Motor has gotten weak, and is overheating and soon will not work.
Some people report taking apart motor and cleaning gears.
Others report that they didn't record how the gears came off, and can not reassemble.
PB912M10 Clock module is not sold separately.

Switch power pack to override so lights are ON, and plug transformer into cheap wall timer.

First time I've heard of this problem... and since Intermatic doesn't have exact part, I would guess the problem is not common.
Usually the trippers wear out or timer module stops or transformer burns out after power outage or bulbs burn out and are left unchanged so transformer overheats and quietly stops working.

1) Suggest use gorilla glue and stick the thing back together in that manner.
2) If the wires from transformer are connected to terminals, then you can use the flimsy plastic and glue it into place.
3) Post a photo on internet and send link so expert can see what you have.
4) Of if product is still under the 5-year warranty period, then send back to Intermatic and let them fix the product.

Use an extension cord to plug the transformer into a different "test" GFCI receptacle, if it holds on the test GFCI you know that the GFCI for the transformer needs replaced. If it doesn't hold, then the transformer is on the way out and should be replaced. Sometimes motors and transformers will "leak" current and still work, but not trip a regular circuit breaker. A GFCI that is doing it's job will catch it though. Don't force a GFCI like that...you can wear it out prematurely.

Power pack wattage has to match bulb wattage, or it shortens life of power pack.
I don't know physics and electrical engineering enough to know why this happens.
Also when working on bulbs, manual says to unplug power pack so it doesn't burn up.
If bulb is under water that's fine, but wiring cannot be underwater where it shorts out, or suspect this action might also shorten life of power pack.
With receipt, power pack could still be under warranty.

I don't have repair for defective transformer.
The transformer puts power on the wire. Buy multimeter and check voltage across the terminals.
If wires are loose, or bulbs are not connected to wire, or bulbs burned out, or if wattage of bulbs is mis-matched with transformer wattage, then lights might not work as expected.

I don't know if it burned out, but something is not right.
Malibu products come with 1-5 year warranty.
New product that stopped working should be exchanged for full replacement at place of purchase, except possibly the auction sites.
New Malibu product should work for many years.
Be sure to match bulb voltage with transformer voltage to avoid possible problems.
Mismatched bulb and transformer wattage should not affect a timer in short period such as 1 week.
Another thing to check is outlet polarity. Use circuit analyzer from home center to check outlet.
