Samsung RFG238AARS/XXA

 

My brother is having some construction work done at his house.  The contractor has flipped the breaker a few times as they wire in new circuits.  The fridge has a surge protector on it, but apparently didn't protect it from this.  Now the panel is completely unresponsive, is flashing a code, and will not dispense ice or water.  It still seems to be cooling.

Thanks in advance for your help

Thanks.  Based on the Samsung secret handshake of holding the Energy saver and Lighting buttons down for 8 seconds, the display is back to normal.  Do I still need to order the PCB?  What about the Cool Select Zone Sensor?  According to the error codes, that is the fault that pattern was showing.  I looked at all the sensors on Repair Clinic - none shared that name.  Which one is secretly known as the Cool Select Zone Sensor?  There was a Fixer Sensor.  Does that detect an oncoming appliance repair person so it can behave while the repairman is there?

no, the flashing segment is on the "ten's digit"

Couldn't see the forest for the trees...  I was concentrating on where the dash was disappearing and overlooked it was on the wrong digit.

 

Is the PCB board accessed from the rear of the unit?  Is it the inverter board - http://www.repaircli...mber=RFG238AARS

 

It appears this replaces an older model number.  Seems weird on a refrigerator that was manufactured just over a year ago.  Are these failing so fast the board had to be redesigned?

Update time.  My brother let me know he bought the extended warranty.  So - he called Lowes, the sent out their "certified repairman" and he pushed the energy saver and lighting button for eight seconds (taking it out of test mode) and said, "Problem solved..."  Yeah, right.

 

So, two months later his little magic trick of skipping out of test mode doesn't work - the display is now locked on the flashing 8s screen.  This time I called for my brother.  Spoke directly to the tech's wife (found out they run their shop out of their garage - husband and wife tag team.  Found out he didn't have access to the tech sheets, so I read them what Samsung said to do when that part of the digit was flashing.  He ordered the main PCB board and installed it two days ago.  No joy - still flashing the same digit as before.

 

He called a buddy and he told him the flashing light meant the heater element was bad.  So, he said he would order one and try that.  I'm not sure how they arrived at that, unless he didn't correctly communicate which segment was flashing.  Anyone have any real ideas?  Thanks.

Two things to keep in mind regarding samsung fridges
1) their mainboards rarely ever fail... I have yet to experience a bad one.

2) Any malfunctioning thermistor can shut down the fridge.

On the older Samsungs If you have any error code a power outage will shut the refrigerator down. This is most likely why it worked for a while after the error was cleared.
As Durham posted samsung main boards rarely fail.

btw, that code is a freezer defrost error...error code 12. Reg was correct in stating it was on the tens digit but it is the tens digit on the fresh food, not the freezer. Your system shut down due to a failed heater, freezer evap thermistor or bimetal.

yeah, not sure why he ordered a heater without checking the thermistor and bimetal. My guess he will replace them all once he's there to hedge his bet.

I've had a few Samsungs flash defrost or maybe it was defrost sensor codes a few times. Installed the defrost sensor and it fixed it. It's very easy to ohm the heater and fuse or bimetal. Actually the one I had flash a defrost sensor code had a weak wire that broke as soon as I touched it. And of course one of my former coworkers came out before me and reset it then left like it was good to go.

... Reg was correct in stating it was on the tens digit but it is the tens digit on the fresh food, not the freezer.

... Your system shut down due to a failed heater, freezer evap thermistor or bimetal.

I see that now,

but that segment on the Fridge 10's digit wasn't shown for any model RFG's

but is shown for (2) other models

 

CF Compartment defrosting heater-open or short-circuit, connector failure,
or defective temperature fuse/bi-metal. Defrost on for over 80 minutes

Error occurs and is displayed when regarding the CF compartment defrosting heater,
there is an electric wire cut, short-circuit, contact failure, sensor housing missing, or defective temperature fuse.
A defect is displayed if defrosting is not finished after continuous heating for more than 70 min, for the CF compartment.

I'm not entirely convinced this guy could find the bi-metal or thermistor, but we'll give him the benefit of the doubt.  I will make sure and post when he gets the part ordered (1-2 weeks...) and gets it in.  Thanks for all the input.

Well I know you couldn't just order the heater on most Samsungs when I was working, but that was 6 months ago. Typically we ordered the evaporator assembly and had to remove the swaps the heaters that way. If they did get the whole assembly they it may come with a new bimetaland sensor.

When under warranty the whole evap is replaced. Out of warranty you can just do the heater if available by itself. Very tricky from what I have read.

Yea, we just unwound the heater from both evaps and installed the the new one without changing the evap. It looks confusing though because the heaters look the same as the coil. I ordered a couple, but never got my own call back to change it.

Well - he may be chasing the wrong bird here - he told my brother it was the heater that kept the water line from freezing....  Unfortunately, they failed to call to let us know when they were coming so I didn't get to be there.  All of this was third person over the phone...

it's possible a failed drainage line heater can cause a defrost issue... but.... but.... oh, never mind.
