I tried posting this before with no avail, I need help identifying a component and how to test it. If it's bad I also need help knowing where to buy a replacement. What is this components name? How do I test it? And how to order another? Also any other help with how to test and fix this inverter board is appreciated. Thanks in advance for any help.

It looks like some sort of coupled inductor but I cannot quite read the part details.

They are vanishingly unlikely to be the problem (As in I have never seen a failure that was not mechanically obvious).
Looks like the circuit is some sort of polyphase bridge thing from what I can see.

Thanks for ypur response. So if it is an inductor how would I test it? I used an digital ohm meter on three different settings. I tested it from every aspect, never has any of the test brought any resistance readings except were they are connected to the same spot, then I have a .1 ohm reading showing that it is indeed connected to the same spot. But on the oposing side of the inductor there are no readings....ohms cirtuit, diode/resistor setting nothing, uf reading no reading am I testing this wrong or are they bad? My dmm reads all the other capacitors and diodes etc accurately... Thanks for any advice..

I responded by posting another thread, I'm still learning how to use this site. Please read my next thread thanks..
