ABB2224BRB01 Maytag Refrigerator - Instructions

Having seen this problem before in other equipment so I had an idea where to look. Problem: the automatic defrost function was not operating. Looking through openings in the back panel of the freezer compartment, you could see the evaporator coils and fins were a solid chuck of ice. There are three logical components to check. Heater element, thermostat (located just above the evaporator) and a relay on the control board (located in the fridge control panel). Checked the heater with an ohm meter -- OK. The thermostat closes the circuit at around 20 degrees and opens at around 32 degrees. Pulled out the thermostat, wiring, fan unit. Everything unplugs, unscrews, and unclips, don't cut wires. Put the whole assembly in a friends freezer for an hour or so to see if the thermostat closes -- OK. Problem had to be with the control board. Replaced control board, reprogrammed it per included instruction. Everything is working again.

A very easy fix took all of five minutes

The hard part for me was figuring out which part was causing the problem. I read what others had done and followed their test methods. I checked the defroster heater for continuity and the defroster thermostat to make sure it was closing. the defroster termostat has to be cold to check it. You will need to check it while it is in ice or take it out and put it in another freezer for 30 mins and then check it for continuity. Those items checked out ok so it had to be the control board. The control board is a 5 min job to replace but making sure that is your problem is the hard part. I think the control board was bad due to a power surge we had when the power went out and came back on. It might be a good idea to put a surge protector on your home to protect your fridge and all your other electronic stuff. Our refrigerator is now working like new again. Thank you for all your help, Jim

First thing to do is take two screws off where the door closes.I removed the light sheild off by pushing it to back of refrig.The most hardest part is removing the complete panel,I took a small flat blade scraper to ply down to get small access than you need to put alot of pressure to start getting the panel to start coming off there are alot of pegs to free,the back panel has two hinges that slide towards the front.Once the panel drops remove the connectors and take entire unit out,very easy to replace the control board at this point.Installation is easy slide the two hinges on back in place and put pressure on unit to snap entire unit in place.Program unit with paperwork that came with part very easy to do.Frig is working great now.Just a note the paperwork on refrig is located in the front right corner the mf hids it ,this information will allow you to check all problems with refrig using the key pads for freezer/refrig.Good luck.

The video on website is very good and explains everything in detail. Just follow the directions. This is EASY!!!!

I used a flat-head screwdriver to pop out the old light rocker switch. Then, I unplugged the wires, plugged them into the new light rocker switch, and then popped the new switch into the hole. That's it! Lights began working again.

removed ice maker and wire shelf. removed back panel screws and tilted forward. removed 2 screws holding motor bracket. swapped fan blade and reassembled

replaced control board

I used a flat screwdriver and released the lock tab on the bottom of the light switch, and pried the switch out, being careful to not damage the plastic around the mounting place of the switch, unplugged wiring from old switch, plugged in the new one and pushed the new switch into place. Job finished light switch now working.

removed old rail,lifted glass panel above and inserted new rail-voila!!done.

An easy job for smaller hands. Removed the two bolts holding the light cover. Removed two electrical connections from the old switch by pinching the retaining clip,removed the switch, snapped in the new one and re-attached the connectors. Your online illustrations helped me to know that the plastic housing for the light switch would only swing down so far and was not intended to be removed. Saved me from breaking that plastic cover's tabs. This home repair saved me more than 5 times the cost of hiring a professional to do it. Very happy homeowner.

Once I saw the replacement part I understood how to pry out the switch with a small screwdriver. Then just unplug the old one, plug in the new one and pop it into place.

The PartSelect site made it easy to correctly identify the correct part, it was inexpensive, and the shipping was fast.

I'm very pleased!

Removed screws from cover tested for power to motor found power was on to motor but motor did not work. I went to your web site was able to locate part in about 5 minutes . Even with over night shipping the part came to about $50,00, far cheaper tha a service call would have been.

Thanks John Paulsell

Remove the light cover. Use a flat head screw driver to push in the tabs on the back of the program mount and pull down to expose the computer board. The Thermistor is clipped on under the vent holes on the right side. Cut both wires to remove the old thermistor strip a 1/4 inch off the remaning wires and the new thermistor wires twist both ends together crimp on the wire caps snap in the new thermistor reinstall the program board until the retainer clips snap into place, slide the light cover back on.

Unplugged and empty refrigerator, completely defrosted refrigerator using a hair dryer to speed up the defrosting, put a lot of towels on the floor to soak up the water when the ice melts. Removed all refrigerator racks and drawers, then remove the white plastic and styrofoam condenser cover. You will then see the thermistor, cut the two small wires connecting the thermistor to the harness leave yourself as mush wire as possible. Splice in the new thermistor and put the refrigerator back together.
