Question about Microwave Ovens

2 Answers

No gas odor at all when the range is not in use. If I turn on any one of the four burners (all light quickly and have blue flames) I smell gas and it gets worse the longer the burner is on. The same goes for the oven/broiler compartment. If I turn on the oven to preheat it starts normally and the heat ramps up but again I smell gas. If I turn everything off the smell will disapate completely. I checked the connections from the hard pipe to the range with a soapy solution. No bubbling. I aslo put the solution on the ouput of the main gas valve at the base of the range and again no bubbling? What could be causing this problem? I am very confused. The only common component to the oven/burners is the main gas valve. Please help.

If all the burners and oven are burning good and strong, that is a good sign. Check that the gas valve is not leaking or that none of the tubes are leaking or have any tiny pin holes.

    If pin holes were present in any of the tubes or main gas valve wouldn't they leak even if the burners were off? I

    the oven gas control is directly behind the oven
    temperature control knob and there is a pipe from the oven regulator
    down to the burner. If there happens to be a leak on the pipe from the
    regulator to the burner it would leak raw gas as soon as the oven
    regulator was turned on. Gas is basically heavier than air, which means
    the leaking gas could collect under the rangetop and inside the range
    cabinet while the burner is on.
    There is a vent from the oven through the top of
    the range and it is possible that what you are smelling is normal
    combustion exhaust from the burner.

    Also,

    Ignitors
    do age and will eventually generate less heat than they normally
    should. When this happens they can still allow marginally correct
    current to flow to the oven gas valve for it to open but not get quite
    hot enough to ignite the gas burner immediately. When this occurs, gas
    released into the oven can result in a gas smell or sometimes even build
    up to the point where when finally ignited, the extra amount of gas lit
    can cause a small explosion inside the oven.


    In the latter case,
    the oven should be removed from use until the condition can be looked
    into and corrected. DO NOT continue to use a gas appliance in such a
    condition!

    I have a Whirlpool 465 Range and the oven temperature control and ingnition for the oven burner are electronic while the stove top burner controls are all manual and are tapped off the main manifold. Why do you think I would get a gas smell using either the oven or an individual burner??? I am totally lost. The only common component to both is the main gas valve unless I am missing something? Have you ever experienced this problem before.

    In the last house I owned, I had an oven do that the entire 3 years I lived there. It was even a new oven. I looked at it, I had 3 repair companies and 2 other fellow handyman look at and found nothing! It worked well but smelled up a bit, but nothing else ever happened. I used it daily for 3 years like that. I spoke to the new owners on a couple occasions who where asking about it, they too had numerous companies come and look and found nothing as well.

  • williambecha Jul 29, 2010

    So your recommendation is if I cannot detect a leak, which I can't and can live with the odor than it is probabley safe to use it in its current condition?



    Is there anything else I should check out?

  • Nate Stansfield
    Nate Stansfield Jul 29, 2010

    Not anything further from my experience. If gas valve is not leaking, no tubes are leaking, and the smell doesn't fill up your entire house where it would be hazerdous, you should have no problems. Others I'm sure will tell you the same exact thing as they did for me as well.

Hello,

If you can breathe easily and the smell of gas is not overpowering and you cannot hear a loud sound of escaping gas, check the stove for burners that are on but not burning. Turn all knobs to off.

Look for an oven control knob. It should be in the off position. Turn the control knob to off.

Some clothes dryers are gas operated. If this is the case, turn the dryer control knob to off or press the off button. If it is not clear that the dryer is operated by gas do not operate the controls.

Most all propane and natural gas supply companies will come to a residence and test for gas leaks. They will not perform the repair but they will identify the source of the gas leak. So call them.

Gas leaks, even very small gas leaks, will not fix themselves. Always contact the gas company for help in locating the leak and use an experienced repair person to repair the leak.

Safe your life and property by calling an experience repairer.

Thanks.

    All knobs on range for the burners not in use are OFF.

    The oven is not controlled by a manual valve. It is elctronic.

    Do you have any idea of what component in the range that could cause this. Please explain how the main gas valve works. Could it be faulty?

  • Rahman Rufai Jul 30, 2010

    Hi

    Gas valves are actually very simple to understand. Once you understand
    how they work, it'll almost seem embarrassing to have to explain how
    they work cuz they're so simple.



    When you look at a gas valve, imagine two valves in series.



    The gas port where the tube to the pilot light connects is between the
    two valves, so that gas can flow to the pilot light as long as the first
    valve, or "safety" valve is open. If the second valve, or "main" valve
    is open, it can also flow to the burner trays.



    Both valves are operated by electromagnets. The electric power to hold
    the first valve open, and therefore allow gas flow to the pilot light
    comes from the thermocouple or thermopile immersed in the pilot light
    flame. The thermocouple or thermopile generates electricity from the
    heat of the pilot light flame.



    So, if the pilot light flame goes out, then the voltage to hold the
    safety electromagnetic valve open is lost and the safety valve closes,
    thereby shutting off gas flow completely, including the gas flow to the
    pilot light.



    The gas valve needs to be replace.

    T hanks.

Hi,
Here is a test you can use to check the ignitors, Ignitor test. I also would like to you turn the thermostat knob slowly from the off position, When do you hear the click in the knob?

