Annual Inspection Guide for Your Dual Fuel Range and Oven (9 Steps)

If the kitchen is the heart of the home, then the range and oven are its lifeblood. A well-designed kitchen range and oven will last you many years, and maintenance tends to be minimal for quality models. However, setting a reminder for an annual DIY inspection is key to safe, effective cooking.

In this guide, we'll cover everything you need to know about how to inspect your dual fuel kitchen range and oven, from the 9 simple inspection steps to handling any issues you spot.

Why Dual Fuel Ranges Require Their Own Guide

If you own a dual fuel range, you've found the right inspection guide—because a dual fuel range isn't just a gas range and an electric oven mashed together. The two systems interact with each other, so you shouldn't just combine the steps found in an inspection guide for gas ranges and an inspection guide for electric ovens separately.

In quick non-technical terms, a dual fuel range has two different heating sources. That means the heat from the electric oven may affect nearby gas lines or igniters. Dual fuel ranges also have unique ventilation needs because poor ventilation can trap both heat and combustion gases.

Those are just a few of the reasons why dual fuel ranges need their own annual inspection guide, which you've found here!

9 Steps for Inspecting Your Dual Fuel

 Range and Oven

The following steps will reduce risks and increase the lifespan of your unit. If you own a Hauslane dual fuel range (or if you're thinking about purchasing one), know that each unit comes with a 5-year parts and labor warranty in case you find any issues.

Step 1: Prepare Your Dual Fuel Range for Inspection

As we mentioned above, you've got two power sources to take care of with a dual fuel range—electric for the oven and gas for the range. Both need to be powered off.

That means you'll need to:

• Turn off the power at the breaker
• Shut off the gas valve
• Ensure the unit is completely cool
• Gather gloves and a flashlight

Step 2: Review the Unit's Exterior Structure

Review the unit for any cracks in the oven glass, and make sure it's standing solidly on the ground (no tilt due to an uneven foundation). Cracks can make your oven less efficient, and both those cracks and any unevenness may present safety hazards.

Next, review the following:

• Control knobs for the gas range and electronic panels for the oven
• Oven glass integrity
• Door alignment and closure
• General stability of the unit (dual fuel units tend to be heavier than others)
• Any signs of rust or corrosion at the base

Step 3: Check the Integrity of the Gasket

The gasket is the name for the seal that goes around the edge of the oven door, keeping the heat inside. If you've noticed signs of inefficient sealing, such as longer preheat times or uneven baking, pay particular attention to the gasket.

Inspect the gasket for:

• Smooth opening and closing
• Any cracks in the gasket
• Signs of heat leakage around the outside of the door

Step 4: Inspect the Oven's Interior

Avoid excess grease buildup within the oven, since that can create safety hazards and affect cooking quality. Additionally, look for any excess wear on the oven itself and any electrical components.

Check the interior of the unit for:

• Baked-on grease
• Enamel that is flaking or falling off
• Racks that are warped
• Malfunctioning oven light
• Fan-assisted convection components (if applicable)

One thing to note is that if you see smoke during preheating, that's often caused by excess grease buildup, as opposed to electrical issues.

Step 5: Ventilation & Range Hood Check

We've written a complete guide for inspecting range hoods, but for this job, you'll want to perform a cursory check for:

• Efficient airflow
• Clean filters (i.e., make sure there's no grease buildup)

If you need to clean or replace your filters, take a look at our guide for filter cleaning and replacement. Charcoal filters are designed to be replaced, while baffle, mesh, and hybrid filters are designed for cleaning and continuous use.

Step 6: Electrical Systems Check

It's important to note that you should not attempt to perform any electrical work on your own unless you're a qualified electrician. What you'll do here is a quick visual inspection to spot any frayed cords or loose plugs in the electrical system that heats the oven.

If you spot any issues, call a professional. Trying to repair these issues on your own simply isn't safe, so it's just not worth it.

Step 7: Gas Connections Check

Now it's time to review the gas connections that fuel the burners on the range. Just like with the electrical components, this is just a visual inspection. If you spot any issues, call a professional.

Inspect the gas system for:

• Gas line kinks or corrosion
• Connections that are loose
• Any signs of gas leaks

Gas smells like rotten eggs, which comes from sulfur that gas companies add to natural gas. On its own, natural gas is odorless. They add sulfur so you'll notice the smell immediately and call for help, since gas leaks can be deadly.

Step 8: Inspect the Heating Elements (Gas Burners + Electrical Oven)

Now it's time to turn the gas valve back on and reconnect the electricity so you can test the heating elements of both the gas burners and the electric oven.

For the gas-powered range, inspect the following:

• Burner ports to ensure they're not clogged with grease or food
• Clicking igniters to ensure they light properly
• Flame color to ensure it's blue and steady (and not yellow or uneven)

For the electric oven, look for even heat distribution, and consult your manual if any error codes show up.

Step 9: Performance Test

Run the following tests, one at a time, on both the gas range and the electric oven.

• Boil water on each gas burner
• Preheat the oven and verify temperature accuracy
• Check for any unusual noises (fans, igniters, relays, etc.)
