Bryant 395CAV furnace - goes out randomly (5 flash LED code). Cycle power - works temporaily. Out again and redo process. Thoughts?

You may have burnt out your heat exchanger big $$$$ to fix

You need to have/ know the "fault code" chart for that specific furnace. Count the number of flashes and refer to chart. Look on the inside of the furnace blower door or other panel. Also look up on internet and print it off. If the furnace was allowed to run during the remodel it voids the warranty automatically. Read the installation manual.
Try resetting the electronic board by turning the power off then back on.

A sampling of various failure codes on a furnace:

Read one LED flash that stays on continuously to mean your furnace has no signal coming from the thermostat and will not operate. Turn the power off and check the thermostat for improper settings or connections.

Interpret one LED flash that blinks on and off to mean your furnace has locked out because it could not ignite after three tries, and must be reset. Interrupt power to your furnace for 20 seconds or lower the thermostat so your furnace does not try to heat, then reset the thermostat to the previous setting. After one hour of lockout, your furnace will automatically reset itself and try to operate as usual.

Decipher two LED flashes to mean the draft blower is not working, or your furnace has a short in the pressure switch circuit. Turn off the furnace power and repair a short or replace the pressure switch.


Read three LED flashes to mean your furnace has an open pressure switch circuit or it has an induced draft blower operating. Check the pressure switch hose of your furnace for blocks or an improper connection. Also, look for blockages in the flue, and tighten any loose wiring.

Translate four LED flashes to mean your furnace has a primary limit circuit open, possibly from loose wiring or blocked filters. Check and clean filters, tighten wiring and check the flue for blockages.

Interpret five LED flashes to mean your furnace senses a flame without a call for heat. This could be from a gas valve closing slowly or a burner flame lingering.



Read seven LED flashes as a warning of a low flame sense microamp signal. This could happen with a coated flame sensor or a lazy flame from poor gas pressure. Turn off the power and adjust the gas pressure according to the information on the rating plate.



See eight LED flashes as meaning an igniter circuit problem due to a bad igniter or an igniter connected improperly. Replace the bad igniter or check the ground wiring, making necessary corrections.



Decipher nine LED flashes to mean the high-stage pressure switch circuit will not close during a high-stage-induced draft blower operation. Your furnace may have a pinched or blocked pressure switch hose, a blocked flue or loose wiring.

Read continuous flashing on the LED to mean your furnace has a reversed polarity of 115 volts. Turn off the power and correct the wiring polarity after reviewing the wiring diagram.

these codes are on the inside panel of the front cover of the furnace. lift off and look inside.there should be a code explain chart on the panel by the light. this panel will need to be replace correctly for the furnace to work as there is a door switch.

If you have a Bryant split system, that is gas fired, and you are having a problem with it because of a flashing led, you need to remove the panel to excess the glued on chart that will tell you what the code is according to the amount of flashes its showing you. You may have 2 long flashes and one long, or something different? Look at the chart inside, and it will tell you what is wrong.

You can follow these instructions to change the code of yours. Might work for you.

NOTE: You must change the transmitter's code before programming the transmitter to the motor head unit.
The following steps describe the process to change a Quantum™ and Classicdrive™ security code.
This process only works fro transmitters with a GREEN LED and a "U" in their model number, such as "02-3047 2B U" or "02-3047 2B UH".
Changing the Transmitter Code
1. Press and hold the button on the transmitter that you want to change. The GREEN LED will flash once and then turn off.
2. Continue to hold the button until the GREEN LED begins to flash (approx. 10 seconds).
3. When the GREEN LED flashes, immediately release the button and then immediately press and hold the same button again. The GREEN LED will now come on steady.
4. Continue to hold the button until the GREEN LED begins to flash (approx. 5 seconds).
5. When the GREEN LED flashes, immediately release the button.
6. The code for this button has now been changed to a new randomly generated code. Do not push the button again until instructed in "Programming Transmitter to Power Head Unit".
7. You must now re-program this transmitter to the motor head unit. See "Programming Transmitter to Power Head Unit".
Programming Transmitter to Power Head Unit
1. Press the PROGRAM button located on the garage door motor head unit once. The PROGRAM STATUS light on the motor head unit will turn on and remain lit for one minute, indicating that it is ready to learn the Transmitter code.
2. Press the same button on transmitter as you did in "Changing Transmitter's Code" above. The PROGRAM STATUS light will turn off indicating a successful learn.
3. Press the same button on the Transmitter once more to operate the door.
4. If you are unsuccessful in programming the transmitter to the motor head unit of if the button does not operate the door or if you wish to program another button to operate a different door, you must change the transmitter's code.
Battery
If the LED does not turn on when button is pressed, replace battery.

high limit is open try tapping on it gently

'Limit or flame rollout switch is open'. In my case, the flame rollout switch had tripped due to an overheating? I had to push the button between the wire leads to reset the switch. Then when I turned the power back on, the furnace started up like normal.

Why did the switch overheat and trip? My current theory is that there was a rubber grommet around a pipe near the switch that had slid down and was no longer sealing the furnace?

Look on the blower door panel in the wiring diagram there should be a flash code but it sounds like the flame sensor is not picking up the flame and you may be able to clean it
