To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the dryer(s) before servicing.
• Close gas shut-off valve to gas dryer(s) before servicing.
• Never start the dryer(s) with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the dryer is properly grounded.

14. IGNITION CONTROL FLASHES
(Figure 1)
NOTE: This control will lock-out the igniter after four failed attempts at ignition. The control can be reset by
opening loading door, waiting 1 minute, then closing loading door. If door is closed before waiting 1 minute, the
control will re-enter lockout. The red light will flash a “Flash Code” when the control is in the lock-out mode. The
light will flash on for 1/4 second then off for 1/4 second for each number. The pause between flash codes is 2
seconds. These flashes are caused by the control’s diagnostic test and can be interpreted by reading the following:
FLASH CODE POSSIBLE CAUSE TO CORRECT
Constant Light Internal failure. • Reset dryer. If condition persists, then
replace control.
One Flash Air in gas line. • Purge air from gas line.
