SOURCE: burn out circuit board
hi! there! replace the burn out circiut board,what ever you pull out the same thing you put back just be sure that has the same model and specification,calibrate and test overload protection,defective overload protection replaced to prevent any burn out,short circuited mostly came to burn those thing that's why imposing preventive maintenace schedule for this kind of large ac central unit is very much significant.mostly timer delay circuit malfunction on large scale unit supplying by three phase a/c source on central control panel board.when ever replacement occured try to put mark or list color coding of specific terminals to connect and isolate short circuit make possible to detect at once before installing the new one and make make record on this for future reference we have several cases like that after buying a new one and replaced still burn again,the common cases is that they did not find the cause of short circuit connection they just relay on circuit board burn out,so it better to make assured that every thing is fine before installing the new one.specially on supply source of circuit.,relay on diagram and manuals take and check all data source as reference this will be a great help.take all necessary precaution this should be done by qualified technical ac support,have a nice day and regards

you would have to study the wirring diagram etc but any gas heater control should work, you just have to know how to hook it up as the ignition etc is all incorporated in the control
