MFI2067AES Maytag Refrigerator - Instructions

Maytag Ice2-0 French Door refrigerator

Our refrigerator started slamming the icemaker door open and shut one evening. Investigation of the card behind the icemaker control panel (the LV control card) on the left-hand door revealed that the +12 volt supply that the card receives via J1 pin 3 was running at about 7 volts. As part of this investigation, I found that a wiring diagram for the fridge is in a sticky envelope behind the kickplate/grill at the bottom front of the 'fridge.

I was confused for a while because the +12 volt supply is floating, so measurements against the 'fridge frame gave very strange results. When I figured that one out, I got consistent results by measuring against J1 pin 1.

I disconnected J6 from the HV control card, located at the back of the 'fridge, and found that the +12 volt supply recovered to about 11.9 volts, so I suspected that the problem was that it was being loaded down by something. This supply gos to three places...the icemaker fan, the LV control card, and the evaporator fan (in some units)

I eventually found how to access the connector that feeds the icemaker, and disconnected it, in order to eliminate the ice fan from the supply. This made no difference, and the resistance across the supply was now 2800 ohms with J6 disconnected. I also noted that the two smoothing capacitors (C12 & C13) on the HV control card were getting hot...probably due to a high ripple current. As a load of 2800 represents a load current of only 4.3 mA, I concluded that the fault was on the HV card.

The +12 v supply is generated by an AC/DC rectifier directly off the 115 volt supply, giving a primary voltage of nearly 300 volts DC. This is chopped by a little horror of a device called a TOP247. It generates an AC waveform and drives a little transformer to generate +12 volts. This sort of circuit can be highly unstable, and it probably went into a high frequency mode, chopping at several megahertz.

Replacing the HV control card solved the problem. I have retained the card, and I intend to reverse engineer it's schematic, then try to repair it. The card cost about $150, but the actual defective component is unlikely to cost more than a few dollars, and I have a suspicion that the two electrolytic capacitors (C12 & C13) may be the cause.

First I removed the drawers above the pantry drawer. Then I took out the pantry drawer. I unsrewed 3 screws that attached the part to the refreg. I then removed the rails that were attached to the part I was repalcing and put them on the new part. I then install the new part. Put the firg back together. It was extremely easy and took about 5 minutes to do.

This repair was really easy. I first removed the water evaporator tray exposing 2 nuts and removed them with driver. Detach the dispenser faceplate and unplug the connections from the circuit board. Remove 2 more nuts holding the dispenser yoke paddle.

Remove the snap in paddle and replace with new part and spring. Complete assembly in reverse order. 10 minutes to complete repair.

First I removed the icemaker from the freezer by removing two horizontal screws holding it to the side wall, and one vertical screw holding the front to a bracket coming off the side wall. Then I used a flat screwdriver to unlock the electrical plug. (After doing this, I realized that this wasn't necessary at all, and this part could have been changed just as easily without removing the icemaker.) On the front, there is a white cover with Ice Maker Plus. Use a flat screwdriver to unlock the tangs and remove the cover. There are three screws in the corners that once removed, will allow the motor assy. to be gently pulled straight out. On the back of the part, you will see many gold lands that the timer touches. I don't think there was anything wrong with my motor. I had two spots where the gold plating was worn off, so I suspect it was not making contact, and the whole process would stop. Slide the new part in place making sure the teeth on the gears line up (not a big deal), and secure with the screws. Install cover and you're done. Mine has been making ice like it was brand new.

Took two times getting the correct part, however after getting the correct part it took about 10-minutes to replace. Had to take the fan out. When you put the new drip pan in make sure it is positioned so that the guides on the pan aligns with slots in the bottom refrig brace, otherwise back pannel will not align correctly. The fan is very easy getting aligned in the new tray. May take a little effort. I do not know why the pan on a refrighterator that is less than 5-years old could start breaking into many pieces.

