Carrier 48ss rollout switch fault

The led light for my carrier 48ss 036100331-- is flashing 7 times which corresponds to the rollout switch. What could cause this. The burner ignites and then goes out shortly after heating starts. Thanks in advance.

SOURCE: Carrier 48gs-024060301. Rollout switch fault.

Juno out the switch and see if the unit fires. You may have more than one. Check the wiring diagram for sure.

SOURCE: My Carrier Air Cond. 14 yr old, Model No.

Older furnaces used a bi-metal fan-limit to turn on the fan motor. The newer ones use a timing relay on the board. Get a new board and both problems will go away most likely. The 8 flashes has to do with bad ignitor or loose ground on many of these newer machines which obviously has nothing to do with your ignitor since you didn't mention having a probo with it. This to me seems to be a board gone bad.

My carrier model # 48ss-036100331 induced-draft motor will not start


On some of those inducer motors there is also a capacitor in the blower compartment on the left side of the burner section. It is possible that if you have 230v coming from the board CM terminals and if the motor is new maybe you have a bad capacitor in the blower section. Follow the wires to the capacitor and check microfarad reading to that capacitor. Caution there maybe 2 in this area but one is for the indoor blower motor and the other will be for the draft motor. The blower capacitor may be somewhere between 10 or 15 mfd but the draft inducer capacitor will be around 3 mfd. hope this helps

Hi, the lights on my circiut board are flashing the one on the left is on all the time and the one to the right of it flashes two times and then waits and then flashes two times again


Error Codes
A green LED indicates system faults
Steady On: System OK
Steady OFF: Board control fault or no power applied
1 Flash: Ignition failure (control in one-hour lockout)
2 Flashes: Pressure switch fault, fails open (switch is
stuck open)
3 Flashes: Limit switch open (main or auxiliary)
4 Flashes: Pressure switch fault, fails closed (switch is
stuck closed)
A yellow LED indicates flame status
Steady on: Normal flame is sensed
Flashes: As flame weakens, frequency of LED flashes
increases

hope this is helpful.

Have a 48ss 036080311aa Carrier packaged unit , flame is rolling out and heat is going down on the overheat sensor, getting 7 flashes on the controler board


Hello my name is Heath it will be my pleasure to assit you. It sounds like the heat exchanger is plugged. Pull the burners and use a shop vac an clean the heat exhanger out real good use a brush if you have one long enough to brush the heat exchanger out.

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.

Heat would not come on and fan would not cut off even when thermostat was set to off. Took off the outside panel of the unit and red light was blinking 7 times - rollout switch fault. Since fan would not...


this means that the rollout switch was tripped by a flame coming from burners. could be a plugged fue or bad inducer motor, or a bad rollout switch. the fan will not shut off as a safety feature it keeps running incase the heat exchanger is to hot to keep a fire from starting. it will shut off after disconnecting power and restarting everything. watch the flames from burner when it lights to see if the actually roolout of the burner box toward the rollout sensor.

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.
