Hi,

I've got a Jenn-Air W30430p double oven. Both ovens don't seem to maintain temperature anymore. I attached a grill/grate thermometer and the temperature swings between 350 and 317 with the thermostat at 350. I replaced the thermostat in the upper and still get the temperature swing to the low side vs say 370-330. I have a replacement element on the way to also try in the upper.

Thanks.
