I bought a second hand oven that seller claimed worked but needed the wiring to be fixed in the function selector switch. there is an attached picture of what the wiring looked like when i opened the oven.
i've attached the image of the wiring diagram sticker on the back of the oven. there are a few icons I dont understand and it doesnt make sense to be that terminals g,e are both empty. where is the switch getting live from?
in order to reverse engineer the problem I disconnected all the spade connectors and measured across the numbered and lettered sides with a multimeter and recorded as I turned the knob which pairs were shorted for each function.
these are the results
- off: nothing
- light: 8,1
- both elements: 8,6,5,1
- bottom element: 8,6,1
- top element: 8,5,1
- low rotisserie: 8,7,2,1
- hi rotisserie: 8,7,2,1
- hi rotisserie & fan: 8,7,5,3,2,1
- both elements & fan: 8,6,5,3,1
- convection: 8,4,3,1
- clean: 8,3,1
I concluded that the bottom element need to be connected to 6, top to 5, the fan to 3, the convection elem. to 4, 8,1 seemed like live and neutral for the lights, and 7,2 were the rotisserie motor and grill elem.enter image description here
there is a picture of what the wire looks like after I tried to fix it. when wired based on the findings above and my understanding of the wiring diagram the clock turned on but would cycle through turning off with a click, turning on and displaying --:--. as if it was resetting every 3-5 seconds. none of the oven functions worked.
