    Need a 24vac 1250ma transformer, where can I find one? My timer displays fine w/batt
    I have the RD 900 int. The display stopped working. I put in an alkaline 9v and the display shows fine. I'm suspecting the transformer is bad. It's a model #a5724125-1, part # 872901. 24vac@1250MA. Please advise of your thoughts and/or parts info. Bob ***REMOVED NAME AND PHONE NUMBER*** (TKR)

    What is "RD 900 int."

    Also, posting a phone number on a message board like this is not the best idea.

    We know it's a timer of some sort.

    24 V @ 1.25A or bigger is an easy find. If the mfr is no help, then DigiKey Corp. | Electronic Components Distributor | United States Home Page

    , Mouser Electronics - Electronic Component Distributor

    Or

    US - Electronic Components Distributor | Newark.com are possibilities for new parts.


    Might be best to try surplus.

    I would not "suspect" the transformer, that's discrimination, I would Test before replacing.
