Before testing any of the components, perform
the following checks:
• The most common cause for control failure is
corrosion on connectors. Therefore, discon-
necting and reconnecting wires will be nec-
essary throughout test procedures.
• All tests/checks should be made with a VOM
or DVM having a sensitivity of 20,000 ohms-
per-volt DC, or greater.
COMPONENT TESTING
• Check all connections before replacing com-
ponents, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
Refer to page 4-1 for the procedure for servic-
ing the timer.
1. Disconnect the power to the ironing sta-
tion.
2. Disconnect the timer motor connector from
terminal 2 of the timer.

3. Set the ohmmeter to the R x 1K scale.
4. Touch one ohmmeter lead to the timer
motor wire terminal, and the other lead to
one of the white AC wires. The meter
should indicate between 2000 and 2400
Ω
.
5. Set the ohmmeter to the R x 1 scale.
6. Set the timer to 0 (off).
7. Touch the ohmmeter leads to timer termi-
nals 1 and 3. The meter should indicate an
open (infinite) circuit.
8. Turn the timer knob to the 1 position.
9. Touch the ohmmeter leads to timer termi-
nals 1 and 3. The meter should indicate a
closed (0
Ω
) circuit.
