I urgently need a specific part for a pool heater, particularly the pcb/control board. I've provided the part number before, and I'm reaching out again as it's critical for my repairs. Could you please let me know the availability and pricing for this component? It's been a few emails now, and your prompt response would greatly help me move forward. Thank you for your assistance!
