Nahntaipy Digital Thermostat Control Board for Pit Boss PB340 PB440 PB700 PB820 – LCD Display, 9-Setting Temp Controller

Nahntaipy's upgraded digital thermostat control board replaces the factory controller on compatible Pit Boss pellet grills to restore precise temperature control and the LCD readout.

This drop-in replacement control panel and circuit board assembly is built for Pit Boss models PB340, PB440, PB700 series and PB820 series. It combines a clear LCD, nine cooking temperature settings (including a high-temp option) and a smoke mode so your pellet grill reaches and maintains the temperature you select. The printed circuit board uses high-density PBCA material for durability and the kit includes color-coded wiring to simplify installation.
