Hi Brian, thank you for reaching out. Unfortunately, there is no direct replacement available for the Mircom FX-350-60-DR. This model has unique features and specifications, and as of my knowledge cutoff in September 2021, Mircom hadn’t released a direct successor. If you’re experiencing issues with your current panel, I’d recommend contacting Mircom’s customer support for guidance on potential solutions or considering a system upgrade to a newer model if your application permits. Always ensure local codes and regulations are followed during any replacement or upgrade process.
