December 3rd, 2025 I returned to install the control board and blower motor. I tested both system after installation and they are both fully functional and heating. I proposed adding surge protection to all units. I emailed the videos, pictures, and invoice. The left downstairs system’s control board is burnt up and not passing voltage. The right down stairs system is having a blower motor issue. When in a call for heat the blower motor does not engage resulting in the high temperature limit switch to become tripped.
