bryant furnace codes
Each of the surveil status codes is a two digit number with the first digit determined by phone number of flashes of the yellow led and the second finger determined by numeral of flashes of the k led .
Like many furnace manufacturers, Bryant uses flashing LED lights to indicate error codes that can give you an estimate of what ‘s wrong with your furnace when it ‘s not officiate properly. The shortstop flashes indicate the first digit of the two-digit code, and the long flashes indicate the second gear finger. here ‘s are some common error codes .
CODE: RED LED1 ON.
RESULT: Furnace is operating in emergency heat .
CODE: RED LED2 ON.
RESULT: The microprocessor has malfunctioned. To reset : Put setup switch “ SW-1 ” in the “ ON ” position nad sweater thermostat terminals “ R ”, “ W/W1 ” and “ Y/Y2 ” simultaneously with the door substitution pushed in and world power to the unit “ ON ”. Disconnect sweater and place setup switch in the “ OFF ” put. If LED2 reappears, replace independent control dining table.
CODE: YELLOW LED3 ON.
RESULT: Furnace is operating in high heat .
CODE: GREEN LED4 ON.
RESULT: Furnace is operating in low estrus .
CODE: RED LED2 FLASHING.
RESULT: Line voltage mutual opposition is reversed .
RESULT: NO FAULT IN RECENT HISTORY DISPLAY
FIX: Indicates no faults have occurred within the end five cycles. To read recent fault history, put apparatus substitution “ SW-1 ” in the “ ON ” position. To clear recent fault history, put apparatus switch over “ SW-1 ” in the “ ON ” position and jumper thermostat terminals “ R ”, “ W/W1 ” and “ Y/Y2 ” simultaneously until an “ 11 ” is flashed .
RESULT: BLOWER CALIBRATION LOCKOUT
FIX: Indicates RPM calculated for low heat was less than 250 RPM or greater than 1300 RPM on two consecutive attempts. Auto reset after three hours. Reset ability and refer to fault # 44 part .
RESULT: LIMIT SWITCH LOCKOUT
FIX: Indicates the occurrence of 10 consecutive limit trips during eminent heat or three consecutive limit trips during low heat. Auto reset after three hours. Check for *Improper or misaligned limit and/or limit harbor. *Improper high or low heat gas input signal adaptation. *Stuck high heat solenoid in gas valve .
RESULT: IGNITION LOCKOUT
FIX: Control will auto-reset after three hours .
RESULT: INVALID MODEL SELECTION
FIX: Indicates model punch is missing or faulty. See wiring diagram for right connection jumper placement .
RESULT: SETUP ERROR
FIX: Indicates setup switch “ SW-1 ” or “ SW-6 ” is positioned improperly. The follow combinations will cause the fault : *Thermostat visit with “ SW-1 ” “ ON ”, or Thermostat call with “ SW-6 ” “ ON ”, or “ SW-1 ” and “ SW-6 ” both “ ON ” together.
RESULT: INVALID BLOWER AIRFLOW SELECTION
FIX: Indicates improper “ A/C ” or “ CF ” interchange setting. The 042 and 14 units can deliver 1-1/2 to 3-1/2 tons A/C and 600 to 1400 CFM for continuous sports fan. The 060 and 20 unit of measurement can deliver 2 to 5 tons A/C and 800 to 2000 CFM for continuous fan. If code is flashing, unit will default tp closest allowable airflow .
RESULT: SECONDARY VOLTAGE FUSE IS OPEN
FIX: Check for : – Short circuit in secondary voltage ( 24VAC ) wiring .
RESULT: PRESSURE SWITCH DID NOT CLOSE OR REOPENED
FIX: If open longer than five minutes, persuader shuts off for 15 minutes before rehear. Check for : – excessive wind – proper vent size — defective inducer drive – first gear persuader electric potential ( 115VAC ) – defective blackmail switch -Inadequate combustion air supply – Restricted vent – Disconnected or obstructed pressure tubing – humble inlet accelerator press ( if LGPS used ) If it opens during blower ondelay period, cetacean will come on for the selected blower off-delay .
RESULT: LIMIT CIRCUIT FAULT
FIX: Indicates a specify, or flame rollout is open. Blower will run for 4 minutes or until open switch remakes whichever is longer. If open longer than 3 minutes, code changes to lockout # 13. If open less than 3 minutes condition code # 33 continues to flash until blower shuts of Flame rollout switch requires manual readjust. Check for : – Restricted vent – proper release sizing – idle electric fan rack – excessive wind – dirty percolate or restricted duct organization. – defective cetacean motor or capacitor. – bad switch or connections. – inadequate combustion air provision ( Flame Roll-out Switch open ) .
RESULT: IGNITION PROVING FAILURE
FIX: Control will try three more times before lockout # 14 occurs. If fire signal lost during blower on-delay period, electric fan will come on for the selected blower off-delay. Check for : – control anchor continuity – flame detector must not be grounded – Oxide buildup on fire detector ( clean with finely steel wool ) – proper flame common sense microamps ( .5 microamps D.C. min., 4.0 – 6.0 nominal ). – Gas valve defective or boast valve turned off – manual valve shut-off – defective Hot Surface Ignitor – gloomy inlet natural gas pressure – inadequate flame carryover or rough ignition – Green/Yellow wire MUST be connected to furnace sheet metallic .
RESULT: BLOWER OUTSIDE VALID SPEED RANGE
FIX: Indicates the cetacean is not operating at the account RPM. If this fault occurs in conjunction with defect # 44 check electrify to motor differently denote to the trouble-shoot guidebook .
RESULT: INDUCER OUTSIDE VALID SPEED RANGE
FIX: Indicates the persuader is not operating at the deliberate RPM. Or it has not started within 10 seconds after a call for heat. Check wiring to motor otherwise mention to the troubleshooting scout .
RESULT: PRESSURE SWITCH CALIBRATION FAULT
FIX: Indicates the broken and high coerce switch “ make ” points during high heating system flush are not within calibration range. Check for : -Plugged condensate drain Water in vent worst, possibly sagging shriek -Improper pressure switch wire or atmospheric pressure switch tubing connections -Failed or “ out of calibration ” press switches .
RESULT: BLOWER CALIBRATION FAULT
FIX: Indicates the count blower focal ratio is below 250 or above 1300 RPM. Unit will default to low or high inflame mode if potential. If this fault occurs in conjunection with fault # 41, assay wire to motor differently mention to the disturb shooting guide. If this fault occurs by itself, check for undersize ductwork, or excessive inactive caused by a dirty filter, or closed registers.
RESULT: CONTROL CIRCUITRY LOCKOUT
FIX: Auto-reset after one hour lockout due to ; – Gas valve relay stuck open – fire sense circuit bankruptcy – Software check error Reset ability to clear lockout. Replace see if status code repeats .
