I have been having some issues with the low voltage cut-off on my 43L Edgestar fridge and was wondering if anyone else has run into this problem. The issue is that the low voltage cut-off engages at too high a voltage. I was doing some testing last night, and the cut-off would come on (with blinking yellow LED) when my Diehard platinum had a no-load voltage of 12.3V and a loaded voltage of about 12.1 when the compressor was cycling. If I unplug it and plug it back in, the compressor will run for about 10 minutes before it shuts down again. I was under the impression that the low voltage cut off should activate at a loaded voltage closer to 11.5V ?
I have gone through to make sure that there is not excessive resistance in the fridge wiring, it is connected to a my Aux load center with about 2m of 12AWG cable, and I have replaced the cheesy cord and connector that came with it with Anderson Power poles (I originally suspected the cord to be the problem). I really don't need the low voltage cutoff as my battery system/charge controller has this built in. Has anyone figured out a way to bypass it? From my investigations this functionality appears to be built into the thermostat/control unit. Does anyone have a schematic for this?
