This range had two complaints. One was that the gas grill module wouldn’t ignite.

Here’s the patented Samurai kata for troubleshooting heating element problems in electric ranges:
Unplug the range, remove the element and detach one of the power wires from the element (doesn’t matter which one). Secure that wire so that it doesn’t touch anything– alligator clips can be helpful here. Next, measure the resistance of [...]

Lots of these old GE XL44 model family of ranges out there in use today. At some point, you’ll need to run diagnostic tests on the old girl. Could be an error code in the display, incessant beeping, or it just ain’t working right for some reason. In any case, putting the [...]

GE strikes again! This time, they’re recalling a quarter of a million wall ovens sold under the GE, GE Profile, Monogram and Kenmore labels.

More trouble with cheesy electronics in appliances. This time, it’s the Whirlpool-built (includes KitchenAid) built-in combination microwave ovens.
In this particular inconvenience, error code “door” appears in the display and the microwave oven shuts down in mid-cycle. When restarted, the microwave will shut down immediately again and show the “door” error code.

Removing the control panel on a wall oven can be tricky. On some brands, such as the Frigidaire, you need to actually remove the walloven from the cabinet just to remove the control panel. Why they design it like this, I’ll never understand. Nevertheless, this is but one of a plethora of [...]

Within the the world of pilot ignition ovens, two types of pilot flame systems [...]

If your gas oven isn’t firing up, start your diagnosis by checking the ignitor for the proper current draw. “Uh, do what?” you ax, with glazed eyes. Don’t be intimidated by techie-sounding procedures. This is simple stuff– if you can fog a mirror, you can measure current draw. This article explains [...]

My maytag gas oven is taking longer to pre-heat. What do I check?
You need a new ignitor, such as the one shown here in the thumbhail pic. Click it to git it, install it and you’re good to go. Slam dunk.

So, you pulled the door off your Thermador range because you and your buddy were doing shots of cheap vodka and, well, it seemed like a good idea at the time. Or maybe you had another reason that sounds almost as good as that one. Whatever. But now, you can’t figger out [...]
