Both oven and broiler on hotpoint oven model rgb745wea3ww wont heat up

SOURCE: BROILER WONT COME ON

If your BAKE function works, but the BROIL does not come on, more than likely you have a bad igniter on your broiler. The igniter is a glow bar type that comes in two basic shapes. One is round, and one is square. The round type igniter should draw between 2.7 to 3.2 amps of current to be considered good, while the square type igniter will draw 3.2 to 3.7 amps. The reason it is important to mention this is because, it is not uncommon for an igniter to still glow. and be bad. The igniter is designed to draw the required amount of current in order for the gas valve to open. Once the valve opens, you have ignition. This is a designed safety feature that prevents free-flowing gas from accumulating without ignition. An easy way to check is to remove the broil cover and turn the broiler on to see if you have any activity out of the igniter. If the igniter does not glow at all, a resistance reading can easily determine if the igniter is bad. It should read avery low resistance if good. If the igniter glows, but the gas valve never opens, take a current reading. If you can provide me with your EXACT model number (located somewhere around the oven door/lower drawer opening, or on the back of the range) I can track down a part number for. I hope this information is helpful to you.

change the oven ignitor.

Replace the ignitor.  You will need remove the bottom plate (remove the two screws back corners).  And the disconnect the wiring from behind.  This little part will cost you approx. $100.

Based on your description, the igniter is dead.
The broiler and the oven heat each have their own igniter. Look for the characteristic glow when the oven is turned on. If it is not visible, then you will need to replace the "OVEN" igniter...
Google the stove model for repair parts and locate the igniter. Not too hard to replace... directions are packed with the new igniter...
