12V Refigerator Questions

[SternWake]

I use one of these:

to see the temps in different parts of the fridge. Before I added a 40mm ~6cfm 0.03amp internal fan the floor would be 31f and the warmest spot in the fridge would be 44f or higher. After fan installation all portions of the internals were within 1.5 degrees f of each other, and I was able to turn the dial down a bit from ~3.5 to 2.3 to hold sub 36.5f internals. It also helps cool down items placed within faster which can help reduce battery consumption overnight when there is solar excess in the daytime.

These IR temp guns are also handy for other things like finding high resistance electrical connections or failing wheel bearings.

It would be nice being able to see fridge temps without opening the door, but if the sensors/senders fail quickly and the location of install is not indicative of the high and low temp spots then one is kinda flying blind.

You have a front-loader right Sternwake? I don't see how that would work for my top-loader. I'd have to half unload it to use the temp gun.

Yep, a front loader. These probably have higher variance of internal temps within than a chest type.

Merely presented the option of the IR temp gun as they are useful for other things. My old man gave me one and I have found it to be extremely useful.
