      Brittany BaldwinAug 17, 2025
      This flashing pattern suggests several potential issues: a vent blockage or improper configuration, kinked or blocked pressure switch tubing, a faulty pressure switch, the vent termination being affected by wind, the blower not spinning up to speed, the blower or exhaust temperature being too high, or a faulty blower temperature switch. Check the vent or vent tables.
