Upon arrival I cut square openout of return duct. Then I pressure washed coil with shop vac connected to drainline. Theni removed panels and pressure washed the other side. Homeowner said last night it froze up and stopped working. After cleaning coil,pan and drainline I started system. The blower would not start. The cabinet bottom was wet from ice melting and control board lays on the floor. It got wet and blower would not start. I had to wire around board with relay to by pass board. It is now cooling until install hopefully.
