I got a peltier cooler, which stopped heating , opened up control circuit and very interesting design tactic, it feeds 12v to a dpdt switch setup as h-bridge, the switch feeds leds to show bias and in parallel with that feeds TEC module, after that , and what i found interesting was that in parallel again was a rectifier that feeds fan motors, so they dont reverse when reversing polarity, anyway i found interesting.
In series with my TEC and rectifier is a thermal sensor which seems to cut off current when TEC goes above or below temperature range, however i think it is that sensor that has fried. because when i switch to cool it never stops and when i switch to heat it never starts, there are lots of temp sensors at my vendor, but i have problem finding the specific one, or any that fit that shape
I hope someone can tell me proper name of what im looking for, maybe where to find them
I will be able to ensure specs myself , but so far cannot find anything like this item:, here is best image:
