What should you check if a gas appliance fails to ignite?

When a gas appliance fails to ignite, it is essential to check both the power supply and the gas supply. The power supply is critical because many gas appliances rely on electrical components to initiate the ignition process. A disruption in the power supply could prevent igniters from working correctly.

Simultaneously, the gas supply must be verified to ensure that gas is flowing to the appliance. If there is an interruption in the gas line, issues such as closed valves, leaks, or obstructions can prevent the gas from reaching the appliance, making ignition impossible. Ensuring that both supplies are functioning allows you to rule out two of the most common causes of ignition failure, leading to a more efficient troubleshooting process.

Other options, while potentially relevant in broader contexts, do not directly address the immediate problem of ignition failure. The warranty status is not a direct factor in the appliance's operational state, the brand does not influence ignition issues specifically, and the location may be relevant in terms of installation but does not typically affect whether the appliance will ignite or not.
