Furnace wont start automaticly

Hello everyone

I have a Inter-City CGC-75 furnace for the basement in my house. When I bought the house the I wasnt told the basment furnace didnt work. Upon inspection of the furnace I noticed that the motor was seized, So I replaced the motor thinking this was the only fix. Nope it isnt. When the thermostat calls for heat nothing happens at the furnce. If i push the white button in on what I think is the fan limit switch or turn the external fan switch to ON the burnner kicks in and the basment get warm. I only problem is the fan doesnt shut off till I shut the switch off. I have replaced the fan limiter but that is all so far.

Thanks alot for any and all help.

Good chance the black wire above the white button belongs where the red wire is, and the red where that black wire is.

The white button is a fan on button.
