If an LP-Gas appliance does not ignite, what is the first step to troubleshoot?

The first step to troubleshoot an LP-Gas appliance that does not ignite is to turn off the appliance and investigate if gas is flowing. This action is critical because it allows the technician or the user to determine whether the issue is related to gas supply. If the appliance is not receiving gas, it cannot ignite, and further steps would be unnecessary without ensuring that gas is present.

By first checking the gas flow, one can identify any potential blockages in the gas line or check if the gas supply valve is open. Additionally, confirming that gas is available can help isolate the problem more effectively and inform subsequent troubleshooting steps.

Calling a technician for assistance should come after initial checks have been made, as professionals are typically called when basic troubleshooting does not resolve the issue. Looking for visible damage to the appliance is also necessary but can be done after confirming gas flow to ensure that the subsequent steps are taken in an informed sequence. Trying to ignite it again repeatedly is not advisable because it may lead to a buildup of gas, increasing the risk of an explosion or fire, particularly if there is a gas leak.
