I have a Trane YCC042 Gas heating and the ignitor wouldn't work so I found
the problem to be the thermal fuse was bad. This unit is about 11 years
old and hasn't given any past problems. Does anyone know what the usual
problem is for this unit to blow the thermal fuse ? I know that excessive
heat blows it and it's a safety fuse but what might be the actual cause ??
I didn't see any holes or rust in the burner area.

What did the Trane technician tell you?
