No heat, need help
 

I have an RPJ heat exchanger, it's a comfort maker. The burners will not light, when I switch to manual the blower will not come on. When switching to A/C, the a/c will not come on. There is a loose wire by the blower motor junction box. Also checked the breakers, checked door switch, turned off pilot light and reset it.

Take a picture of the loose wire/inside of the furnace and post it. Does the board have an led light that's on?
