My serial number is HR92847408. Can you post a copy of the bulletin?

Thanks,

JSS

Was your serial number before the one posted on the bulletin?

 

[caralann]

Got the evap cover and insulation/fan housing off. It was socked in.

Once defrosted will recheck fan voltage, fan operation, ohm out thermistor again.

How did you get the insulation cover off? Mine does not seem to budge. thanks

Check for any air leaks within the air duct, and evaporator cover assembly. If the evaporator cover is difficult to reassemble, this may indicate that airflow parts are not properly aligned and not sealing properly. Verify Proper door alignment.

Check your serial number for a service flash (#HR60100001-#HR85200001). Check the evap fan motor for proper operation. When the ref section is calling for cooling, the control checks the evaporator for a set temperature. If it's below the set temperature the control turns the fan on for several minutes to make sure the coils are defrosted completely before starting a cooling cycle.

Same problem -- my serial number HR65... falls in the range. How do I get a copy of the service flash. I have one that says prior to HRX40 which I do not understand. Thanks.

Rick has been out sick since Jan.12th with a serious illness, we are hoping and praying for a speedy recovery!

I attached that service bulletin in post #41.

Did anyone figure out how to fix this and what the culprit is? I have the same fridge an issue. Is this something with the bulletin that Kitchenaid will fix for you?

Also following to see if this has been resolved, having same issues with model KRSC503EBS01

Were you able to fix yours?

I replaced the thermostat in the refrigerator and completely defrosted the entire unit for a week and so far for two months no issues at all.

Oh wow good to hear, I just ordered the evap fan assembly and a new thermistor. Hoping that does it

You mean the evaporator thermistor? This one:
Temperature Sensor W10316760

Here’s what mine looks like. When people are talking about “air leaks” are they talking around air getting around the edges of this styrofoam piece, or around the plastic that goes over/around it it?

FIXED - Kitchenaid fridge KRSC503ESS01 fridge side evaporator coil freeze and frosted monthly

Hi, I have buggy fridge, where the fresh food evaporator will frost up when ever there is too much moisture and the fan stop running. It happens once a while (every 6 months), but much more frequently recently. I think parts are all working after I defrost manually. Can someone suggest what I...

That's what I don't know, I've not run across issue myself as of yet.

Yes that is the one

Thanks @ewhitenight for letting us know.

Same with mine. More frequent now. maybe 2-3 weeks. Did you get a fix?
I'm not sure if I've broken a rule but I turn off CB, remove the Styrofoam & fan and defrost with a hair dryer which takes about 20-25 min when totally frozen. Then the last two times I have left it as in your photo & just defrosted the visible fins. Takes about 5-10 min and still lasts 2-3 weeks. I have remote reading thermometers that graph the temp over time and the RC drops to 29 initially then back in the 37 range. I don't recall the temp dropping so low when I defrosed the entire evaporator. I suspect the thermistor is still frozen when I do it this way but not sure why the lower RC temps as opposed to thawing the entire evaporator.

So what I did to fix mine and boy it’s worked now is I unplugged and manually defrosted for 2-3 days. During that time I replaced the thermistor part listed above then when I plugged back in I went into the service tech settings and changed auto defrost to manual which then has the fridge defrost every 6 hours which has now fixed the issue. No more frost at all.
