Viking Oven Not Heating
A Viking oven that won't heat is frustrating — especially on a high-end range where a service call starts at $200. The good news: most Viking no-heat failures follow one of three clear paths depending on whether you have a gas, electric, or dual-fuel model. Gas ranges almost always trace back to a weak or failed igniter (~55% of no-heat calls). Electric and dual-fuel ovens usually point to a burned-out bake or broil element, or a failed temperature probe (RTD). This guide walks you through each path with specific resistance specs and fault codes for Viking's most popular models: VGSO5304BSS, VGIC53616BSS, VDOE530SS, VESO5272BSS, and VWO5272BSS.

Common Symptoms
- Oven does not heat at all when set to Bake or Broil
- Gas burners light normally but the oven cavity stays cold
- Bake works but Broil does not (or vice versa)
- Display shows fault code F1, F3, or F6
- Igniter glows orange but the burner does not light after 2+ minutes
- Convection fan runs but oven temperature never rises
- Oven heats unevenly or undershoots the set temperature by more than 25°F
Most Likely Causes
- 1
Weak or Failed Gas Igniter (Most Common — ~55% of Gas No-Heat Calls)
Viking gas ovens use a hot-surface igniter that must draw 3.2–3.6 amps to open the gas safety valve. A weak igniter draws less current, glows orange indefinitely, but never opens the valve — so gas never flows and the burner never lights. If the igniter glows for more than 2 minutes without the burner igniting, the igniter is failing even though it looks functional. Replacing the igniter is a straightforward DIY repair on most Viking models.
- 2
Burned-Out Bake Element (Electric and Dual-Fuel Models)
The bake element runs along the bottom of the oven cavity and draws roughly 2,000–2,500 watts. Over time, the coil can develop a break — sometimes visible as a blister, burn mark, or visible gap in the coil. A healthy Viking bake element reads 18–25Ω; a broken element reads OL (open circuit) on a multimeter.
- 3
Failed Broil Element
The broil element is the upper coil in the oven ceiling. Viking broil elements should read 10–15Ω. A burned-out broil element is often visible (charring, hole in the coil) but must be confirmed with a multimeter test. On dual-fuel models, broil failure doesn't affect gas burner operation.
- 4
Failed Temperature Probe (RTD) — Fault Codes F1 or F3
Viking uses an RTD (resistance temperature detector) probe to monitor oven temperature. The spec is approximately 1,080–1,100Ω at room temperature (Viking part 007891). A shorted probe reads near 0Ω and triggers fault code F1 (temperature runaway). An open probe reads OL and triggers F3 (open RTD). Either condition prevents the oven from heating safely. The probe is typically located at the top rear interior wall.
- 5
Relay Board Failure — One Function Works, Other Does Not
Viking ovens use a relay board to switch power to the bake and broil elements independently. If broil heats but bake does not (or vice versa), a relay is stuck open on the board. This is a board replacement — not a component repair. Discharge any capacitors on the board before handling. Fault code F6 (communication error) can also indicate relay board failure.
- 6
Failed Convection Motor
Convection models circulate hot air with a rear-mounted fan motor. If the fan motor fails, the oven may heat poorly or not at all (on convection-only settings). Test the motor windings — healthy Viking convection motors read 50–150Ω. An OL reading means the winding is open.

Quick DIY Checks
Gas shutoff required: before removing any panel on a gas range, close the gas shutoff valve located behind the unit at the wall connection. Never work on a gas appliance with gas supply active.
Capacitor discharge warning: relay boards and some control boards contain capacitors that hold a dangerous charge even after unplugging. Always discharge capacitors using a 10kΩ resistor before touching board components.
Always unplug the oven from the wall outlet and wait 2 minutes before accessing internal components. Dual-fuel ranges run on 240V — both legs must be de-energized.
- 1Safety first: for gas models, locate the gas shutoff valve behind or below the range and know how to close it before beginning any internal work. Unplug the range from the wall outlet.
- 2Note any fault codes on the display. F1 = temperature runaway (RTD shorted), F3 = open RTD probe, F6 = communication/relay board error. Record the code before clearing it so you can reference the diagnosis.
- 3Gas igniter amperage test: set your multimeter to AC amps (10A range) and clip it around one igniter lead wire. Set the oven to Bake and watch the reading. Healthy igniters draw 3.2–3.6A and the burner lights within 60–90 seconds. A reading below 3.0A with a glowing-but-not-lighting igniter confirms the igniter is weak — replace it.

Repair vs Replace
Viking ranges are built to last 15–20 years and are designed for component-level repair. Most no-heat failures are single-part fixes that cost well under $200. Given the high replacement cost, repair is strongly recommended for ranges under 12 years old in otherwise good condition.
Est. Repair Cost
$30–$200 depending on part (igniter ~$40–$80, element ~$50–$120, RTD probe ~$50–$90, relay board ~$120–$200)
Est. Replacement Cost
$3,000–$8,000+ for a comparable Viking range

Frequently Asked Questions
- Why does my Viking gas oven igniter glow but the burner never lights?
- A glowing igniter that never lights the burner is the classic symptom of a weak igniter. The igniter must draw 3.2–3.6 amps to generate enough heat to open the gas safety valve. When the igniter degrades, it draws less current — enough to glow visibly orange but not enough to trigger the valve. If the igniter glows for more than 2 minutes without the burner lighting, replace the igniter. This accounts for approximately 55% of Viking gas oven no-heat service calls.
- What do fault codes F1, F3, and F6 mean on a Viking oven?
- F1 indicates temperature runaway — the RTD probe is reading an abnormally high temperature, often caused by a shorted probe (near-zero Ω). F3 indicates an open RTD probe — the probe circuit is broken (OL reading on multimeter). Both F1 and F3 are resolved by testing and replacing the RTD probe (Viking part 007891). F6 is a communication error between the control board and relay board — usually indicates relay board failure, though wiring harness damage should be checked first.
- What is the resistance spec for Viking bake and broil elements?
- Viking bake elements should read 18–25Ω when tested with a multimeter (oven unplugged, element leads disconnected). Viking broil elements should read 10–15Ω. Any reading of OL (open circuit) means the element is broken and must be replaced. Visual inspection often reveals a visible gap, blister, or burn mark on a failed element, but resistance testing is the definitive check.
- How does a Viking dual-fuel range work, and how does it affect oven diagnosis?
- Viking dual-fuel ranges combine gas surface burners with an electric oven. This means the gas ignition path (igniter, gas valve) is completely separate from the electric oven path (bake element, broil element, relay board). If the gas burners light normally but the oven doesn't heat, the problem is in the electric oven circuit — elements, RTD probe, or relay board. The dual-fuel design also means the range requires a 240V electrical connection in addition to the gas line.
