My 18+ year old Jennair cooktop, PN CCG2520W was in need of a rebuild b/c of a welded venturi tube on the right front [RF] burner. In order to remove the glass top cover, you MUST remove the venturi tube. To do this you have to DRILL-OUT the venturi tube which requires a new venturi and orifice holder. The repair was difficult b/c most of the parts are no longer available. But then I found a ray-of-hope.
I was able to find some Jennair (Maytag) parts but they are scarce. Later I found that some BOSCH parts are DIRECTLY compatible with this Jennair cooktop. It was this that allowed me to complete the cooktop rebuild.
First, the Bosch Ignition Plug [AP2838563 - 00189324] unit is IDENTICAL to the old Jennair 71001694 part. It’s the exact same size and accepts the same locking ring on the ceramic base. All of the ignitors were replaced since they were ORIGINAL!
Also the Bosch Venturi Tube [AP2825260 - 00189023] is identical to the Jennair 71001082 part. The venture tube was “welded” into the orifice holder assy so it couldn’t be removed. This part is EXTREMELY rare and without it, the cooktop must be scrapped!
Next, the BOSCH Jet Holder W/jet [AP2832927 - 00415498] is identical to the Jennair 71001086 part. Transferring the old orifice from the Jennair part to the Bosch Holder completes the fix and makes it identical to the original Jennair orifice holder assy.
The ¼” gas burner line [71001699] was broken and, unfortunately, there are no replacements available today. So this line had to be fabricated using ¼” aluminum pilot line tubing with compression ferrules to make a new gas fuel line that turned out to be better than the original!
On older cooktops, the Jennair “o-ring” [PN 71001077] seals that mount to the underside of the burners are long since deteriorated and substitutes are needed. Found some high temperature Vitron O-rings [75A Durometer, Round, Black, 72 mm ID, 76 mm OD w/ 2 mm Width] available from Amazon. These fit the LARGE burners [71001081] perfectly; simply cut them for the small burners.
So, bottom line, I have a rebuilt Jennair cooktop that works better then when it was new! Hope this helps somebody with their Jennair re-build effort.
