Have a clients furnace that isn't working correctly, stated that the furnace doesn't turn on. Due to heat element that I ohmed out and no continuity. But she stated that now the fan (blower motor) doesn't work. Troubleshooted and motor works, bypassed control board and motor turns on. The trouble is when I jump C to G, the condenser turns on and not the blower motor. Did the test connector to C and the led light does rapid flash. I'm thinking the board is shot. Any advice? I'm new to the field and trying to get some experience by doing some side work. I am "qualified" have EPA cerification and went through the proper training but like life. Experience isn't learned in books.
