Model Number

KRMF706ESS01

Brand

KitchenAid

Age

1-5 years

this morning noticed no control panel lights, no interior lights, no ice/water function. Do not hear condenser running at all. Temp started climbing. Did several long power off resets at breaker. no startup chime or control panel functions. Checked drawer(Pantry UI) for condensation on circuit board - none. Tore down freezer and found evap fan was starting/stopping every 1 to 1.5 seconds. Lots of ice on coils. completely thawed it out and plugged back in. No change. No clicking at control board on back either. Unplugged all Aurora board plugs, no change. Next steps i should try?

side note, we've gotten several PF or PO error codes over the last few weeks. We've never gotten those in previous 3 years. Not sure if related.

update on clicking noise that i've seen in other posts. On main board(back of fridge) i do hear a very faint clicking but it's in sequence with the freezer evaporator fan starting/stopping. Not sure if that helps or not. Also, Pantry UI circuit board is still unplugged.

Unplug the freezer fan motor and see if the PO stop coming on and the clicking stops.

Thanks Jake. I unplugged it and yes now i have power to front panel and can get into diagnostic mode. Fan in frdge section is running. However lights, ice maker, water dispenser do not work. Is that because freezer fan is unplugged or do i have more issues?

Were they working before you unplugged that freezer fan motor?

The only thing that worked before unplugging the freezer fan motor was the freezer fan motor. No cooling fridge or freezer, no control panel, no lights, no fridge fan, no ice or water.

Once i unplugged freezer fan, then control panel lit up and i can get into diagnostic but water ice dispenser dont work, frig fan started, interior lights still off.

I have new fan ordered. Be here tomorrow. Was wondering if i also have main circuit board issues too or all those other things not working related to freezer fan being unplugged?

Lets wait till you get the new freezer fan installed.

Possibly its the control board too. These particular boards have had some issues as well.

Make sure you unplug the refrigerator from the wall outlet before you replace the control board.

Here's the control board for your model, if needed:

Replacing fan didnt help. I replaced control board and everything working as it should now. Thanks for your help.

Glad to hear the new control board fixed it.

Thanks for the update!
