I’m having a devil of a time getting a SSR working, and I’m wondering if anyone can offer advice? I’ve wired them up before fine, but this one just isn’t working. It’s powering a kettle element (part of a heart exchanger in a homebrew system) based on current temperature. The relay is turning on, and I’m ketting a reading of 240V at the end of the kettle lead - so it does seem to be appropriately making a circuit. However the element just doesn’t come on (I’ve tested with another lead plugged directly to mains and it’s fine). I’m a bit stuck as to why that might be, ideas I’ve played with are…
Not enough wattage getting through to the kettle element? Is this a possibility (I’ve a 13a fuse at the other end), and if so how do I fix it
Something wrong with the arduino control. When I read resistence at the SSR outputs, I’m getting oscillation between short-circuit and no-circuit. I’m plugged in to a port with PWM, but it’s just being set to ‘HIGH’ - could this be where the problem.
Anyway I’m stumped!
