Checking Oven Sensor
« on: October 30, 2010, 11:55:40 PM »
I've been having some issues with my oven temperature.  Typically it'll run around 100 degree's colder then normal.  Cooking is becoming a real chore(even more then usual!).  I checked my elements(electric oven) and they seem fine, both around 25 ohms resistance.  I'm not sure how to check the sensor though without damaging it.  It uses this part:

I tried putting fine wire into each slot and checking resistance that way but the numbers are just all over the place and maybe the sensor is hosed, but I'm not sure if the wire I used isnt causing a problem.  Is there some better way to go about this?  Or some way I can remove the wires from the plug they are in safely without damaging the plug?  

Thanks!

Ok I figured a way to measure.  Theres a top and bottom slot and it looked like the wires were in the bottom and I got no reading there and i tried the top and get a reading sticking the multimeter probes directly in.  Of course more answers means more questions.  These are the readings I've gotten.

Ice Water ~45 - 1012
Room temp in Oven ~73 - 1077
Room temp in basement ~70 - 1065
Armpit(I know ewww right) ~96 - 1113



So it seems to be working, although its lower then the temp that I read should be expected- 1100 at room temp.   However if this was the issue it seems to me like it should actually be running hotter since the oven would be at around 90 when it thinks its at 72 and the oven adjustment could take care of this. Any thoughts?  Most likely the problem would be the oven control?

Well after much consternation of closing it up and getting F3 codes Sensor Bad and trying to figure out how I made the problem worse and wondering if I screwed up the harness I finally found a suggestion about checking the resistance right at the control panel to verify theres no problem with the wiring.  So I did that and everything still checked out ok.  I also found some info in my manual that said 1080 was the correct room temperature resistance of the oven sensor.   So I'm nearly certain it is the control panel now.   One thing I was still wondering though, does it matter what plugs you use on the sensor?  I.E. The ground is listed as P3-6 and the other connector is P3-5 does it make a difference if they're reversed on the sensor.  Don't think they are, but I figured I'd check anyway.

No difference on which wire goes to ground.

Great, thanks for the info.  Wish I had that vid beforehand, could've done this in like half the time :)    Looks like its time to order up a control panel.

Just thought I'd update here.  I replaced the EOC and the oven is working like a champ again!  Thanks again for the help!
