Troubleshooting Common Commercial Fryer Problems: Tips from Tech24

If you run a restaurant or any food service establishment that uses commercial fryers, you know how important it is to keep your equipment running smoothly. Fryers are the backbone of many kitchens, producing delicious fried foods in a matter of minutes. But what happens when something goes wrong with your fryer? Do you know how to troubleshoot the problem? If you’re ready to learn more about fryer maintenance and troubleshooting, let’s get started! 

Average Lifespan of a Commercial Fryer

The lifespan of a commercial fryer can vary greatly depending on various factors such as maintenance, usage, build material, and manufacturer. Generally, a well-maintained fryer can last up to 15-20 years, while heavy-duty fryers may last 7-10 years. “Gas fryers are typically more durable than electric fryers due to their higher heat output,” says Dillan Taylor of United Service Technology, a Tech24 company. “This actually reduces the energy output by cycling less often to keep the oil at temperature.”  

Yet without proper maintenance, commercial fryers can experience wear-and-tear related issues much earlier than expected. 

Common Causes of Fryer Malfunction 

Proper installation and maintenance are crucial for ensuring the smooth and efficient functioning of a fryer. Improper installation, such as an incorrect utility connection of the gas line or improper voltage, can lead to significant problems down the line. “We also see some instances where bad maintenance results in clogged or worn filtration pumps, as well as malfunctioning thermostats” says Taylor.  “Even using the wrong type of oil – like one that is less heat tolerant, can cause some issues.”  

Frequent overloading of the fryer can also contribute to wear and tear on its components, reducing its lifespan and increasing the likelihood of breakdowns. Furthermore, using the wrong type of oil, which may be less heat tolerant than necessary, can negatively impact the fryer’s functionality and even pose safety risks. Finally, water coming into contact with electrical components can lead to corrosion, compromising the fryer’s electrical system. To ensure the longevity and optimal performance of a fryer, it is essential to prioritize proper installation, regular maintenance, and adherence to recommended usage guidelines. 

Best Practices for Maintaining and Troubleshooting Gas Fryers 

Taylor suggests that following these best practices can help prevent issues and prolong the lifespan of your fryer: 

  • Ensure the gas line has no leaks. Using a soapy water mixture to inspect for bubbles. 
  • Regularly check and clean fryer burners. 
  • Inspect the fryer’s heat exchanger for blockages or damage. Ensuring nothing is blocking the gas flue exhaust.  
  • Check the thermocouple for proper connection and calibration. 
  • Clean the fryer’s oil filter regularly. 


Best Practices for Maintaining and Troubleshooting Electric Fryers 

Electric fryers require different maintenance than gas fryers. Should troubles occur, Taylor suggests these troubleshooting steps:  

  • Check for loose wires and connections and make sure they are properly tightened. 
  • Lubricate the fryer parts regularly to prevent damage due to friction. 
  • Check the temperature regularly to ensure the fryer is operating within recommended guidelines. 
  • Clean the filter regularly to ensure optimal performance. 
  • Check for any debris or residue that could be causing a malfunction.
