Thermodor model #RDFS30RS left forward burner won' light. Ignitor works but no gas.

Since it is gas, you need to find out if the ignitor is coming on to ignite the gas (if you have gas getting to the burners). If you have gas, but the ignitor is not coming on, then you have to determine if the electronic contol is sending a signal for the ignitor to ignite. The most likely cause is the ignitor

It sounds like there may be an issue with the ignitor switch for the large burner. Here are a few things you can try to troubleshoot the issue:

1. Clean the ignitor: Sometimes the ignitor can become dirty, which can prevent it from working properly. Try cleaning the ignitor with a soft brush or cloth to see if that helps.
2. Check the wiring: Make sure the wiring for the large burner is properly connected and not damaged. If you're not comfortable working with wiring, it's best to call a professional.
3. Replace the ignitor switch: If cleaning the ignitor and checking the wiring doesn't help, it's possible that the ignitor switch for the large burner is faulty and needs to be replaced. You can find replacement parts online or through a professional repair service.
4. Call a professional: If you're not comfortable troubleshooting or making repairs yourself, it's best to call a professional appliance repair service to diagnose and fix the iss

Hi,
I need more information to help you, first of all, to the bast of my knowledge I thought all there units were light but ignitors not pilots. I need a model number to verify. Also if the ignitor comes on just because it glows does not mean it is strong enough to open the safety valve and allow gas to enter the burner. I use a meter to determine that issue, it needs to be 3.2 to 3.6 amps to open, if ignitor is running at 2.8 amps it may work sometimes, if lower, it won't work at all just glow.
I would need a model number to get you more information, looking forward to assisting you further...

When increasing the temp. on a gas range the oven's burners do not increase flame size as the cooktop burners do. It just keeps the burner lighted for a longer amount of time.

First if you can see the burners do they light within about a min. or less. If no you probably have bad igniters which are not lighting the burners as quickly as they should or they are "opening up" (stops working) when they get too hot. In this case replacement of the igniters should solve the problem.

Second if it lights quickly but still takes a while to heat; you want to look at the burners to ensure that the flames are down both sides of the burner tube and not dancing around too much. If only part of the two sides of the burner tubes are lighted then a pluged orifice or burner tube is the most likely cause. Once cleaned it should work fine.

As with anything mechanical there are numurous possiblities for something not working correctly and above are the two most popular reasons that come to my mind.

next time send the brand name and model number so i can look up your machine,if it's a gas stove most likely it will be a bad ignitor,even if the ignitor glows it still could be bad,if the flame doesn't ignite and the ignitor is glowing change it out,if it isn't glowing pull out the ignitor and check it with a meter,common problem.

You just need a new gas valve. This is a simple repair for you and you can save a lot of money by repairing it yourself.

there is a spark ignition in the middle between the front and back burners....one for the left side and one on the right side. When it was cleaned i bet that the spark ignitor was slightly bent towards the front burner...now the gap is too big to fire the rear burner...the ignitor is very similar as the spark made in those push down lighters. so its safe to play around and adjust them as needed to make them work...Go ahead and take it apart and tinker with adjusting it...until you get both front and rear burners running again the way it was before.( peek at the otherside as a reference and try to make it match)
I hope this helps you out a little bit 8-)

The Viking manual says that an ignitor that continues to try to light even after the burner has been lit indicates improper grounding, and that an electrician should be consulted.

Perhaps you could try to replace the ignitor, and see if that fixes the problem?

I have a similar age, 6-burner 36" rangetop.

All my ignitors spark when I turn one of them on. I'v been told it is normal. I had a problem before and the tech that replace the ignitor said the issues is with alignment. Try to rotate the burner a bit left or right and see if it fixes it.

I had a problem in which only one burner refused to light with the electronic ignition, even though the same ignitor (they are shared) would light the rear burner on the same side, and the problem burner would light with a match. On inspection, the spark occurs at a central point and there is a tube which apparently leads gas from each burner to the ignitor. There are two groupings of 3 holes each on the sloping part of each burner, facing toward the ignitor. After lighting both burners (the front one with a match), I saw that the lower group of 3 holes had tiny flames on the burner that worked properly, but not on the other. I carefully cleaned each of these holes with a small pin, and the problem appears to be solved.
