BURNER OPERATION
ISSUE POSSIBLE CAUSE SOLUTION
Ironing Cylinder Heats to SET
Temperature, but Will Not
Ignite a Second Time
1. High temperature limit con-
trol has tripped.
• Allow ironing cylinder to cool down and
then manually reset high limit control.
2. Ignition electrode wire is
loose or broken or gap is
incorrect.
• Refer to Pilot Ignition Irregular or
Absent on page 6-12.
3. Pilot assembly is operating
incorrectly.
• Refer to Pilot Ignition Irregular or
Absent on page 6-12.
4. Exhaust sail switch does
not have enough air to
operate.
• Check for lint build up on the sail switch.
Refer to Check and Clean Sail Switch
and Exhaust Blower Wheel on page
4-11.
• With the unit running, check the circuit
for the sail switch by testing for 120 V
between terminals 5, 6 and GND in the
main electrical box. If 120 V is not pres-
ent, the sail switch is bad and must be
replaced.
TEMPERATURE Control Er-
ratic or Does Not Work
1. Operators are not using
the full length of the ironing
cylinder. This causes the
cylinder ends to heat up
and temperature to fluctu-
ate up and down.
• Refer to Flatwork Handling on page
3-9.
2. TEMPERATURE Control is
not working properly.
• Replace the TEMPERATURE control.
Refer to Temperature Control or High
