it works

I have Rain Bird ESP 8TM Model that has been in service for 8 years. it started to display PR off after thunderstorm. the first time it ever happened. voltage meter reading on wires on transformer was ok. fuse looked ok. I unplugged transformer, fuse, lithium battery, and then put all of them back. The power came back on.

It worked!

Thanks for the information. I had the PR OFF showing after a thunderstorm. Followed your advice and it's working again. Most appreciated!

Pulling the lithium battery and unplugging the unit to reset worked for me too. Thanks guys.

tried it

Notice the PR OFF this morning. Followed the following steps:

1. tried another outlet/checked that original outlet worked - all fine, PR OFF
2. switched fuses (though original looked fine) - PR OFF
3. shut off power to house for one minute - PR OFF
4. stewed - PR OFF
5. found this thread - PR OFF
6. removed lithium battery and fuse - PR OFF
7. put fuse back in - back to normal
8. put battery back in - still back to normal
9. much happier

Great thread all, thanks

Thank you

I had the same problem with the PR OFF error. I googled the problem and thankfully found this site. Even though the original post was from 2006, everything mentioned pertained to my problem today. I replaced the battery, fuses and it still didn't work. I read further and someone mentioned replacing the transformer (plug) and it immediately started to work. Once again, thank you for everyone's input

This helped me too, thanks a *ton*. By the way it's near the top of Google results for the 'PR OFF' error code on this line of models, so given their popularity w/builders it's probably helped a lot more people than us.

I'm not so sure the problem is your transformer. There's could be a problem with the wiring that's causing an intermittent problem. Could be a solenoid going bad.
You need to run it manually a few times and see if the same numbered valve causes the problem.

If you still think you need a new transformer you may as well just buy a new 4 station controller. They're cheap enough.

I've read all these threads, but the bottom line is that my transformer does not supply a steady power supply. It works fine for days, then flips to PR OFF. When I plug the transformer into another plug it instantly works fine for a couple more days. I've got to believe it's the transformer and I can't find a four wire replacement for the Rainbird ESP-4TM. There's plenty of transformers for other models, but not the Model 2650650 4 wire unit.

Have you verified the plug actually works and that the GFI or breaker isn't flipped?
