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 5.2.1 and recheck.
5.2.4

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.
draws are:
The Yellow lead = 5.8 amps.
The Orange lead = 15 amps.
Total current = 20.8 amps.
Note: The current draw will decrease as the elements
get hot.
5.2.5

Check the Gas Valve/Regulator (Gas Only)

5.2.5.1 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 5.2.5.2.
5.2.5.2 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 5.2.6.
