GENERAL INFORMATION
General Theory of Operation
Heat Pump Technology
A typical dryer uses large amounts of energy; this dryer
consumes a fracon of the energy by recycling and reclaiming
heat. This dryer is a ventless heat pump dryer that uses a
refrigeraon system to dry and recycle the same air. The
laundry is dried with low temperatures; therefore it may feel
cooler than expected during and aer the drying process.
The heat pump dryer’s heang phase is longer than in
tradional dryers. If possible, do not open the dryer door
during the process as heat can escape from the drum and can
make longer drying mes.
Benefits of a Heat Pump
• ENERGY: Regenerates energy to reduce overall energy
consumpon.
• PERFORMANCE: Allows exibility to manage drying
performance and energy savings.
• FABRIC CARE: Capability to use less heat than vented dryer.
• VENTLESS DESIGN: Allows installaon in more locaons
throughout the home.
New Sounds from a Heat Pump
• Dryer runs on a compressor like your refrigerator and you
may noce a hum from the compressor.
• The water from wet clothes is pumped out to your drain.
You may noce a gurgling sound occasionally.
Heat Pump Dryer Heating System
Sealed System Theory of Operation:
Mechanical heat pumps exploit the physical properes of a volale evaporang and condensing uid known as a refrigerant. The
heat pump compresses the refrigerant to make it hoer on the side to be warmed, and releases the pressure at the side where
heat is absorbed. Refer to the diagram below for the following operaons:
1. The refrigerant (R134a), in its gaseous state, is pressurized (heated) and circulated through the sealed system by the
compressor.
2. The now hot and highly pressurized gas is sent to the condenser secon of the heat exchanger unl it condenses into a high
pressure, moderate temperature liquid. The condenser heats up the process air which will be sent to the drum.
3. The condensed refrigerant then connues to the post condenser―with the help of the auxiliary fan―begins the cooling of
the refrigerant.
4. The refrigerant then passes through a pressure-lowering device such as an expansion valve, or in this applicaon, a capillary
tube further decreasing the temperature of the refrigerant.
5. The low pressure liquid refrigerant then enters the evaporator secon of the heat exchanger, in which the uid absorbs
heat, boils and is converted to a gas. This is accomplished when the fan blows the hot process air (from the drum) across the
evaporator, which also helps to remove moisture from the humid process air. The refrigerant then returns to the compressor
and the cycle is repeated.

General Theory of Operation (continued)
Heat Pump Dryer New Components
Post Condenser Fan – used for cooling the refrigerant in the post condenser. The fan is connected to J2 on the ACU.
Drain Pump – to drain water in the sump collected from the evaporator. The drain pump is connected to J3 on the ACU.
Water Level Switch – checks the water level in the sump. If the tank is full, the switch will be open. If the tank is empty, the
switch will be closed. The water level switch is connected to J8 on the ACU.
HX Filter Switch – is a magnec reed switch that signals the ACU when the Heat Exchanger Lint Filter is not installed. The dryer
will not operate if the Heat Exchanger Filter is not detected. The lter switch is connected to J8 on the ACU.
Whirlpool Heat Pump Compact Dryer Block Diagram
The Heat Pump Compact Dryer is not unlike its predecessor—the Whirlpool Hybrid Heat Pump Dryer. Most of the components
used in the Whirlpool Hybrid Dryer are also used in the new Heat Pump Compact Dryer. Think of the compressor as the heater.

