Ge Electric Range JBP35W0H2WW

[ret]

Hi, I have this range and I'm having an oven issue.  I just replaced the oven element, the oven censor, and the main control box all brand new.  Now I try to heat my oven to 350 degrees, and I have an oven thermometer in it and it only shows 250 degrees when pre heated to 350.  If I let it go another 10 minutes then the temp comes up to 350, please if any suggestions I need them, I'm about to pull hair out over this one.  Thanks

Those oven thermometers are very slow to react. Also, sometimes the oven control is programmed to beep early. Set the oven at 350, wait 20 minutes, and then see what it says. I would rely more on the baking results than that thermometer.

Make sure you don’t have any aluminum liners or such in your oven. 
 

then bake a batch of cookies. See how they turn out.

I tried to bake blue berry muffins in it, and this is where we noticed that by the time it should of been done they needed to bake more.  Since I have replaced the parts I'm gonna try again to bake something and see how long it takes,  I have one of the vinyl liners in the bottom of the oven for spills, it's not aluminum.  Thanks for the replies

If it’s blocking the venting in the bottom panel that’s your problem. 
 

take liner out and bake some cookies.

to verify oven temperature, you need to run 7  heating cycles.......Insert a digital thermometer probe....Set oven temp for 350 degs...If there is a bake light use that for heat/oven "ON" and "OFF"  when the bake light goes ON write the temp down, when the bake light goes OFF write the temp down.. Do this for 7 cycles... add the 7 ON and then add the 7 OFF.... divide the total ON  by 7, it will give you the average low temp.....Divide the total OFF by 7, it will give you the Average high  temp... Then add the totaled ON  and the totaled OFF, then divide by two, that is the oven temp average...Some times this test will take 30 to 40 minutes but it is to get an idea of the oven temperature..
