Yours is a totally different model. Yours has the 240V AC powersupply built in to the Compressor control module on the side of the compressor.

Yours should have a 101N0500 controller like this fitted. If you have 12V at the 12V terminals & it wont go, then the unit is faulty & will need replacing. The one in the picture works on 12V DC but the 240V AC side is faulty (Major Meltdown)
yer thats the one i have, it has 12v at the terminals so i assume i need a new 101N0500 controller, if you can still get them and there worth buying :(

Yes they are still available but not cheep.

probably better off running inverter in car an using 240v
would it be better option to get the circuit board looked at my electronics guy or just run inverter

You could try your local electronics guy. This is whats inside it.
I did mark some of the components on the 12V side of things some time ago.
Ive tested both these items and they both seem to have 12v on each side.Do you know what they are worth off the top of your head, I cant seem to find one for sale.

Heres a picture of the 2 components. Voltage was measured using 12V DC to power it. Voltages as marked. Parts probably available on Ebay cheep.
mmmm the IRL3705ZS at the back has 12v like it should but it also has 11.78v on left pin and 12.6v on right pin
also the 12CWQ10FN is working ok
if that makes sense :)
I did find a replacement but it is 86A not 75A Click Here

The replacement one should be fine. I am interested in your outcomes as to wheather it fixes the problem. It may well be what switches the power feed from the 240V supply to the 12V supply. I cant check that as mine only works on 12V now as the 240V AC power supply has burnt out so I removed most of those parts from the board.

yer for $4 ill give it ago and report back, might take a few days, thanks for the help

This is a block diagram of those units, & that's all ive got.
can you just confirm which one of those transistors you think it is, I believe it the second one but the guy at rs said he thinks the first one so im not sure. (i mean which transistor in the link i posted above)

Its the first one. Heres some voltages & CRO waveform I measured with the unit powering a compressor. The MOSFET is obviously the 27V power supply when powered with 12V. IVE incorrectly marked the 2 components. sorry.

This is the correct picture. Cant delete the previous incorrect one.
haha ok no problem m8 ill check late this arvo when i get home from work, thanks

ok based on the last image you posted, all of the points i tested had 12.5v except for the one you have marked as 2.8v mine had 12.1v.
not sure what that means but i didnt have 27v on any of them.

Right then the MOSFET is probably faulty as it is probably what generates the 27V to run the compressor on 12V. When on 240v, the 27V is generated by the 240V SMPS.

ok so ill order this one and try an fit it lol
we said this one didnt we? IRL3705ZSPBF
Yes that's the one.
Ok.
I will have to think about this some more then & take some more measurements.
