Hi @stevers1805 , Something doesn’t add up with the figures. 18KWh/day averages to 750W x 24 hour of continuous operation. Yet when the compressor is running and also presumably the evaporator fan will be as well etc the total is only 40W, which would only equal 0.96KWh /day if the compressor was running continually and it isn’t as you say that it shows 0W occasionally. You may need to check the refrigerator when it is in its defrost cycle because then the compressor will be stopped as will the evaporator fan but the defrost heater will be turned on and this may draw more current than the compressor. I don’t know your refrigerator but with most auto defrost fridges the defrost cycle occurs approx once every 10 hours. When it happens the compressor and evap fan are both stopped and the defrost heater is turned on to melt the accumulated ice from the evap unit which drains to the evap pan under the fridge. At the end of the defrost cycle the defrost heater is turned off and the compressor and evaporator fan are both turned back on again to drive the temps back down to the set temp. The whole process takes about 15-20 minutes. The temp in the freezer section is allowed to rise to aid the melting of the ice so if you place a thermometer in the freezer and the compressor is stopped and you notice that the temp is heading towards 0 deg. C instead of hovering about -18 C then most probably it is in defrost mode and not just stopped because the temps are OK, so check the energy meter and see what it registers. I can’t find a service manual for the refrigerator as usually they show how to “force” a defrost cycle so that you don’t have to wait to check it. You may have better luck in finding one. Just trying to eliminate possibilities
