If it opens after trial for ignitionperiod, blower will come on for 90 second recycle delay.- Disconnected or obstructed pressure tubing.- Defective blower motor or start capacitor. - Dirty filter or restricted duct system.- Loose blower wheel. - Defective switch or connections.- Inadequate combustion air supply (flame rollout switch only).- Open flame rollout switch, manual reset.- Oxide buildup on flame sensor (clean with fine sandpaper).- Proper flame sense microamps (.5 microamps D.C. minimum).- Gas valve turned off. - Manual shut-off valve.- Green wire MUST be connected to furnace sheet metal.- Inadequate flame carryover or rough ignition.- Low inlet gas pressure.SERVICECOMPONENT TEST123456789STATUSTEST HUM C W Y R G320615-102 REV. ATo initiate the component test sequence, shut OFF the room thermostat or disconnect the "R"thermostat lead. Briefly short the TEST terminal to the "C" terminal. Status LED will flash codeand then turn on the inducer motor, hot surface igniter, blower motor-heat speed, and blowermotor-cool speed for 10-15 seconds each. BLOWER OFFDELAY SELECTEACH OF THE FOLLOWING STATUS CODES IS A TWO DIGIT NUMBER WITH THE FIRSTDIGIT DETERMINED BY THE NUMBER OF SHORT FLASHES AND THE SECOND DIGITBY THE NUMBER OF LONG FLASHES.LED CODECONTINUOUS OFFCONTINUOUS ONRAPID FLASHING- Check for 115VAC at L1 and L2, and 24VAC at SEC-1 and SEC-2.- Control has 24V power.- Line voltage (115V) polarity reversed. If twinned, 24V power toone furnace may be out of phase with 24V power to other furnace.STATUS1112131421222324313334NO PREVIOUS CODE - Stored status codes are erased when power (115V or 24V) tocontrol is interrupted or 48 hours after each fault is cleared.BLOWER ON AFTER POWER UP (115V OR 24V) - Blower runs for 90 seconds, if unitis powered up during a call for heat (R-W closed).LIMIT OR FLAME ROLLOUT SWITCH LOCKOUT - Auto reset after three hours. Flamerollout switch requires manual reset. Refer to #33.IGNITION LOCKOUT - Control will auto-reset after three hours. Refer to #34.GAS HEATING LOCKOUT - Control will NOT auto reset.Check for:ABNORMAL FLAME-PROVING SIGNAL - Flame is proved while gas valve isde-energized. Inducer will run until fault is cleared.Check for:PRESSURE SWITCH DID NOT OPEN Check for:SECONDARY VOLTAGE FUSE IS OPENCheck for:PRESSURE, DRAFT SAFEGUARD, OR AUXILIARY LIMIT (when used) SWITCH DIDNOT CLOSE OR REOPENED - If open longer than five minutes, inducer shuts off for15 minutes before retry. Check for:LIMIT OR FLAME ROLLOUT SWITCH IS OPEN - If open longer than three minutes, codechanges to #13. Check for:IGNITION PROVING FAILURE - Control will try three more times before a lockout #14occurs. If flame signal lost after trial for ignition period, blower will come on for 90 secondrecycle delay.Check for:SERVICE LABEL9
