Hi, my name is XXXXX XXXXX I will assist you with your question.
From what you are describing and the fact that the fan is not kicking on this issue is consistent with a failed coolant temperature sensor,this is a common failure.

Hi Mike it is a brand new thermostat /housing and coolant temp sender combined .Could it be a blocked heater matrix

Yes it is very possible that the heater matrix is restricted and causing the problem.
