Why does my deep fryer keep going out?

Answered by Vince Keith

There could be several reasons why your deep fryer keeps going out, but the most common issues are flameouts and clogged burner ports. Let's dive into each of these problems and explore their causes.

1. Flameouts: Flameouts occur when the flame from the burner is extinguished, usually due to a loss of gas flow. There are a few reasons why this may happen:

– Gas supply: Check if there is an adequate supply of gas to the fryer. Ensure that the gas valve is fully open and that the gas line is not kinked or damaged. Also, make sure that the gas tank or supply is not empty.

– Pilot light: The pilot light may be faulty or not properly ignited. If the pilot light is not generating enough heat, it can cause the main burner flame to go out. Clean the pilot light orifice and ensure that it is properly lit. If needed, consult the manufacturer's instructions for relighting the pilot light.

– Thermocouple malfunction: The thermocouple is a safety device that detects whether the pilot light is lit. If the thermocouple is faulty or dirty, it may not detect the presence of the pilot light, causing the main burner to shut off. Clean or replace the thermocouple if necessary.

2. Clogged burner ports: Another common issue is clogged burner ports, which can restrict the flow of gas to the burner. This can happen due to a buildup of debris, grease, or food particles. Here's what you can do to address this problem:

– Cleaning the burner ports: Turn off the fryer and allow it to cool completely. Remove the burners and inspect the ports for any clogs or blockages. Use a brush or a needle to carefully clean out any debris. Be thorough but gentle to avoid damaging the ports.

– Regular maintenance: To prevent clogs, it's essential to perform regular maintenance on your fryer. Clean the burner ports and other components regularly, following the manufacturer's instructions. This will help ensure proper gas flow and prevent flameouts.

In my personal experience as a brewer, I have encountered instances where the burner ports of the fryer got clogged with residue from frying oil. This resulted in uneven flames or flameouts while using the fryer. Regular cleaning and maintenance of the burner ports helped resolve the issue and maintain consistent performance.

To summarize, if your deep fryer keeps going out, it's likely due to either flameouts caused by a loss of gas flow or clogged burner ports restricting gas flow. Check the gas supply, pilot light, and thermocouple for any issues related to gas flow. Additionally, clean the burner ports regularly to prevent clogs and ensure consistent performance.
