Did your Nordson® ProBlue® unit stop heating? It could be the heater. The heater (KNS0045 for 240V and KNS0046 for 480V) is cast in a protective block and the complete assembly can easily be changed with 2 bolts and thermal grease.
The Importance of Thermal Grease
It is very important to apply the thermal grease on the entire surface of the heater manifold. Spotty application can result in failure of the heater.
