JTP15 Oven - Shuts down after preheating

Oven is 5 years old and gets used about twice a month! After the oven has reached temperature, the oven will shut down and power cycle.. the display goes blank and then comes back on and I have to reset the clock.

I have already replaced the control module behind the front panel, and I get the exact same result. Is it the oven sensor? Surely it's not that easy! Okay, I know.. don't call you Shirley... :-)

Any help out there? THANKSGIVING IS COMING FAST!!!

    Thanks for your fast reply..

    The exact model number is JTP15B0D1BB.

    I just tried the HI Broil, and it did the same thing after about 10-12 minutes. Power cycle. The display goes blank, then all digits light up, and the control module resets.

    Looking forward to your reply!

It sounds like the module is momentarily losing power when the bake relay clicks off. Does it do the same thing when you use broil?
Post back with the complete model number and I will try to find the wiring diagram for it and we will walk through checking it.

    I can tell you that the temp sensor should not cause this problem. It only changes resistance as it heats up, the board senses the change of resistance and converts it into the temperature and tells the relay to open or close. The only way I could see the sensor have any effect would be if it was shorting out at a certain temp, but the control should sense the short and give you a code. It normally would stay shorted also and you wouldn't be able to reset the oven. However, I have seen stranger things happen. The sensor is only about $15-20, so it would be worth a try.

    The obvious answer would be the control has a bad solder joint on the transformer. Since you have replaced the control that doesn't seem to be the problem, but it still could be.(more on that in a minute)

    I have the tech manual for the 14 and 16 series but not the 15 but they should be the same.

    According to the parts list for your oven, the transformer is mounted on the board, so we need to make sure all the wires are on the correct terminals. If you have changed the control you probably found the tech sheet in the top of the oven. Go over it and make sure all the wires are on the correct terminals as indicated by the lettering on the board, don't depend on where they were on the old board.

    Some of these ovens had a separate transformer with wires going to the board. I don't see this on your parts diagram, but if by some chance it does, you probably have a bad connection at that plug.

    If all this checks out ok, you would want to check the neutral wire to the control. The elements will work fine without a neutral connection but the control has to have it to work properly.

    If this is not the problem, that leads us back to the control. It is not unheard of to receive a new faulty control board, especially if it is a rebuilt board. The problem you have is one that would be overlooked by the rebuilders unless they were looking for it specifically. I have a GE oven about 2 yrs older than yours and put 3 controls on it before I got one that worked properly. They all gave the same failed sensor code but only every 10 hours. Oven worked fine other than that. I would shut power down and back on and 10 hous later the F2 code would pop up. Third board fixed it, four years now with no problem.

    Post back with what you find out or any questions.

I have a Superba built-in YKEBS 177 D56 ( dual convection/convention)...I think it might be about 10 years old.

Sorry I couldn't help with your problem, mine is similar to your though!!

Kenmore gas oven does not reach operating temperature

If your oven is 20 years old the temperature sensor system might no longer be accurate, if you have access to a temperature measuring device that can confirm that the oven is not reaching 350 then run it up and check that its not just your indicator light system. Some oven burners have air control and yours may have accumulated oven soil over the years. If your burner. Is behind a short wall like mine is, use a mirror and torch to check. A clean can bring things back to standard. Flame heat is from a good mix of. Gas and Air...
