Hello Team, I do have KD6 unit and its been working very good. But today I didn’t see any display (its a blank). And then I unplugged the power supply and put it back, but still not working. I also checked my fuse which tied to garage and sprinkler controller. So, I am seeking help to see what can be done to restore it. Thanks
Hi Ramana,
Can you check to see if you have 24VAC? You can get a multimeter from harbor freight for around $8 to check. Also check here https://raindialdoctor.com/sprinklers-dont-come-on-when-they-should/ and look at item C
Brief power outage caused reset even though I have battery backup. All days were set to ‘one’. Bad battery or something else?
PS I’ve diagnosed a bad solenoid using your troubleshooting guide. Thanks for that.
PPS You repaired my timer almost 2 years ago and it’s still going strong!
Hi Gary, I thought I replied earlier, but I don’t see it now.
Yes, it should maintain your programming through a power outage as the battery is good. You might check the battery and then test this by turning the power off to the timer. The display should still show the time in the program should be maintained. If it doesn’t, let me know and we’ll figure out what to do. Perhaps the battery connections have failed or something like that.
Let me know what you find out. I’m glad your time has been working so well for you after all these years. Regards, Brian.

Today setting is showing SU and it will not change days when push + or -.
What is way to change
Double check that you have the bottom center switch in the middle position which says set programs.
That should allow you to change the day of the week by pressing the + and -.
You might try moving the switch back-and-forth a few times and make sure that it’s seated in the middle properly.
Let me know how it goes

First, my RD600-EXT-R has been malfunctioning for a few months, going off program and watering for long stretches outside the program. Sometimes the unit displayed the wrong time. A few days ago, I tested the backup battery and found it was bad and replaced it. The unit reprogramed ok. But this morning when I checked the unit (we are expecting unusual rain) the display was blank. I followed the instructions for resetting the older models, once and the instructions for the newer models twice. The display is still blank although it may be lit.
As an additional complication, I ran over the fuse with my car, The glass is gone but the fuse still fits in the brackets and the filament is intact. Let me know if I need to replace the fuse before I can proceed. Pictures are available
Hi Richard, I also got your email and we’ve kind of closed out this conversation that way. If you have any other issues, just let me know.
I’m glad We were able to get it all repaired and working like new again.
