This high-limit thermostat is a safety part used in commercial dishwashers to help control and protect against very high temperatures. It is installed in the heating and wash system and works by checking the heat level using an 18-inch copper sensor probe. If the temperature reaches about 290°F, it automatically shuts off or reduces heating to prevent overheating and damage to the machine. It is commonly used in Hobart commercial dishwashers found in restaurants, hotels, and large kitchens where equipment runs many wash cycles every day. Built with insulated wire leads and secure connectors, it fits directly into the control system for stable operation. If the thermostat becomes worn or fails, it can cause overheating or cycle problems, so replacing it helps restore safe temperature control and keeps the dishwasher running properly and efficiently.
