Question about Microwave Ovens
Well it sounds to me as if there is NO connection, as the contacts are NOT lined up?
You need to find out what Pins the element is actually on, using a meter set to OHMS meter the element, and you should get a resistance, as long as it's NOT a short, that's OK for now,OK, now note the Pins. mark one Hot the other Cold. I use a red phase and black neutral, pen (or in USA use Black, Phase, White neutral)
Now CAREFULLY with the power On element on, check that OUTPUT and see what pins there is voltage on... and which connection is neutral.
So the Voltage, must go to ONE side of the element, the "Hot" side, the Other side, the "Cold" side simply connects to the neutral return.
As long as you are sure you have it correct, it doesn't matter how you connect those two points together, as long as it make good contact and is insulated and isolated from everything else.
usually when it says Oven sensor, it means the Thermistor temperature sensor inside the oven. These often go "Open Circuit" and stop the elements from working, because the "Controller" will not be "Allowed" to power them up. They are fairly simple to replace.
Also it may pay to obtain a service manual for your exact make and model, this will have schematics etc, to help.
Basically to work, you must have an unbroken path from the mains Phase IN, to the Hot side of an element, the Cold, simply goes to neutral, return. Any "Control" simply switches the Phase, ON/OFF.
The various Controllers simply in-disbursed between, IN & HOT side of the Element, with their contacts, in the Phase Circuit to the Hot side of the Element, across the element and then to Neutral, circuit complete..

Hello. Whenever you get a newly designed part for an older appliance you must refer to the original wiring diagram and the wiring diagram for the new part, and also test the wires to see which are hot and which are neutral. Until those things occur, other considerations are premature. Joe
