The tech. data sheet I posted in post #4 above tells you how to get into diagnostics, if it won't go into diagnostics, then that control board is the culprit.
Hello Jake, thank you for the reply.
I've noticed you suggested this fix to a few users, and so did other techs on other websites, but the customers never seem to be able to access the diagnostic mode after the install of the new control board with the revision 2.
This is the only post I've found that had someone with the same model as me and being able to access diagnostic mode.
I should probably start my own thread, but here's my problem...
I started to have food freeze in the fresh food section (refrigerator) a week or two ago, so I turned down the temperature control in the ff section but the problem kept occurring.
What I did next was changing the control in the freezer to minimum (Max, Recommended, Minimum) but I should have had it on the Minimum setting instead to send more air into freezer.
The reason I was doing that at first is because I thought cold air from the freezer was freezing my food in the ff section...
I also found my manual and it said not to leave it on Max or Minimum for too long, which I didn't know...
Anyway, like 3-4 days later I noticed my food stopped freezing in the fridge but my food in the freezer also started to melt...
So unsure what's going on, I raise the coldness setting from the fridge section (it control the entire unit) but my freezer never got any colder.
2-3 more days, past and my food at the front of the freezer is almost all melted and my meat is starting to thaw in the back...
I put all my foods in coolers and put them outside (winter temp) and start taking apart the unit.
First, the coils were kinda dirty so I gave them a good clean with a small brush and an air compressor.
Then, I started inspecting the bottom of the unit (with the coils) and found a small oxidation on the frelon tube going into the compressor (I think it's that). It' a small drip of green oxidation, not sure if that's a leak or something leftover from installation? Also, the compressor was really hot and before unplugging the fridge, I noticed the fan in the freezer was not running and a lot of hot air was coming from the vents.
Anyway, I also opened the top unit (freezer) evaporator fan cover (the plastic one) and found a block of ice had formed over the coils and the tubing in the top right section.
I wish I could describe it better, but it looks like the second image in the photo I attached, as in, only part of the coil were frozen with clear ice and it only seems to have affected one side of the coils (they were bent slightly, the fins).
I unplugged my fridge for 4-6 hours, waiting for the ice to melt and replugged. Waited 12+ hours, added water icepacks and some frozen foods to the freezer and place a thermometer in there.
After 4-6 hours, I checked on the icepacks.. none were freezing. I checked on my frozen foods and it was thawing, I checked the thermometer and it had only reach 0.2C. That was using recommended setting for both the fridge and the freezer settings. So I tried making the fridge colder and turned the coldness to 4 Snowflakes (almost max setting) and the freezer after a few hours was only at -0.3C and peaked at -4C.... obviously something is wrong and it should have been colder. Yesterday I unplugged the fridge again for 24 hours, and just replugged it. I will test the temperatures again tomorrow but I fear the unit is defective.
I don't know what else I can do, I don't have alot of knowledge when it comes to appliances...
I'm not even sure if it's still on warranty, my manual only mention 1 year limited warranty, but I've seen on the TV that a fridge should have a warranty of 5-10 years.
Do you know how I can know about my warranty? Should I contact Whirlpool and ask them to do the repair or contact a local technician ?
I also found 2 services pointers for this model... #W10849156 and #W10902061
One refers to the control board, and the other one to a piece of foam gasket.
Do you think the second one is worth investigating if that unit has been running fine for 3-4 years ?
I disassembled the evaporator plastic cover, but when I tried, I was unable to take apart/remove the styrofoam.
