Viking Oven: not heating; igniter issues
What is this symptom?
Is your Viking oven turning on but not heating? If the igniter glows weakly or fails to ignite the burner, it may indicate issues with the hot surface igniter, which could be too weak or completely failed. This problem can lead to frustrating cooking experiences as the oven may intermittently heat or not heat at all. Discover the common causes and solutions to get your oven back in working order.
Important Tips for Viking Models
- Viking gas ovens commonly use glow-bar style hot surface igniters; weak igniters are a leading cause of 'won’t heat' complaints. A commonly referenced igniter part number family is PB040001 / 065650-000 (exact compatibility depends on model/series). If your igniter glows longer than ~90 seconds without flame, replacement is strongly indicated.
Possible Causes
Weak hot surface igniter (glows but does not open gas safety valve)
How to Identify: Igniter glows but burner does not light within ~90 seconds; may take a long time to ignite; flame may never start; igniter glow may look dull orange instead of bright yellow-white. Oven may work intermittently.
Part: Hot surface igniter / glow bar igniter (often Viking PB040001 / 065650-000 equivalents depending on model)
Failed/open hot surface igniter (no glow at all)
How to Identify: No igniter glow when bake is selected; no burner ignition; testing shows no continuity across igniter leads (open circuit.
Part: Hot surface igniter / glow bar igniter
Defective gas safety valve (oven valve) not opening even with a functioning igniter
How to Identify: Igniter glows bright and normally, but burner still does not ignite; igniter tests good and draws correct current (requires clamp meter test; no gas flow to burner despite correct voltage present.
Part: Oven gas safety valve / gas valve
Burner/igniter area obstruction, misalignment, or heavy residue preventing reliable ignition
How to Identify: Igniter glows but ignition is delayed or inconsistent; visible debris/grease near burner ports; igniter not positioned correctly near burner; symptoms may improve after cleaning.
Part: Oven burner tube, igniter mounting position, flame spreader/shield
Control board or wiring issue preventing voltage from reaching igniter
How to Identify: Igniter does not glow, but igniter tests good for continuity; no voltage delivered to igniter when bake is selected (requires meter and wiring diagram; may see signs of board damage.
Part: Oven control board (ERC), wiring harness, connectors
DIY Solutions
Confirm igniter behavior (glow test) and diagnose weak vs. dead igniter
- Turn off power to the oven at the breaker for safety before removing any panels.
- Remove the oven bottom panel and/or flame spreader/shield to view the igniter and burner tube (layout varies by Viking model).
- Restore power, set oven to BAKE, and observe: (a) no glow at all, or (b) glow present but no ignition within ~90 seconds.
- If the igniter glows but burner does not ignite within ~90 seconds, treat it as a weak igniter (most common). If there is no glow, proceed to continuity testing (next solution).
Replace a weak or failed hot surface igniter (glow bar igniter)
- Shut off power at the breaker and shut off the gas supply valve to the range/oven.
- Access the igniter by removing the oven racks and oven bottom panel/flame spreader.
- Disconnect the igniter wiring connector if your model has a plug; if it is hardwired, cut and splice using high-temperature ceramic wire nuts (never use standard plastic wire nuts in the oven cavity).
- Remove igniter mounting screws and install the new igniter in the same position (do not touch the igniter element with bare fingers if possible).
- Reassemble panels, restore gas and power, and test BAKE. The burner should ignite typically within ~30–60 seconds (and not exceed ~90 seconds).
Continuity test the igniter (for no-glow condition)
- Turn off power at the breaker and shut off gas for safety.
- Access the igniter and disconnect it from the wiring harness (or isolate leads if hardwired).
- Set the multimeter to continuity or resistance mode and measure across igniter leads.
- If the igniter shows no continuity (open circuit), replace it.
Clean and inspect burner tube/igniter area for debris and ensure proper alignment
- Turn off power and allow the oven to cool completely.
- Remove the oven bottom panel/flame spreader to expose the burner tube and igniter.
- Brush away food debris/grease accumulation and confirm the igniter is securely mounted and positioned close to the burner as originally designed.
- Reassemble and test for improved ignition consistency.
Professional Repairs
Measure igniter amperage draw and replace igniter if below spec
Replace oven gas safety valve (gas valve) after confirming igniter is good
Diagnose and repair control board / wiring fault preventing power to igniter
When to Call a Professional
Preventive Maintenance
-
Keep the oven bottom and burner area free of heavy spillovers and baked-on debris (clean after major spills once the oven is cool).: Delayed ignition, poor flame carryover, and ignition inconsistency
Frequency: as needed (check monthly if used frequently) -
Avoid slamming oven racks/pans into the oven floor and igniter area.: Igniter cracking and premature igniter failure
Frequency: ongoing

Can I Fix This Myself?
Common Issues Reported by Users
- Faulty igniter not reaching the required temperature to open the gas valve
- Defective gas valve preventing gas flow to the burner
- Electrical issues, such as faulty wiring or a malfunctioning control board
User Suggested Solutions
-
Inspect the igniter for cracks or damage. If faulty, replace the igniter. To replace, disconnect power, remove the oven bottom panel, disconnect the old igniter, and install the new igniter. Reassemble and test the oven.
-
Check the gas valve for functionality. If it is defective, replace it. This involves disconnecting the gas supply, removing the old valve, and installing a new one. Ensure all connections are secure and leak-tested.
-
Inspect electrical connections and wiring for any signs of damage. If the control board is malfunctioning, it may need to be replaced. This requires disconnecting power, removing the control panel, and swapping out the board.
