Wedgewood N8053A-2 Nat Gas Stove / Oven Calibration

Hello,

I've spent the past 4 weeks remodeling my mothers kitchen as a present to her as she recently lost both of her parents (floor to ceiling, the works..) And about the only thing I kept original was the Wedgewood stove because it's beautiful and helps maintain the 1920's "feel" of the place. (I'd guess the stove is 1950's)

The stove/oven is a Wedgewood N8053A-2. It's a wood burner/gas combo. It's got 4 burners on top (looks like space for 6, there are 2 plates above the wood burning part) and an oven and broiler below.. (also has the wood burner stuff off to the left and a second oven door just for the wood..) I would gladly provide pictures if it would help.

It seems that after shutting the gas off to move less than 2 feet from the wall (did NOT have to disconnect main gas line..) and work around it I've created a problem for myself..

I believe I've thrown the oven out of adjustment. When I turned the gas back on, checked for leaks I went to relight the 2 pilot lights.. 1 on top that feeds the 4 burners and 1 in the back of the oven. The burners on top worked right away but the oven just wouldn't come on..

I finally found the red reset (I saw this mentioned in another post), not knowing what I was looking for I tinkered with a few things before finding it.. But that made it work, I got the oven firing up again. But in trying to establish what was going on I had taken off the temperature adjustment knob, removed the valve shaft and I think by turning a screw that I now realize is the back screw for temperature adjustment at the knob I've knocked it out of calibration.. The oven comes on as soon as you start to turn the knob when it hits LOW but it stays on LOW as you spin the knob... all the way until you hit 550 degrees, at 550 you notice the flames start to grow and create some heat. 550 is the highest setting other than broil.. as you turn the knob the tiniest bit between these 2 settings (LOW --> Broil) it appears to sweep the whole range of gas output.

So in other words my question is does it sound like I threw things out of calibration? What screw/screws exactly are they and what is the best way to dial it in? (It worked sooooooo well before I did this..) Should I get an oven thermometer, pick a target like 400 degrees and then adjust as needed?

P.S. - After trying to calibrate/adjust rougly by turning the screw it now starts to build a bigger flame from LOW to 250, 350 and at about 400 seems to top out... 400 > BROIL visually looks like the same amount of flame coming out..

Thank you for listening!

Hello sfbayarea and Welcome to the Do It Yourself Web Site and to the Gas Appliances topic.

The 2 thermostats most often used on that brand during that time era was either a Robert-Shaw or a Wilcolater. Each had round bulb shaped T-Stat knobs.

When the knob was pulled off, there is a tiny screw with temperature + (plus) or - (minus) signs in the center of the stem with a pointer arrow. If you turned that center screw, then yes, the temperature will be off (out of adjustment) as I suspect you're describing in your post.

If the above is what you did, a recalibration would be required. Which isn't exactly a do it yourself task. However, the natural gas supplier will be able to due the calibration using an electronic (Fluke) temperature device.

Might be best or a good idea to call the gas company and inquire about an in home oven calibration.

Those styles and types of thermostats also have at least one or in some models two additional set screws. Each located slightly above center stem, one to the left and one to the right, of the center half circle center stem. Each controls gas flow.

One for the actuation (larger flame that heats the safety device) pilot flame. The other set screw controls the by-pass flame. By-pass flame allows the burner flames to adjust (large or small) as the temperature increases or decreases.

If any one or both of those set screws where turned or that center of the stem screw was turned, the condition you're describing will result.

Therefore, based upon what ever you did that is now causing a problem, all the adjustments may need to be reset. A process that requires each be done in the proper sequence and in the correct manner and adjustment amount or the correct end result (proper temperature) will not be obtained.

Best left to a tech with the proper skills, training and knowledge, IMO. Any further adjustments can or may only cause the condition to become more complex.

PG&E, Nat gas supplier in your area still provides in home services. Worth a call to request a recalibration, IMO.

simply the best advice possible

Brilliant!

However ironic it may seem, being told to have a professional complete the job in a forum called doityourself.com was simply the best advice possible.

Being an engineer / technician of a completely different study wasn't going to help me out in this situation, other than to know when to heed the advice of a specialist.

I called PG&E, (the roughly 30 minutes hold time was worth it) and explained the situation. They scheduled an appointment for a safety check and an oven recalibration next week at NO CHARGE. I guess I pay at a premium every month, so these kinds of services are effectively structured in my monthly bill already.. I just never knew..

Thanks a million! Beer 4U2

Hopefully you will get an oldtimer to show up. PG&E doesn't do full calibrations. They should however check minimum flame setting if possible. What city are you in?
