Orizizhic Digital Thermostat Controller Board for Pit Boss PB700 PB820 PB440 PB340 – HD LCD, Smoke & High-Heat Modes

Orizizhic's digital thermostat controller board replaces the original Pit Boss control board to restore reliable temperature control and the W/LCD display to your PB700, PB820, PB440 or PB340 wood pellet grill.

When a failing control board leaves a pellet grill unstable or unresponsive, swapping in a compatible replacement is often the fastest path back to consistent heat and predictable cooking. This Orizizhic vertical digital control board is built to match the electrical and display connections used across multiple Pit Boss models, offering an HD LCD readout, eight preset temperature ranges and a dedicated smoke mode so you can switch between low-and-slow and high-heat cooking without juggling external controllers.

Which Pit Boss models will this replacement board work with?

This board is designed to fit a range of Pit Boss wood pellet grills and smokers that use the same vertical digital controller format. It matches mounting, connectors and the display style found on several PB series models, making it a common swap for owners troubleshooting control failures.

• Compatible models: PB820SC, PB820FBC, PB820D, PB820FB
• Also fits: PB700SC, PB700S, PB700D, PB700FB
• Additional compatibility: PB440D and PB340

How does the controller help me manage smoking and grilling?

The Orizizhic board includes an adjustable "P" or program setting and multiple temperature steps so you can select either a prolonged low-heat smoke or quick high-heat cooking. The LCD screen provides clear temperature readouts so you can monitor progress without guessing.

• Smoke mode: low-temperature setting for longer smoke durations
• High-heat mode: ramps up for faster searing and shorter cook times
• 8 temperature options from 200°F to 475°F for flexible cooking profiles

What display and material features should I expect?

The unit uses a high-definition LCD to present grill temperature and status information in an easy-to-read format. The control board assembly is built from PBCA material for durability and long service life in typical outdoor cooking conditions.

• HD LCD: clear, easy-to-read temperature and mode indicators
• Durable PBCA construction for reliable, long-term use
• Black finish matches the original equipment look

Are there installation notes or measurements I should check before ordering?

Measure the existing board and verify connector types before purchase to ensure fitment; small tolerances in color and measurement are possible. If you need guidance during installation, contact customer support for assistance rather than forcing incompatible parts together.

• Confirm the vertical board layout and connector positions on your grill
• Allow for a 1–2 mm variance in manual measurements when comparing parts
• Color displayed on screens may differ slightly between batches
