In order to see the red part of the temperature controller as blue, two new blue LEDs had to be replaced with transparent ones. I tried reinstalling the original transparent lightbulbs but it didn't help. The original bulbs were then replaced with new clear LED bulbs which, like the new blue LEDs, had to meet the correct voltage tolerance. Even then, the technologist had to replace one of the resistors on the board to make it work. Now the unit, although new, looks even better than my original.
