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?

RE: It worked!

Thanks for posting this. Just unplugged after trying everything else and it worked. Saved me a bunch of time and money.

Same for me, I took out the fuse, took out the battery, unplugged the 'wall wart adapter.' Waited 15 seconds. I put the battery back, I put the fuse back, plugged the wall adapter back in, and viola! back to normal.
