I have a Irritrol Rain Dial RD900-Int about 5 years old, and I noticed this morning that the display was blank. For some reason by particular model does not have a fuse, unless it is hidden somewhere - it's not on the wiring panel. I've checked the valve/solenoid wiring and can't find a problem there. The transformer is a bit warm but I don't think excessively so. Any help troubleshooting the problem would be greatly appreciated.
