Stove Heats to 350 but not to 450

[brokenstove22]

My 15 year old Frigidaire Gas Stove will heat to 350.  The preheat button works and it will beep once it hits 350.  The stove is hot and works fine.

However, when I set it to 450, the stove will stay on preheat forever.  It will not get hot.  It will not beep.  At this point, I will not be able to even get it to heat to 350.  If I wait a day, and try to heat to 350, then the stove will work.

The broiler works fine.  The burners work fine.

Should I just replace this?

Hi Brokenstove, Could you provide the model number for the Stove you have. With the lack of information provided there isn’t much we can do for you. Its possible its the temp sensor, thermostat, or control board. But with no model number we don’t know what components the unit has.
