation; display errors or unresponsive controls; cycles fail to start.

Part: Control/Relay Board

Damaged Wiring or Connections

How to Identify: Burnt connectors, loose wiring, intermittent operation; oven randomly fails to ignite even with good igniter.

Part: Internal Wiring/Connectors

DIY Solutions

Inspect and Replace Igniter

Moderate 30–60 minutes

Tools Needed: screwdriver, multimeter, replacement igniter

1. Turn off power and gas supply to the oven.
2. Remove oven access panel to locate the igniter.
3. Observe igniter behavior during a heat cycle; test with multimeter for continuity.
4. Replace igniter if it fails to glow properly or has no continuity.
5. Reassemble and test oven heating.

⚠️ Safety First: Ensure gas supply is off before working on components

Clean Burner Orifice and Ports

Moderate 20–40 minutes

Tools Needed: soft brush, compressed air

1. Turn off gas and power to the oven.
2. Remove burner cover/grates to access orifice and ports.
3. Gently clean debris and grease with brush and air.
4. Reassemble and test flame quality.

⚠️ Safety First: Do not enlarge or damage orifice holes
