✅ AC BOARD REPLACEMENT PART– This AC Board (DLB021-V2) is the replacement component designed specifically for Bambu Lab A1 and A1 Mini 3D printers. It serves as the power distribution circuit board that delivers AC power to the heatbed, ensuring your printer maintains stable bed temperatures for consistent, warp-free print quality.
🔥 RESTORE HEATBED FUNCTIONALITY– If your A1 heatbed fails to heat up, heats inconsistently, or you're encountering heating-related errors, this AC power distribution board is the direct replacement solution. The board manages power delivery to the heatbed and is a critical component for restoring full printing functionality.
⭐ UPDATED V2 DESIGN– This V2 version features an updated design for improved reliability and thermal management. The new revision has been optimized while maintaining full compatibility with A1 printers. IMPORTANT: If your original board has a yellow ground wire, simply reconnect it to the same terminal on the new board.
🔧 EASY DIY INSTALLATION– Designed for straightforward user-serviceable replacement. Full step-by-step installation guide is available on the official Bambu Lab Wiki. Basic tools required (H1.5 & H2.0 hex keys). Always disconnect the printer from power before beginning any replacement procedure.
⚠️ CRITICAL COMPATIBILITY NOTICE– This AC Board is ONLY compatible with Bambu Lab A1 printers. THIS BOARD DOES NOT FIT A2L – Please verify your printer model before purchasing. A1 Series uses part number SPC002 / DLB021-V2. If you own an A2L printer, this board is NOT the correct replacement part.
