I would not even bother with the frige from the point of electric usage.
Since maybe 98 new Gov regulations have made new units 50-75% more
efficient. I went from a double door unit that consumed 20-25$ a month
to a single door Sears that consumes 4-6$ a month. Giving literaly a
payback of several years. Even if you repair it ok door seals will be
very poor. And very possibly other things that will hurt efficiency even
more. You realy should consider what the unit costs to run that you
want, and check out new units of all types by the Yellow Energy
consumption tag, or go to www.EnergyStar.com for a complete rating of
all friges comparing utility costs to operate. At the time I bought the
Sears 19.5 it was the most efficient frige I could find, on par with a
Sun Frost. Even if you repair it now, at that age there is 1000$ worth
of more repairs looking right at you to keep you throwing money down the
drain. Id pass on that junker for many reasons.
