Main Control Board

UNPLUG! (Read Instructions for wiring configuration) Remove cover lower back right hand side.Remove ribbon plugs top and bottom you will need to lever back holding tab while pulling plug they will more than likely break dont worry you are throwing this part away., disconnect ground wire, compress plastic holding tabs,
pull off control board, plug in new board push on to holding tabs reconnect ground and turn on refrigerator and check replace cover, everything is now working great.

I removed the board, unplugged all the sockets, took the new board, plugged in all the sockets, and replaced the new board into the refrigerator. I was to applaud this business. I was first able to diagnose the problem by finding this site, then one of the customers explained how to fix the problem ourselves. It save us at least $100. The $25 overnight shipping fee was well worth it. We could have lost $100's of dollars worth of food.

From Google to PartsSelect. Reading the forum, the consensus was that to fix the nonworking dispensers the main refrigerator motherboard had to be replaced. I ordered it which is easy to do because the diagrams show all the parts clearly. Great website. I also ordered the front trim piece because I had snapped one of the prongs holding it on. They arrived quickly. The trim just snaps on the front which takes a few seconds. The motherboard which is just a circuit board, even came with replacement instructions. It takes a few minutes to wheel the refrigerator out, then take off the back panel (3 screws), unplug all the connectors, unsnap the circuit board, snap the new one in, plug the connectors in, reattach the back panel, and wheel the refrigerator back to the wall.

The water dispenser promptly froze up. To make sure that it is not the solenoid valve, unhook the water hose under the freezer door. Pressing in the water dispenser should pump water out of the hose onto the floor. It did for me. Since there is only plastic tubing after that, it has to be clogged with ice. I took a thermocouple, inserted the wire into the water dispenser outlet, it would only go in about 3 inches and displayed 31 F. I took a plastic funnel which slipped onto the end of the outlet and used a blow dryer to heat up the outlet a lot several times. Eventually the ice unfroze and it has been working ever since. I think if this happens again, I'll get a cheap aquarium aerator to pump air, for the hours it might take, through a thin tube (using wire insulation) to the frozen spot to melt the ice.

While the refrigerator was away from the wall, I took off the screws holding the large bottom panel in the back off. This exposes the condenser cooling which visually needed to be cleaned off with a vacuum cleaner. After doing this, it seemed to make the refrigerator run much more efficiently.

The refrigerator has been working perfectly for past month and it makes me so happy.

Simple; Removed the panel, unplugged the cable connections to the mother board with a rat nosed plier.
Then to remove board you must squeeze closed the 4 plastic retainer clips in each corner, or they can accidentally be pulled off with the board.
Removed the board, re-attached the new board on the clips, then the cable connectors, then the panel.
Plugged in the refrige and it has been silent ever since.
Follow the instructions and anyone can do it.

Remove back panel to expose the control board. Simply unplug cables from old board and pull the board out, no tools required. Put new board in place and replace the cables. Very easy.

Removed main control board cover on back of refrigerator (3 screws). Unplugged power to refrigerator and removed electrical connections to control board using a screwdriver. Using a screwdriver disconnected (4) plastic self -locking prongs holding the board. Matched new replacement board with old board. Plugged in electrical connections to new board. Snapped main control board onto (4) self- locking prongs. Reinstalled cover (3) screws. Plugged in refrigerator and tested refrigerator operation.

I replaced the display board by accident to find out that there is a big board in the rear of the unit. Order and replaced it well not fixed and still doing the same thing. three hundred dollars later and i am ready to push it out the door and get a old school fridge without all the electronic bs. at least they work and last. what a concept.

pulled the board away from the 4 plastic pins, unplugged the wires and plugged them directly into the new noard, pushed board back onto the four plastic pins.......job completed in under 5 minutes. Fridge working fine now for over a week......no problems.

Removed the board cover from the back, removed old board, installed new board, installed cover.

