MARS CAMP Replacement Control Board Kit for Pit Boss (PB700/340/440/820) — LCD Thermostat with Meat Probe & Ignitor

This upgraded MARS CAMP replacement parts kit refreshes Pit Boss digital thermostat controllers and includes a temperature control board, meat probe sensor, ignitor hot rod, and a meat probe. It is built to be compatible with popular Pit Boss models (PB700, 340, 440, 820) and replaces worn or faulty components to restore reliable temperature control and ignition. The kit’s LCD display and selectable modes (Smoke and High) give more control over cook settings from 200 to 475°F, while the added meat-probe interface brings optional internal-probe monitoring to your grill setup.

How does this kit improve temperature control and readability?

The upgraded control board includes a high-definition LCD that reports the grill temperature clearly and supports two operating modes—Smoke and High—so you can shift between low-and-slow and higher-heat cooking. The board also adds a dedicated meat probe input with temperature switching, letting the controller respond to probe readings when you want to monitor internal meat temperature.

• LCD display shows current grill temperature precisely.
• Smoke and High modes cover low-temp smoking to searing ranges (200–475°F).
• Meat probe interface allows automatic switching to probe-based control.
• Drop-in replacement for compatible Pit Boss digital controllers.

What parts are included and do they fit my Pit Boss model?

The package contains the upgraded thermostat/control board, an ignitor hot rod, a temperature probe sensor (meat probe), and necessary connectors. It’s designed to fit Pit Boss pellet grills PB700, 340, 440, and 820; verify model compatibility against your existing harness and mounting before installation.

• Control board with LCD and probe port included.
• Ignitor hot rod for reliable pellet ignition.
• Meat probe sensor for internal temperature monitoring.
• Compatible with PB700, 340, 440, 820—check connector shapes and screw locations.

How difficult is installation and what tools do I need?

Installation is intended to be straightforward for someone comfortable with small appliance repairs. Typical steps involve disconnecting power, removing the old panel, swapping the control board and wiring plugs, and mounting the new ignitor; no advanced soldering is usually required.

• Turn off and unplug the grill before starting installation.
• Basic hand tools (screwdrivers, pliers) are typically sufficient.
• Follow connector alignment and secure mounting screws to avoid vibration issues.
• If unsure, consult a technician or follow model-specific service guides.

What performance differences should I expect versus the factory part?

This MARS CAMP kit adds a meat-probe switching function that many stock kits lack, plus a clearer LCD and the ability to operate in defined Smoke or High modes. Expect more consistent ignition from the included hot rod and the convenience of probe-driven temperature management during longer cooks.

• Probe-driven control reduces guesswork for roast doneness.
• Improved LCD readability aids monitoring at a glance.
• New ignitor reduces startup failures common with worn rods.
• Tested at the factory for basic operational quality before shipping.

Who is this for: the MARS CAMP upgrade kit is for Pit Boss owners who need to replace failing electronic parts or who want an enhanced control board with meat-probe capability. It’s best suited to DIY-savvy grillers who own compatible Pit Boss PB700, 340, 440, or 820 models and want clearer temperature feedback, dependable ignition, and the option to control the grill by internal meat temperature during longer cooks.
