Reasons Why a Wolf Oven Won’t Heat Up

It’s a major inconvenience when your oven refuses to heat up. Several factors like not turning off the Showroom mode, incomplete preheating, component malfunction, and more, cause the problem. 

Here are the most common reasons why a Wolf oven won’t heat up.

Showroom Mode Is On

When the oven is in Showroom mode, the lighting, and display work as if it's in operation. The temperatures might even reflect on the display. 

However, the oven isn’t fully functional and doesn’t heat up. 

Methods to turn off Showroom mode varies per model. If you think you activated it by accident, check out the manufacturer’s guide to turn it off.

Incomplete Preheating

Always preheat your oven before use. Preheating ensures that heat is evenly distributed inside the oven. 

This is an essential step in food preparation as it guarantees that your food is completely cooked from the inside. 

Before you put food into your oven, allow it to reach the desired temperature first. The preheating indicator light goes off once preheating is complete.

Preheat times vary per voltage requirement, size, and model. You need to preheat 208-volt models longer than the 240-volt models.

The preheating process often takes longer for large and propane-fueled ovens. 

In addition, be sure to fix any cracks or damage in your oven’s door or gasket seal as they affect preheating time. Note that preheating isn’t applicable for Broil and Convection Broil modes. 

Problems With Gas or Power Supply 

Check to see if the gas oven is loaded with the required pressure and supply. 

Always check for leaks and immediately turn off the gas valve from your main supply line when it happens. Do not attempt to repair leaks on your own. 

Contact repair services as soon as possible. Gas leaks are dangerous and may result in kitchen fire if not treated promptly. 

For Wolf electric ovens, properly connect them to a compatible power supply source. Use a multimeter to check if your outlet’s voltage is sufficient.

Electric ovens usually require 240 volts and gas models require 120 volts.

Malfunctioning Oven Components

In some cases, faulty oven components are causing the problem. 

  1. Defective Heating Element

Your oven’s heating element is the metal coil that illuminates in bright orange or red color when on. It’s responsible for converting electrical energy into heat.

The presence of cracks, blisters, burns, or any visible damage indicates that you need to replace your heating element. 

Notice the illumination of your heating element. Over time, the glow starts to dim and is no longer bright orange or red. This means that heating capacity is compromised and may result in undercooked food. 

Don’t forget to check for loose connections or worn-out wires that may contribute to the problem.

In addition, a damaged heating element consumes more electricity so it can compensate for its inability to convert heat. As a result, your electricity bill spikes up. 

  1. Control Panel Malfunction

Control panel switches control oven features, temperatures, timers, and modes. 

An error message appears on the display if the control panel isn’t physically damaged. When this happens, turn the oven off and wait for 30-60 seconds before turning it on again. 

In some cases, sudden energy surges or regular wear and tear cause damage to the relays of the entire control panel.

Contact repair services to have your control board replaced.

  1. Convection Fan Not Working

Convection fans are in charge of circulating heat within the oven to hasten cooking. At the same time, it's also responsible for cooling the oven afterward. 

Heat won’t distribute evenly if your fan it's broken. If this is the case, parts of the convection fan may be obstructed or there may be problems with the fan’s motor. 

  1. Faulty Igniter

Using electricity, the igniter opens the safety valve to allow gas to flow. It produces a spark to light the gas as it flows through. 

The easiest way to tell if there’s damage in your igniter is to observe if it fails to ignite your burners after 1 minute and 30 seconds. 

You may also use a multimeter to check for damages in the igniter. 


There are four common reasons why your oven does not heat: the Showroom mode is on, incomplete preheating, gas or power supply problems, and malfunction in oven components.

Check the components of your oven for any visible signs of deterioration, changes in illumination or color, and blockage. 

Call a qualified repair expert to fix the issues, especially for gas leaks.
