Fridge door closing magnet

My fridge door would sometimes stop just short of closing fully. It was a small problem, but the result was annoying: the door could look almost closed while the seal had not fully taken over.

I considered a few possible fixes, including tipping the fridge back slightly, adding an alarm, or designing a retracting magnet mechanism. Those options would have added complexity or solved the problem after it happened rather than helping the door close properly in the first place.

The simpler answer came from looking more carefully at the fridge itself. I noticed an unused feature from the reversible-door design: a spot where the door hardware could have been mounted if the hinge direction were changed. That gave me a clean place to attach a small helper without modifying the main door or cabinet.

I designed and 3D printed a small holder for rare earth magnets. The magnets provide just enough pull to bring the door through the last bit of travel so the edge gasket can take over and seal the door normally.

It is a small project, but it captures a useful design pattern: look at the actual object, notice the features that are already available, and choose the simplest physical intervention that solves the real failure mode.

Fridge circulation fan

My Danby all-fridge was freezing food on the lower shelf while the rest of the cabinet stayed at a normal temperature. The drain was clear, and the fridge appeared to be operating normally, so the problem was not obvious from a standard check.

I used a thermal camera to look at what was actually happening inside the cabinet. The images showed cold air pooling near the lower back of the fridge. The unit relied mostly on natural convection rather than a built-in circulation fan, so the coldest air was not mixing evenly through the cabinet.

The fix was a small targeted airflow improvement rather than a major appliance modification. I added a low-voltage fan on a custom 3D-printed bracket to gently circulate air through the cabinet. I also added a small thermal switch attached to the compressor so the fan only runs when the fridge is actively cooling.

The result was a more even temperature distribution and a practical fix for a frustrating problem. It is a small project, but it shows a useful pattern: diagnose the actual system behaviour, avoid unnecessary complexity, and make a targeted physical improvement that matches the real failure mode.

And now I have no excuse not to eat my vegetables.
