there is your manual

and i think we should start from the begining, i dont like hearing you needed the board and thermostat(i have to assume this would be the defrost therm cause the fridge has no control thermostat)

the manual explains how to force defrost from the controls, this test must be done while the freezer is cold

once you have some frost on the evaporator remove the freezer back then run the force defrost test and see if the heater gets hot... post back your findings

i'll try to check in nightly for you to make sure you need a board before i ship one out

as for the change in board and UI, sorry but i do not know the reason nor do the engineers tell us the reason, but i sure would like for them to explain why they caused such a PITA

i can say that i do not see many failures with these boards, and i do friggy warranty so i see alot of these units, the common failure is the defrost thermostat which we will test next if your forced defrost produces no heat from the element

p.s  i hope your skiny cause its tough gettin inside that freezer, but have faith, cause i think you had a first technician failure and not board failure

btw, i have not explained any real test procedures yet

before i bother... do you know how to use a multimeter to test for voltage and continuity?

if not i can explain a simple defrost therm bypass test

but the meter test does all at once and is prefered

I'm sorry but I don't own a multimeter.  :(

But I was watching when the repairman was in the freezer and he seemed to determine the thermostat was bad by using a multimeter. I think I read the other day there is a forced defrost procedure by pressing the temp control buttons a certain way, I can't recall, but is that the alternate test procedure you mentioned?

And I also found it odd that the repairman tested the thermostat with a multimeter, then just slid out the control board and determined it was bad just by looking at it.

the manual i sent describes the force defrost key combination, you must remove back panel of freezer then run force defrost from the controls for your first test

*note* the freezer must be cold still once freezer back is removed when you run the force defrost from the controls

quick explanation....  the defrost thermostat is closed when cold and allows the heater to get hot and melt the frost, once the heater gets hot enough(47 degrees i believe) it opens and turns off the heater

so if the freezer is not cold when you force defrost the heater wont come on cause the therm is open

so, back to the begining

remove freezer back while fridge is running, then do forced defrost while the fridge is on, check heater after 2 minutes and it should be hot to the touch(caution you might burn yourself)

post back once you do this

btw, when you force defrost the fridge should shut down(freezer fan and compressor)  make sure both are off, i have seen a few friggy fridges that had bad boards and ran the compressor during defrost, this causes frost build up even if the heater and therm are working

you can check the compressor to see if it is running by simply putting your hand on top and feeling for the slight vibration

you might have to buy a cheap multimeter and find or section on "how to use am meter" for future tests, but i will try easy tests that require no meter as long as i can till these are no longer usefull

But I was watching when the repairman was in the freezer and he seemed to determine the thermostat was bad by using a multimeter<---- if your fridge was warm at the time he should not have bothered to do this test cause the therm would test open

Wow, thats definitely a good start. The fridge was definitely warm when he tested.

And I will be doing these tests tomorrow. I just took off the back panel and the evaporator is all frozen up again, though the freezer was still maintaining -3F before I checked.

Thank you so much for taking all this time to write that out.

I'm assuming the evaporator shouldn't look like this?

i'll check your reply tomorrow eve

btw, its not every night i'm on these wee hours, i napped all afternoon/eve with my sick boy so wasn't tired, prolly pay for this in the mornin

after tests, place freezer back in its place but dont screw it back in cause i'll be askin you to do things back there

tomorrow make sure you purcase a few wire connectors if you dont have any, marettes or preferably crimp on wire connectors if you have the crimper

cause i will be asking you to cut and splice 2 wires for the next test if forced defrost provides no heat to the element

give one more pic closer to the top, where the wires are going to the disk on the top evaporator tubing
