This replacement kit is designed for Pit Boss pellet grills and includes a digital control board, RTD temperature probe and hot rod igniter so your grill can regain accurate temperature regulation and dependable starts. It fits a wide range of Pit Boss models (PB340, PB440D, PB700 series and PB820 series), offering a plug-and-play approach for DIY repairs without requiring advanced electrical experience.

Which Pit Boss grills does this FlameEngine kit work with?

The kit is compatible with a broad list of Pit Boss models commonly used by backyard cooks and prosumers. Check your existing control board model and connector types to confirm fit before ordering.

• Compatible models: PB340, PB440D, PB700FB, PB700D, PB700S, PB700SC, PB820FB, PB820D, PB820FBC, PB820SC
• Includes matching connectors for original wiring harnesses on these models
• Designed to replace the original digital control board, RTD probe and hot rod igniter

How does this kit improve temperature accuracy and smoke control?

The new digital board uses a precision RTD probe and an updated control algorithm to deliver stable temperature readings across the typical grill range. That stability helps reduce temperature swings so food cooks more predictably and smoke settings perform consistently.

• Temperature range supported approximately 170°F to 475°F for common grilling and smoking
• RTD probe provides more consistent sensor readings than basic thermistors
• 9-position temperature knob with a dedicated smoker setting for controlled smoke output

What’s included and how easy is installation?

The package arrives as a ready-to-install replacement set with components designed for plug-and-play assembly. Installation typically involves unplugging the old board and parts, swapping in the new components, and testing ignition and temperature control.

• Kit contents: digital control board, RTD temperature probe, hot rod igniter and mounting hardware as needed
• Plug-and-play connections match original harnesses — no soldering required in most cases
• Basic mechanical skills and common tools (screwdriver, pliers) are usually sufficient

Will this kit restore reliable ignition and long-term performance?

The hot rod igniter included is sized to replace worn or failed igniters, and the board is inspected before shipping to ensure functional components. Proper installation and keeping pellets dry will help maintain reliable starts and consistent temperature control.

• Hot rod igniter designed to replace failed factory igniters for dependable starts
• Factory inspection procedures applied before shipment to reduce DOA risk
• Regular maintenance (cleaning auger, ash and hopper) improves longevity
