We replaced the upper sensor for the top oven. still show F3-1 , what should we do next?

Well, your temp sensors can still be bad. If not, there's always a new control board you buy!

However, I wouldn't drink water from that oasis without making ABSOLUTELY sure I'm not seeing a mirage.

The only common denominators between your upper and lower oven temp readings is the firmware and the oven thermometer you are using to visually check the temps.
What type of thermometer are you using to check your oven temperatures with?
If it's not a digital thermometer used specifically for testing ovens, you might just be leading leading yourself astray.
You need a calibrated thermometer. If I don't have a calibrated digital thermometer on me, I use two or three oven thermometers (the dial type) and average the readings.
It's the only way to be as close as possible with a digital probe.

If you have thoroughly verified that your oven is in fact not reading the correct temperature, then you can adjust it +/- 35 degrees F via your oven's control panel.
To adjust the oven temperature:
1 - Press Setup pad.
2 - Select the down arrow to scroll to the next screen.
3 - Select Temp Adjust using the Quickset pads.
4 - Select upper or lower oven (select models).
-"Set temperature offset using the Upper Set Knob" is displayed.
5 - Enter the desired temperature change using the Set knob.
The temperature can be increased or decreased up to 35 degrees.
The temp. change is displayed at the top of the window.
6 - Press the Set knob to accept the change.

Now, if you are still worried about the temp. reading being off, replace both the upper and lower temp sensors. That's all you can do besides replace the main board.

HI thanks for your question.. code F3 says to replace the oven sensor, located in the oven. top left corner. Replace the oven sensor. Thanks

The control on the upper bake element has failed.and needs to be replaced

F3-E1 Shorted wire or Temperature Sensor - locate short and correct it or replace Sensor.

go to RepairClinic.com and enter your exact model # for a listing of replacement parts.

Sounds like you have it figured, need to spend some moola..........

You can ohm out the sensor to the oven should be about 1100 ohms at room temperature.((the sensor is the little rod with two wires attached to it sticking in the oven, as temps change resistance changes which is read by the board) The upper and lower oven sensors are probably the same,you could just swap them to test, but probably not necessary,might also be confusing if you do not do a lot of testing on a regular basis. Remember to unplug unit for safety.

The bake element if it was not bad should be about 20 ohms, bad would read open........

Do you have 220 volts to the element. If you do then you have a bad element. If you don't then it is usually your erc (electronic range control) or your oven sensor. You need to test your oven sensor for the proper ohms, (should be on your wiring schematic), replace the sensor if you don't have the right ohms rating. You can also compare the upper oven sensor rating with the lower oven sensor rating. If your sensor is good then you need to check if your erc is sending 220 volts down to the lower oven element. Again you need to look at your wiring schematic(usually found in a sleeve behind the oven control panel), to determine which terminals to test. As always you need to be sure that you know what you are doing when you are working with live voltage. If you don't know how to work on live electical products you need to call a technician. It can be very dangerous. Good Luck, Appliance Specialists

HI. the oven control will interrupt normal actions if it senses an abnormal oven temperature. this can be caused by a faulty RTD(temp sensor), and, also, a faulty relay board if present.

Replace relay board, if present, or oven temperature sensor (RTD). Check sensor harness to make sure it is in good condition.

It is quite possible the control electronics have failed. There are separate relays for the upper and lower ovens. Ours recently failed the upper oven with the same symptoms and it was the electronic control. The other part is the overheat thermal sensor for the oven may be out.

No. just the one sensor part number 12001656. After paying a maytag repairman twice, I will now for the third time replace it myself, google the part number and you will see the different companies that sell it. Price runs up to 40.00, next time buy a different product and hope that Maytag goes out of business!!!! I know I will!!!
