  If your Maxx Ice Maker isn't producing ice, several factors could be at play. First, ensure the icemaker is installed correctly, referring to the user manual for guidance. Inspect the cooling system's pipes, particularly the welding points, for any signs of oil leakage, which indicates a potential gas leak. Also, examine the water system for leaks, paying close attention to connections. Lastly, consider whether the water filter requires replacement and if the ice maker needs cleaning.
