I have a
Malibu 8100-9045-01 45 watt 12VAC outdoor transformer



The transformer works except for the photo cell. The transformer has a photo cell test function and it shows bad.The cell is on a 2 wire cord that plugs into the bottom of the transformer. Since it is plug in I assume (maybe in error) that it is replaceable. Have done numerous google searches and am unable to find a replacement.


Any one have any ideas?

What about electronic suppliers ? (components).

The device to which you refer is almost certainly a Light Dependent Resister (LDR). However, there is also the plug connection and mounting involved.

You should, in the first instance, contact the manufacturer concerning a spare part. Since the entire device is available for about $50, the spare part should not cost TOO much - but that is not always the case!

While LDRs can be obtained for a few cents each, there are various types - with different Light/Dark resistance ranges and you will need to obtain an appropriate type to suite the electronics in the "box", should you choose to do a DIY repair.

Also, are you sure that the LDR has "failed". (This would be quite unusual, since such components are not normally "stressed" when in operation).
Is there, perhaps, some problem (open circuit) with the connection to the device or to its plug connection?

You can get one of these and they work fine. Just remove or bypass the current LDR.

Lowe's also carries them.

Not sure why you think that would replace the photo LDR. That unit is a new timer. My existing timer works fine and I can use it with timer settings but I want to get the turn on at dusk feature working again.

 

[herdfan]

Because it is a photocell that turns the unit with multiple Off settings. There even make one that will set an actual OFF time. So on at dusk, off at 1am.

It would not technically replace the LDR, but would replace its functionality.

The items under that number are "Malibu Low Voltage FastLock Twist Connectors 8101-4802-01" - not a PhotoCell.

Old tread revived by a Newbie.
Since its about 9 months, I'm pretty sure RJ has it fixed by now.

Or not!

I find it sad that many of those who post do not enlighten us who try to help if/when they achieve a "solution" to their problem.

Sorry that I give you wrong eBay item number. The correct eBay number is 371829265599. But this item number could be change after item Buy It Now have ended. If you search on eBay "Malibu Transformer Photo Cell Sensor", you will find it. Hope this will help you.
