Does that module in your first pic plug into the header on the board in your hand (3rd pic)? Try just 'scrubbing' the connections on those header pins by just plugging it in and out several times. That ESP32 chip is a SOC (system on a chip, has microprocessors, flash memory, Bluetooth and other logic that can be configured however the maker wants) that handles everything including the display. Does your fridge have Bluetooth control and does that work?
