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.

SOURCE: Lights will turn on and off manually only

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.

We have an older Malibu 300w low voltage transformer that has a non-working timer and want to install a photo eye on it. The instructions for the photo eye as well as recent IFU from Malibu show 3...


How about this solution:
Don't use the photo eye from Intermatic, since unsure if older timers might not be made for that feature.
Instead, plug power pack into photo-eye timer.
Or plug power pack into ordinary wall timer:

I have model ml600twsn 600 watt intermatic timer for my outdoor lights.Recently I have been unable to set them to turn off an on automatically. I can manually. what should I do?


You have malibu-type low-voltage transformer.

There are no repair parts for this type of timer, and nobody reports being able to fix timer once it goes bad.

1) "Harry" wrote to fixya with a work-around: He bought cheap plug-in timer, set malibu timer on override, and plugged malibu into wall timer.

2) Harry also said that his timer has 5 year warranty, and he was negotiating for replacement.
Contact Intermatic:
http://www.intermatic.com/customer%20service.aspx

3) Buy another timer:
http://www.amazon.com/Malibu-Intermatic-600watt-Professional-Transformer/dp/B000PGPO50

4) I found tips for next power pack that might save money:
The reason I add tips now, before power pack needs replacement is some fella wrote fixya.
He bought 500 Watt power pack to replace 300 Watt > thinking bigger was better.
Power pack burned out. Here's why:
a) Match wattage of bulbs with wattage of power pack
-15 each X 20 watt bulbs = 300 watts, so install 300Watt power pack
b) Installing a 500W power pack on 300W of bulbs will burn out bulbs and power pack.
c) Replace bulbs as soon as they burn out or other bulbs will burn out and power pack will burn out.
d) When working on bulbs, unplug power pack or it may burn out.

One year outdoor lighting (300V #135708) Transformer not working


You need to disconnect the lighting load completely from the transformer and check it's output. If it is dead unloaded, replace the transformer. If it seems to work now, then some part of the lighting circuit has probably shorted out. If there are several circuits coming to the transformer, attach each one separately and recheck for power. When one is attached that kills the output, investigate that circuit. Check for any broken lamps first, then the wiring must be opened at each lamp location to check for a local short circuit. A somewhat tedious fix. Hope this helps!

Malibu 600 watt transformer timer not working. Can turn on and off w/ the switch but the timer isn't functioning.


The timer motor is probably bad. Unfortunately, Malibu transformers have very few user servicable parts :-( , and the timer motor isn't one of them. One cannot even access the internal connections. If you recently purchased the transformer, return it to the store. If the transformer is less than 5 years old, it's still under warranty. In that case visit the Malibu website for instuctions.

Power at 3 feet, not at 2 feet ???


You might need to check the power source for proper voltage, sometimes outdoor wiring is at the mercy of the elements. Rusty screws on recepticles and so forth. Another problem could be exposed wire in the line bleeding of to ground. Sometimes this happens if a fixture is removed and the wire not properly protected. If these are none of your problems just take up your fixtures and replace the wire. 16 guage underground feed will probably be less expensive than the transformer you bought.
