I have a Nordyne Central Unit that it won't ligth. This is the first time I turned it on. The only thing I see is a red light blinking on the circuit board. I don't have the manual on this unit so I have no idea what is wrong. Any help with this problem will be appericated.

I found out that is had a ground problem. Found the Manual online looked up the code and it told me I had a power problem. Checked the connections and cleaned them. Turned the power back on an no problem.
