Common Reasons for Pilot Light to go Out

A pilot light is a small flame that ignites the main burner on a gas heater. When the pilot light goes out, it can be due to several factors. The most common reasons for a pilot light to go out are insufficient gas flow and blockages in the gas line. Insufficient gas flow can occur when there is a leak in the line or when the regulator is not set correctly. Blockages in the line can be caused by dirt and debris buildup or from insects building nests inside of the pipe.

What to do When the Pilot Light Won’t Stay Lit

When troubleshooting a pilot light that won’t stay lit, it’s important to check all of the components involved in order to determine what could be causing the issue. First, check the gas regulator and O-rings for any signs of damage or wear. If they appear to be in good condition, then clean away any insect or dust buildup that may have accumulated inside of the pipe. This will ensure that there is an adequate flow of gas going through the line. Additionally, inspect any valves on the system for any signs of corrosion or leakage.

Natural Gas Vs Propane Tanks

The type of fuel used by Mr Heater MH540T will affect its performance and how often maintenance needs to be done on it. Natural gas tanks tend to have higher BTU ratings than propane tanks, meaning they produce more heat with less fuel consumption. However, natural gas requires a larger storage tank compared to propane tanks, making them slightly more expensive to purchase and install initially. Propane tanks are generally considered more reliable since they don’t need as much maintenance as natural gas tanks since they don’t require as much pressure regulation during use.
