Model Code Confirmation – Just a reminder that it is important to always confirm the exact model code when working
on Samsung products. This is because
we have many models with a similar
model name prefix but a different model
code. Consequently, the corresponding
parts may be different. Also remember to
not use the Service Manual to research
part numbers as these are not updated
after initial production. Instead, use the
Exploded View, Quick Parts, or one of the
other research tools available on GSPN
to research the part. If all else fails, contact GPCA directly and one of our staff will
gladly assist you to determine the correct
part number to order.
GPCA Goes Green – As part of Samsung’s
overall commitment to environmental responsibility, the Rancho Dominguez, CA
facility recently replaced all of its lighting
fixtures with high efficiency lamps and ballasts. We expect this change will reduce our
electrical consumption by half. This is the
latest step in GPCA’s efforts to reduce our
impact on the environment. Earlier green
projects have included advanced part recycling and reclamation efforts and the usage
of environmentally friendly shipping and
packaging materials. In the upcoming
months, advanced solar panels will be installed on GPCA’s roof along with a new,
high efficiency heating/air conditioning system. These projects along with many other
employee-led efforts will make the Rancho
Dominguez facility one of the most energy
efficient buildings in the area.
Part Research Update – As you may have
noticed, there have been some issues with
the Part Research tools on GSPN since
Samsung transitioned to its new computer
system. Rest assured our engineers are
working day and night to restore the functionality so that it is better than ever. In the
meantime, if you need Part Research assistance, please feel free to submit a Research Inquiry on GSPN or call GPCA at
(800) 634-8276 Mon-Fri 7:00 am to 4:00 pm
PST.

It’s easy to become complacent or even judgmental
about a customer’s problem. “What’s the big deal, they
probably have two other TVs in the house” or “It’s only
an icemaker – they can survive without ice for a day or
two”. We need to be careful not to judge the customers
motivations. We can be empathetic to their situation
and possibly win a customer for life.
A servicer told me a story about a customer that had a
problem with their ice maker. While he diagnosed the
problem, the customer was moving around the house
frantically, dusting, cleaning, and picking up. He told
the customer he had to order a part and would return in
a few days. The customer was beside herself when she
got the news – she was hosting a small cocktail party
that evening for her husband’s co-workers and the
NEW Boss! The servicer apologized for the inconvenience, got in his van, drove two blocks to the corner
store and returned with two bags of ice. All the customer could say was WOW!
The servicer didn’t have to go out of his way. It cost him
two dollars and a few minutes of his time, but he won a
customer for life. You can bet his customer will tell that
story any time the topic of good service comes up or
when a family member, friend, or neighbor needs service. Small investment, BIG returns.
While you can’t be expected to carry bags of ice or a
spare TV in your service van, you can look for ways to
“WOW” the customer. A follow up call to make sure the
repair was successful, a discount on future service, a
thank you call for a referral…anything to make YOUR
customer feel special and your service memorable. The
“little things” DO count.
Zone 3 (NC, SC, GA)
This is an exciting time of change here at Samsung.
We have changed our system to make it more centric,
Page 2
changed the locator to improve call management, and
as most of you have heard, have moved our call center
to South Carolina. The migration of the call center is
not complete, so both call centers are still running in
unison. When speaking with someone at the call center, make sure that you get the name of the person you
are speaking with. This will assist your RSE should
there be a need to contact that person. For example,
the call center rep told you the company was extending
the customer’s warranty and the RSE needs to contact
the rep to confirm the extension.
We appreciate your understanding and patience as we
make these changes and strive to be the best in all that
we do. In the end, the payoff will be great for everyone:
customer, servicer, and Samsung.
Call Trackers Relocated
The Eastern Zone has moved all of its call trackers to
the Greenville, SC facility. These trackers are there to
assist in long term pending tickets and as a resource
for you to use when they contact you. The Central
Zone will be moving their trackers to the facility next,
and then the West will follow to wind up the migration of
all of the trackers.
Servicer News
Samsung has begun to launch an FE and ME (Master
Engineer) center in many markets with the goal of getting 50 MEs on line by the end of the year. The MEs
will be located in high call volume areas and will deliver
a higher level of service to our customers. They will
begin to change the perception of service centers as
they win customers over with their exceptional service
and hospitality.

with the practice and begin using it in your daily customer contact.
Zone 6 (MN, WI,IA,IL,MO,AR, OK)
One of the main reasons claims are rejected is the lack
of a bill of sale. Warranty will pay a claim without the bill
of sale if the date of manufacture is within 14 months of
the warranty call. If you haven’t received information at
a Samsung training session on how to determine the
date of manufacture using serial numbers, you can see
this in the policy guide on GSPN. Your RSE can also
get this information for you.
When you run a call, it is best to ALWAYS ask the customer for a copy of their bill of sale, and to keep a copy
of it for your records if at all possible. Do NOT take the
dispatch warranty information for granted. This is only
what the customer has told the Samsung call center
associate and may not be accurate. Get a copy of the
proof of purchase information to make sure the call is
covered under warranty, and to keep your records up to
date for any possible future calls.

