I have a Chambers GSU-42-E-1 gas cooktop from 1981 and it’s time to replace the spark module (it still fires but takes 45s or more to charge). The original spark module part number was CC70167 (I still have the Installation Guide & Parts List). I took the front panel off and could see the spark module in the back left corner, but couldn’t see how to get there. I’m guessing the whole stainless steel top lifts up somehow, but I don’t want to go blithely unscrewing things in a 30 yo appliance, that never ends well. Is there a service manual for this cooktop, or any tips on how to get at the module. Also, does anyone knows if there’s a replacement igniter that matches the original.
@ mb60…your outcome?
Chambers GSU-33-E-1 installed circa mid '80’s. Spark never seemed to work correctly as I recall.
After an hour or so online checking this and that forum, I’m thinking the spark module is Y-54052-KIT 2+0 (Robert Shaw 5303912606 GAS RANGE SPARK MODULE KENMORE FRIGIDAIRE…made by invensys now). Will have to pop open unit on my next visit to the house (@ my sisters place) to extract for further investigation.
My first inclination is to check grounding and spark circuit path for corrosion or bad connections. Also to inspect burners and see if any orfices are clogged that would prevent spark, or gas, from meeting.

Techman_hou: It looks like you are familiar with these old Chambers cooktops. I have a problem with the Valves on my Chambers cooktop–which I posted a short while ago. The valve on my cooktop looks the same–would really like to get the valves replaced or repaired. Any help would be greatly appreciated. nankivell@earthlink.net

nankivell,
I am not so much familiar with the Chambers stove tops as just very detail oriented. I work on CNC machinery, and know that pictures and details can mean the world of difference in getting the right answer. That being said, no one has responded to any requests (this forum or others) as to where to get Chambers 70’s & 80’s era vintage parts. I did find a handful of ‘discontinued’ burners available that looked similar, but were not listed as Chambers items. I will have to look again to see if the burners are still available, but I need to fabricate the Left Front gas feed tube and flange as well. I was able to locate a few used units for sale, in the $500 price range, but that was more than I wished to put out to replace the valves.
I might suggest, only if you are highly confident in you DIY’er skills, that you visit an appliance store (new or used) and find a newer model stove to see if you can adapt or retrofit the newer valve parts to fit your Chambers stove. The guts of the igniter/burner/valve assembly may be slightly different, but if you can get all to align up, then it should work. This may entail shortening or extending some piping or wiring.
I will look some more. my project is my sisters stove top and been on the back burner so to speak.
Try KitchenAid for similar components…From what I recall KitchenAid purchased Chambers in 1988 and let the name go and absorbed the line of products. A similar gas cooktop (do your own research to verify) is Kitchenaid KGCS100SWH2, a 30 inch cooktop with burners that look a lot like the 4 and 6 Daisy Power burners.
Several caveats to restoring an older unit is that (in some jurisdictions) the code has changed to require an automatic gas shut off (in case flame goes out) and most modern burners have much less output for residential use, say around 10,000 BTU, whereas the Daisy Power burner has a range from around 500 to 15,000 BTU. I can not confirm exact numbers, but I do remember when my mom bought her cooktop in '81 she said something about the low simmer and high output in same burner was only available with the Chambers cooktop at the time.
Thank you very much–the parts look very similar. Now I just need to find them–the model KGCS100SWH2 exists for Kitchen Aid, Whirlpool and Maytag.
