Commercial appliances are an essential part of any business that relies on them, from restaurants and hotels to hospitals and laundromats. If you've ever had an appliance break down during a crucial time, such as right before dinner hour in a busy restaurant, you already know that unexpected malfunctions can have a significant impact on your bottom line. Although commercial appliances are built to withstand heavy usage, over time they can break down, meaning that parts may need to be replaced.

Following are five common commercial appliance replacement parts and when it's time to replace them.


The compressor is the heart of a commercial refrigerator or freezer. It pumps refrigerant through the system, and if it fails, the appliance won't cool properly. Signs that your compressor may need to be replaced include loud noises, a noticeable decrease in cooling efficiency, and leaks around the compressor.

Heating Element

Heating elements are used in commercial appliances such as ovens, fryers, and dishwashers. Over time, these elements can become worn or damaged, leading to uneven heating or complete failure. Signs that a heating element needs to be replaced include cold spots in an oven, slow heating, or a complete lack of heat.


Commercial gas appliances, such as ovens and ranges, use igniters to start the flame. If the igniter fails, the appliance won't light, and food won't cook properly. Signs that an igniter needs to be replaced include a lack of heat, a weak flame, or no flame at all.


Belts are used in many commercial appliances, such as washing machines and dryers. Over time, belts can become worn or damaged, leading to poor performance or complete failure. Signs that a belt needs to be replaced include excessive noise, vibration, or slippage.

Control Board

The control board is the brain of a commercial appliance, controlling functions such as temperature and timing. If the control board fails, the appliance may not function at all or may function improperly. Signs that a control board needs to be replaced include error messages, flashing lights, or unresponsive controls.

When to Replace Parts

Knowing when to replace commercial appliance replacement parts is crucial to preventing breakdowns and maintaining efficiency. Signs of wear and tear or damage should be addressed promptly to prevent more significant problems from developing. A general rule of thumb is to replace parts every half decade or so, depending on usage and the type of appliance.
