Got a 2 year old Kitchenaid KRMF706ESS01 that keeps resetting every 5-10 minutes with the code PO on the screen. I've researched the issue and replaced the main control board, power board and the user interface. None of which fixed the issue, can anyone offer any insight as to why my $3,000 refrigerator is no longer working?

......keeps resetting every 5-10 minutes with the code PO on the screen.

Does everything shut off when it resets (lights, compressor, fans)

Everything shuts off, upon disassembling my entire freezer I learned the drain tube was frozen. Which in turn caused ice to build up and burn the evaporator fan motor up and cause the evaporator fan in the refrigerator part to not get proper air flow. Thawed the drain tube, thawed both sets of coils and all is well. New fan motor is on the way! This has been a long journey to get to this point!

That wouldn't cause the machine to shut off. Keep an eye on it.

I'm having the same exact issues.
Everything I've been reading everywhere points to the evaporator fan motor.
@MatthewVick, which of the evaporator part did you replace? was it the RC evaporator fan motor or the FC evaporator fan motor?

I've been at this for 4 days now. I've replaced the Mainboard, did not fix my issue. I've replaced the power supply board too, did not fix the issue.
Majorly everyone I've read from, on here and other appliance forums points, says the evaporator fan motor was what fixed their issue.
It's what I want to try next.

so which should I get? The freezer fan motor or the the refrigerator's? And what is the part #?

NOTE: It's a kitchenaid KRMF706ESS01
I have some cooling in the refrigerator part but absolutely no cooling from the freezer.
No lights inside both compartments.

Thanks yall.

I too am in the same boat. I’m very happy that I found a similar thread to this one, and the user suggested going through the service tests to see which one causes a reset.

I’m curious, did you replace both fans? Or did you choose one and get lucky?

Thanks!

I am in the same boat as well. Most threads say to replace the main board. I'm not really interested in risking $350 on a fridge like this. It is too expensive to have these type of problems and I don't want to risk 10% of the purchase price to *try* something.

The evaporator fan motor thought makes sense.... Better than "just replace the board". So, I'm curious if anybody has done this and how that worked?

FIXED - WRV986FDEM01 Whirlpool: Too warm & frequent restart w/ PO error

A few months back, our freezer and refrigerator started slowly warming up. It was barely noticeable at first but eventually got worse much faster resulting in a complete defrost and the refrigerator getting to what seemed like room temperature (slightly colder, but not cold enough!). After the...
