We have Hotpoint Fridge 1998 and it stops after a month or two months
or more or less and then stays like that for a day or two or more and
then starts off on its own.

I have opened the Freezer panel on the evaporator coil and have found
that I can reduce the time it is off by using hair dries to remove ice
from the evaporator coil.

Other than that there is no difference in working of this fridge. I
have read about defrost timers etc but nothing correlates to this
behavior. Any suggestion. We don't use the Freezer part for meat it
has light stuff only e.g. Ice cream or some mixed veg bags and some
fries. No meat.

Any suggestion will help me get over this periodic aggravation.

Thanks,
