Frymaster 8100427 Fryer Thermocouple 1/4" 180°

A flame-sensing temperature part used in commercial gas fryers, this thermocouple helps check the pilot flame and makes a small electrical signal (20–30 MV) to support safe gas control operation. It has a 48-inch coaxial design with 1/4-inch tubing and an 11/32"-32 threaded connection, so it can be installed safely in matching fryer systems. The 180-degree flame pattern design helps it correctly sense heat from the pilot flame and send the right signal to the fryer’s control system. This part is commonly installed in commercial kitchens such as restaurants, hotels, and foodservice places where heavy fryers are used all day. It is used in machines that need accurate flame checking to stay safe and cook food at the right temperature. If a thermocouple becomes weak or stops working, the fryer may not light or may not heat properly. Replacing it helps bring back correct flame sensing, improves safety, and keeps the fryer working smoothly.

Equipment Compatibility:
Typical uses for the Frymaster Thermocouple include commercial gas fryer systems used in busy kitchen environments. This Thermocouple 8100427 works with equipment from brands like Frymaster, Dean, Garland, and similar fryer systems, where accurate flame sensing and steady burner control are needed for safe operation.

Brand Compatibility:
This thermocouple replaces several Frymaster, Dean, Garland, and more part numbers used in fryer equipment. Full cross-reference details are provided separately for easy identification.