After the repairman came and was going to charge me 500.00 to fix, I got on the net and found this site. Located the issue, part, and ordered it. The only trouble I had was locating the board in the fridge? It's right in the back behind the metal door, duh. Unplug each wire harness, pull board out and replace the board and plug harnesses back in. Took under 5 minutes from start to finish. It took longer to program it, after two tries I re-read the program instructions sent with the board and presto it works perfectly!!! A Big thanks to part select.com. ps if the fridge is cooling correctly you can take the top left cover off unplug the harness there and get a few days worth of cool out of it before it goes out completely but I would suggest the overnight ship if you are already dead, 24 bucks is a small price to pay to be up and running within 24 hours.

I used board levers to do one side at a time.Kinda tricky, but you can hoist up fridge high enough to replace wheels. take your time think it out and be safe . Make sure you use saftey boards to support load to protect yourself==good luck A small mirror may help to see how the rollers alien in the supports.

First, I removed the drawers at the bottom of the fridge and then I removed the three hex head (7/32) screws that hold the end cap on. Then I disengaged the slider which connects to the temperature control for the pantry drawer. Then, unscrewed the drawer slides with a Phillips from the old end cap. Also the slide push rod has to be disengaged from the clips on the back of the endcap.

Then, I reinserted the push rod to the new end cap and reattached the drawer sliders and the slider itself. At this point I realized I SHOULD have unscrewed the temperature slider at the back where it covers the cold air outlet. The screw had slipped out. I replaced it with a slightly larger wood screw. Reinstall the drawers, all done.

Removed the metal cover over the HV electronic board on the back of the unit. Using a flat head screwdriver I unsnapped the plastic cover and removed it. I unplugged the 5 or 6 cables from the electronic board. Bent back the plastic tabs holding the board. You might think they are going to break but they bend. I lifted the board out and replaced it with the new one. Then plugged the cables in being careful to align them first. I then applied power and the refrigerator came to life. I followed the programming instructions that came with the refrigerator. You can get those online also. The unit began to run and in a few minutes the compressor came on. The unit began cooling and life was good again!

Since the crisper didn't come with a front, the old front needed to be removed from the broken cripser and attached to the new one. The easiest way to take off the front is to remove it from the bottom of the crisper. Once the pressure is released it comes off easy. Snap the front on the new crisper by starting with the top and snapping the bottom.

Ordered a new Dispenser Front Overlay, removed the housing from the refrigerator, unplugged the old Overlay and pealed it off, applied the new Overlay (taking care to line it up correctly), plugged in the new Overlay and reinstalled the housing. Works great!

I pulled the whole unit(condenser&overload relay)
with my hand & disconnected the wire connected
to it & Replaced it with the new one.Peace of cake.

First, I removed the Climate control drawers, the lower shelf pieces and the Chef's Pantry drawer so I had room to work.

Next, I unfastened the two screws that held the pantry drawer gilder on the broken righthand end cap and removed the glider.

With a socket tool, I unfastened the three socket-head mounting screws that held the endcap to the refrigerator wall.

The righthand endcap has a climate control adjustment mechanism which includes a finger slider and an extenson bar snapped to the backside of the endcap. This extension bar connects with another bar mounted to back inside of the refrigerator.

I carefully disconnected the climate control mechanism fixed to the refrigerator from the endcap.

With the endcap out of the refrigerator, I next had to disconnect the climate control slide and extension bar from the broken endcap by unclipping several snaps holding these pieces in place.

Now with the new endcap, I clipped the extension bar in place, snapped the finger silder in place, and reconnected this assembly to the climate control bar in the refrigerator and clipped the mechanism to the rear of the endcap.

The socket mounting screws were used to fasten the endcap to the wall. The pantry drawer glider was attached to the endcap with it's screws. The shelves and climate control drawers were put back. Finally, I carefully snapped the Pantry door to the hinge pins on both the left and the (new) right end caps and put the pantry drawer back.

changed the starter connected to the compressor

Turned the old one to unseat and replaced with a new one in the reverse order.
