Hi Guys,
First, I'd like to thanks the Admins, Techs and Contributors to this forum for all the help your posts have provided in the past!
We purchased our KRMF706ESS01 (s/n K730xxxx) Fridge in late-2017 after Hurricane Harvey claimed virtually all of our household appliances.
Since then, it has proved to be both the most expensive AND most unreliable appliance we have ever purchased - we are already on our third RC Evap Fan (with sensors), our second icemaker, our second two-way water distribution valve, our second Pantry UI Board and our second Condenser Fan.
The current issue is best illustrated by the attached photo - The FC is being driven far below the user-selected temperature of +5°F, while the RC fails to get close to the selected temperature of 33°F.
This suggests (to my aging brain, at least) that the issue may be caused by either:
A: Incorrect measurement of the current temperature in the FC,
or, (less likely, I feel)
B: Communication failure between the door-mounted UI board and the main controller board, whereby the main controller board is not receiving the user-selected temperatures from the UI board.
- Although there are probably other scenarios that could cause the same symptoms...
I have two Main Controller Boards (from previous experiences), and get exactly the same results with both.
Both FC and RC Thermistors show a pass (01) on Service Tests 1 and 2 respectively, but I've yet to find a test that shows the actual temperatures that the MC board thinks that are current (I gather from other posts that some KitchenAid models do have this feature). I may be missing something here...
I do have one question - Thus far, I haven't had to delve into the FC control hardware, so I'm unsure where the FC temperature-sensing thermistor is located - Does it come with the FC Evap Fan assembly, along with the defrost thermistor, like the the RC Evap Fan?
Any suggestions as to the root cause of this issue would be most welcome - I'm reluctant to add to my collection of KitchenAid parts by trying to shotgun this issue - The parts are so overpriced.
Thanks, and Best Regards,
Pedro.