Pulled out the fridge and unplugged electric cord. Took off the back lower right side panel. Unplugged all the connectors and removed the motherboard. Replaced the motherboard and reconnected connectors. Replaced the panel and plugged it in. Works great!

Removed cover plate on rear of unit - 3 screws

Removed connectors and ground wire

Removed board (use needle-nose pliers to compress plastic mountig posts)

Replaced board, inserted connectors, attached ground wire, put cover on

Everything worked properly

Diagnosis of symptoms was condenser fan not running, due to faulty main board.

First: removed the cover over the main board, which was too hot to touch. Bad design flaw, no ventilation for the board, which I believe made it fail. We got another year of service with the cover removed.

Second: after reading people's experiences here, ordered the board and popped it in. (Note: needed a pliers to compress each of the 4 plastic studs holding the board in.) Works like a champ.

Third: did NOT replace the cover. At our altitude the air can't conduct enough heat to prevent cooking the board. Need to allow circulation.

Removed back cover from unit. unpluged wirring harness installed new control board and refigerator runs lik new

For troubleshooting, I took off rear panel inside of the freezer compartment & determined that icing of the coils was not the problem & it did not apprear to be a defroster malfunction. All components appeared to be working properly except the compressor would not turn on and only room temperature air was being circulated by the fan. After narrowing the probable causes down to a faulty Main control board by reading as many similar posts as possible,I ordered the new control board. When it arrived the following morning via UPS(less than 24 hours!), I unplugged the wiring connections attached to the old board, (which was somewhat different in appearance), and then gently popped the circuit board off of the plastic retainer studs by pushing in the little retaining clip part of the studs in with a small screwdriver so the board could be released easier as I pulled outward. I popped the new board on the studs by gently & evenly pushing with a larger hut driver over the studs until it was locked in, being careful not to damage or over stress/bend the board. I placed the wiring connecters onto the pins on the board.....every connecter had a different amount of pins so improper connection was not possible. I placed the ground wire connection of the new board between the metal cover plate @ an adjacent screw location to ensure grounding to the back of the fridge sheet metal. I plugged in the refrigerator and was quite relieved when I heard the compressor start up after a second or two! Within moments the temp began to fall until it reached the proper temp in both compartments. Success!

