There's something going on with these dual evap units, and Whirlpool is aware of it. Per Service Pointer W10666205A dtd March 2014:
Slow Ice/No Ice
Warmer than normal freezer temperature
Long/Constant run time
Partial frost pattern on the freezer evaporator
discoloration or deterioration of the refrigerator evaporator housing
Note: The first symptom a customer notices is usually a decrease in ice production followed by a noticeable temperature increase in freezer and longer than normal cooling cycles.
1. Verify the above symptoms with customer.
2. Check and record freezer, refrigerator and ice box temperatures.
3. Run tech sheet diagnostic test #4 (Compressor/Condenser fan/Evaporator fan) and #56 (I/M error codes) and record the results. Call the Techline (Authorized Servicers Only) from the customers home for further instructions.
Affected Serial Numbers: K217XXX - K335XXX
And Brother CubbieBear84 reports this:
We have scraped 3 of these fridges already. I've heard there's holes in the evap. Tech-line will record all the data and if it fits within their set criteria they give a concession number and send a new one.
Something to keep in mind if you're called out on one of these with a warm compartment complaint.

The first day I replaced a bad mainboard and replaced the evap thermistor for good measure. There were no burned out fan resistors and the evap fan seemed to work fine. Rookie mistake. I still should have tested the fan's rpm at the board. Heck, I should have just changed out the fan regardless just to protect the new board as GE suggests. But I was trying to save my customer some money. My punishment? A second visit and second disassembly.
This makes two times I had to do a follow up disassembly of this style. A year ago I did a defrost on a similar model but already used up all of my thermistors earlier that day. What joy. At least when doing a follow up dissasembly, the overly factory tightened screws have been loosened up.
bring the whole family as this disassembly and reassembly is lots of fun for everyone. However, you better bring ear plugs for the kids for the curses you'll throw at the fridge designers will be legendary.
- 2 tablespoons coconut oil, ghee, or butter
- 1 onion, chopped
- 1-2 pounds uncooked chicken breast, diced
- 1 inch piece of fresh ginger, peeled and chopped fine
- 4 cloves garlic, minced, divided
- 1 quart chicken broth (I use either homemade or a box of low sodium, no added MSG.)
- 1 can coconut milk (look for this in the Asian/Thai section of the grocery store. I prefer regular, not "lite".)
- 1 lime, juiced, divided
- ¼ tsp. red pepper flakes
- 4 scallions, chopped
- ½ bunch cilantro, chopped
- salt, to taste
- optional: Thai fish sauce, cooked rice
Heat a soup pot over medium high heat, then add the coconut oil. Saute the onions with a little salt for a few minutes, then add the chicken chunks with a little more salt. Cook, stirring frequently, until chicken is just cooked through. Add the ginger and half of the garlic towards the end of this.
Stir in the broth and bring to a boil, then stir in the coconut milk, half of the lime juice, and the red pepper flakes. Reduce the heat to low and simmer covered for at least 15 minutes (longer is fine, too).
Turn off the heat, and add salt to taste (depends on the amount in your chicken broth). Stir in the rest of the garlic, the scallions, and most of the cilantro (leave a little aside for topping individual bowls). Add the rest of the lime juice if desired. Cover and let sit off-heat for 5 to 10 minutes, then serve.
Great served over rice. Add a few drops of fish sauce to your serving to knock the flavor out of the park!
[Yes, I did reset the breaker and checked the voltages. Here's the wiring diagram:
