usually overheating is a bad sensor. Generally a heater coated with calcium lacks heat. The problem is one of 2 items:
One is the temp sensor is defective.
Two is the control board the sensor reports to is bad.
Does the heater run nonstop or does it actually turn off finally but at a higher temp?
Do we know for sure what thermister was replaced? Part number or description?
Due to site rules you would have to contact them. I apologize.

I really wish you the best.
