It's been a long time since I thought about this. I was having an issue recently that I think was probably just water in an igniter (overflow or from a pot put back on the stove to dry after cleaning). I'd been meaning to check back and remind myself what I did and maybe update if I change something out. I did notice that the screws attaching the igniters were pretty corroded. That may have been a bad material choice on my part. My quick and dirty troubleshooting would be to trade igniters from a working burner to a nonworking burner to decide between module and igniter. If the same burner still doesn't work, you might also check out the wiring to see if it's been pinched or otherwise has a problem. That's my mute-the-work-conference-call-and-type-real-quick response.

I suggest speaking to a conservator who specializes in photographs. They may be able to recommend a method or product to fix the slides. If the slides can not be fixed, you can scan them and then fix the scans with photo editing software. I know it will not save the slides, but at least you will have the photos. And whatever you do, get them scanned before you or anyone else starts trying to clean them. Which brings me to the scanning: If you have a lot of photos that need to be scanned, it may be more cost effective for you to buy a scanner and do it yourself. You can get a very good scanner relatively cheaply and they are easy to use. You can get free photo editing software (Gimp) that has all the necessary features you need in order to fix the inevitable colour shifts and scratches in the photos, or if money is not an issue, you can get Photoshop or similar software.

Walstreet Journal article: Trying Out Photo-Transfer Services Benefits of Saving Family Pictures Can Be Worth Risk By SUZANNE BARLYN March 1, 2007 (See Corrections & Amplifications item below.) Slides these days are about as useful as eight-track tapes. But that's changing now with the spread of digital-transfer services available through national retailers and on the Web. Such services convert slides, photos, videos, and negatives to DVDs and CDs. We worried, though, about sending our family treasures to unknown technicians. To find out if our fears were justified, we tested five digital-transfer services. We found the benefit of reliving our family history -- in funky hues that are characteristic of 1960s photography -- was usually worth the risk. A stained photo circa 1943 (left) was cropped and restored by a transfer service. We learned it is important to organize old photos in advance, since the ordering process is confusing. We also benefited from speaking with phone representatives at mail-in services, instead of store clerks who weren't as knowledgeable. They advised us on scanning resolutions (measured dots per square inch, or dpi). We found that increasing the resolution costs more. Scanning slides at a minimum of 2000 dpi and photos at 600 dpi is generally adequate. A telephone representative from Brite Pix in Miami answered our questions about scanning resolution. The company alerted us via email when our order arrived for processing and sent a price for our restoration ($30). We received CDs of our slides and old photos and contact sheets (75-cents per page) three weeks later. But we were surprised when the completed order, including original slides and old photos arrived from Costa Rica. A Brite Pix manager said labor costs are cheaper there, but we weren't aware that our pictures would be making a second journey out of the country. Our digital images from Digital Memories Photo & Video in Orient, Ohio, were worth the trouble of an eight-page order form. We received follow-up questions via email and an estimate for digital photo restoration (in our case, $45). Our images arrived on CDs in separately labeled cases. A custom DVD slide show proved worth the money as we relived the 1970s to our favorite classic tunes. DigMyPics! in Mesa, Ariz., delivered prompt service and email that alleviated concerns about our photos' whereabouts. But our own haste in reading the instructions meant ordering a JPEG DVD instead of a DVD video. (JPEG files don't play continuously. We had to click "play" to view each one). We would have understood the difference if we called customer service ahead of time. But the reasonable price and processing time were good reasons to order again several months later. At Wal-Mart, two clerks assisted customers while operating photo machinery. We wanted our slides scanned and burned onto CD. But after waiting 10 minutes, we learned the CD burner wasn't working. We ordered prints instead, which wouldn't be nearly as versatile as digital images. The pictures were fuzzy and some were printed backward. We returned to transfer a video to DVD and restore a family photo. Our DVD worked well. The restoration was lovely, but pictured another customer's family. Fortunately, a technician scanned our original photo and returned it when we placed the order. A manager was supposed to call about the mix-up, but never did. A Wal-Mart spokesperson offered free reprocessing. We tried YesVideo, a service available via drop-off points at pharmacies and discount stores. An Eckerd clerk didn't know the service existed. We eventually spoke to a manager who vaguely recalled the service. We felt uneasy about leaving our slides and video, and with good cause. They arrived at YesVideo a month later, but we don't know where they were during that time. We received our completed order six weeks after drop-off. Eckerd discounted our order by 25%. A spokesperson said the employees would be aware of YesVideo in the future. * * * COMPANY/WEB SITE PRICE PER SLIDE SCAN/ PRICE PER PHOTO SCAN* APPROX.

@r, I thought I would chime in here to just say that I don’t think you are “obsessing“ at all regarding the use of knobs in this case. One of the most crucial variables in any kind of industrial design is the way we interface or interact with whatever the product is. Most of us utilize capacitive touch controls or infrared type touch controls on a constant basis with everything from iPads, smart phones, as well as any number of house appliances. But I would suggest that your instinct regarding cooktop or rangetop controls makes a lot of sense. Consider the difference in using a wall oven versus a cooktop. Most cooks in the kitchen can get the opportunity to wipe their hands in order to use touch capacitive controls on a wall oven. Of course, the case could be made that turning a simple dial, can be more intuitive, then going through a series of menus to get to where you want to go, since in the end, the mission of the wall oven has not really changed very much since our grandparents time which is essentially to bake the cake or roast the chicken. The reason I suspect that cook tops and range tops, as well as ranges are a particularly good candidate for knobs is due to the fact that the controls are often placed on a horizontal plane. Many people, especially those who are new to induction appliances for example, have learned a hard lesson as the very sensitive touch controls do not always take kindly to steam, water, droplets, and oil or gravy splatters. It is not hard to imagine why this is problematic because if you put any of these liquids on top of your smart phone screen, you would discover that the touch controls that works so beautifully such as the ones I’m using right now on my iPhone to create this post do not take kindly to having these substances on top of them. There are lots of examples of folks who have touch capacitive controls on these horizontal locations where the entire appliance is either shut down or thrown off its game. Of course, the majority of modern products that have knobs do not use the analog/mechanical controls of knobs of the past, but are in fact, “knobs“ that interface with micro control boards behind them. Still, there is an entire field of design that studies user interaction, and I do think that, at least, in some instances, such as with cooktops, knobs actually, do make a lot of sense. One can certainly debate where the best location for those knobs would be to avoid getting splatters on them since Cleaning knobs is not exactly, a fun time for most folks. Some people would assume that installing Touch Sensitive controls in all sorts of consumer products that once used knobs, levers, and buttons, is simply a design trend, and I’m sure there is truth to that. But a little voice inside also suggests to me, that one of the reasons they have moved away from knobs and especially the electromechanical kinds used in the past, is due to the cost of manufacturing. I do not have a data set to support this theory, but if you consider the labour and the bewildering amount of copper wiring that went into something such as a 1950 electric stove, some of which had lots of extra features, you can begin to imagine the cost savings of having a micro “motherboard“ taking the place of all that complex analogue electrical structure. I truly enjoy all of the benefits and possibilities that I have with my smart phone, laptop, iPads, etc. But I do think your instincts for knobs are not without merit, because sometimes, appliance designers attempt to answer questions that no one ever asked. My two. Cents 🤔.
