--- Quote from: mab on September 02, 2016, 05:15:46 PM ---This is a pure guesswork, but if you replaced TH1 with the jumper, then it may be that TH1 was a negative temp coeficient thermistor (resistance goes down as temp goes up) which derates the controller as the temperature goes up. by replacing with a straight wire you're making the controller 'think' it's very hot, so it's limiting the current.

trouble is, guessing what sort of NTC thermisitor is needed.

That makes the most sense. Thank you for the suggestion. I have an extra 5k pot. Sounds like a good place to start.

I'll try it in the morning.
