Open the door sensor, locate the reed switch, remove it and connect wires to its PCB pads. Although it should be pretty straightforward to measure the minimum distance required between the magnet and the sensor and install the magnet just a bit closer, so that any cracking of the door opens the switch. If you use a weaker magnet, the sensor will be more sensitive to the distance, so you will be able to detect smaller gaps.
Side note: if the door doesn't close when there's a small gap, the fridge might not be level or your door auto-closing mechanism might be worn out.

Did the same with Trianglelab Dragon. Damaged the heatbreak as well when disassembling the hotend. Now I own a 1.8Nm torque wrench..
DarwinFPV BabyApe is $80 and flies better than anything you’ve built 4 years ago due to improvements in Betaflight. Sure, if you want O3 you need to pay more.
