Thanks RegUS_PatOff. Looked at refer today. Unit is working normally, icemaker loaded with booKoos of ice. Frdige temps normal. Have probably a drain problem, freezer floor frozen with ice puddle, water sometimes leaks out of door. Easy fix.

Main complaint Problem is no digital displays at User interface cold control board. Can not read diagnostic display. What do you suggest, Main control replacement or user interface board? Better yet, How would one diagnose/test these boards?

Make sure the 2-pin and the 9- pin molex connectors on the user display board are tightly inserted. Make sure the pins are not pushing backwards out of the connections as they are being connected. Make sure that the door switch wires are connected to the door switch itself tight . Use your multimeter meter to check this. Make sure you are getting full 120 vac to the door switch from the blk/red wire to the bare ground of the upper door hinge green wire.(under the hinge cap). Make sure that the control board connections themselves are tight.

If all that checks out, then replace the user interface board:

Update:  Connectors all tight,  Receptical voltage122v, Voltage @ refer door switch to chassis ground 120v.   No voltage to refer light,  Voltage (and continuity) across door switch.  Compressor cycles.  No light display @ user control panel.  Evaporator & condensor fans work.  frezzer makes ice, optical emitters working, ice dispensor & water working.  Defrost system working, bottom of freezer full of freezing water.  Evaporator drain frozen, cleaned & defrosted using steam gun thanks to Samurai.

 

Replaced user control panal with new one.  Display lights come on for maybe 30 seconds, then go out.  No refer  light comes on at user control panel.  Compressor comes on.  Turn fridgerator control off, compressor resets, turn control back on,  display lights cycle back on, then blank again.  tried over & over same thing.   What gives?    Do I need to replace the main contol board?  

 

Put old user interface panel back in refer,  no display lights on whatsoever.  Compressor runs, fans work, freezer freezing, drain draining, frezzer lights working refer light not.    Clueless.   Patricio.

I know you said you checked it but

 

sounds like a bad door light switch or a problem with the wiring to that switch

 

if the refer door switch does not work the display will go blank after a few seconds

 

add to that , did you say the refer side inside light was out ?

add

the drain was frozen ?

 

you may have a drain heater on that one !

 

look on your wiring sheet , anything common with the light , a drain heater , powers , commons ?

 

None of this may apply , just the direction i would go if it was my nightmare .

 

PS: just looking at your wiring sheet

i see no drain heater

i would quickly check the threads of the fridge light bulb socket with an ohm meter to the "N" side of the power plug

the center pole on the bulb socket to the switch (ohm out)

ohm out the other 2 wires that go to the motherboard from the door switch (i know this is a pain in the butt , but you need to be sure )

if it's all good , 0 ohms the only thing left is the motherboard

 

sorry , i feel your pain

 OK making my list:

1st: Continuity check on light bulb socket

2nd: Continuity on switch to main control board

 

Found dead mice under refer so there is probably chewed wires.  Note: customer says refer was in barn & they had mice problems, unit is in garage presently.

How would you check continuty fromdoor switch inside fridge to contol panel on bottom backside, make longer leads?

 

Also customer says that control board was making clicking noises when display went out.  Has been out for a long time.  Not making noise now.

 

More questions later it is late & I have to be up in 5 hours (4am)

[Cactus Bob]

to check the two wires that go from the door switch to the motherboard

 

first , remove the two wires from the motherboard , short them together with a jumper

 

check for 0 ohms at the wire side of the door switch connections
