My KitchenAid KRMF606ESS01 ice maker is working very inconsistently and doesn’t make a lot of ice. I also get ice melting in the bin and leaking inside the fridge. I ran several diagnostics and cannot seem to find a problem but I do get error E05 on test 56. Thermistor test showed a pass and all other related ice maker functions seem to be fine. Seal between ice maker and door also seems ok.

I'm attaching the tech. data sheet below.

Service Test - 56 Ice Maker Error Codes
--->Displays active Ice Maker Error Codes on the UI display. (E0 = No Errors, E1 = No Cooling, E2 = Motor Lost Position, E3 = Heater Timeout, E4 = Dry Cycle, E5 = Timed Ice Making).

E5 = Timed ice making. This code indicates the ice maker thermistor is warmer than 16° and the ice bin thermistor has been below 45° for 3 hours. An E5 can be the result of a defective IM thermistor, bin thermistor, loose thermistor connection, ice box fan not running or a cooling issue.

Put a freezer thermometer inside your freezer and tell us what it reads after 2 hours.

Do you hear the ice box fan running?

Hi Jake

I placed a thermometer in the back of the middle drawer of the freezer and it read around 9 F after 2 hours. A quick note that I lowered the freezer set point down to -5 F a while ago when I first noticed problems with the ice maker but it didn’t seem to help. I am not sure if the freezer temp should match the step point exactly?

I did check all the thermistors shown on the tech sheet (1, 2, 32, 37, 39, 58, 65, 77) and they reported a 01 - PASS. The humidity read 28 which seems low if that is the ambient but I am not sure where it is read.

I can’t really distinguish the ice box fan from a sound perspective but I did force it on and off in diagnostic mode. It appears the fan is running based on feel of airflow. I tried to measure the airflow but the velocity was too low for my anemometer to detect it.

Thanks

Mike

Your freezer is too warm, its need to be closer to 0 degrees F.

You are possibly at the beginnings of a sealed system problem, you will need to contact KitchenAid Canada and have their tech. come out to investigate this.

You should have a full 5 year warranty on your sealed system parts and labor.
