SOURCE: flame rollout sensor keeps tripping

The flame rollout sensor is a rather important safety feature that ideally only trips when there's an overtemperture outside of the combustion chamber. I'd encourage you to get a better quality tech in ASAP to check for a cracked heat exchanger, gas overpressure, restricted airflow (changed the filter lately?), maybe a blocked condensate drain if this is a high efficiency furnace. If the sensor was replaced and it's still tripping, you've got a potentially dangerous overheating issue that you don't want to try to bypass.

SOURCE: flame rollout switch keeps tripping

it means the flame is rolling out..... generally indicates a blockage in heat exchanger, or flue pipe, or combustion fan is not turning a correct rpm.

SOURCE: Carrier 48GP rollout switch code

You need to find the rollout switch and see if it has a manual reset button on it or not. There are 3 styles of rollout controls. One is a disc type that mounts behind the burner ends, there may be more that one,possibly one on each side of the burner tray. This style rollout is usually manual resetting. It most likely will be black or silver in color and usually is about the size of a penny in diameter and about 1/2" in thickness with 2 wires going into it and a red push type button in the middle. The next style is similar two the first as it is manual resetting also, but this rollout uses a small copper capillary tube that runs just behind the burner ends and is mounted to the burner tray. If you follow this tube it will lead you to the manual reset button which is most likely mounted below the burner tray. The last style rollout is what they call a fuseable link, this is mounted behind a burner end and looks like a resister used in electronics, it is about 3/4" long and about 3/16" in length and is silver in color. It is mounted in a porcelain mount. This style is not resettable it has to be replaced with one of the same temperature rating. You would need to go to a Carrier/Bryant dealer to get the right one. Either take it with you or bring the model and serial number of your furnace.
The most important thing about rollouts is that there is a reason it opened up(went faulty). The reason they trip or open up is due to the burner flames are rolling back out of the burner box and getting the rollouts hot enough to trip or open up. This is telling you there is a serious issue with your furnace that needs to be found and repaired. There are a couple of things that is causing this. They are that your exhaust is not venting properly. Your exhaust venting could be restricted with whatever. You need to pull your venting off and look for restrictions all the way from your heater to the end of the chimney. The next thing it could be is that your heat exchanger is cracked enough to allow positve air pressure on the exhaust system when the indoor blower fan is running. You can check this out yourself by watching the burner flames when the indoor fan comes on. If the heat exchanger is cracked enough the burner flames will flutter or move back toward you when the indoor fan comes on causing the rollout to trip or open up. Most manufacturers have a 20 year warranty on the heat exchanger(parts only,you pay the labor cost). Depending on the age and condition of your furnace it may not pay to have the heat exchanger replaced.
I hope I was able to steer you in the right direction!! Good luck!!

What does it mean when my goodman furnace is flashing a red light and will not work.


It is in Lockout mode. Something has happened to make it go into lockout.
It could be an easy fix. Look of cobwebs in the tubing between the proving switch and the draft inducer motor. Look for air restrictions in the chimney flue. Rusty burners (if applicable). Tripped rollout switches. Some times there could be up to 2 roll out switches on the burner and another in the flue and 2 others in between stuff. . Most times it is a dirty flame sensor. Over the summer the flame sensor gets dusty and the sensitivity gets off. The control fails to FEEL the probe and locks out the gas valve. Most times the failure will be defines by the amount of blinks the red light emits. The sub panel has a guide on it that tells what the blinks mean.

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.

I have a Carrier Weathermaker SXi. Furnance will not turn on. I shut power off and waited ten minutes and tried to restart. Codes flashing are 12, 31, 32, 33, 41, 42. Can this be started in emergency mode?


Emergency heat is made for this kind of situation.So yes you can.
now for the codes.
code 12= Blower on after power up
code 31=High heat pressure switch or relay didn't close or reopened
code 32=Low heat pressure switch or relay didn't close or reopened
code 33=limit circuit fault(Flame rollout switch is open)
code 41=board fault
code 42=control lockout

Arcoair central heat /air conditioning unit


The blower motor kicks on when there has been a 24 volt control failure.

This usually means that a limit switch has tripped.

Most likely that would be a high temp limit switch or a rollout switch.

First, make sure the filters are clean. and the evap coil is clean. If eaither are dirty/clogged, it will partially block airflow, causing the furnace to overheat, causing the high temp limit to trip.

A rollout switch typically trips for three reasons.
1 flame rollout into the burner compartment due to poor airflow.
2 overheating af teh metal plate the rollout is mounted to, due to dirty, old, rusted components.
3 a bad limit switch.

If your unit has an LED light, count the flashes and it will hepl popint out the problem.
(locate the wiring diagram/flash code list, and correspond the flash count, with the code.)

First, check filters.

you probably have a cracked heat exchanger which is causing the rollout switches to trip.even the tiniest of cracks will cause the fan to blow the flame back into the unit and cause them to trip. check the heat exchanger for even the tiniest of cracks if so replace it. and be sure to have a carbon monoxide alarm in your home.
