First, your broiler is not connected to your oven thermocouple (Temperature sensor). When you turn on your broiler full load amps go into the broiler element with no adjustment.
There are only three components that control your oven operation:
1.) Heater Element - Inspect your heating element for cracks, sparking or corrosion on the two contacts on the back wall.
2.) Thermocouple - This is a temperature sensor inside your oven. It is about the diameter of a coat hanger wire. Either it comes straight out of the back upper wall or is mounted on the back wall.
It is disconnected and removed from the upper back of the oven.
You should get a meter reading of 1000-1100 Ohms if the component is good.
3.) Oven Control - The control communicates with the thermocouple and increases or decreases the amps to the oven heating element. If the thermocouple is good then the oven control needs to be replaced.
If in unsure, replace them both.
Recently, I replace a digital oven control for a friend. Sears wanted $256.00 for the control. I purchased a remanufactured oven control over the internet for $30.00.
Get the oven model number off your oven. It is on a metal tag on the face of the oven after you open the door.
Go into the following website. Put in your oven model number (on the left). You will get diagrams and parts part numbers. Record these numbers for the above components. Put the part number in your computer search engine and search best price.
CAUTION: If you replace a electrical control board GROUND YOURSELF by touching something that is bare metal. Static electricity will knock out a control board.
