Please post a new help request with your full model number plus more detailed symptom information, including:

Do the inside light, turntable, and internal cooling fan ALL come on when you initiate cooking?

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

These answers will help me judge whether it's in the high voltage section (magnetron, transformer, or diode) or the control section (door switch or control board relay or connection).

How to bake pizza in rival micro wave .??how to set it?

Unless the pizza was specifically packaged for microwave use, pizza cooking in a microwave is usually a bad idea. They don't turn out well. Although microwaves are referred to as "ovens", they really don't bake things, they boil them by heating the moisture in the product. Thus, pizza crust will not rise and get crispy unless the pizza was pre-made to be microwave reheated. Those pizzas will give instructions on how to microwave them.

It is a rival 4.5l. the heating element does not work anymore. need to replace it.

If I read the title it say PROBLEM WITH THE MICROWAVE, on the other hand when I Google the Rival 4.5L it is a deep fryer?!?!?, now if you'r talking about a Microwave oven there is NO heating element, what produces the heat is called a MAGNETRON... it can be replaced but it's cheaper to buy a new oven. Now if you'r talking about a deep fryer, you are correct there is an element inside the unit but as for it's replacement you need to check if it is servicable, some models are riveted meaning you can not disasemble it without braking the rivets... if you finally get it appart check the element for a part number if it has one than it's just a matter of calling a near by applayance store and order it (it would be even better to show the element to the clirk) than again the element could cost as mutch as a new fryer...

Rival Mod. #RGM41101 It sounds like it is working but it won't heat.

This indicates magnetron problem "heats food" this is the heart of the microwave oven and is cheaper to replace than to repair.

Rival Microwave Model RGM41101 will not heat

If the lead and the plug are ok and the panel lights up, do not attempt any further repairs of inspection. A microwave is an extremely dangerous appliance and should only be serviced by qualified persons.
