Banbitebq Digital Thermostat Control Board for Pit Boss P7 Series — Matte Black Trapezoid with RTD Probe & Upgraded Circuit

The Banbitebq Trapezoid Upgraded Digital Thermostat Control Board (AC03P7) is a direct replacement controller for select Pit Boss P7-series and Austin XL pellet grills, complete with RTD temperature probe and four OEM temperature-control programs.

Designed to fit several Pit Boss models (including P7-340, P7-540, P7-700, Austin XL P7-1000, and PB440FB1 Matte Black), this replacement board restores temperature regulation, pellet feeding options, and built-in cook profiles. It arrives as a matte-black trapezoid module with an RTD probe and an upgraded circuit meant to tolerate ignitor short circuits better than the original controller.

How does this control board restore my grill’s temperature control?

The AC03P7 uses an RTD temperature probe and digital thermostat logic to read grill temps and command the auger, fan, and ignitor. Its firmware includes four OEM profiles tuned to different Pit Boss models, ensuring stable temperature maintenance across the 200°F–500°F cooking range.

• RTD probe for accurate temperature sensing
• Digital thermostat logic to modulate fan and auger
• Four model-specific temperature programs (codes S01, P01, L02, L03)
• 200°F–500°F cooking range for versatile recipes

What safety and durability upgrades are included?

The board features an upgraded circuit layout that reduces the risk of damage when the ignitor rod shorts. In many instances, this design helps the fuse remain intact and prevents the controller from burning out, improving the unit’s longevity and reducing replacement frequency.

• Reinforced circuitry to handle ignitor short events
• Design aimed at preserving the fuse during faults
• Matte-black housing for corrosion resistance and discreet styling

Which Pit Boss models and functions are supported by this replacement?

This control board is compatible with specific Pit Boss grills and includes software presets that match those models. Verify your grill model before ordering because the board is not compatible with Onyx Edition units.

• Compatible models: Tailgater (PB340TGW1), Lexington 500 (PB500LXW1), Classic (PB700FBW2), Austin XL (PB1000XLW1), Matte Black (PB440FB1)

• Program codes: S01 (440FB1/Tailgater), P01 (Lexington), L02 (Classic), L03 (Austin XL)

How does this controller expand my cooking options?

The AC03P7 offers eight pellet feed settings, allowing you to tailor smoke intensity and heat recovery. It supports a full suite of cooking methods—smoking, baking, braising, roasting, grilling, barbecuing, char-grilling, and searing—using one controller and variable pellet delivery.

• Eight pellet feed rates for fine smoke and heat control
• Prime Boost function to quickly add pellets for faster reheating or richer smoke
• Enables low-and-slow smoking or high-temperature searing in one unit

Who is this for: Grill owners with compatible Pit Boss P7-series or Austin XL grills who need a reliable replacement controller that restores factory-style temperature control and expands durability. It’s suited to DIY installers comfortable verifying model numbers and swapping electronic components; professional technicians will also appreciate the improved circuit protection for busy repair shops.
