Check to make sure your roof vent cap has not come off. This will cause this to happen. If its there, shut unit off, and pull out the burners that are not working. Just push forward and tilt the back end up to remove them. Turn them over and tap the rust and dirt from them. Reinstall them. Make sure they are in place right. This will solve your problem. This is why you smell raw gas.

Installed new gas valve. Wired according to instructions with valve. Shows 3 wires coming from igniter to gas valve. 2 tabs on valve above pilot. Burners won't come on.


I need more info to help you out. You need to check if there is anything else wrong with the furnace. But a for the gas valve goes you nee to check if your geting 24 volts to the gas valve. The pilot sensor might be bad. What kind of gas valve do you have. are the three wires coming back to gas valve Yellow, White, and Green. If they are most likly its the flame sensor not the gas valve.

FURNACE MAKES STRANGE INTERMITTENT CLICK SOUND


Measure the voltage to Terminals #2 and #3 on the main gas valve. If the voltage remains consistent while you hear the sound and the burners diminish slightly, the problem will be your main gas valve. If the voltage fluctuates, you will have to trace it back through the wiring to see through which switch you are losing it.
If this furnace has a hot surface ignitor with flame sensor, try cleaning the flame sensor with some emory cloth.

I hope you find this information to be very helpful as a good starting off point for you.

Please leave a rating. :-)

Intertherm gas furnace


It appears your furnace is a downflow furnace. The sensor will be located near the bottom of the furnace. When you first turn it on, you should see a red glow.....this is the hot surface ignitor. Normally, the Hot Surface Ignitor is located on one end of the burners and the Flame Sensor is located on the oppoosite end of the Burners.

You need to check gas vent ASAP. You should not be getting any odors from your furnace. Have a technician check your furnace. Could have hole in Heat exchanger. If so you and anyone else there are in danger. Please do not operate till it has been checked. Very very dangerous Rus

Oven has small explosion igniting and going off. says tj


A few years back I helped a neighbor with this same problem in a forced air, gas fired, "horizontal" furnace in his attic.

After having him cycle the thermostat a couple dozen times while I watched through the opening in the side of the furnace, I finally figured out what was happening.

First, there were about 6 cast iron burners [about 14 inches long with two rows of gas holes along the length]. These burners were parallel to each other and oriented perpendicular to the long axis of the furnace.

The gas was fed to the ends of the burners with a pipe manifold. The standing pilot light was at the center between burners 3 and 4. Due to the spacing distance between the burners, the pilot light was too far from even burners 3 and 4, the flame could not "jump" to ignite them, or any of the other burners. The manufacturer had installed a thin sheet metal "tent" which ran from the gas entrance end of burner 1 to burner 6, and was about 2 inches above the burner, AND the pilot light.

The standing pilot was on all the time. When the gas control valve turned on, gas began to come out of all the burners at the same time. Naturally it came out of the gas supply manifold ends of all the burners.

The "tent" captured that gas coming from the burners and "filled" up to over the pilot light which ignited the gas at that point, and the flame would propagate along the tent to ignite the gas coming out of all of the burners.

In my neighbors case, the tent had somehow become dislodged so that it did not cover all of the burner ends. For those burners which it did cover [including the pilot light] it caused the burners to light properly.

For those burners who's ends were not covered, and who's gas could not be captured, they would NOT ignite simultaneously with the others.

As these burners WERE feeding gas into the combustion chamber, the gas "envelope" would spread until it reached the nearest flame ignition source, at which time the entire "bubble" of gas would ignite with a minor boom [actually a low energy explosion]. Flame would momentarily shoot out of the burner chamber opening, and from that point the furnace would operate normally until the next restart cycle.

Although there could be several causes, I suspect that the symptoms you describe are the result of DELAYED IGNITION of some or all of the main burners.

IF this is the problem, then the solution is to clean all the burners [including the burner outlet holes in the ignition ends of the burners], clean out the burner compartment, AND properly adjust the orientation of whatever system [you have to evaluate how it works from analysis of YOUR furnace] your furnace has to ensure all burners ignite as close to the same time as possible.

When operating properly, the ignition should be a smooth transition, burner by burner, from the pilot to the farthest burners. In other words. the ignition will "flow" from the pilot outward to each adjacent burner until the farthermost ends ignite last. This usually doesn't take more than one or two seconds at the most.

Unless you are an experienced handyman, and understand this analysis and instructions, I strongly suggest that you engage the services of a professional furnace technician.

Rheem gas furnace pilot lights, but no burners or fan


If the burners do not fully ignite, the sensor will shut the furnace down. The lack of sufficient burner flame is a gas valve or gas pressure problem within the valve.
Replacing the gas valve with the original one may get you going. I surely suggest a professional service company for safety reasons and a thorough inspection. A 20 year old furnace is past it's normal life span.

Furnace burners wait too long to come on


Sounds like the burners need to be removed from the furnace and cleaned thoroughlyto help with gas distribution if these are in-shot burners they look sort of like an air plane, they have a cross over tube on each side of each burner and if that is rusted up the gas will not distribute evenly from one burner to the next if the pilot and burners go off at the same time then it sounds like you may have some flame blow back maybe due to soot build up in the heat exchanger. Overall sounds like your furnace could use a good servicing
