Our 12year old Amana gas oven has a gas leak smell when we turn the oven on. The ignitor starts up and lights the gas, the oven heats up, but still smells of gas. We turn it off of course. I wonder if it is the ignitor. Also, two of the top burners will no longer ignite, they can be lite by a match. I would say time for another range but it's in great shape otherwise. Can these problems be fixed?
Staunch has no idea what he is talking about. It has nothing to do with the igniter, or it would fire up at all. Since you are saying that your oven does ignite and heat up, it is the internal gas valve that is the problem.
The way all recent (20 year at least) are designed, the gas valve internally can not open unless the igniter is working, for obvious reasons ... boom! The igniter circuit allows the gas valve to open, once it detects that the igniter is ready to "ignite" a gas flow. BUT, the valve can be bad in the AMOUNT of gas being delivered. Your's is allowing too much gas, more than can be burned, hence the smell.
DON'T use the oven until you have a qualitifed tech come out and replace the valve. It is very dangerous for you to do it yourself.
If you only get a gas smell when you turn on the oven then it is not likely you have a gas leak- the ignitor resistance drops as it heats up and when it drops low enough the main gas valve opens and the gas ignites from the hot ignitor. If however you have a gas smell all the time and have to shut off the main gas valve (at the flex line) then you have a problem. Not sure where you are located but here in the bay area (CA) our local utility company will come out and do a leak check for you gratis. As for the burners not lighting- do you see a spark at the burner you are trying to light? If so, the burner is dirty. If you don't here a clicking sound when you turn the know the igniter switch is probably bad.

Hello- Ignitors may 'light' yet not reach proper resistance and temperature, causing improper gas flow past valve. If resistance is below 4 ohms, ignitor is bad. Part is 40-75$ at local app. parts store. Fairly easy to replace. Hope this helps. -Thanks- ED
Find the bake ignitor (you may need to remove bottom drawer or oven cavity floor to get to the ignitor). Turn on the bake. If the bake ignitor comes on (starts glowing after a few seconds) - check the amperage on the bake ignitor wires when it's on. If the ignitor is a round style - amperage should be 2.5-3A, if the ignitor is rectangular - 3 - 3.6A. If less than 2.5A or 3A respectively - replace ignitor. If the ignitor does not come on - check the voltage on the ignitor, should be the line voltage 110-120v AC. If there is a line voltage on the ignitor and it's not coming on - replace. Ignitor part numbers for round style ones: 4342528, WB2X9154, SGR403, 5304401265; rectangular styles: 12400035, WB13K21, WB2X9998, SGR412, NR020, 5303935066, 814269, 9753108. Ignitors of the same shape (i.e. rectangular) are interchangeable, if you can splice the wires.
When you turn the thermostat on your range on it sends 120 volts to the
bake valve and ignitor. The bake valve and ignitor are wired in series
and the ignitor draws all the current and heats up. As the ignitor
heats its resistance changes and when it is cherry red the current
switches to the gas valve and it opens. The amp draw on the ignitor
needs to be 3.2-3.6 amps for the gas valve to open. The gas valve has
gas to it at all times. The gas valve should open within 40 seconds after the ignitor starts to glow. If
the ignitor is glowing red and the gas valve doesn’t open the ignitor
is usually the problem. Sometimes the ignitor will glow red but the
resistance doesn’t change and the gas valve doesn’t draw the current.
This is not a do it your selfer!
Thank You For trusting us with your question Please remember to leave a solved rating before you leave!
slow to preheat??? long cooking times??? smell gas while in operation???. all signs of a bad oven ignitor retails for about 60-65. easy enough to replace reomve the lower panle of the oven itself and you'll see the ignitor right there 2 ***** mount that to the bake bar and pull it out, unplug the wire harness, plug in the new one and remount.Start baking
yea sounds like you have a bad oven ignitor, tell tale signs are not heating past warm, smells gas, too long to cook, popping noises while cooking. Id replace that ignitor. Although it might appear to "glow" not glowing strong enough
