Frididaire Gas Range-Faint Gas Odor

I have noticed a very faint natural gas odor coming from my Frigidaire range that seems to be coming from one of the burners when not in use. Our gas supplier, NYSEG, checked the range, as well as the connections in the basement and outside, but did not detect any leaks. The smell is very faint, and usually can only be noticed if you put your nose right next to the burner. This burner is also next to where the gas comes in to the burners, but again, no leak could be detected anywhere by the gas company. The smell also seem to be more noticeable a day or two after the range has been used. Service repair pros will not even look at the unit because no leak was found, nor did they offer any advice except to call the gas company again. The few suggestions from friends that I've gotten are that there could be a clog or something related to the ignitor, or that there is a faulty valve. I don't have any trouble lighting any of the burners. They are standard (not sealed) burners, and an electronic ignition. Any suggestions?

Hello andjela81. Welcome to the Gas Appliances topic and the Do-It-Yourself Web Site.

When dealing with appliance gas faintly smelled odors, there could be several problem possibilities and multiple locations to check.

Since the odor can be determined to be at one specific top burner valve, most likely the one used the most, the most likely cause for the odor is a lack of grease used between the internal core (valve) and the cone it is inserted into needs to be re-lubed.

There are some top burner valves that can be re-greased. Doing this solves the occasional gas passage from the valve to the burner or orifice which creates the occasional gas odor smell and may cause a hard turning valves to work freely again.

There are other types of top burner valves which cannot be successfully taken apart and put back together again. Those types must be replaced with new valves.

The re-grease-able type of valves {but not all} will have two tiny screws holding the valve core in place. This plate is located directly on top of the valve around the stem.

The main gas supply valve behind the stove must be turned off first. Then the two tiny screws, on the valve retaining plate, can be removed. Then simply lift the core out of the valve by holding onto the stem.

Clean the core and the bore it fits into with a cloth only. Use no cleaner, soap or WD-40! Apply a light weight grease {any type of light weight grease will do} sparingly to the core only.

Put the core back in exactly as you found it. Push it down to be sure it's seated. Reinstall the cover ring and install the two tiny screws, one on each end. Tighten the screws in carefully.

The valve now should look exactly as it did prior to removal. Rotate the valve on and off several times to spread the grease around and your done with this part.

Turn on the gas valve behind the stove and soap test for leaks both where you installed the core [on top of the valve] and at the orifice where the back of the burner sits on.

An alternative method to greasing is oiling. To perform this task, turn off the gas at the main gas supply line. Lift the stove top cover and remove the problem burner or burners.

Slip a soft automotive fuel line hose over the brass orifice. Hold the other end of the hose above the orifice and drop into the hose a few drops {6-10 drops or so} of 3 in 1 oil.

Then using a slight blow of air from your mouth, blow the oil in the hose into the valve core, while at the same time, using a pliers, gently pull upward on the valves stem and rotating it on and off.

TIPS:
Opening another top burner gas valve will allow the air your blowing in to flow out. It's always best to oil all the top burner valves while in the process.

When this procedure is done correctly, the oil will lube the valve, make it turn freely and help stop gas leakage to the burners when the valve is in the off position.

Should parts be needed, patronize our online sponsor, who's ad appears on this web page, for additional information and online parts sales.

Another source for original replacement parts is your local retail appliance parts store. Appliance parts dealers carry replacement parts for all appliances and are listed in the phone book under appliances.

For those who may not care to do this task, some natural gas utilities offer this service. Appliance dealer service agents do not offer this procedure. They must replace the entire valve in order to follow manufacturers policies.
