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. indicator will go out and the display will read “bURNER CONTROL 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 CONTROL 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.
