Arrived on site to replace blower motor and 2 limit switches. We started on the upstairs unit, we verified power was turned off and started to disassemble the unit to get to the blower motor. We had to remove the venting, inducer motor, and control boards to get to it. Removed blower wheel and got the motor out. Installed new motor making sure it was the same depth as the old one. Wired everything up and reassembled unit. Replaced limit switch. Since we had to cut the venting to get it out, we installed a coupling. Fired up unit and checked for CO leaks. No leaks present. Furnace is now operating properly. We then went to the other unit and replaced the limit switch with the new one. That system is also operating properly. Thank you for your business!
