Product Information

Specifications

• Model: 234D2703P003
• Revision: 4
• Nomenclature: T- = Timer Control, M- = Drive Motor

Description

The product is a dryer used for drying clothes. It operates
using a drive motor and a timer control. The dryer has various
components, including ganged centrifugal switch, main motor
contacts, and a junction by connector and terminal. It is designed
to provide proper air flow for normal operation of the temperature
control and safety systems.

Air Flow and Seals

Proper air flow through the dryer is essential for normal
operation. The air is pulled into the cabinet from the rear and
drawn up across the heaters located behind the drum. From there, it
is pulled through the drum rear, across the clothes load, through
the lint trap, and down the trap duct into the blower. Finally, the
air is pushed out of the exhaust system. Any air leaks between the
air inlet and the blower can result in improper temperatures and
reduced air volume across the heaters.

Trap Duct Sealing

To ensure proper sealing, inspect the trap duct by removing the
lint filter and looking down into the duct. Examine the trap duct
on all sides where it meets the dryer front for any voids in
sealing. Any leaks can be sealed with permagum.

Drive Belt

The drum of the dryer is rotated counterclockwise at a speed of
47-51 RPM. The belt tension is maintained by a spring-loaded idler
pulley and driven by a pulley attached to the rear motor shaft.

Service Parts and Lubrication

For long vent models, follow the steps below:

1. Grasp the pulley and force it to the left 1 to 2.
2. Hook the pulley shaft on the bracket idler arm, ensuring that
   the cap nut assembly is behind the bracket.

Wiring Diagram

The wiring diagram is located on the back of the access
panel.

Product Usage Instructions

Air Flow and Seals

To ensure proper air flow and sealing:

1. Make sure there are no air leaks between the air inlet and the

2. Inspect the trap duct for any voids in sealing and seal them
   with permagum if necessary.

Drive Belt

To maintain the drive belt:

1. Ensure that the drum rotates counterclockwise at a speed of
   47-51 RPM.

2. Check the belt tension and adjust it if necessary using the
   spring-loaded idler pulley.

Service Parts and Lubrication

If you have a long vent model:

1. To remove the belt, grasp the pulley and force it to the left 1
   to 2.

2. Hook the pulley shaft on the bracket idler arm, making sure the
   cap nut assembly is behind the bracket.

AIR FLOW AND SEALS Proper air flow through the dryer

Inlet Air

is essential for normal operation of

the temperature control and safety

systems. Air is PULLED into the

cabinet from rear and drawn up

across the heaters located behind

the drum. This hot air is PULLED

through the drum rear, across the

clothes load, through the lint trap

and down the trap duct into the

blower. From the blower the air is

PUSHED out of the exhaust system.

Any air leaks between the air inlet

and the blower, such as lower drum

front left or trap duct to cabinet front sealing, will result in improper temperatures. The air being pulled

Exhaust Air

Heater

down the trap duct to the drum outlet thermostat will be cooler than

normal, giving this thermostat a false indication (delayed or no-trip).

Leaks ahead of the blower will also reduce the volume of air across

the heaters causing hot spots and possible premature failure.

TRAP DUCT SEALING
To inspect the trap duct for proper sealing, remove the lint filter and look down into the duct. With a light examine the trap duct on all sides where it meets the dryer front for voids in sealing. Leaks may be sealed with permagum.
· WHEN FLEXIBLE DUCT IS USED. WE STRONGLY RECOMMEND METALLIC FLEXIBLE DUCT.
· EXHAUST DUCT MUST BE 100mm (4 INCH) DIAMETER
· FOR SPECIFIC EXHAUST SPECIFICATION, REFER TO INSTALLATION INSTRUCTIONS SUPPLIED WITH THE DRYER.

DRIVE BELT
The drum is rotated counterclockwise, as viewed from the front, at a speed of 47-51 RPM. Belt tension is maintained by a spring-loaded idler pulley and driven by a pulley attached to the rear motor shaft.

5 To Remove Drum:
Service procedure: After removing the front panel, move the idler pulley to the bracket motor to lock it, so you can loosen the belt. Once belt is loosened and moved off the motor pulley, slightly lift and pull out the drum.
Reassemble note: Re-route the belt on the motor and idler pulley, then release the idler from the motor bracket. Be sure that the belt is correctly routed on the idler pulley and motor pulley. Slowly turn the drum by hand counter- clockwise to ensure belt is aligned and not twisted. Drum RPM should be between 45-55 after re-assembly of the front panel. Verify that the slides on the top bearing are in the correct position.

WASHER FIELD SERVICE MODE
ENTRY OF FIELD SERVICE MODE: Control must be in idle/standby state (all leds off). Press and hold Start button, turn the cycle knob 180 degrees and then release Start button. Once service mode is entered, all LEDs will blink. Rotate knob clockwise to various positions per service function table to perform funtional checks. When a load is tested, it is necessary turn the program knob to another position, to turn off the load.
EXIT OF FIELD SERVICE MODE: Field service mode will time out after 30 minutes if there is no user activity. Press and hold Start button for 3 seconds or unplug power to the machine. When exiting field service mode and going back to standby the previous cycle state may not be restored.
Once the washer is in service mode, the following service features are available via the cycle knob (on some models):

Spin

Pressing Start will start the test.

Spin test will perform child safety algorithm before it starts to spin. (Two (2)

sprays of water before locking the lid.)

The lid must be closed to start the test. If lid is open the Lid Locked LED will

blink. When started, the mode shift to spin will occur if required and the lid

will be locked. When mode shift is complete, the unit will begin spinning.

Spin test will have a timeout (4 minutes).

No OOB detection during the spin.

The spin shall stop when the test is exited.

The lid shall unlock once the speed reaches 0 after the test is exited.

14

Agitate Pressing Start will start the test.

Agitate test will perform child safety algorithm before it starts to agitate.

The lid must be closed to start the test. If lid is open, the Lid Locked LED will blink.

When started, the mode shift to agitate will occur if required.

When mode shift is complete, the unit will begin agitating.

The test will pause if the lid is opened after starting.

The test will resume on lid close if it was running when opened.

The test will stop when the test is exited.

Analog Knob Pressing Start will start the test.

Each knob is represented by a specific status LED.

When knob position changes, LED for the specific knob indicates knob position.

The far left selection will turn the corresponding LED on solid.

With each click to the right, the LED for the specific knob blinks faster.

Clicking back to the left will reduce the blink frequency until it gets to the far

left selection, then the LED will stay on solid.

The left option knob will control the deep rinse LED (`On’ LED).

The right option knob will control the wash rinse LED (`Wash ‘ LED).
