12. “FLAME” (bURNER CONTROL FAIL) Input L.E.D. Indicator
a. This routine monitors the ignition control’s gas valve output response. If the valve output signal is not
present from the ignition control within the valve time limits the microprocessor determines the
ignition control has failed. If this occurs when the cycle is active the “FLAME” output L.E.D. (light
emitting diode) indicator will go out and the display will read “bURNER CONTRL FAIL.” The
machine will run with no heat for three (3) minutes or until the temp drops below 100º F (38º C).
Then the machine will shut down still displaying “bURNER CONTRL FAIL” with an audio indication.
13. “POWER SUPPLY” Input L.E.D. Indicator
a. Should be on at ALL times (even if the dryer is not running). The power supply L.E.D. (light
emitting diode) output indicator will not be on if the power supply fuse to the Phase 6 OPL
microprocessor is not present. If the power supply fuse is faulty the L.E.D. output will be off and
there will be no display or keyboard (touchpad) function. The “FUSE,” “LINT,” and “DRUM”
output L.E.D. indicators will remain on.
