Jenn-Air JJW9530DDS problem
« on: March 20, 2012, 02:11:04 PM »
History, when we moved into the house in '07, the house was 4 yrs old. We had to have the door hinges replaced after move in, which was covered by the new homeowners warranty. That seemed to fix the super slow heating problem. These new ovens heat slow, for energy efficiency. Yesterday, my wife said she set the temp to bake 400 degrees. She told me the indicated temp on the clock said 400 degrees in a matter of minutes. The cheapo hanging thermometer inside the oven said 150 degrees. The Clock/PCB wasn't giving any codes. It thinks everything is Super!  Anyway, this morning I did a test of the temp sensor. It was off across the board by 200 ohms, so I replaced it. Of course, I didn't have much confidence it would fix it and I was right. But, it made my wife happy that I replaced something. I downloaded the service manual from this site and read it twice. What I don't see is a way to calibrate the PCB to the temp sensor. Can this be done or am I looking at a PCB? :'( :-\ >:(

The control board, 74009716, is the problem.  That's an expensive board.  You might be able to have it rebuilt to save some money.  I like to use http://www.corecentricsolutions.com. Www.fixyourboard.com is another option.

Thanks, that's what I thought was needed. I ran the numbers at the two websites you posted, no luck there. Just my luck. They serve up a pretty good savings. I will give them a call tomorrow, they may still repair my board.

Got my board back from Fixyourboard today, took 3 weeks for repair and return. They said they fixed it, replaced a bunch of bad electrical components in the temp sense circuit and, resoldered some of the connections . Now, the oven will preheat and the tone will sound that the oven is at the selected temp.  I have a digital ohm meter, it has a 3' temp probe and a cheepo oven temp thermmeter from the supermarket. I installed them in the oven near the oven thermocouple inside the oven. Set the oven temp to 350. The two temp sensing units I am using, both are telling me the temp is 300.  The oven display says 350. It took another 30 minutes for the oven to reach 350 per my temp probe and thermometer. All the meanwhile the oven display says 350. Also, when my probe and thermometer finally got to 350 the oven stopped cycling on and off (can hear the relays).  Same thing happens at the 375 temp. Didn't check any other temp.  Are these ovens that slow at heating? I'm afraid if I adjust the calibration the oven. It will then be too hot.  My wife has always complained about how long it takes to heat up. I'm not sure what to do at this point...any suggestions are welcome.

At this point I would replace temp sensor. There two different ones depends on a serial number of the unit. It sounds like board is working now, try a new sensor.

Since you changed the sensor I would try baking in it as testing thermometers aren't all that accurate. I use the tried and true method. Pillsbury biscuits in the tube (look at instructions on biscuits). 350 degrees at 8-10 minutes. Flat cookie sheet on the 2nd rack space from the bottom( that will center the biscuits in the oven cavity) I pre-heat oven for 10-15 minutes at least then test. If they come out you're fine. Biscuits work better that cookies and such because they have to rise and brown. Used this for 30 years and it works.

I agree with theoldstoveguy...if I have a customer that isn't convinced that the range is baking right and I feel after testing , that it is, I do the biscuit thing also.Works very well
