Hello, i have intermatic px300 low lighting transformer. I bought this house one year ago.Transformer was installed recently before i bought by the privious owner of the house but pool and landscape lights never turned on. Transformer is connected to hayward pool timer which has pool and spa lighting switches.I can go into hayward timer and turn on light option on the panel and i can hear transformer turning on,can hear huming sound but no lights come on on pool and spa. opened up tranformer but there is no timer dial or light censor. Don't know if it can be turned on manually to see it is working.

If it is keeping time try moving the stops. If it is not keeping time the motor is probably burned out. These transformers don't have a lot of serviceable parts to them.

I discovered that I hadn't turned the manual switch to off on the one that wasn't working properly.
Now they both work fine. The instructions that come with the Malibu Transformer is not easy to understand and it does not go into enough detail. There isn't a trouble shooting section which would help.

Just checking, still plugged in, fuse or circuit breaker not tripped that provides power to it? If you can turn it manually, and the dial does not turn when powered up, look for a small on/off switch, other than that, maybe it does need replacement, but they usually last longer that a year, but I have had some timers that just quit working on me too.
