immersun repair -no.3

Thank you all for your help, please see photos and U5 slot is what we need to know is please. Thank you

Marcus- U5 not U2.

Looks like your pcb.

Ah, yes, the MK1. Actually looks like a very similar failure to this one (triac, current sensor & opto I'm guessing, but haven't investigated yet).

Luckily U5 is still readable on this one even though one of it's legs has gone: ACS712T 20A current sensor.

Thank you Marcus for your help, hopefully it will be working soon

And are these faults all caused by excessive hours in diversion mode?

Can you add heat sinks to heat sinks ( bolt on)to give more capacity, or is it easier to rig up fans as others have done?

difficult to say. The one here was closed in a cupboard along with a 3Kw inverter, so maybe high temperature played a part. But it worked ok there for several years.

This is a million to one shot. My immersun has given up the ghost. Seven years old. It suited my needs and I miss it. Had it disconnected for safety but would love to find someone near me who could repair rather than have to replace. Would rather pay a hundred than several hundred in these times. Live South England. Bath area.
Any suggestions please

Hi everyone
As you can see from my photos above I still have issues with getting the immersun working again, would anyone have a working PCB from the same model as mine or one they are certain would work in my model? Thank you all for your help, anyone please?
