Oven temperature low

My oven’s broiler works – high and low settings, and the top burners work.

However, the bake temperature is low. It starts to heat up – the oven starts at 100 degrees, it gets to 153 degrees and stops. It never heats up over that.

There is no malfunction code.

What’s wrong? Sensor? Igniter?

Thanks,

I hired a service man. He replaced the igniter and the problem is fixed.
