Gas Grill Repair

Let’s barbecue tonight! This Fix-It Guide on gas grill repair tells how a gas grill works, what often goes wrong, how to identify a gas grill problem, and what parts and tools you will need to fix it. It then gives simple step-by-step instructions for how to test a gas grill propane tank valve for leaks and how to test gas grill hose fittings for leaks.

How Does a Gas Grill Work?

A gas grill is an outdoor cooking appliance, fueled by propane or natural gas, for grilling or barbecuing a variety of foods outdoors. A controlled amount of gas passes from the metal tank or household gas lines through fittings and a hose to the burners, where the gas is slowly consumed, creating heat for cooking on the grill top. Gas grills have become more popular than charcoal grills thanks to their ease of use.

What Can Go Wrong with a Gas Grill?

Because they are simple in operation, it’s relatively easy to determine what’s wrong with a problematic gas grill. Gas can leak from fittings or from the hose itself. The igniter may not spark.


Always transport a propane gas tank upright with the valve completely closed and the safety plug screwed in tightly.

How Can I Identify a Gas Grill Problem?

At the beginning of each barbecue season and after filling and reattaching the propane tank, you should test the unit for gas leaks. Follow instructions below and/or purchase a gas leak check kit at a hardware store or propane tank supplier.

What Do I Need for Gas Grill Repair?

 Gas Grill Repair

Replacement parts for gas grills are available through larger hardware stores.

Worn parts such as cooking grates, flavor bars, burners, and more are easily available and easily installed. Because most working components within gas grills are made by a small number of manufacturers, many parts are interchangeable and readily available. First check the gas grill department of a larger home improvement center or hardware store. If you don’t find the part you need, contact the grill’s manufacturer or an aftermarket supplier.

To disassemble and repair your gas grill, you’ll need the following tools and materials:

  • Wrenches
  • Small paint brush
  • Soapy water

What Are the Steps to Gas Grill Repair?

Test a gas grill propane tank valve for leaks:

  1. Turn the grill control knobs on the front (and, on some models, the side) of the barbecue to the off position.
  2. Turn the propane tank valve fully counterclockwise to close it.
  3. Mix a test solution of equal parts of dishwashing liquid and water in a small container.
  4. To test for leaks, apply the test solution liberally to the connection between the regulator fitting and the tank valve using a small paint brush. Apply the test solution to the valve handle and threads, the length of the hose, and the connection between the hose and the regulator. If bubbles appear at any point, there is a gas leak.
  5. Tighten the connections and retest.
  6. If you still see bubbles at any of the tested connections, close the tank valve and replace the leaking component.

Test gas grill hose fittings for leaks:

  1. With the tank valve open, brush the test solution on the fitting at the other end of the hose, located under the control knobs.
  2. Turn the control knob to high and test the hose and fittings leading from the control knob to the grill. Turn the right control knob to off. Repeat the process for the other control knobs.
  3. If you see any bubbles during any of these tests, close the tank valve and contact your propane dealer or your local gas utility. Do not use the barbecue until the leak is corrected.

Fix-It Tip

If your grill uses a home gas line, periodically inspect the connections for corrosion. If you find a problem, contact your gas supplier for repairs.
