I've bought some stuff from RockAuto and they are everything you say they are. But we had a gift card for Amazon to use up.

Word.

The gas oven has been on the fritz. You could hear it the last several times we used it, cycling on and off every ten seconds or so. But there was a glow coming out from under the floor pan, so something was lit down there.

So I took the bottom floor pan of the oven off to watch the burner. It was definitely messed up. I figured it could be the igniter or the valve, or the pressure regulator. Or the control panel or the thermostat.

I did a little research and found that the igniter actually controls the valve. When the igniter heats up it starts drawing more current, and when it hits a magic number of amps, the valve opens and sends gas to the burner. So I dug out my multimeter and measured the current. I had read in one place that the magic number was 2.8 amps, an I read somewhere else that you should replace any igniter that draws fewer than 3.2 amps.

This guy was drawing 2.5 amps. So I think it's the igniter. That's good, because they are only $30 online. The valves are more like $150.

So now you know what an oven burner looks like just as the igniter is starting to fail.

I ordered one from Amazon with two-day shipping. Need to get this fixed this weekend before the holiday. It should be easy. Just remove a couple screws from the old igniter. Unplug the connecter, an swap in the new one.

well done glatt. boring pics of your success would be nice, but the actual victory is what matters most. I have every confidence in you.

glatt · 12-19-2014, 05:38 PM

Fewer than twenty minutes to install it, including putting the tools back. It works perfectly now.

BigV · 12-19-2014, 11:13 PM

Go, you Pro, you!

well done.

Well done!

Have I mentioned lately how much I freaking love the internet? First thing I did when I noticed this problem was open up our filing cabinet to pull out the owner's manual. There was NOTHING in there. Not even a parts list or schematic. Actually, that's not true. There was a circuit diagram, but no parts list. Going to the manufacturer's web page gave me a parts list but no details about how the parts work together. It could have been half a dozen faulty components causing this problem.

But going to two different appliance web forums and a separate appliance repair page gave me a great explanation of how the oven works and what measurements I had to take to see if the part was faulty or not.

20 years ago, I would have had to replace parts randomly or hire a repairman to probably replace parts randomly. But today I could ID the problem with certainty and order the damn part with expedited shipping for a fraction of the cost of a repairman and exponentially less than a new oven.

I love you, Internet.

I concur.

This could go in the Interesting links to share thread, but it is relevant here and now. I do the same thing as you described for lots of home and car repairs, and I've found this site (there are others like it) invaluable. Sometimes it's not actually broken, I just need to look up how something is "supposed" to work. Enjoy.

It's so damn easy to find good info on the net I've given up saving links for that kind of stuff.

Really? Good for you glatt. I jsut come here - via the internet - and ask you guys & gals. I assume you all go to other sites - via the internet - then reply with logical solutions sounding all smart & shit.

To answer the other question asked:

A switching power supply is one in which the incoming AC voltage is first converted into DC, then fed to a series of MOSFET switching transistors translate the DC into high freq AC which is then fed into a transformer with the output being returned to DC in more useful voltages.

The advantage of a Switched Mode Power Supply is that is is much more eficient and more versatile, able to provide either AC or DC outputs depending on the circuit involved. It is necessarily more complicted but has far less hysteresis and parasitic power loss than a comparable linear power supply and generates less heat.

That's as simple as I can put it without going all TW.

Thanks Pamela. I've been working on this much of this weekend, and it's taking a lot longer than I excepted. I'm a novice at soldering, and didn't realize how much there is in this. Over a hundred solder joints, and all those tiny wire pieces to cut and strip and twist. I'm improving though.

glatt · 01-19-2015, 05:35 PM

OK, so I made this pile of LED strips, and it took exactly 100 solder joints to do it. That's the most soldering I've ever done.

This was the first joint I soldered. Sad. I know.

I locked the exposure and white balance of the camera and took a before shot with halogens.
