I have a Philco No-Frost side-by-side refrigerator/freezer bought in 1970.

The freezer does not stay cold enough. I am using a freezer alarm that
goes off when the temperature gets above 15 deg F:

I can't get the freezer to stay below 15 degrees for more than a few
hours. I wrapped the alarm sensor in foam and put it at the bottom of
the freezer, consistent with the instructions.

With the freezer door open, sometimes I notice a boiling or sizzling
sound just like the sound of water dripping into a hot skillet or onto a
hot stove. Is it supposed to make that noise?
Hi,
Make sure fan and defroster heater is working normal.
