If the left burner in a furnace is misaligned, what could it cause?

When a furnace's left burner is misaligned, it can lead to fluctuating heat output. This misalignment may disrupt the combustion process, causing uneven burning of the gas or fuel. As a result, the temperature produced by that burner can vary, leading to inconsistent heating. Homeowners might notice cold spots or areas in their living spaces that do not reach the desired temperature while others may become too hot, making the overall heating system function inefficiently.

Moreover, fluctuating heat output can also affect the thermostat's ability to maintain a consistent temperature, leading to increased cycling of the furnace as it struggles to keep up with the heating demands of the home. This not only diminishes comfort but can also place additional strain on the furnace, potentially leading to further mechanical issues over time.
