Re: temperature going up on freezer and frig overnight
The Unit has a defrost cycle either every six,tweelve,or twentyfour hours.It sounds like the thermal cut out is faulty located in the freezer side behind the wall where the fan is situated It is usually a steel round disk shaped sensor with two wires coming out of it.It,s purpose is to shut the power off to the defrosting element once it reaches the desired temperature to melt the ice away and them the unit cycles again after defrosting.Hope this helps.

if it is a frost free the temp will vary room temp and the warm food you put in will affect it or the electronic controler is not operating properly frost free also defrosts its self in a 24 hr time frame this will affect the flux temp
Temps should fluctuate, as the refrigerator will go into a defrost mode every so often. Some models will go into defrost mode after you open the freezer door X amount of times, say 6. So every 6th time you open the door it will go into defrost. Then some models go every 4 to 6 hours depending on settings. Then also, it is normal due to temp control. Temp setting is -10 The fridge will run to that temp setting, -10 and shut off the compressor at -10 but due to pressures it will still cool a bit to your -12. it will stay in this off mode until the temp rises 8 to 10 degs.
then kicks back on the compressor. Again due to pressures it may take the system 2 - 3 degs to catch back up and start cooling again. But you maintain average temp of -5 to -6 which is great for frozen food and saves a bit of electricity. As long as the door seals are in good shape and you clean the coils underneath once twice a year it should work fine for many years. Then lastly It may have a lag in the thermostat meaning it has gotten week or going bad. Hope this helps.
You need a multi-meter to do this. The temp.control is just a switch that closes on temperature rise and opens on temperaure fall (or when it reaches the desired temperature). Using a meter set on ohms coneect to the 2 prong ends of the temp. control. Set the temp. control on off. You should not have any ohms because hte temp. control is open (no continunity) now set the temp control to 2 or 3 and it should close (the meter will read ohms or continunity)
if it does then the t'stat works. The only other exception is the temp. control will sometimes (this is rare) not properly sense temp. for example, it fails to sense zero degrees and it will either stay on too long to shut off too soon. I only seen this happen like twice in 20 years. but more or less this is how you do it!!!
hope this was helpful
If the freezer is staying cold it sounds like a defrost system problem. A bad timer, heater or thermostat can cause frost to build up on the coils and block air flow to the refrig side. Check out ACMEHowTo.com for troubleshooting the defroster problem.
There is a small duct between the freezer and refrigerator side if this is blocked the frig side won't cool.
It is probably the control board and since it's new it's still under warranty so a certified Frigidaire repair man will fix it without charge. There should be a telephone number with the paperwork you received when you bought it.
If your frig is freezing the food in the chilling compartment as well
as the freezer, it means one thing--its thermostat isn't shutting down
the compressor when the set temperature has been met. You stated that
you had it checked by, I assume, a professional service technician.
Being a retired tech myself, I'm surprised that he didn't check this
out and discuss it with you. Check the temperature in the freezer! If
it is less than 10 degrees F., turn the thermostat to "warmer". If the
temp in the freezer is 10 degrees F., leave it alone and go to the temp
control in the frig, which is a damper that controls cold air flow from
the freezer compartment. Close this damper until your temperature in
the upper part of the refrigerator is 38 to 40 degrees F. If these
efforts don't shut down the compressor and correct your problem, then
the answer is simple. Your thermostat is bad and needs to be replaced.
It isn't expensive, and should cost you less than the labor for a tech
to install it. Good luck!
