Returned to a recall and found that the drain pan was full of water. Upon further diagnosis we found that the condensate drain line was clogged and not pitched correctly. This allowed water to back flows in to the secondary pan and over flow outside of the pan. We cut out the old drain line and installed a condensate pump with a new line and ran it to the outside of the house. We prime and tested the drain pump to make sure it was draining freely and it is currently draining properly. The system is working according to specifications.
