hello

Frigidaire model LFSS2612TE0
freezer has stayed right at 20 degrees for several days -

Compressor is running
Defrost Heater assembly passed an ohm test
Same with the thermistor
I replaced the Defrost Thermostat
Evaporator fan runs, Condenser fan runs
Door seals seem fine
Cleaned everything under the cardboard back

any ideas - thanks

Hi, Only 3 parts control the defrost cycle, the defrost thermostat, defrost heater, and control board. If the defrost heater ohm tests good and the defrost thermostat ohm tests good while its frosty(or in a glass of ice water, waiting at least 5 minutes before ohm testing it) then the problem is your control board.

I know you said you already replaced the defrost thermostat, but I'd still ohm the new defrost thermostat for continuity(0 ohms) WHILE ITS FROSTY(or in a glass of ice water, waiting at least 5 minutes before ohm testing it) while the refrigerator is unplugged.

Here's the defrost thermostat for your model:
5303918214 Defrost Thermostat


There is a video when you click the part link to the defrost thermostat, it shows where its at.

Watch this video: Defrost Thermostat Ohm Testing Video If it's frosty you don't need to remove it and put it in ice water to ohm test it.

If it has no quick disconnect, you will have to cut the wires and splice back the insulation a little, don't cut to close to the defrost thermostat itself as you will need 2 wire nuts to connect the spliced wires back together.

If both the defrost thermostat and defrost heater ohm test good, then it can ONLY be a bad control board.

Here's the control board for your model:
A01078804 Control,electonic,w/cover

The pic of your freezer looks similar to mine. My freezer is fluctuating from 0 to 25 which apparently indicates the freezer thermistor. I have the parts assembly drawing but it does not indicate location. I cannot locate it unless it is inside or behind the ice maker. Where exactly did you find the freezer thermistor for your test?

Thanks

thanks Jake - I have been watch and it defrost cycle does come on - maybe just not often enough - will check ohm in a bit -

If the defrost heater does come on, then your defrost thermostat and defrost heater are both good, then only part left would be the control board that would be the culprit.
