Thermoelectric wine cooler drying and curing - DIY

is the dehum wired backwards (unsure if the plate allows it) its that or you have a hole that the dehum is pulling outside humidity thru imo

dont think so but will double check later on. no hole in this fridge since its actually the first one i used to build(ive done 2 rounds of drying/curing with the fridge) but just swapped out the dehumidifier to a slightly bigger one and i put the old dehumidifier unit in the new koolatron build. the new unit seems to only work with one wiring configuration that took me a few hours to figure out. def not savy enough with electrical wiring to know if its wired wrong and will try to post some pics tonight of the unit.

sp most im not sure if all dehum use a TEC: A thermoelectric cooler (TEC), also known as a Peltier module, is a solid-state heat pump that uses the Peltier effect to transfer heat from one surface to another when a DC electrical current is applied. The device creates a temperature difference, with one side becoming cold and the other hot, allowing for precise temperature control in various applications like electronics cooling, medical equipment, and portable coolers.

They use volts DC as voltage is applied to the plate one side gets hot one side gets cold. most are not marked with what voltage or amperage they need to operate which sucks but there are ways to figure it out, like mine had no break down because the companies don't want you to see how easy they are to make, but they are very simple DC systems, they will either have a AC to DC convertor in the plug or inside the unit. if you post some pictures i can try to help you out.
