My chest freezer runs 24/7 I have replaced the seal and have check that the thermostat switch off. Should I have the gas checked?

in order for the "stat" to sense the coldness of the freezer box it needs to be within the chilled space. it is probably held on by a couple of clips on the underside of the freezer compartment on the evaporator plate.

Remove the panel covering the compressor. Remove the relay plugged on the side of the compressor and shake it. If it rattles or has any burned spots it is shorted out. Try replacing it first. Make sure you replace it with the correct replacement, not a fit-all. If this is not the problem you will need to replace the compressor. If it is less than 5 yrs old the compressor should still be in warranty. If so call Sears, it will be repaired free of charge. If it is out of warranty buy a new freezer.

ice cream is always the last to freeze and a temp of minus -10 degrees is usually required to get it to get hard. if you put the ice cream in the door it will be especially tough to freeze. a good thermometor is a good investment as you can observe the temps. usually ten degrees or 20 degrees is what they run. yes they do cycle on and off as long as they hold temps thats good. the outside of the freezer gets warm because the hot compressed refrigerant is spread through piping near its surface giving up its heat of compression . setting the stat to max will freeze the ice cream eventually but utility bill suffers . good luck

if the box has mold between the seal and liner the the seal isn't the main problem, the main problem is the liner is bad and by time you got both parts if you can it would cost more than to replace the freezer.

home refrigeration units are not designed to work in low temperature areas. where temps will drop below 45f so that is your problem. this is listed in your owners manual if you want to verify. thx peyton
