Disconnecting J4 at motherboard won't eliminate this as a problem?

 

Replacing Climate Control Board is not only expensive, it's also out off stock.

There are pictures of Evap frost pattern from when I first attempted to fix defrost problem 2 years ago here>

 http://appliantology...eg/#entry231518

I've been manually defrosting ever since.

 

I've ordered 4 new thermistors and a new motherboard.

Both (comp. & evap.) fans seem to work fine.  Should I replace them both or wait till I have a new motherboard? :rolleyes:  

I will disconnect climate control board. That is J4 on motherboard, correct? This is all I need to do to take it out of the equation? :rolleyes:

I cut out the 4 thermistors 2 in the FF and 1 on the evaporator and ! in freezer compartment. At room temperature (70degrees) they all read between 5.2K to 5.5K ohms.

In a cup of ice water they all read between 14.8K to 15.8K ohms.

Seems good to me?  :rolleyes:

The defrost heater reads 40 ohms. 

Both doors seal good when closed.

Evaporator pan/heater drains good when manually defrosted with jumper, at least water fills compressor pan.

Could the nonworking Climate Control Drawer have something to do with it? :rolleyes:

 

Not sure what to do? :rolleyes:

I'll replace the 4 Thermistors. Should I also replace the overtemp thermostat? could this be shutting down the heater at to cool a temperature? :rolleyes: 

If problem persists after this I''l replace the Motherboard for the (3rd time).

Am I missing anything? :rolleyes:

For the past 3 years I've been jumping the J9 to J11 terminal on motherboard to defrost the coils.  This needs to happen every couple of days and takes about 2 hours. If I put my fingers in the dampner door I can break out the ice, also at the intake vent I can see ice. Temps are approx. -8 and 40 degrees when I resort to jumping defroster every couple days.

I've replaced the mother board (twice) and the water tray with heater below the coils (it drains fine). When I put frig in diagnostic mode everything seems to check out okay. The Climate Control Drawer has no  led readout and has not worked since before defrost problem.

I got a spare refrigerator yesterday. I'm ready to fix this problem NOW. Where do I start? Replace all Thermistors? Replace all heaters?

:woot: Point me in the right direction I'm ready to go.

To test them in ice water I need to cut them out? Then solder them back in. Seems it would be best just to replace them if you have to do all that.