I AM A SINGLE MOM OF TWO WITH LIMITED FUNDS. I HAD A REPAIRMAN COME OUT AND FIND THE PROBLEM AND GIVE AN ESTIMATE. WE WERE TOLD THAT IT WAS THE EVAPORATOR FAN MOTOR AND AND THE MAIN CONTROL BOARD. THE REPAIR WOULD COST $400 AND NO GUARANTEE. SO I CHECKED THE COST OF PARTS AND IT WAS $200 SO FOR NO GUARANTEE I FIGURED WHY NOT TRY IT MYSELF AND POSSIBLY SAVE $200. SO I ORDERED THE PARTS FROM PARTSELECT. EVEN THOUGH I PAID THE CHEAPEST POSTAGE THEY ARRIVED THE NEXT DAY. SO FROM WHAT I READ AND SAW THIS WOULD BE A PIECE OF CAKE. WELL LET ME JUST SAY IF THE FREEZER SECTION WAS GUTTED TO BEGIN WITH IT MIGHT NOT HAVE BEEN THAT BIG OF A DEAL. AS IT WAS GETTING TO THE TOP SCREWS OF THE PANEL THAT COVERS THE EVAPORATOR FAN REQUIRED THE REMOVAL OF THE ICEMAKER AND ALL. I AM NOT A TALL WOMAN NOR AM I A THIN WOMAN AND FITTING MY BODY IN THAT SMALL FREEZER SECTION WAS NOT EASY. THERE WERE TIMES THAT I HAD TO HAVE MY TEENAGERS REACH A LONG ARM IN AND HOLD A PART UP FOR ME. AFTER THAT I DISCOVERED THAT THE FAN I HAD PURCHASED ONLY HAD 4 WIRES. THE ONE FROM MY OLD FAN HAD 6. I DISCOVERED THAT 2 OF THE WIRES WENT TO SOME SORT OF SENSOR. LONG STORY SHORT I RIGGED IT. I WAS ABLE TO REMOVE THE 2 PRONGS FOR THE SENSOR AND INSERT THEM INTO THE EMPTY HOLES ON THE NEW FAN HARNESS. IT WASNT EASY. I HAVE LIMITED TOOLS TOO AND I WONT EVEN GET INTO HOW I DID IT. THEY DID NOT FIT THE GREATEST SO I USED THE ELECTRICAL TAPE TO COVER THE WHOLE CONNECTION. I PUT THE WHOLE THING BACK TOGETHER AND DEBATED ON TRYING IT WITHOUT PUTTING IN THE MAIN BOARD BUT I DECIDED TO TRUST THE REPAIRMAN THIS TIME AND GO FOR IT. GETTING TO THE MAIN BOARD WAS NO BIG DEAL. BUT WHAT DISTURBED ME WAS THE MAIN BOARD I HELD IN MY HANDS DID NOT LOOK EXACTLY LIKE THE MAIN BOARD I WAS ABOUT TO TAKE OUT. I WATCHED THE VIDEO 3 TIMES MY HOW EASY IT LOOKED. I THEN READ THE DIRECTIONS THAT CAME WITH IT. IT TALKED ABOUT REMOVING A PIN AND CUTTING A WIRE. WELL I ABOUT HAD A STROKE WORRYING. I FINALLY FOUND THE SERIAL # ON MY FRIG AND THANKFULLY MINE WAS NOT ON THE LIST. HOWEVER THE DIRECTIONS DID STILL SAY SOMETHING ABOUT IF THERE WASNT A WIRE IN PIN 2 PROCEED TO STEP 3. WELL I HAD A WIRE IN PIN 2. SO IT WAS CONFUSING. MY SERIAL # WASNT ONE OF THE MODELS #'S GIVEN BUT I DID HAVE A WIRE IN PIN 2. I JUST TOOK A CHANCE AND TRUSTED THE SERIAL #'S AND IGNORED THE REST OF IT. I PLUGGED THE WIRES ON THE NEW BOARD ONE AT A TIME. PUT THE COVER BACK ON AND PRAYED AS I PLUGGED IT IN. A SOFT PURR BEGAN. IT WAS RUNNING. THE FREEZER WAS AROUND 60 DEGREES. I PUT A ROOM THERMOMETER IN TO MAKE SURE IT WAS GOING DOWN. IT KEPT GOING DOWN. AROUND 3 HOURS AFTER I FINISHED THERE WAS A LOUD NOISE FROM THE FREEZER. IT HAD MADE ICE SOMETHING IT HAD NOT DONE IN MONTHS. I STAYED AWAKE MOST OF THE NIGHT WATCHING AND LISTENING TO IT. IT GOT DOWN IN THE SINGLE DIGITS I WAS AFRAID THAT MAYBE IT WOULD NEVER SHUT OFF. IT FINALLY SHUT OFF AS I WAS MAKING THE KIDS BREAKFAST THE NEXT MORNING. OF COURSE I WAS WORRIED THAT IT WOULD NOT RESTART. SO I OPENED THE FREEZER AND FANNED IN ROOM AIR. IT WORKED. SINCE THEN WE HAVE PURCHASED NO MORE DRY ICE OR REGULAR ICE. WE BOUGHT A TUB OF ICE CREAM AND MORE THAN ONE DAY OF SCHOOL LUNCH STUFF AT A TIME. BOTTOM LINE IT WORKS. THANKS TO EVERYONES POST AND TO PARTSELECT FOR THE VIDEO. I HOPE THAT I NEVER HAVE TO DO IT AGAIN THOUGH.
