My stir plate is quite old it appears as though the potentiometer is shot. I tried cleaning the ring on the back of it, but it has no impact on it. It is basically working like a switch between off and on at full bore.
So I need to replace the potentiometer; however, it does not say on it anywhere what the ratings are, thus i don’t know what to replace it with. I tried googling ways to find out how to find out what i need, but i have found nothing. Can one of my savvier brewers help me on this one?