Issue: Sheets get tangled during dry cycle.
Design overview: Drum Tumblers are designed to roll the clothes as the drum turns to allow maximum air movement
and ensure consistent drying. Drums are much larger in the Ultra Capacity models, creating the potential for tangling to
occur.
Cause: Because of the larger drums in the Ultra Capacity models, it is possible for sheets and similar bedding items to
get stretched out along the outer perimeter. As the drum turns, it is also rolling the sheets, causing the bedding to become tangled.
Resolution: Recommend the consumer use the Time Dry cycle and add a few towels to the load to prevent tangling.

Issue: Left side refrigerator door will not stay open.
Cause: Dispenser wire harness and waterline are foamed into the door liner and fed through the upper door hinge.
When the product is new, the harness may be stiff, causing it to pull slightly on the door when it is open.
Resolution: Customer Education. This is normal, and other factors may contribute such as food load in the door and the
leveling of the unit and doors. Only make leveling adjustments if needed, not to correct this problem. Normal use will
loosen the harness and correct the problem.

troubleshooting inverter compressors
Jim Swift
Manager—RTSC
Steve Polzin
Tech Support Specialist
Samsung has introduced a number of refrigerators in the past year which incorporate an inverter type compressor. The
inverter compressor design saves energy by allowing the compressor to run at variable speeds. A standard compressor
turns on and runs at full speed until the temperature drops to the required value. Power consumption is higher because
of the constant starting and stopping. By comparison, the inverter compressor speeds up and slows down to maintain
the temperature. The compressor runs longer but at a slower speed, saving energy. This new design creates some
challenges for troubleshooting.
ISSUE: Compressor Does Not Run
TROUBLESHOOTING: First, bypass the door switches and confirm the fan motors are running. If any of the fans are
running, the main PCB is calling for cooling and the Inverter PCB should be receiving the signal to run the compressor. If
the fans are off and the compartment is warm, this indicates the Main PCB incorrectly thinks the compartment is cold
enough. A sensor, the sensor wiring, or the main PCB could be the problem. Verify the sensor and wiring by measuring
the sensor voltage at the main PCB. A normal sensor should measure between 1 and 4 volts depending on the temperature of the compartment
If you determine the sensor and board are operating properly, follow the steps below to test the inverter and compressor.
1. Access the Inverter PCB located directly
above Main PCB on back of unit (this is in
the compressor compartment on RSG
models). 2. Check the status of the red LED. 3. If there is no LED operation, check the
fuse. 4.
If the fuse is good and 120VAC is present
between the Red and GRY wires, replace
the Main PCB.
5. If the LED is on or flashing, the Main PCB
is probably working. All the remaining test
procedures can be done from the Inverter
PCB. Count the number of LED flashes
and compare to the chart on the next page. Page 10

Issue: The compressor is running, but the compartment is warm.
Note: This scenario assumes there is no sealed system leak or restriction. Use standard sealed system troubleshooting
to test this process.
Troubleshooting: Access forced operation mode to verify the compressor speed changes properly. As you cycle
through the FF1 (High Speed), FF2 (Medium Speed), and FF3 (Low Speed), wait 5 seconds between modes and listen
for the compressor speed changes. You can also measure the current draw in each mode to verify the proper operation.
If the speed does not change, there is probably a bad transistor.
Solution: Replace the inverter PCB.

evaluating sensor cycle drying complaints
Steve Polzin
Tech Support Specialist
Ultra Capacity Models such as the DV448 have a large 7.4 cubic foot drum. The large size of the drum can lead to customer confusion or complaints when customers use the Sensor Dry Cycles. You can often resolve these complaints by
providing customers with a clear understanding of the Sensor Dry Feature and proper Customer Education. Common
complaints include;
•
The clothes are wet when the cycle completes.
•
The dryer shuts off too soon.
•
The dryer runs for 5 minutes, and then shuts off.
These complaints are often the result of loads that are too small or
loads that contain a mix of unlike materials such as Permanent Press
shirts and towels, jeans and sheets, etc.
How Does Sensor Dry Work?
Sensor Dry automatically measures the moisture in the load when wet
clothes move across the moisture sensing bars located in the front of
drum. During Sensor Dry, times are determined by moisture levels detected in the clothing and by the size of the load. The time that is displayed at start up is a pre-estimated time. In the first 3 minutes of operation, the Samsung Dryer makes an initial measurement of moisture.
As a result, the actual drying time can increase, decrease, or stay the
same. The dryer makes further measurements throughout the cycle
and automatically adjusts the time as needed including advancing to
Off when no moisture is detected. For Sensor Dry to work properly, it is
important the load is large enough so that clothing consistently makes
contact across the two moisture sensor bars located in the front of the
drum.
Customer Education Points
•
Explain to customers that they should fill Sensor Dry loads to a minimum of 60 to 70% of the drum’s capacity to
ensure proper operation. For smaller loads, customers should select Time Dry.
•
Point out that they should confirm they have selected the desired dryness level (from very dry to damp dry) .
•
Explain that, for best results, they should always dry like items together — towels with towels, jeans with jeans etc.
This ensures consistent and accurate dryness levels.
•
Provide a simple explanation of how the moisture sensing feature operates.
•
Remind the customer that the DV448 has an ultra large capacity drum.
You can find complete troubleshooting procedures for all models in the Service and Training Manuals found on the
GSPN Web Site. Don’t forget to check out the extensive library of Service Tips and the recently added Video Tech Tips.
