Check Voltage Across Elements (Electric Only)

WARNING: Because the power must be on to carry out the following checks extreme care
must be taken as death or electrical shock can occur.
(a) Refit the top deck and reconnect the machine to power supply. Start the dryer (Note: If
there is no wet load in the dryer, the controller will turn the heat off after a short space of
time.)
(b) With the dryer running on a regular cycle in the closing direction, and with the drum up to
speed, use a voltmeter and measure the voltage of the 1.4kw element, between the violet
wire on the front element connection and the violet wire on the mains relay on the motor
control module. The voltage should be equal to mains voltage of approximately 240V AC.
Measure the voltage of the 3.6kw element between the yellow wire on the front element
connection and the yellow wire on the relay on the motor control module. The voltage
should be equal to mains voltage of approximately 240V AC.
(c) If there is no voltage, replace the motor control module and retest the dryer. If there is
voltage, go back to Section 6.2.1 and recheck.
6.2.4

Measure the Current Draw for Each Element (Electric Only)

This is an alternative to measuring the voltage.
(a) With a clamp amp meter, measure the current draw
of each element. Approximate current draws are:
The Yellow lead
The Violet lead
Total current
Note: The current draw will decrease as the elements get
hot.
6.2.5

Check the Gas Valve/Regulator (Gas Only)

6.2.5.1

Primary Coil

(a) Disconnect the primary valve connector and
measure the resistance between terminals 1 and 2.
Resistance should be 1.4 kOhms.
(b) Measure the resistance between terminals 1 and 3.
Resistance should be 560 ohms.
(c) If the resistance is incorrect, replace the
valve/regulator. If the resistance is correct, go to
Section 6.2.5.2.
6.2.5.2

Secondary Coil

(a) Disconnect the secondary valve connector and
measure the resistance between terminals 4 and 5.
Resistance should be 1.3 kOhms.
(b) If the resistance is incorrect, replace the valve/regulator. If the resistance is correct, go to
Section 6.2.6.
