Maytag Range Model # WGR5745ADW

[Waneewek]

My Maytag gas range has an F3 code that won't go away.  When I turn the oven to bake the burner would light and start to heat and then go into an F3 fault and shut down.  The tech sheet says that an F3 code is a temperature sensor issue, but I have about 1200 ohms when checked the sensor at the ERC.  I had a spare  sensor and changed it anyway and it still went into F3 fault.  I replaced the ERC thinking that would surely fix the problem and now the oven doesn't light at all and it goes directly to an F3 fault.  Any ideas?  Model# is MGR5745ADW

Thanks for your help.

Could you verify that model number? I'm not finding anything with it.

OK, that worked.

When you replaced the sensor, did you use a new, OEM sensor?

It's not uncommon for a sensor to test good at room temp but act flakey at other temps; for an illustration of this, read this repair story.

Yes, I bought it from Repair Clinic for another job, but it was the same part # as the one needed for this oven.

So, new sensor, new ERC and still F3? Must be a bad connection somewhere. When you replace the sensor, does this sensor connect to a pair of wires right behind the oven with wire nuts and then continue on to the ERC? If so, you may have a bad wire in the wire harness. You'll need to ohm each one from the harness connector at the ERC to the other end of the wire harness, at the sensor.
