    • Hi Tim,
      Unfortunately, that’s a typical symptom of a failing controller. I’ll email you with repair details shortly.

  2. Hello. I have an old Hardie rain dial controller. It just says Hardie near the bottom right but does not have a model number on the left, it is blank (I think it may be an RD-600). I currently have two issues. First, the + – buttons on the top right stopped working. For a while I would have to push them 3-4 times to get them to work but now when I push them, nothing happens. The other issue is the numbers in the hour column on the clock/timer are starting to fade/disappear. For example, the number 8 only shows part of the number and a couple other number are just blank. Can these issues be fixed/repaired or am I better off buying a new controller? Thanks.

    • Hi Mike,

      Yes, those issues can usually be fixed. If not, I have some replacement options available. I’d suggest you send it in for repair and we’ll go from there. Just send it in – For details, see the page on how to get it repaired.

      • Hi Brian,

        Thanks for the response. Will you just need me to send the controller or will you also need the connector board?

        Thanks,

        Mike

        • From the description of the problem, you don’t need to send the back terminal board. If you’re willing to take on the extra hassle, there’s no reason not to; I can inspect and test it. It’s up to you.

          Thanks,
