ok my freezer is control temp inside the fridge ...so if high is it my freezer colder or lower... all I know is it is full of ice where I can hardly get anything in or out ... if I want to defrost my freezer what should i put the control on ... + do not want things in the frig to spoil ... I have done both nothing seems to be working ... and shakes head ...

step one see if it has a manual defrost button. if not, all food into the coolers and out on the porch. then turn off the whole thing and leave the door open . ps try not to let the melting ice flood the kitchen lol.
as for the temp setting typically the higher the number the colder it is.

You will have 2 sets of controls, Freezer and Refrigerator; each
operates independently of the other (though if you turn off just
one the other might have to work harder in general) so you should
empty and turn off the Freezer (or lowest possible setting) when
ready to defrost..might take a few days for the ice to start melting.

Higher markings mean colder temperatures..lower markings mean
warmer temperatures.

What I would do is, look up the manufacturer online, they always
have their manuals there (usually PDFfiles) and see what they
have to say ;-)

oooh soufie buys expensive fridges with dual controls

thanks to you both ... its a old one don't think I have the duel settings ... my dad sent me $ long ago to buy it ... really sentimental... I keep Ice bags in the freezer for when we had a lot of power outages lost a lot of food ... at this point i should just try an clean out the food ... all very frosty anyway lmao

if it is frosty not icey you can scrape out the worst of it with a plastic spatula first.
i have even used a hair drier to melt it faster

Ahh I thought you indicated the Freezer controls were in the
Refrigerator along with the Refrigerator controls.

So if they are both on one dial, I would suppose that the
Freezer gets colder if the Refrigerator gets colder and
vice-versa.

Trick here is to defrost really fast, a hair-dryer works
better than a chisel..but it looks like you have to suffer
the Refrigerator drop in temperature to Defrost!

Holy chit we are both channeling Martha Stewart,
wrote both replies before seeing yours hahaha

Nice to hold onto those sentimental items if we can ;-)

You're on line. Do a google search for the brand name refer ya got. It never ceases to amaze me the amount of technical info you can get on line.
