Refrigerator normal failed defrost stuff
Frigidaire, top freezer, 1998 model, lost cold in the bottom,
frost on the back wall of freezer.
Hoping the defrost timer was guilty, bought and changed the timer
(I know, don't just change parts without diagnosis).
Hair dryered (is this a word?) the heavy ice out of the freezer to
get to the coil thermostat and heater. Pulled out the
thermostat - good continuity when cold, broke continuity when it
got hot (over a space heater).
Fluke digital ohm meter buzzed continuity and read 27 ohms on the
heater.
Reassembled without installing the back plate or ice maker. Ran
it long enough to get everything cold, all fans working fine.
Advanced timer to defrost. Re-checked the coil thermostat, still
shows good.
Should the heater get hot to the touch? It got warm at best, and
that required imagination. Defrost time lasted about 15 minutes.
I don't want to put this thing back together if it is not right.
I don't want to just keep changing parts though I am well ahead of
buying a new unit and the work is simple while the unit is empty.
We have a back room refrigerator so we are not desperate, but wife
is saying she'll just go buy a new unit.
