MBL1957FEZ01 Maytag Refrigerator - Instructions

I replaced the control board first. The freezer back panel frosted up and the refrigerator warmed up again. Then I force (short option vs long) defrosted the refrigerator. However, a few days later the defrost issue came back again. Force defrost no longer worked, though likely due to a severe ice build up behind the freezer panel. I ordered the wire harness. I took off the freezer door (loosen four screws only), removed the tray rails, ice maker, thermostat housing and vent mounted on the freezer panel. The rails and the vent are a bit tricky to remove since no directions exist. I then removed the fan above the coils and then removed the wire harness. Installing the new harness is easy except that I had to modify one of the ground connections for it to mount properly. I tested the unit for 72 hours. The defrost cycle eventually kicked in (dripping onto a pan and sizzling sound). I then reinstalled all parts. No frost build up. Good to go!

The digital display numbers (0= off and 7=coldest setting) controlled by the ECB would continually be replaced by straight lines, and the refrigerator would stop cooling. I tried unplugging it for a while. After plugging it in again, it worked (the digital display came on, I set it to "4" and it reached the proper temp), but the problem occurred again the following day, and then it stopped cooling entirely. I ordered the ECB, and it arrived in 3 business days. I watched the installation instruction video, took my time, double-checked the vid a few times to make sure I was doing it correctly, and replaced the ECB by myself in less than an hour. The refrigerator has been running without problems for 3 weeks now. My fridge had a different light bulb configuration than the one in the video, but everything else was the same, and it was a simple repair.

(1) Slide out appliance and remove power source. (2) Removed lower access cover on rear of refrigerator. (3) Disconnected plug to the condenser fan motor. (4) remove blades by pulling gently forward (5) remove mounting hardware holding the fan motor (3 screws) (6) motor is now free and new motor can be installed

Used a screw driver to pull old switch. Pulled one wire at a time, only two wires. After wires instlled to new switch push new one back in place where the old one was.

Followed the video and installed the new Jazz board. The board cam in 1 piece which had to be separated into two pieces, but the scored area on the board made it less intimidating. At the same time I replaced the two incandescent lamps in the refrigerator area with LED lamps. Getting the housing for the control board apart was the most difficult part, installing the replacement board was a breeze.

I simply removed the old switch using 2 small screwdrivers and the old switch case popped out. I then upluged the wires from the old switch and reversed the process. Didn't take longer than 5 minutes begining to end! Thank you for the great service! Duncan quaid

Remove rail and removed broken black plastic spring mechanism with new one and then replace rail.

Replaced the rail and slide baskets. Also readjusted the basket. This was extremely easy and saved me close to $500

Removed the 2 screws holding the light bulb shield, then the 4 uolding the metal panel. Unplugged the olw door switch and replaced.
reassembled the pieces.

Ordered new fan motor
Got part took fridge apart
Result was the motor was running
The fan blade had come off the motor
Replaced the motor anyway and reinstalled the fan, working well

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.

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

I initially tested the heating element and defrost thermostat using an ohm meter. the defrost thermostat was incased in ice, so I replaced it first. The refridgerator worked for about a week and then froze up again. I then replaced the thermistor and the unit is working as designed.

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