Refrigerator freezer too warm; runs constantly.

Hi Jeff, Thanks for responding.
Amana BX22S5W
There was no frost at all after being on for four straight days. I am
replacing the Defrost thermostat.
A bad defrost timer -usually- will have the coils completly covered
with frost rather than bare of frost, a defrost timer stuck in defrost
will stop everything ( fans, compressor ) from running. A defrost
timer not going int odefrost woudl allow the cooling coils ot buiuld
up with frost and completewly frost over. Possible chance you opened
it up right after a defrosting cycle???? With the cover off let the
refrigerator run 30-60 minutes and check the cooiling coils, if still
bare or mostly bare this may indicate a refrigeration system problem.
and check the
Defrost Thermostat. The Defrost timer was defective per ohm meter test,
but replacing it did not solve the problem.
An over night defrost with the doors open and then turn the
refrigerator back on in the am and if it starts to work ok then you
did have an ice/frost build up.
The Refer was off for three days while we got parts and cleaned the
refer top to bottom (The bottom coil area [not condenser/coil] was very
dirty with dust/doghair - we clean it every 4 - 6 months) After new
Defrost timer was installed refer still was not running correctly. (As
stated in original post the old Defrost timer was dead.)
We used to hear popping and gurgling sounds when the refer operated. We
no longer hear these sounds. I am also, then going to check this area.
(Condenser, and Deepfreeze fan.)
Make sure the hot condensor coils are clean and not over covered with
dust, make sure the condensor fan motor is running/turninmg properly.
Both conditions are excellent. There are two fans and they both run
fine. It almost seems (to me) as though the Defrost heater elements are
on all the time. (I could be wrong.) When I just opened it up to check
the Condenser area it was immaculately clean with zero frost. It had
been on for more than four days and running continuously (I think). I
know it had run continuously for the last 16 hours except when the
Defrost timer would kick it off for about 20 minutes every 7-8 hours.
I've ordered a new Defrost Thermostat and tomorrow I will install it.
Fingers crossed.
P.S. You said "hot" condenser coils. Are these the coils under the
refer? It was very dusty there, as I stated earlier in this posting.
Yes, under the refrigerator.
