I have called them and they just tell me they have no parts without looking. They suppose to have the Parts Inventory but they don't have the parts I need. I have contacted the company and asked for the numbers of the fan and motor suppliers. The ID Fan Unit in these heaters are weak prone to break. The heat warps the fan and bends the motor shaft as it is soft steel and not tempersd. I can put new shaft on the motor if I have to get some tempered 5/16 rod and cut to length and push on the armature and the bearings and install the end caps.
