how can I fix my Zanussi Condenser Dryer TC 470 ?

My ZANUSSI condenser dryer stopped rotating and left a burning smell . I opened it up and managed to free the drum from the resistance against rotation.I took the belt off to check the motor running under no load and motor runnig ok. I suspect that it was overloaded with clothes and came off the drum guides. I also think that this caused the heater to burn out when there was no fan ventilation over the heater.It rotates ok now but there is no heating.Does it have a high limit cut out that can be reset? I have no wiring diagram to assist me in my attempt to restore the heating of the unit. thank you
