    • Hi Peter,
      Short means that the solenoid has shorted out and is bad, or the wiring is crossed somewhere. It is usually not a timer problem. I would recommend replacing the solenoid for the valve that the timer is trying to turn on and can’t. It is a do it yourself job for about $15 to $20.

  1. Does my Raindial Irritrol Model# RD600 run on a battery? If so, what kind? At present I am not strong enough to open the door on the right.

    • Hi Roberta,
      No, it does not run on a battery. There is a 9 volt battery in the back of the timer on the top that is used to keep the clock running if the power goes out. The battery is not required for it to operate. The panel on the right is not intended to be accessed because it contains high voltage. If you describe what the problem is more, I can offer further assistance.

    • Hi Robert,
      Thanks for the inquiry. That sounds like a problem we typically see. I would recommend sending both the controller and backboard in for repair. If you have a -R model, make sure to send in both parts. I will send you an email with repair information.

    • Hi John,
      I would recommend trying a factory reset. I have instructions on how to do a reset here. Let me know how it goes.

  2. I would like to send you a picture of my controller digital readout it is stuck on -94 and -AM and -HOUR and will not change, we have had power out for 5 days I hav changed the battery and still stays on that readout not sure what to do lawn is getting pretty dry, let me know what you think

  3. We’ve got an RD-900, station 6 is not working.Take it, RD900 only has 9 active stations although there are 12 stations to connect up to, that correct???

    • You’re correct. the backboards typically have screws and wiring for 12 stations, but the timers only implement circuitry to control what it advertises on the label. Thus, you won’t be able to move the wire for #6 to the wire for #10 or above and have it turn on.
      Try swapping wire #6 with #5 and see if 5 quits working. If so, it’s probably the solenoid. If 6 still doesn’t turn anything on then it’s a timer issue.

      I’d suggest sending the back terminal board in for repair with the timer and we’ll get it back good as new.
      Let me know if that answers your question and if you’re willing to send it in or drop it off (If you’re in the Phoenix area)
