Troubleshooting Samsung Flex Tray Ice Makers
Wes Sirois
Assistant Manager, HA Product Support
Troubleshooting a No Ice Condition

All Troubleshooting should begin with verification that the freezer temperature is low enough for ice to be produced.
A freezer should maintain a temperature at or below 1°F for proper cooling and ice making.

Verify with the customer that the unit has been on for 24 hours and the freezer is cooling properly. The freezer temperature should be 1°F or less, which you can check by pressing the “Fridge temp” button. The display will show the
fridge section “set” temperature on the right and the “actual” Freezer temperature on the left. On models with a bar
graph display, the Freezer display (on the left of the display panel) should show the lowest bar only.

Check the icemaker sensor at the Main PCB. The Main PCB supplies constant DC voltage to the sensor. At 1°F,
the voltage should be approximately 3.7 VDC. To check the resistance of the sensor, remove the sensor harness
from the Main PCB and check resistance. At 1°F, the sensor should read approximately 28K Ωs.

Verify that your readings are correct by checking the actual temperature of the ice maker sensor, which is attached
to the underside of the ice tray, directly under the last cube.
Test Button
Sensor

Find the temperature on the conversion chart below. If the resistance and voltage readings you took are correct for
the temperature reading, the Ice Maker sensor and wiring are good. For example, if the voltage reading was 3.45
VDC, the temperature at the sensor should be ~10.5°F and the resistance of the sensor should be ~22K Ωs. A 10%
variation is acceptable.

If the voltage and resistance are not correct based on the temperature, the sensor is bad and the Ice Maker must be
replaced.

Symptom – The ice maker does not fill or partially fills

To check the fill mode, you will need to initiate a harvest cycle manually by pressing the Ice Maker test button and
holding it for 5-10 seconds. Once the harvest cycle begins, it will take approximately 5 minutes for the Ice Maker to
complete. Watch for the proper up and down movement of the ice sensing lever during this test harvest.

After harvest, the Ice Maker should take in water, filling each cube opening. If the water level is correct, the water
components are working properly. If the level is low or there is no water, check for air in the system. Models with a
water dispenser usually include a reservoir, which should be filled completely with water and no air. Check the water
lines, water valve, fill tube and water filter, making sure all connections are air tight. If water fill is still too low, remove the water and try filling again with the filter removed. The filter may be clogged and need to be replaced.

continued

If no water enters the Ice Maker, initiate a harvest cycle and check for 120 VAC to the fill valve at the appropriate
time. If 120 VAC is present, replace the water valve. If no 120 VAC is supplied, suspect the Main PCB or a loose
harness connection.
Slow Ice Complaint

Always use the minimum expectation of ice production for a 24 hour period as a guideline when evaluating a slow
ice complaint.

The ice maker should average at least 12 harvests in a 24 hour period, yielding approximately 84 to 108 cubes. Under optimal conditions, the harvest mode should occur every 60 to 90 minutes. However, when you take into account
defrost cycles, usage, and ambient conditions such as temperature or humidity, the refrigerator is likely not performing under optimal conditions and ice production could suffer. Also, keep in mind that the Ice Maker will be turned off
by the sensing lever when the bucket is full.

New Spin Cycle Program for 300 Series Washers
Louis Picchione
Manager, HA Product Support
The spin program on the 300 series washers (WF330, WF331, and WF350) has been revised. With the new program,
the unit will try 4 times to reach maximum RPMs. If, after 4 tries, the unit cannot reach maximum RPMs, it will finish the
spin cycle at 500 RPMs. In most cases, the clothes will still be fairly wet.
Troubleshooting
If the washer fails to spin properly, the most common customer complaint is either “Low RPMs” or “Clothes still wet
after spin cycle”. To remedy these complaints, first check to see if the unit needs to be leveled. If it does not, then
check if the customer overloaded the unit.
Note: In the illustrations below, the new Wi-Fi model (WF457) was used to illustrate the new spin cycle program better.
If the unit is experiencing
any kind of spin issues, it
will count down to 6 ~ 7 minutes and hold there.
The unit will now tumble the clothes
for 1 minute and finish the cycle.
Page 5
If, after 4 tries, the unit
doesn’t achieve maximum
RPMs, it will resume
counting down the cycle
while spinning at 500
RPMs.
After 4 minutes, the unit
will now automatically drop
down to 1 minute.
The cycle is now completed, but
due to a spin issue, the unit never
went over 500 RPMs, leaving the
clothes wet.

Manager, HA Product Support
RESTRICTED AIR FLOW
GOOD AIR FLOW
If the venting system or lint screen housing is clogged, it will cause a restriction in the air flow.
With a gas dryer, a restriction in the air flow will cause the flame to flair out. If the flame flairs out,
it will make contact with the Hi-Limit, causing it to open and shut down the heater. As long as the
restriction remains, the thermostat will continue to shut down the heater. This will prevent the
dryer from ever achieving maximum temperature and drying clothes properly.
