🔧Work Performed
Customer described issues is a heater failure for the DAD. Upon arriving on site, HPLC stack was turned off. After
turning all the modules on, including the DAD lamps, I did not see the heater error that the customer saw. I began
pumping water through the stack, but I was never able to reproduce the heater failure. Verified previous failures by
checking the error history. If the heater fails, it is recommended to replace both the fan and heater assemblies.
Replaced the DAD fan and heater assemblies. After parts replacement, allowed stack to pump with water while the
detector warmed up for 30 minutes, which allows the heater controller to work with optimized parameters. There
was no heater failure afterward. Closing call.
