Responded to no-heat call on a 2020 Goodman gas furnace. Diagnosed control board failure as evidenced by erratic display showing nonsense characters and periodic blank screen. Board was non-responsive to thermostat calls and direct jumper testing despite proper voltage supply. Removed defective control board and installed new replacement board, restoring normal heating operation.
Re-set existing American standard toilet, with new closet flange.( Existing closet flange set to far below finish floor causing leaking).
