Your cart is empty. This is a replacement AUTOMATIC thermal cut off switch for the Grainfather G30 OR T500 Boiler. This is the most common point of failure for most electric boilers. When the switch is blown your unit won't heat. The Grainfather G30v3 auto reset switch avoids the need to manually reset the system to ensure homebrewers can easily resume their brew day if an unexpected reset is required. The switch is made to sense temperature and cut off power at around 125C (257f) when the boiler is almost empty. This NEW MODEL switch will reset itself automatically and works on the original T500. You don't need to push the reset button underneath the T500 any more. Just let it cool and the switch will reset itself.
From Hobby Homebrew: There may also be a fuse to check continuity on. It looks like a thick place on the wire.
