James F San Diego , CA April 10, 2016 Appliance: Model JENNAIR COOKTOP CCG2520W "welded" venturi tube missing o rings broken gas line 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. =This is original work from James Forgione, K6JRF and may be used if it’s used in its entirety.= Read More... 20 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours Tools: Screwdrivers, Socket Set
Jill P Winchester , VA October 07, 2014 Appliance: Thermador Gas Range PRG366US The venturi tube and jet holders were welded together due to years of high heat I converted a natural gas Thermador range to LP. IN order to do this the jets had to be changed over to the LP size. Since the two parts were welded I had to cut the venturi tube nut off. To do so I used a step drill bit (up to 3/4" diameter) and cut through the top of the venturi tube from the inside out. Once the tube's top was cut through the venturi and jet holder assembly was easily removed by disconnecting the gas-line. With the assembly out a new jet was installed and the unit re-installed in a matter of a few moments. Thanks for the quick shipping the repairs were done and ready for installation in short order. The price for the parts was reasonable, the shipping fees were great and the quality top-notch.

Carmine P New York , NY March 18, 2018 Appliance: Model THERMADOR PRG304US Front left burner igniter works but no gas; Thermador PRG304US Had two different repair companies come in to repair my Thermador PRG304US Range. Both explained the the "broken" parts were no longer available making the repair impossible and thus I would have to buy a new range. Ok, but before I shell out $5K to replace the one I had, I needed to answer the questions I had. After twenty minutes of online research and the help of AppliancePros I was able to repair my own range. The techs obviously mis-diagnosed the problem, and not only that the one guy "pretended" that he attempted a repair that he never did. Repair was not overly difficult for someone with a little "handyman" skill and common sense, but was time consuming. Had to remove multiple parts for proper exposure to allow replacement of solenoid. The Venturi Tubes were frozen also adding to the difficulty and time required.

Donald A Hamilton Township , NJ November 26, 2019 Appliance: Model PSRE304 Front left xlo burner would not light on Thermador PRSE304SS The biggest problem is taking apart the cooktop venturi/burner assembly. They were fused after 20 years of use. These have to come out to get to the electric gas solenoid which I thought was not opening to let gas to the burner. I ruined the two Ventura’s and jet holder and the two gas lines getting them out and replaced them with new from appliance parts pros. Before I destroyed the old parts I figured out that it wasn’t the solenoid that was bad but I wanted to be able to see how everything looked underneath in case I needed to get to them in the future. First I made sure that the parts I was going to destroy were in stock and they were so I used penetrating oil a 20 mm flat bottom socket and then a unit to drill the hex head off when the wrenches couldn’t loosen the venturi and started spinning the jet holder around breaking the attached gas tubing. I used 1/4” copper line from an ice maker to make new lines and put everything back together with anti-seize. The problem was the potentiometer. How I found out have I just switched the one that was working with the one that wasn’t and that was it. Appliance parts pros had all the parts in stock and shipped out to me in a few days and then it took me about a half-hour to put everything back to new condition. Works perfect for $105.00 thanks.

Seaborn H Conroe , TX November 20, 2016 Appliance: Thermador Gas Range PRG366US Oven failed to light broiler also didn't light for a year before oven failed burner ignitor loose Replaced both ignitors. Since I was working on the range I also overhauled the final 2 of the 6 burners on the stove top. Venturi tube and jet nuts were frozen and could not remove drip tray for cleaning and access to ignitor clip. Had to drill out Venturi tubes using a tapered bore bit. Used Dremmel with cutting wheel to remove jet nut. This range has been heavily used since new for 16 years. Works like new, again.
