You didn`t write if your a/c got a lower voltage than your electricity line.and also,if it is for the low voltage supply for it`s control circuit,you`d better taka a look for the value of capacitor around the transformer(adaptor) so that we can identify it` proper value

Can the two transformers be hooked in parallel to service a 500 W zone?


If you are talking about low voltage light transformers, then answer is probably NO... but you could try it and see if it works... but I am almost certain that both transformers will probably burn out.
Output is 12 Volt AC... the transformer coils will probably burn out because the waveform from each transformer cannot be guaranteed to be the same.... even if both transformers are seemingly identical and plugged into same outlet.

For additional information, read transformer installation tips on following page.
http://waterheatertimer.org/Malibu-power-pack-stopped-working.html#install

Power company transformers can be wired together in specific ways to produce 3-phase waveform, but these transformers are specifically engineered for the task. And the transformers do not combine the output (as you would be doing with yard transformer), instead each power company transformer produces 1 leg of power in a 3-leg power supply.

How to test for bad transformer


  1. To test a transformer you need to know what type of transformer it is first. There is a step up transformer which steps the voltage up and a step down transformer which steps the voltage down.
  2. You will still test the transformers the same way for step up and step down transformers. If it is a step up transformer apply the incoming power to the transformer or plug it up. Now take your multimeter and place it on the AC volt scale and test the voltage if the voltage on the data plate says the transformer should step up to 220 volts and it doesn't then your transformer is bad.
  3. Now repeat the same steps for a step down transformer. Plug up the incoming or primary power and test voltage on the outcoming or secondary side the voltage should step down to the proper value. If you don't read any voltage on the secondary or outgoing side then the transformer is bad.
  4. To read the voltage place the two meter leads on the secondary side, or the side you will plug your equipment into. If the secondary side is an outlet then place the two meter leads into the top two slots in the plug and read voltage. You also want to make sure the incoming power is working as well. Otherwise you will be reading a bad reading every time.

How easy is it to replace an intermatic ML300RTW malibu tranformer?


Question is not 100% clear.
Add a comment any time, and that sends email, and I will respond with more information if needed.

1) Are you trying to repair a transformer?
I do not know of any repair for the transformer, or available parts sold to repair transformer, although the product does have a warranty, and Intermatic might have a repair protocol for the transformer.
http://www.intermatic.com/customer%20service.aspx

2) Are you replacing existing transformer with a new transformer?
The transformer plugs directly into outdoor outlet, and wires are connected to A and B terminals.
