Turned a broken wine fridge into a humidor. Works good but I can’t get the temp high enough. I need 70°F but it only gets to mid 60°F with temp dial at warmed setting. If I unplug it the temp can get into the low 80’s. No good for the sticks. I’m thinking the easiest fix would be to add a resister in series with the 12vdc feed to the Peltier. But was wondering if there is a better fix to changing the temp range of the unit or is this the best way. I don’t see a need to mess with the temp much once I get it in range. A single PCL border everything. Mostly analog. Some logic but nothing programmable. A small pan with a switching supply feeding the analog driver circuit. Connected are the temp pot, a thermo sensor, an led light 2 fans Any thoughts are appreciated.
