Waterfurnace geothermal diagnostic System locked out on condensate safety Cleared drain and put Condensate drain treatment tablets in the coil drain pan Reusable filter that was being used is not sized properly. As a result, edges of the coil were dirty, which contributed to the drain clogging Sprayed no-rinse coil cleaner on the air coil All of these issues would be prevented with a regular maintenance. Our plan includes a correct 28x30x2 filter on each visit We also make sure the drain is clear System is operating normally at this time
