4. On model 24-CGA-10 carefully disconnect leads WH/ORG and
WH/PINK, WH/BLU from the pre-heat thermal switch. Tape the ends of
all leads to avoid shocks and short circuits during testing.
5. On model 24-CEA-10 carefully disconnect leads PUR and BLK, BLU
from the pre-heat thermal switch. Tape the ends of all leads to avoid
shocks and short circuits during testing.
6. Adjust the ohmmeter for a zero reading on lowest scale.
7. Refer to Figures 6-19 and 6-20, and connect the ohmmeter leads across
the preheat thermal switch. When the steam generator has cooled, check
the ohmmeter reading.
• If the meter reads infinite ohms across pre-heat thermal switch terminals,
replace the thermal switch.
• If the meter reads 0 ohms across pre-heat thermal switch terminals,
continue this procedure with step 8.
8. Set the ON/OFF switch to the ON position. Watch the meter reading as
the SteamCraft 10 heats up and generates steam. When the unit starts
generating steam, check the meter reading.
• If the meter reads 0 ohms across the switch terminals, replace the pre-heat
thermal switch.
NOTE: Model 24-CEA-10 units may steam for one or two minutes
before the switch opens.
• If the meter reads high or infinite resistance, the pre-heat thermal switch
is good. Perform steps a through c below and end the procedure here.
a. Set the ON/OFF switch to the OFF position.
b. Disconnect the ohmmeter leads from the thermal switch terminals.
c. Connect the respective switch leads to the pre-heat thermal switch
terminals and replace the right side service panel.
In the following procedure, replace the notation 115/120 VAC with the correct
operating voltage for the SteamCraft 10 model being serviced.
• The correct operating voltage for 24-CEA-10 models is 120 VAC
• The correct operating voltage for 24-CGA-10 models is 115 VAC.
1. Set the voltmeter to the 250 VAC scale.
2. Set the TIMED/MANUAL switch to the TIMED position.
3. Set the ON/OFF switch to the ON position. Zero and clear the timer.
4. Refer to
Figures 6-21 and 6-22.

• If the meter does not read 115/120 VAC between these
TIMED/MANUAL and ON/OFF switch wire connections, replace the
TIMED/MANUAL switch.
