I found an old 12v PC kicking about so I hooked it up to the 12v DC power supply and it all worked fine.
I butchered one of the lines in the power supply to add in an SSR and have configured my brewpi to use it, however…
The SSR turns on when heating/cooling as expected (the LED comes on), but the fan does not start up.
If I disconnect the fan while the SSR is on, swap over the positive/negative inputs, then it starts and continues running until the end of that heating/cooling period. It then stops working until I do the same thing at the next cycle.
Has anyone seen this before? Would a new fan fix it or do I need to do something else? Given the SSR can output 10A, I can’t see current being an issue?
Any help would be much appreciated!
