Tappan Gas Range Won't Light

14 posts in this topic

The model # on my range is tgb500ccb-2 and just started failing to light yesterday. The igniter glows if you turn the heat dial to a high (didn't try to figure out how high I must turn the dial) but no gas exits the burner. With the igniter glowing, I used my bbq lighter to try to light the burners but no go due to no gas. How do I determine which component is defective? I have a dvm and know how to use it if someone can tell me what to check.

Thanks,

Wayne

I just now found the page discussing 3.2 to 3.6 amps for the igniter. I'll have to find an amp probe but maybe that's the culprit even tho it's glowing.

If you have continuity between the 2 terminals on the safety valve after removing the 2 wires, after unplugging the range, your ignitor has gotten too weak to open the gas valve.  Holding your bbq thingie to the burner will do nothing except light the way to see better in the dark cavity of the chamber.

I just now checked the amp draw on the line from the gas valve to the igniter and found it only had 2.77 amps. Given this, do I still need to check continuity on the gas valve terminals? It's a built-in and the AC connection is behind the unit....I know, I know....I'm lazy.

P.S. What is the pt # for the igniter and what would my cost be?

I am having problems with my Tappan over. The burners on top of my stove work fine, but my oven won't light. Is this the same part that needs to be replaced?

I am certainly not the fixit master but if I were you, here's what I'd do to find out. This is totally based upon my recent experience.

1.  Unplug AC power to oven

2.  Unplug both wires going to gas valve

3.  Check continuity between the two connections on the valve..should have continuity.

     If not most likely a bad valve.

4.  If continuity OK on valve, put connectors back on valve.

5.  Plug AC power back in.

6.  Turn oven on and check amp draw on line from ignitor to valve.  If out of spec with

      your style of ignitor,  highly suspect ignitor even if ignitor is glowing.

In my case, it was the ignitor.

Have a Tappan gas oven Model # 30-3352-23/02 from about 1990.  I'm pretty certain I need a new igniter for my Tappan oven.

My problem is that the oven sometimes will not light, or it may take a very long time to light, even though the igniter glows when it is turned on.  When the oven does light, the temperature usually fluctuates, and rarely reaches the desired temperature.  Oddly, when the range burners are lit, the oven temperature (once lit) remains relatively close to the desired temperature, but usually 25-50 degrees lower.

My question is, to replace the igniter, must you pull out oven, lay it on it's back & disconnect AC prior to safely replacing igniter?  I don't think I can fit into the broiler section to replace igniter in its current location!

Thanks

Not sure if your Tappan is the same as mine due to the difference in model numbers but certainly would suggest that you disconnect AC from oven before troubleshooting. 

I removed the broiler by just sliding it out and lifting to remove.  Once this was done, I had enough room to replace the ignitor without completely removing the oven from the wall.

if your ignitor comes on and is a burnt orange color its bad ,it should be so bright its hard to look at

I have the same problem you discribe with my Tappan Model #TGF356BCWB . I checked the current from the ignitor to the valve and have 4.1A. So I gave the vavle a tap, and the oven fired up right away. This will be the second valve for this oven. I replaced it once already in 2003. Maybe that why it's called a Tappan, cause it seems you have to do that to get the oven to work.:? Unless 4.1A is too much and I have a different problem.
