The Newco 100174 High Limit 36FMH04 is a temperature safety control used in compatible commercial coffee brewing equipment. It monitors operating temperatures and interrupts the electrical circuit when a preset temperature threshold is reached, helping prevent overheating conditions. This disc-type high-limit control is rated for 222°F and is commonly used in select Newco coffee machine applications. The compact assembly integrates into the equipment control system and functions as part of the thermal protection circuit. Replacing a faulty high-limit control restores proper temperature safety monitoring and equipment operation.
