Try unplugging or taking the thermistor off the fin... this will let the unit run longer so maybe the refer section will get colder. Agree with the freezer section that cold the refer should be colder. I think these things should go to hell when they die,.. as much trouble they can give us.
*My recently installed 21 cuft refrigerator uses 96 watts... measured at the input of the PSW inverter powering it. No reason to pay big $$$ for a small 12V compressor refrigerator. My duty-cycle is less than 50 percent so it will go over 24 hours on two batteries before recharging.
10 amps of solar would power it and if you put it on a timer so it only ran during the day,..then one extra battery would be enough.
