AC03P9 PB1100PS1 Control Board for Pit Boss - LCD Thermostat Panel

Our review of the AC03P9 PB1100PS1 control board finds it is a practical replacement part for owners who need to restore precise temperature control to select Pit Boss wood pellet grills and smokers. The single biggest reason to buy is straightforward: it restores the grill's original LCD thermostat interface and eight cooking settings, making it ideal for cooks who want a simple plug-in swap rather than a full controller upgrade. Installation is basic wiring to match four color-coded leads, and the board returns the familiar temperature and smoke modes most backyard smokers expect.

Key Features

• Compatibility: Fits a range of Pit Boss models so owners of PB1100PS1, PB820, PB550 Navigator and similar units can use the same replacement board.
• LCD display: Restores the original digital readout so temperature and mode information is easy to read while cooking.
• Eight temperature settings: Offers eight cooking presets from 200F to 475F plus a smoke mode to cover low-and-slow to high-heat grilling.
• Simple replacement: Connect the four wires by matching colors and you can have the panel working without advanced tools or soldering.
• No probe included: Keeps the board focused on controller functions but requires a separate meat probe if you need internal temperature monitoring.

Who It's For

This control board is best for Pit Boss owners whose OEM panel has failed or become unreliable and who want a like-for-like replacement that restores the LCD thermostat interface and preset temperature range. It appeals to DIYers comfortable matching four color-coded wires inside the grill to replace the controller quickly.

It is not suitable for owners of vertical smokers or anyone needing built-in Wi-Fi or advanced probe features, since the unit does not include a meat probe and lacks wireless connectivity. If remote control or smart features are required, shoppers should look at a different upgrade path.
