Coleman furnace model # 7956A856 ,

The problem I'm experiencing is that the burners will not ignite. It was working fine this morning came home from work to a cold house. The pilot is still lit,. has current, the thermostat is functioning, as is the limit switch as there is continuity from the one terminal to the other the only thing I can think of is the small transformer died,. no burner and no fan turn on to provide heat.

Any sugestions??
Thanks for any support anyone can give,.
