Check The Motor Windings; Problem - Under Drying/Damp; Possible User Faults; Possible Installation Faults - Fisher & Paykel smartload DEGX1 Service Manual

5.3.3

Check the Motor Windings.

(a) Remove the cover of the motor control module. (Refer to Section6.35)
(b) Unplug the motor harness from the motor control module.
(c) Check the resistance of the motor windings at the plug end of the motor
harness. Resistance should be 9.6 ohms across any two terminals of the plug.
(d) If the motor resistances are correct, replace the motor control module.

Problem - Under Drying/Damp

5.4.1

Possible User Faults

(a) Ensure that the customer has chosen the correct cycle for the type of clothes
being dried.
(b) Ensure that the customer has chosen the correct spin speed on the washing
machine. If the clothes are spun at a slow spin speed, they will be wetter and
will therefore take longer to dry.
5.4.2

Possible Installation Faults

(a) Is the cabinet externally vented? If vented into the room, the damp air is being
recirculated through the dryer and will increase drying times.
(b) Is the venting configuration within those specified in the installation instructions?
Excessive length or number of bends will restrict the airflow and decrease
drying performance.
5.4.3

Possible Maintenance Problems

(a) Is all venting clear of lint, kinks, etc? Lint build up or kinks within the venting
system will restrict the airflow and decrease drying performance. Check the
inlet grill, burner inlet grill, venting and vent outlet grill/shutters to ensure that
they are clear.
(b) Has the lint bucket been emptied?
(c) Are the lint filter and exhaust sensor free of lint?
5.4.4

Check the Inlet and Outlet Duct Seals

A leak in either the inlet duct seal or the outlet duct seal can cause the hot air to
bypass the clothes load in the drum.
5.4.5

Check the Heating Circuits

(a) Check the thermostats. (Refer to Section 5.2.1)
(b) Electric models, check the elements. (Refer to Section 5.2.2).
(c) Gas models, check the igniter, valve and flame detector. (Refer to Sections
5.2.5, 5.2.6 and 5.2.7.
5.4.6

Check the Moisture Sensing Circuit

(a) Check that the machine is correctly earthed.
(b) Check that the conductivity contacts are connected correctly.
(c) With the power disconnected from the dryer, use a suitable high impedance meter on
a high ohms range to measure the resistance between the conductivity contacts. It
should be 6.4 megohms (+1 megohm). Between either contact and the drum it
should be 4.3 megohms (+1 megohm).
(d) Check that the conductivity contacts circuit is registering the dryness levels of the
clothes. (Refer to Section 4.3.1.2)
