Is changing this controller something a lab technician could do in house or would pro-service be required? Also do you offer service for these if we wanted the controller professionally changed?

The controller replacement is fairly simple. To determine which replacement controller you would need, look at the serial number of the HotBlock. If the serial number contains “CEC” then you need SC945. If it contains “CECW” then you need SC945-W. You would just remove the old and put in the new one and wire back color for color. If it is a SC945, you would have to unwire and rewire since the controller will not fit into the cutout with the wires on. I recommend that you take a picture of the wiring before you start so that you have a picture reference also. If you want to send it to us, you would need a decontamination sheet filled out and we would replace the controller and check out the rest of the unit for any other failing items since it is already at our location and taken apart. Once it is ran and tested we would send it back to you.
