What’s the difference between different RainDial Models.

Irritrol RainDial contrrollers are sometimes referred to as the RD600; the RD900 and RD1200 are the same as the RD600 except that they have more stations. (RD900 has 9 stations, and the RD1200 has 12 stations, the max number of sprinkler valves supported by the Irritrol Rain Dial series of timers.)

The RD600-R, RD900-R and the RD1200-R timers are newer versions of the non “-R” models and are the more blue units show in the header of this page.  The repair process is slightly different and they are generally not compatible with the older more-gray label RD600, RD900 and RD1200 controllers. We repair all of them frequently and would appreciate your business.

Send an email with the model number and problem description by using the Contact Us Link; we usually respond the same day and your email is kept private.

Common RainDial problems we solve:

  • Buzzing, chattering, or non-working valves
  • Erratic or flashing displays
  • It turns off immediately after you turn it on.
  • Intermittent watering behavior
  • Shorter than expected battery life

What we do – The RainDial Repair Process steps:

  1. Many of units are mailed to or dropped off at our location in North Phoenix/Glendale and picked up the next day
  2. Repair time is typically 1-2 days, same day with prior arrangements.
  3. The replacement parts have better ratings than in the original
  4. The work and parts replaced are guaranteed for 12 months+
  5. You’ll only pay if we can fix it.
  6. We have years of experience in the electronics and computer industry.
  7. In some cases, the backboard is needed for repair depending on the symptoms, contact us for more information.

What we do not do:

  1. We are not a landscaping or sprinkler/sprinkler system installation company; we only do electronic repair
  2. Repairing your equipment is usually the best option and is what we prefer to do so you don’t have to worry about compatibility issues or inheriting someone else’s problem.  We repair circuitry in your existing timer and return it.
  3. LCD screens are generally not repairable or replaceable unless we have used equipment that we can take them from.
  4. We are not affiliated in any way with the Irritrol Rain Dial company.

Considering a used or other replacement timer?  Repairing RainDials make more sense:

  • The Rain Dial timers are great, they’re easy to program and use and the screen is big enough to see easily.
  • Removing the controller for repair and re-installing afterwards only takes a few minutes and can be done by anyone at any skill level.
  • Older rain dial timers will likely have the same failing parts found in the one your’re replacing.
  • Filling the landfills with timers that could be repaired just doesn’t make sense.

Helpful Irritrol Rain Dial Troubleshooting Tips and instructions:

We’re firm believers in do-it-yourself – and we don’t want you to send us something to repair when it’s not broken.  See the RainDial troubleshooting tab for lots of do it yourself diagnostics and troubleshooting.

  1. Brian, Thanks for the reply regarding the M and the number on the display.
    I went out and checked out of the wiring, making sure they were connected, changed the battery and did the ribbon check. Still no luck; any other suggestions?
    Appreciate the assistance.
