Repair – RD600, RD600-R

Select this option to have your existing Rain Dial controller repaired. Simply mail it to us, or drop it off.  We'll repair it and send it back. Details are below. (Continental US Only).

Secure payments are made using PayPal which also accepts all major credit cards; and your contact information is kept private. If you send a check with the unit, make it out to "Brian Keller."

  1. Repair time: Typically 2 days.
  2. What's needed for repair:
    1. The controller unit without the battery - just 30 seconds to remove, see this link for details
    2. Back-connector board (not the case with the transformer, just the board).   Sometimes this isn't necessary - but we always recommend sending it. If you're not comfortable removing it, let me know.  With a few more questions we can determine how critical it is to send. If you have a "mostly blue label" controller, or models with -R at the end, it is required.  
      • Just loosen the screws holding the wires, slide them out, then remove 4 "Philips" screws that hold it  into the case.
      • Do not send the entire case (it's too much work), just the yellow or white connector board with all the screw terminals.

  1. Hi

    I have a Raindial RD600-EXT. I have solenoids are chattering and making the pipes bang inside the walls. Valves work fine manually. Based in your trouble shooting this seems to be the control module. Do you repair or sell refurbished

    • Hi Mike,

      I prefer to refurbish your original model to avoid any compatibility issues, and you don’t get any latent defects from someone else…

      I’ll followup with an email separately that includes all the details.
      Thanks for posting,

  2. Hi,
    Our RD-600 has a flashing LCD, it will hold the time but the irrigation doesn’t start either with the timer set or on a manual basis. Is this something you can repair?

    • Hi Susan,

      If your timer still shows an LCD display when the battery is removed, you know the transformer is good and it can be repaired. Send in the timer, the back connector/terminal board is probably not needed.


  3. Howdy, I have a RD-600-INT manufactured Jan 31 2000. The black plastic rotary selector switch broke off. Do you have a new one? Can I replace it? Thanks.

    • Hi Rod,

      If you’re a do-it-yourself guy, you can contact Irritrol and they’ll send you a replacement dial. If you’d like us to do it, just send it in and we’ll do the dial and replace the other parts that typically fail. This would ensure it lasts for a long, long time.

      I’ll include this in response to your email as well.


  4. Hi I have a RD-600 Unit that recently is having intermittent problems that perhaps you can advise.

    After three(3) weeks or so, the 9v battery requires replacement. This is the second time this has happened so I gather a more pressing failure is evident in my system.

    Can you advise based on your experience what the problem may be.

    • Hi Steven,

      That’s a common symptom of a timer failure that I repair. I’d look at the menu that describes how to get it repaired. Just send it in and we’ll get it back to you. We’re not too busy now so we turn them around “next day”. If you need to, you can manually water by using the manual feature of the valve itself instead of the timer.

      Let me know what you think,
