Code 31 is a pressure failure...

Hello JT Beltran,

Cyber-"wisdom" has it as a PRESSURE SWITCH FAILURE
(not closed)...
((DON'T short past it... unless you know what you are doing)).

Usually reserved for heaters with really filthy ... heavily clogged FILTERS... or blocked duct work (too many closed vents)

Once you have eliminated the obvious fire hazards of blocked AIR circulation, checked your filter is INDEED CLEAN &
unobstructed...YOU HAVE the (un-likely) faulty pressure switch...

Hope this helps.

SOURCE: Carrier 58STA/STX furnace false starts even when off or temperature set lower than current.

Is it possible the drain is plugged? The newer furnaces have a moisture drain and will shut down if they are blocked., shutting them down and restarting will reset fault, but will come right back if not fixed.

Carrier 58STA furnace code 33, no ignition blower stays on. I have a Carrier 58STA furnace. It's getting a code 33 and never trying to ignite. The blower constantly stays on. It is pushing good air...


33 is a limit switch open take your furnace doors off and there should be a wiring diagram. on this furnace the blower will run if this is open. check rool out swict and linits. it sounds like you have a problem with over heating. how does the fire look ? is the vent blocked ? things like thathttp://www.scribd.com/doc/20861415/Carrier-58pav-Service-Maint i think page 9 has falt codes

What are the carrier 8000ts led error codes?


They are listed inside the front panel of the main unit.

LED CODE

EACH OF THE FOLLOWING STATUS CODES IS A TWO DIGIT NUMBER WITH THE FIRST

DIGIT DETERMINED BY THE NUMBER OF SHORT FLASHES AND THE SECOND DIGIT BY

THE NUMBER OF LONG FLASHES.

STATUS

11 NO PREVIOUS CODE - Stored status code is erased automatically after 72

hours. On RED LED boards stored status codes can also be erased when power

(115 VAC or 24 VAC) to control is interrupted.

12 BLOWER ON AFTER POWER UP (115 VAC or 24 VAC) -Blower runs for 90

seconds, if unit is powered up during a call for heat (R-W closed) or R-W opens

during blower on-delay.

13 LIMIT CIRCUIT LOCKOUT - Lockout occurs if the limit or flame rollout switch is

open longer than 3 minutes.

- Control will auto reset after three hours. - Refer to #33.

14 IGNITION LOCKOUT - Control will auto-reset after three hours. Refer to #34.

21 GAS HEATING LOCKOUT - Control will NOT auto reset.

Check for: - Mis-wired gas valve -Defective control (valve relay)

22 ABNORMAL FLAME-PROVING SIGNAL - Flame is proved while gas valve is

de-energized. Inducer will run until fault is cleared. Check for:

- Leaky gas valve - Stuck-open gas valve

23 PRESSURE SWITCH DID NOT OPEN Check for:

- Obstructed pressure tubing. - Pressure switch stuck closed.

24 SECONDARY VOLTAGE FUSE IS OPEN Check for:

- Short circuit in secondary voltage (24VAC) wiring.

31 PRESSURE SWITCH DID NOT CLOSE OR REOPENED - If open longer than

five minutes, inducer shuts off for 15 minutes before retry. Check for:

- Excessive wind - Proper vent sizing - Defective inducer motor

- Low inducer voltage (115VAC) - Defective pressure switch

- Inadequate combustion air supply - Restricted vent

- Disconnected or obstructed pressure tubing

- Low inlet gas pressure (if LGPS used)

If it opens during blower on-delay period, blower will come on for the selected

blower off-delay.

33 LIMIT CIRCUIT FAULT - Indicates a limit, 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

status code #33 continues to flash until blower shuts off. Flame rollout switch

requires manual reset. Check for: - Restricted vent

- Proper vent sizing - Loose blower wheel - Excessive wind

- Dirty filter or restricted duct system.

- Defective blower motor or capacitor. - Defective switch or connections.

- Inadequate combustion air supply (Flame Roll-out Switch open).

34 IGNITION PROVING FAILURE - Control will try three more times before lockout

#14 occurs. If flame signal lost during blower on-delay period, blower will come

on for the selected blower off-delay. Check for: - Control ground continuity

- Flame sensor must not be grounded

- Oxide buildup on flame sensor (clean with fine steel wool).

- Proper flame sense microamps (.5 microamps D.C. min., 4.0 - 6.0 nominal).

- Gas valve defective or gas valve turned off - Manual valve shut-off

- Defective Hot Surface Ignitor

- Low inlet gas pressure

- Inadequate flame carryover or rough ignition

- Green/Yellow wire MUST be connected to furnace sheet metal

45 CONTROL CIRCUITRY LOCKOUT Auto-reset after one hour lockout due to;

- Gas valve relay stuck open - Flame sense circuit failure

- Software check error

Reset power to clear lockout. Replace control if status code repeats.

If status code recall is needed, briefly remove then reconnect one main limit wire to display

stored status code. On RED LED boards do not remove power or blower door before initiating

status code recall. After one status code recall is completed component test will occur.


Thanks for Choosing FixYa.

My carrier 58sta furncace is blowing cold air constantly


Code 33 is "limit is open or flame switch is open"
FIRST make sure the filter is clean. Turn off unit then turn back on.
if it works but then later gives you a 33 code then you might have a dirty a/c coil (if you have a/c) that will cause the limit to open. 1st try that

Heat not coming on carrier gas pack code 31


code 31 indicates pressure switch did not close or reopened during the heat cycle....1st thing to check is the inducer motor,,this is a small motor that turns a small blower wheel that draws the exhaust gases through the furnace and blows them into the vent pipe....1st locate the inducer assembly,,most easily identified by the small plastic fan blade that cools the inducer motor as it runs..1st turn off tstat and turn off furnace power switch..then turn on furnace switch,then set tstat to heat,set the temp above room temp by 5 degrees...remove the furnace front cover,locate the inducer motor,,if it isnt turning,but is warm or hot after a minute or so,likely the inducer motor is bad..if it isnt turning and isnt warm after 1 minute,then likely the main control board is bad,,not turning the inducer motor when it should,,,,,if the inducer motor is running,,then the pressure switch isnt closing,, could be a bad pressure switch but more likely there is a problem with the venting...some possible problems that would cause the pressure switch not to close in an 80% eff furnace [metal vent pipe] are: [1] a blockage in the vent pipe,base of chimney,dead bird at the furnace where vent connects to furnace or down inside the inducer assy,accessed by removing vent pipe from furnace....if all clear the chimney could be blocked up inside,,is the draft good when vent is removed from base of chimney?..if furnace is a 90%+ type [pvc plastic vent pipe],,then check the intake pipe at the furnace by removing it where it attaches to top of furnace..is the intake clogged with anything?..then check the intake and exhaust pipes outside for blockages,,including ice/frost/snow at the exhaust pipe outlet..

Need to stat brand name of equipment, differant manufacturers use different codes. There should be a listing on the front panel or on the inside of blower door with the wiring diagram. On some Carrier type it would be a code 31 , for inducer motor (vent motor) on a gas furnace or the pressure switch not making
