What symptom might indicate a problem with the pressure regulator?

A symptom that might indicate a problem with the pressure regulator is when the pilot burner goes out when the main burner attempts to ignite. This situation typically arises because the pressure regulator is not maintaining the correct pressure of gas required for the appliance’s operation. The pressure regulator is responsible for ensuring that the gas pressure remains within the specifications necessary for proper combustion. If the pressure is too low, the pilot may not stay lit when there is an increased demand for gas, such as when the main burner turns on.

In contrast, when equipment operates efficiently or the appliances get too hot, it often suggests that the system is functioning correctly or perhaps has an issue related to something other than the pressure regulator. Irregular ignition of burners could also point to a problem, yet it may involve other factors such as the air-to-gas mixture or the condition of the burners themselves, rather than solely a malfunction of the pressure regulator. Thus, the significance of the pilot burner going out during high-demand situations highlights a direct correlation to the performance of the pressure regulator within the gas system.
