You may have a bad or dirty Flame Rod which is located in the flame of the last burner that fires up. It is a small diameter rod with just one wire the goes down to the control board. Clean it with a tooth brush or scrub pad. Check connection at control board or replace it.

12 year old HE York diamond 90 furnace burners ignite for a few seconds but won't remain lit. Hot surface igniter then glows and burners again light momentarily. Cycle repeats several times before blo


The flame sensor can still be faulty, replacing that is the cheapest. Other issues could be a faulty control board (if available), a faulty gas valve, thermostat lossing call, or a safety/pressure switch problem. There are alot of variables and it really helps to have a meter to check voltage and continuity through-out the system.

Luxaire by York Furnace,Model# G8T10012UHB11A,8 Red LED Flashes = Ignition lockout due to recycles,Has flame for a few seconds then goes off; does it around three times,Fan is working; blowing cold air


It sounds like you have a dirty or bad Flame Sensor. They sometimes get a white coating on them. It's not detecting a flame so it shuts off. Sometimes you can clean them and they will work.

My goodman furnace keeps lighting for about 10 seconds than goes out lots of clicking sounds


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad igniter what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat.
2. Draft inducer motor starts.
3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes.
4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas.
Solution: You probably need to purchase and install a new igniter. I would suggest that you inspect your igniter closely for cracks. Make sure you do not touch the igniter with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, roll-out switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

I have a York Diamond 90 furnace and when i try to start it, the pilot light goes on then it shoots the flame into the furance, but will shut down a minute or so after that. It sounds like the blower is...


The furnace is not sensing the flame. Turn off the power.
There is a metal rod in front of the last burner to light. It is corroded and needs to be cleaned. Its the flame sensor .
take the 1 screw out holding it in to the bar and scrub it with some steel wool till shiny. replace and turn on furnace. all should be fine.

Gas furnace; flame will not stay on


Clean the flame sensor with a green scotch brite pad. Check all ground connections from the circuit board to the furnace cabinet. Check for a proper ground to the electrical box. Make sure polarity has not been reversed.

My york diamond 80 can be fired up, but it is shut off automaticaly after approx. 20sec. This can be repeated 3 times. I beleive the fun and borad panel are working fine.


The flame sensor might have dust build up on it. The flame sensor makes sure that the system has ignited before it starts the main blower. If it ignite and burns for 15-20 seconds then goes out that is most likely your problem. Identify a probe that is in the direct path of the flame(usually in the last burner tube from the gas source), it will have one wire coming off of it and usually has one screw holding it in place. As time goes by the sensor will get a build up on it and stop functioning. Turn the power to your furnace off, then remove the screw and then gently pull the flame sensor out. Using a MILD abrasive like panty hose of paper towel (DO NOT USE sand paper) clean the sensor and then put it back into place. Tighten the screw and then turn your furnace back on. That should fix your problem.
