Mine is a ML121rt. Lights just went dead one day. Took it apart and found a spider egg in the switch and the contacts slightly fouled. The switch comes apart easily. Cleaned it and hit the contacts with a point file. Good as new. Tools needed: Torx bit, voltmeter, point file.

It depends on how the manufacturer made it, but probably the first one that doesn't work is burnt out.

If the timer does not rotate, then the clock motor gears have been stripped, or the motor has gotten weak.
With most expensive timers, you can buy and replace the clock motor.
But not with the Malibu power pack.

I tried spraying WD-40 on my timer dial.
And broke the power pack apart looking for ways to disassemble it.
Power packs are one-piece units.
New power packs have electronic clock, so test your circuit with circuit analyzer before assuming new electronic gizmo will work better.

"Harry" wrote in two months ago with a brilliant work-around.
His timer stopped working.
He bought a cheap plug-in timer and then connected power pack to that timer.

Harry also said that his power pack has 5 year warranty.
He was 'negotiating' with over the warranty.
I hope he writes back and says how it went.
Here's the contact page.

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

Another option is to take advantage of fixya phone support.

suggest testing with a volt meter on max voltage setting between A and C or A and B or B and C

as these may be tappings from the secondary coil and depending on where you place wires you might get different voltages .
then pick which ac voltage you require
