Re: Samsung RS21 problems – need an error code deciphered…

Hi Vince,
The first error code you have means that the ref section is taking longer than 80 minutes to complete a defrost. This will indicte a fault with either the Thermal fuse, defrost heater or the defrost sensor in the ref section. Your new error code is the ice maker sensor, this can be repaced as a complete ice maker unit. If you switch the ice maker off on the control panel this error code should disappear.

Re: Samsung SR S2029css side by side ref/f

There is a problem with the defrost cycle, probably a Thermal fuse blown or defrost NTC sensor. The Thermal fuse should have a circuit through it and the resistance will change as the temperature of the defrost sensor changes (warmer temp lower resistance value)

Re: samsung sr-s2029cvw

Hi Phil
Is the unit in a cold environment? If so this may help.

Under the top left side hinge cover you will find an ambient sensor, this stops/delays the condensor fan if the ambient temp is cold usually below 13 degrees

Re: SAMSUNG RS21DCSV1/XEU recurring fault or not fixed?

Hi Dave

If you call out an eng ensure all the defrost components are checked if all is ok next step would be the evap cover.

The refrigerator evaporator cover has been modified with a larger vent/drain hole just below the fan to ensure any defrost water is removed, the fan has also been improved with better shaft seals to prevent moisture ingress.

Re: 134a pressures

I have always found with a cold cabinet R134a will be 0 – 2″Hg.

Re: Samsung Side by Side Refrigerator problem

Samsung give a 2 year warranty, if the fixing loop has snapped completely then a new door is required. Find that receipt!

Re: Samsung SR-S20

When the engineer returns get him to test the thermal fuse, it is located on the right hand side of the evaporator (red/black wires). You should get a circuit when testing for continuity, if open circuit also test the evaporator heater.

Re: SAMSUNG RS21DCSV1/XEU recurring fault or not fixed?

I have experience of Samsung appliances and it seems that a lot of engineers assume that any defrost cycle fault must be the PCB. If ice is building up on either evaporator (side by side models) it is usually caused by either the Thermal fuse (open circuit), defrost NTC termination sensor (yellow wires) out of calibration or a faulty defrost heater.

One of the most common symptoms of a defrost cycle componet failure is that the appliance works for 6 – 8 hours and then stops working, the temp displayed will be -20 & +3 but food will spoil in the freezer. If the appliance is unplugged and reconnected it will run fine for 6-8 hours.

The reason for this is the temp display always shows an average temp, during the defrost cycle the temp shown will be the average temp prior to defrost.

If the defrost heater or thermal fuse is faulty no heat will be generated during the defrost cycle and so the defrost termination sensor is waiting for the temp of the evaporator to rise, so the unit sits waiting for the temp to rise, if the door is not opened this will take hours.

If the appliance is disconnected from the mains the PCB will reset and work fine until the next scheduled defrost cycle.
