Transformer purchased to correct power issue to main unit

After having a power fault appear on my controller unit the repair fix was to replace the power transformer. I purchased the transformer expecting it to fix the fault but it didn’t. So now I have to purchase a complete unit after only three years not to mention the $35 I just spent to replace the transformer. Any other thoughts on the fault would be appreciated.

Hi Michael, thank you for reaching out. We're sorry to hear the transformer did not fix the issue as expected. Please reach out to our customer service team at to discuss the situation further. Thank you, your Holman Team.

Worked well

I purchased this to replace a transformer for a Toro watering controller. Asit was same voltage and power rating it worked great.

The transformer for my Holman Dial Ezy irrigation controller physically broke so needed to be replaced.
I ordered a replacement unit from Holman and the part arrived promptly and worked a treat.
Many thanks.

I was surprised at the speed that mu transformers arrived 3 days from order to delivery considering all the delays caused by this virus, I only purchased two to keep one as a spare as have four controlers working for over ten years and this is the first fault I have had , very pleased with controlers and the service.
If you ever modify these controllers could you please make the screens a bit larger as I like many people my age with failing vision find them hard to read and set up especially the am and pm settings
Thanks Lennard Solly