DIAGNOSTIC GUIDE
Before servicing, check the following:
nMake sure there is power at the wall outlet.
nHas a household fuse blown or circuit breaker tripped? Was
a regular fuse used? Inform customer that a me-delay
fuse is required.
nMake sure the dryer fan, lint screen, and secondary lint
lter are clear of lint and obstrucons.
nAll tests/checks should be made with a VOM (volt-
ohm-milliammeter) or DVM (digital-voltmeter) having a
sensivity of 20,000 Ω per volt DC or greater.
nResistance checks must be made with dryer unplugged or
power disconnected.
nVoltage checks must be made with all connectors aached
to the boards.
nIMPORTANT: Avoid using large diameter probes when
checking harness connectors as the probes may damage
the connectors upon inseron.
nCheck all harnesses and connecons before replacing
components. Look for connectors not fully seated, broken
or loose wires and terminals, pin inseron, or wires not
pressed into connectors far enough to engage metal barbs.
nA potenal cause of a control not funconing is corrosion
or contaminaon on connecons. Use an ohmmeter to
check for connuity across suspected connecons.
SERVICE DIAGNOSTIC MODE/
SERVICE TEST CYCLE
Allows service personnel to run the Service Test Cycle to verify
inputs to the dryer and funconality of the dryer control. You
may want to do a quick and overall checkup of the dryer with
this test before going to specic troubleshoong tests.
ACTIVATING SERVICE DIAGNOSTIC
MODE
IMPORTANT: Use Service Diagnosc Mode without laundry in
the dryer.
See the chart on page 5 for a summary of the steps in the
Service Test Cycle.
To enter Service Diagnosc Mode:
1. Be sure the dryer is in standby mode (plugged in with all
indicators o).
2. Open and close the dryer door. The door must be closed to
enter Service Diagnosc Mode.
3. Press and hold POWER unl the dryer display turns on with
indicators scrolling from le to right. When the me remaining
display turns on, within a few seconds:
4. Press and hold DELAY START and OPTIONS unl display
shows “FC” (the dryer will count down “3-2-1” before
displaying “FC”). Turn the cycle selector knob one click to the
right unl display shows “SC” for Service Test Cycle. Rotang
the cycle selector knob will toggle the display between “SC”
(Service Test Cycle) and “FC” (Factory Test Cycle).
DO NOT SELECT OR RUN “FC” (FACTORY TEST CYCLE), AS IT
IS FOR FACTORY TEST PURPOSES ONLY AND REQUIRES THE
FACTORY ENVIRONMENT AND TEST EQUIPMENT. The START
LED will be ashing slowly. Immediately press START. The
control will beep and the display will show “S00”.

Checks the lint/Heat Exchanger (HX) lter status. Press START
to go to next step.
S01
Press START again; the display will go blank for less than one
second and then the boom row icon LEDs will ash. Press
each boom row icon from le to right and corresponding
LEDs on the control panel will light and go out accompanied by
a beep. Turn the cycle selector knob to the le one click at a
me. The seven segment display will light up one segment at a
me corresponding to the turning of the knob. Now, turn the
cycle selector knob to the right unl the outside of the seven
segment display has lit up, then press the cycle selector knob.
Press START to go to the next step.
S02
Checks the motor status; this roune starts the motor
movement in a clockwise direcon. Press START to go to next
step.
S03
Checks the motor status, but in a counterclockwise direcon.
Also turns on the drain pump. Press START to go to next step.
S04
Checks the oat switch, moisture sensor, and drain pump. The
oat switch and pump are veried by performing a manual ll:
remove the top panel and the water tank, add water directly
to the black water tank cavity of the dryer unl the water tank
icon turns on and the pump acvates. Put the water tank back
into place; the water added to the back hole will now ll the
container. Aer container is lled, wait 60 seconds for the icon
and the pump to turn o.
The humidity (moisture) sensor check is achieved by resistance
value: See Test #5: Moisture Sensor, page 18.
Press START to go to next step.
S05
Veries the status of the compressor by monitoring the
temperature: if the temperature increases at the condenser
NTC (thermistor) in a specic period of me and the display
shows, for example, “t24”, “t25”, etc., then the compressor is
OK. If not, “F23” will be displayed. Press START to go to the
next step.
S06
Veries post condenser fan funconality. Press START to go to
next step.
S07
The last error code detected by the dryer will be displayed.
Press START to exit Service Test Cycle.
Activation with Saved Fault Codes
If there is a saved fault code, the F number will be shown in
the display. Only one acve fault code can be displayed. If
no fault codes are stored, the display shows “S07” and “F00”
alternately. Review the Fault/Error Codes beginning on page 6
for the recommended procedure.
Unsuccessful Activation
If entry into Service Diagnosc Mode is unsuccessful, refer to
the following indicaons and acons:
Indicaon 1: None of the indicators or display turn on.
Acon: Make sure AC power is available to the dryer.
Indicaon 2: Display is on, but unable to enter Service
Diagnosc Mode.
Acon: Press and hold POWER unl “3-2-1” and then “rES”
appears in the display. Turn o the dryer display. Wait 10
seconds. Turn on the dryer display. Follow the Acvang
Service Diagnosc Mode instrucons on page 3.
