The bundle includes the digital W\/LCD control board, a meat probe, an RTD temperature sensor, a high‑temperature igniter hot rod with stainless sleeve, and a protective fuse. It’s designed to match the functionality of OEM boards while adding improved short‑circuit protection and consistent temperature holding.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this kit restore temperature control on my Pit Boss grill?\u003c\/h3\u003e\n\u003cp\u003eThe replacement controller supports 10 cooking temperature settings from 180°F to 500°F and lets you fine‑tune in 25°F or 50°F steps. It also retains a dedicated smoke mode with eight pellet feed profiles (P0–P7) for slow smoking. Together, the controller and RTD grill sensor deliver faster, more accurate feedback so the controller can maintain steadier heat.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e10 preset cooking ranges: 180°F–500°F with 25\/50°F adjustments\u003c\/li\u003e\n  \u003cli\u003eSmoke mode with 8 pellet feed options (P0–P7)\u003c\/li\u003e\n  \u003cli\u003eRTD sensor provides quicker, more precise grill temp readings\u003c\/li\u003e\n  \u003cli\u003eLCD\/W digital readout for clear status and settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat safety or durability improvements does this replacement offer?\u003c\/h3\u003e\n\u003cp\u003eThis upgraded board adds protections against short circuits that can burn out controllers or trip GFCIs.