Good Luck

I clean the burners and the ignite it is not working if i used a lighter the back tow burners will turn on but not the front ones


Sometimes when we clean the burners we get some debris or gunk into the gas outlets. I always take a toothpick and clean out the gas openings. Be very careful that you don't break the toothpick off in the opening. Once you've done this, use a lighter at the burner and turn on the gas. You should have a flame. Let the flame burn for about 5 minutes to burn off any more "gunk" that may be in there. Also, if your burners have covers, make sure they are in place before you light the burner.
Depending on the age of your range, you might need to clean around the igniter. Some are concealed and you can't reach them. Those that are not concealed can be cleaned by wiping with a soft, dry cloth.
I hope these suggestions help you get your range working again. If they do, please come back to Fixya and rate my advice!

Just got this RV. I can't get the range to light. Is there a shut-off valve that I just don't know about???


There may be a valve under the cook top or under the stove. You will of course have to look. There is really no 'standard' or requriement for a valve to be there.

Another reason for this kind of problem is spiders. Spiders love the smell of propane. If you are sure your gas is ON and you do have fuel in the tanks and the tanks are on, (always have the valves of both tanks open all the time (consistent with the highway regulations in your area) and the selecter lever is pointed left or right (never n the middle!)!) remove each burner and blow it out with compressed air. Simply blow it out with your breath or get some 'canned air' at the computer store.

Does your frig operate on gas? You can force it to run on gas (to check it) by disconnecting the 115 Volts; simply disconnect your main cord. Will your frig come on? How about your heater? and your hot water heater?

YOU MUST have a 12 volt battery connected to your RV - a "HOUSE" battery not a "VEHCLE" battery. Everything in your RV runs on 12 volts except the obvious 115 items like the AC and the microwave and the TV. Do not rely on the 15 amp "converter' to supply all your 12 power requirements which often exceed the ability of your converter to provide.

If you stil have no luck, I suggest you turn off the tanks and disconnect the gas line from the stove. Have an associate turn on the tanks while you observe (smell, watch, listen) the unattached pipe. If you hear, smell or see gas, have them turn it off immediately. Reconnect the pipe and test for gas tightness (use a soap water misture. Bubbles = leak. Next step will be to consider the burner controls. This may not be a DIY job. NOTE: Propane is heavy and will sink to the floor. Make sure you have no open lights or flames when you perform the test above and let the gas excape out the open door.

You don't say how old the RV is and given the thousands of makes and models it really doesn't make a lot of difference. Unlike cars and trucks, manufactures of RV's install what they have subject to many substitutions through out the model year. Typically, newer RVs have electronic ignitions while some older RVs have pilots (NOTE: pilots burn precious limited fuel and generate unnecessary heat) and many are simple match light burners.

I hope I have shed a little light on your trouble and you are able to resolve this problem. If you cannot, of course, you will have to have reservations for supper which will make you or your spouse happy.

I hope you enjoy your camper this summer. Thank you for your interest in FixYa.com and please come again.

I have a maytag super capacity plus stove and need to adjust the air mix for the burners. How to do it? Please help thanks


Open the top of the range. I believe there are a couple of spring clips in the front between the range top and the top of the door. Not sure on the Maytag. However, when you get the lid up, (it should be hinged at the back), set the burner pieces back on. (These burner pieces HAVE to be there or you'll just have a blowtorch pointing up!) You'll see that going to every burner there is a tube to carry the gas. on the side of every tube there will be an adjustable, sliding air vent. They are usually held in position by a set screw. Loosen the set screw. Light the burner and carefully slide the vent closed or open to adjust how much air is being brought into the mix. If the flame is way too high and or orange in color....you have too much air. You want as much flame as possible on high without the flame being orange or white-ish. Once you get the flame the way you like it, tighten the set screw back. Hope this helps.

When stove is on a yellowish orange flame comes from burner.This has not occured until now. We own this viking oven for about 10 yrs without any issue whatso ever. Can you help to resolve this issue


You need to replace the burner if you want blue flame. Since its 10 years old, it's about time to replace the burner with similar size and shape. Old burner have big hole causing yellowish flame compare to new one.
I hope I solve your problem.

Do you know what the average electric cooktop lifespan is? We have a Kenmore that is 9 years old and working fine. However, we are in the midst of a renovation and are wondering if it wouldn't be wise to...


The life span of the range depends on it's use or abuse.... Common issues are burners and the connections that the burner plugs into. These are not hard to change out.... There is nothing that can make the stove useless, if you keep after it. Newer units do a better job of retaining the heat within the unit, oven wise....Which is nice.

A gas range is certainly nicer, so they say. It is faster, but has one odd issue: if you boil water over, you can put out the flame and have raw gas running in. Most work this way, expensive units have thermal sensors that would turn off the gas flow in flame out condition....

My wife loves her gas range....

You should try cleaning the orifice first. Actually before you do that, if you can see the flames on the oven this simple check will determine a cleaning. Turn oven on and look at the flame, if you have propane it should be light blue at the base a little darker blue in the middle and have a little orange tip. If you have natural gas it should be almost all blue with maybe a slight tint of yellow in the center of the flame. If the flame looks like it is almost all orange. It needs to be cleaned. I can assist with the cleaning also, but confirm with this test first. Please rate answer accordingly!! Thank you

When one of the gas hobs is on ,it does not burn with a blue flame but a more yellow one .also black soot forms under the burner plate.it is on lpg


Have to adjust the piolot lights for the amount of gas coming out. U have too much gas coming out(yellow flame). On older gas ranges, there was a small screw between the piolot light & burners that had to be adjusted. (if this is a older model) have to turn the screw just a little at a time, till ur flame returns to blue on ur burners. Hope this helps.
