MBF1958FEZ05 Whirlpool Refrigerator - Instructions

My son (who does HVAC, but not appliance repair) did some investigating by taking front and back panels off and determined that the evaporator coil was freezing over because the defrost wire was not heating up. He and his girlfriend did some real-time internet searching for diagnostic info because NO control diagram was included with the refrigerator. He determined the problem was most likely the electronic control board. Ordered and installed a new board and the refrigerator is back to working fine. Took about 2 hours to diagnose the problem and 1/4 hour to actually install the control board. Kind of disappointing that this control board failed when the refrigerator was less that 4 years old.

I first removed the bottom shelf. Then I popped the rail in. It was pretty easy although I did have to use some force to fit it in. Ordering the part and doing it myself was a lot cheaper than calling the repair man.

Loosen the top 2 screws, remove the bottom screw, unplug the wire harness, lift up the ice maker and remove. To install the new one simply reverse the removal procedure.
Note: You may want to wipe the inside of the new one to remove the protective grease or discard the first 2 cycles of ice.

Watched video. Unplugged refrigerator and popped out switch. In plugged connector and pushed switch in place. Plugged in refrigerator and the light worked

Took out the drawer and upper rack out of freezer removed back wall from freezer took out fan motor housing and replaced motor and thermostat. Works like new now.

just pop the old one out popped the new one in its replace.

Let the ice in the freezer melt while installing P trap drain tube

Referencing the info/schematics you have on your website, I unscrewed/unattached top-front panel (carefully), from behind the panel you have to detach the wires (2) from the switch, pushed "in" the switch to remove, put in new switch and attach wires to test BEFORE remounting panel. Tada!! Thank you PartSelect! You saved me at least $80...would have been at least $100 to have a repair person come to the house!

Snapped in new part

Total time 10 minutes. 9 minutes to clear out the food and 1 minute to install the part. Installation was self evident and could have been done blindfolded. Part just snapped in.

Popped off the control panel at the top behind the door. Found the thermistor and replaced it, cutting the wires and splicing the new one in. Immediately the warm section of the refrigerator was getting below freezing temperature readings, so the cooling vent was not opening. I put the old one back on and the temperature readings went back to being accurate. So this was not the problem. I believe now that the fan somehow is not blowing enough cold air up. So now I'll probably buy a fan motor and maybe a blade and try that. Otherwise the computer module I priced at $500 so I hope it isn't that. I replace the fan motor a few years ago already.

Talking with the service tech and youtube video it was a snap... Saved a service repair and a 25% parts mark up..

Repair went well,took about five to ten minutes to disconnect the power from the fridge removed the defective switch installed the new one ,reconnected the power,,,and Let there be light and there was light!

removed the freezer door, removed the two shelves and removed three screws from the icemaker, unplugged the wiring harnest. Installed the new icemaker in reverse procedure.

Popped out with butter knife and unplugged 3 prong connector and reversed with anew switch.

But, unfortunately it got broken again exactly same way as before.
So, I ordered same switch again for 2nd time.

Maytag should recall that Rocker Switch and build with better materials.
