Grill element was corroded and not working but bottom element was working. Oven light was working. Ordered and replaced top grill element in indesit FM 20 K.C IX GB multifunction oven. Now, there is power to the clock but no power to the oven now. Oven light does not come on either. Am positive the grill element is connected correctly. Have I overlooked something?

Quite normal...top element is for grill/broil only. Bottom element is for bake only. If the grill element were to come on during baking a cake it'd burn the top of your cake to a crisp.
Some grill/broil elements cook at 500-700 degrees.

Check the wiring on the elements for a short..sounds like a ground short

First things first. The oven element is totally separate to the grill element. The clock has to have a time set for either the top or bottom oven to work, whereas the grill will work without the clock being set.
The control knob for the top oven is the ONLY control that will turn the top oven lights on, the grill does not turn the lights on. ( If you want to watch your toast, you have to turn the top oven switch on to the first setting as well as operating the grill control).
To prevent the grill being operated with the door shut, there is a micro-switch on the door hinge that allows the grill to operate ONLY when the door is down. The grill control also does not illuminate unless the door is down. There are two options on the grill control - right or left. One way is the inner element only and the other is both inner and outer ones.
So if you have done all that and it still doesn't work, then the micro-switch could be faulty.
Best of luck

Hello,
Is The small amount of heat you are getting coming from the bottom element in the top oven or is half the top Grill element working.To start with you have a double grill element and either the whole element has gone or just half the element.This is controlled by a selector switch which could be at fault or the Thermostat that controls the temperature.

Hope this helps.

sounds like the circular element at the back of oven has blown.

A tripped breaker or blown fuse on an electric oven or cook-top, combined with an element that has stopped working, is usually a sign of a shorted, then blown (if the fuse or breaker no longer fail) element.

If you know how to use an ohmeter, you can pull the element, disconnect the wires from each end, then measure the resistance between each end of the element, and each element to the outer sheath.

A good element has just a few ohms of resistance between the wire connection points, and infinite resistance from the wire connection points to the outer sheath. Any readings other than that means the element is bad and need's to be replaced.

Brinkmann has a terrible customer service dept. You are better off with a new unit.

It may be the oven temperature sensor.
