Viking Oven Not Heating? Here Is What Is Wrong and What It Costs to Fix

A Viking oven that will not heat — or that heats inconsistently — is a frustrating problem in a kitchen built around professional performance. The good news is that Viking oven heating failures are almost always repairable, and the repair cost is a fraction of what a new Viking range costs.

This guide covers every common cause of Viking oven heating failure, organized by oven type.

Viking gas ovens use a glow bar igniter to open the gas safety valve. This is the most common point of failure.

When you set the oven to bake, the igniter begins to glow. As it heats up, it draws increasing electrical current. When the current reaches a threshold (typically 3.2–3.6 amps), the gas safety valve opens and gas flows to the burner. The hot igniter then ignites the gas.

If the igniter is weak — drawing less than the required current — the safety valve never opens and the oven never lights.

• The igniter glows orange but the oven does not light after 90 seconds
• The oven takes 15–20 minutes to preheat (weak igniter is barely opening the valve)
• The oven lights, heats for a while, then shuts off (igniter weakens as it heats up)
• The igniter does not glow at all

Repair cost: $200–$375 for igniter replacement. This is the most common Viking oven repair.

If the igniter tests at correct amperage but the oven still does not light, the gas safety valve itself has failed.

Repair cost: $275–$475.

The oven temperature sensor (also called the RTD probe) monitors oven temperature and signals the control board to cycle the burner on and off. A failed sensor causes the oven to overheat, underheat, or not heat at all.

Signs: Oven temperature is significantly off from the set temperature. Error codes F3 or F4 on the display.

Repair cost: $150–$275.

The electronic control board manages all oven functions. A failed board can prevent heating entirely or cause erratic behavior.

Signs: Error codes on the display, unresponsive controls, or the oven behaves unpredictably.

Repair cost: $300–$575.

Viking's dual fuel ranges use an electric oven with a gas cooktop. The electric oven uses a bake element (bottom) and broil element (top) rather than a gas igniter system.

The bake element is the most common failure point in Viking dual fuel ovens. It is the heating element at the bottom of the oven cavity.

Signs: The oven does not heat when set to Bake. The broil function may still work. You may see a visible break, burn mark, or blister on the element.

Repair cost: $150–$275.

The broil element is at the top of the oven cavity. When it fails, the broil function does not work but baking may be unaffected.

Repair cost: $150–$275.

Some Viking dual fuel models have a hidden bake element beneath the oven floor. These are less accessible but the repair process is similar.

Repair cost: $175–$325.

Same as gas models — the RTD probe monitors oven temperature. Failure causes temperature inaccuracy or no heating.

Repair cost: $150–$275.

Before assuming a component failure, check whether your Viking oven simply needs calibration. Viking ovens allow temperature offset adjustment through the control panel. If your oven is consistently 25–50°F off but otherwise heats normally, calibration may resolve the issue without a service call.

Consult your Viking owner's manual for calibration instructions. If the oven is more than 50°F off or the temperature varies widely, a sensor or control board issue is more likely.

We carry Viking igniters, elements, sensors, and common control boards on our service trucks. Most Viking oven repairs are completed in a single visit.
