Malibu landscape transformer

The timer won't work. I can manually turn on/off lights. Are there simple checks I need to do before replacing the tranformer?

    The unit does not keep time. I can only turn it on and off manually. Brand new - it never worked. I am taking it back to the store. Originally, I thought I simply could not locate the timer on/off switch.

    I have two different Malibu timers that will not switch the lights on. If I remove the pegs, the timer works fine. However, whent he on/off pegs are installed, the timer stops at teh peg and will notturn the unit on.

    I have a ML88T that has this problem. I've removed the timer face and found that the gear linking the motor gear to the timer gear is worn enough as to no longer engage with the motor gear.



    Too bad I have not found this gear to be available. As long as the motor is not burned out, this little gear would solve the problem.

    While wiggling my light bulb to see if it would come on, all the lights in the malibu system went out. Power appears to be going to tranformer

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.

We have a Malibu 300 low wattage transformer for 13- 20 watt landscape lights.


Try connecting a lamp (correct voltage, etc) directly to the transformer. Most likely, the wire from the transformer to your lights is broken... The reset button can't reset anything, if there's nothing wrong there.

We have an outside landscape light time that has quit working. Model pb115m1. Do you carry these?


Fixya does not sell timers or parts.

Timer system is not identified for certain.
If landscape system still turns on-off with override switch, then you can work around and buy cheap plug-in timer, set landscape to override, and plug landscape system into cheap timer.

Open following link for low voltage transformer resources:

I bought a Malibu 300W low voltage landscape transformer to replace a 200W unit that stopped working. It worked for 1 week, then stopped .. the reset **** doen't work. The LED works, I do see a...


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.

Need the on/off (red/black) pins to set on/off times on a 9yr. old Malibu landscape lighting transformer. Simple, where I may procure these pins? This is not a trick question.


Yours is a frequently asked question... twice today
I don't see Malibu tripper pins anywhere on the internet or at Malibulights.com

The newest Power packs are digital and don't have tripper pins.

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.

Malibu TDC PTST-30012 turns on in the middle of the day


1) Contact malibu lights directly.
Their site does not acknowledge TDC PTST-30012, so I cannot access a manual with best information.
Their products come with a warranty.
http://malibulights.com/customer_service/contact_us.aspx
http://malibulights.com/customer_service/owners_manuals.aspx

2) If unit can be set to override, you can buy cheap photo eye timer, and then plug power pack into cheap timer, but there is no guarantee this will work, or that power pack will burn out.
http://www.amazon.com/Intermatic-HB61RC-Digital-Outdoor-Control/dp/B00004W4X5

3) Buy ordinary power pack with dial-type timer, and then buy photo eye that fits.

http://store.nexternal.com/intermatic/categories.aspx?Keyword=ML814DRP&x=15&y=10

4) As electrician, I would not buy anything that costs more than $15 that comes with built-in photo eye that cannot be replaced.
Especially something as buggy as a low voltage power pack.

Malibu landscape lighting transformer problem


Testing ohms across A and B will read open circuit through transformer coil.
Testing DC voltage across terminals A and B should read 12 volts DC, and nothing less.
Transformer should make humming sound when working.
Test that receptacle has power and breaker is not tripped.

There are no repair parts for power packs, but they come with 5 year limited warranty.

Malibu landscape transformer


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.
