WRB322DMBW02 Whirlpool 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!

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.

Just snapped in new shelf

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.

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.

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

We snapped the new one on correctly this time.

Removed the shelf, attached new glide, and replaced shelf

I did not unplug the refrigerator. Your choice on this. Take a close look at the existing icemaker, how the wires are routed and what the water spout looks like as it relates to the icemaker. Small flat-blade screwdriver will help in unlocking tabs on the icemaker plug. Go ahead and unplug it. Of the three screws that secure the icemaker, two are impossible to see without holding a mirror in your third hand. Completely remove the bottom screw (by feel). Don't drop it, like I did. Have no idea where it went. Loosen the top two screws but do not remove. Icemaker will lift off of the top two screws when you push it up. With old icemaker out of the way, plug in the new icemaker. Be careful to properly align the water spout into the new icemaker as you hook it on the two top screws. When everything looks good, tighten the two top screws. Replace the bottom screw, if you didn't lose it. My icemaker is doing fine without a bottom screw. It should make some ice within an hour, or so. Mine did.

Hardest part is access to the icemaker itself. Once I removed the freezer door (bottom drawer freezer), and got the sliding basket out, it was a 10 minute job. Make sure you start the upper screws first, the icemaker will hang there while you adjust, connect the harness, and tighten. Make sure you are ready before you close the door, it will start making ice as soon as the door is closed.

Used a deep well 1/4" nut driver. Loosen 4 screws on inside of door and slip it up and off rack. Remove 2 screws on bottom of ice maker. Loosen top 2. Slip up of screws, unplug ice maker and remove.

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.

I first replaced the lower (freezer) evaporator thermistor based on recommendation from other feedback, however that did nothing to resolve the problem. I subsequently discovered a diagnostic document hidden under the upper right door hinge, which helped me narrow the problem down to the upper (refrigerator) evaporator fan motor. After replacing the fan motor, my refrigerator is up and running again. The only challenge was accessing and removing the access panel(s) and air column. Once those were removed, replacing the fan motor was simple.

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

Removed the door and replaced the broken door closure bushing. I had courteous help and responce from Parts Select people. Excelent turn around time on parts delivery.
