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

Rheem furnace problem wont stay lit


You need to see what it does. Does it light at all? will the pilot stay on? If lights but wont let you release the knob then thermocouple is bad. I
If it is electric start then watch the series of events. enducer fan motor starts, element heats up, gas lights but shuts off after 1 second. 5 seconds 1 minute and so on. Also your computer board on the furnace will flash a code indicating a problem. count the flashes and read the panel on the furnace for help it should give a description of the the errors.
all depends on the age and type of unit. respond if you have more questions .

Model G5RA096C-16 motherboard light flashes one time pauses then flashes again and so on. The furnace turns on and blower turns on but does not heat. What does the flashing light mean?


Your furnace is off on a safety limit. Look for small thermal disks around the burner area they will have a usually red switch in the center and 2 wires coming into it. Reset this and watch furnace run. These are called rollout switches and they trip when you have flame rollout. SO WATCH IT RUN. If you have flame rollout you will most likely have a cracked heat exchanger if so you will need a new heat exchanger or new furnace. Next the number of flashes is important on some furnaces it will tell you what part is faulty. Count the flashes then on one of the furnace covers is the wiring diagram it will tell you what the flashes mean otherwise you can tell me and Ill help you out, WHen you reset the power on the furnace does it try to heat tell me what all happens when you shut the switch off then back on. when you turnit back on make sure the stat is calling for heat,

My central heating is on lockout and the burner is with red light


A sampling of various 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 Goodman 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.

Bryant furnace codes


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.

Furnace blows cold air, ignitor won't glow.


ok this is going to sound funny but it seems as though the polarity is reversed going into your furnance. to correct this proiblem you first need to unplug the unit and where the cord goes into the furnance at that connection disconnect the two wires. Once theses are disconnected switch the wires .All you are doing is reversing the way the electricity flows into the circut board. I would wager that is the problem
