hot surface ignitors are notorious for failing or getting "weak" and not draw enough amperage ( 3.2 - 3.6 amps ).... replacing both ignitors is always a good idea to start out with as the gas bi-metal valves don't fail very often. Ignitors can be replaced relatively easily ( with the POWER OFF ).... replacement ignitors can be ordered here, im sure..Ceramic bases should be similar / exact size and mounting bracket should be as close to exactly the same as original as possible!!!
It should glow almost a bright white. If its just an orange glow then replace the ignitor. Its probably just weak. If its weak it will not allow enough current to flow through it to open the gas valve. Good luck _MJ_
Sound`s to me you need a new hot surface ignitor. Sorry to hear you may have changed the valve & regulator for nothing, but that happen`s quite often when you get the symptom`s you`ve described, I`ve even seen tech`s. do it. The reality is 9 times out of 10 when a hot surface ignition gas/lpg oven won`t light it is the ignitor.
Pick up part number 74007498 for approx. $40 and you`ll be cooking.
Hope that help`s. If so please take a second and rate the solution I provided here at fixya for you.
Oven ignitors are not the "clicking" variety - they use a hot surface ignitor and "feed through" to a current sensing gas valve - in short, if the ignitor is going bad, then the gas valve won't open (safety). Try replacing the HSI in the bottom of your oven - do an online search and match up model and serial of your unit to the part. Be careful no to touch or break the new ignitor - VERY FRAGILE!!!
Sounding like your hot surface ignitor is getting bad. What I would like for you to do is open the oven and take the bottom panel off. This is so you can see the hot surface ignitor. Turn the oven on and look at the hot surface ignitor it is down on the bottom right next to the burner assembly. Does it start to glow and turn cherry red? This ignitor isn't too hard to replace couple of small screws and two wires. Will have to cut the wires so disconnect the unit from the 120 volt plug. Now if it starts to glow and get cherry red hot then the gas valve is sticking and it is the one going bad. That is a little tougher to replace. Turn the gas off at the source and get your wrenches unscrew the gas valve small space so if you want remove the door by just pulling it off the hinges.
If unit is old and you don't like it anyway maybe santa would be good
to you and replace the stove oven. The gas valve is about 60 bucks or
so and hot surface is about 20 bucks. let me know how it turns out.. ken
there is continuity, you can tell that by the glowing ignitor, althoug otslooks like its glowing red hot, it need to pull a certain amperage to open the valve.i would reccomned replacing the ignitor.with 99.99 percent certainty
The control sends voltage down to the ignitor, the ignitor glows red, when and if the ignitor gets hot enough it opens the gas valsve to let gas in which is then lit by the ignitor.
If ignitor glows either the ignitor is bad or the oven valve
If the ignitor does not glow then either the ignitor is broken, the control is not sending voltage down, or the oven valve is bad and not sending voltage to the ignitor.
In most cases it is the ignitor which is the cheapest of the three parts
