The F1 code on a Maytag electric stove means the electronic range control, clock or touch pad is defective. You or a technician can do a test to determine which item is broken, but you must replace the electronic clock range in models where the touch pad and range control are one part.

Hi dpaulthomas,

The F3 fault code description is a shorted or open oven temperature sensor. The easiest way to resolve this error is to check the sensor harness and harness connection between oven sensor and oven control. If you noticed that the wiring is all ok, replace the oven temperature sensor (RTD).

Hope it helps.

Thank you for using FixYa.

Hello there:
Here is the code for these 2 codes hope they are very helpful for you
F3
Open or shorted oven temperature sensor Replace oven temperature sensor F5 Hardware and watchdog circuits disagree Replace clock assembly (also called the ERC)

when the clock goes off on my oven the oven stopsand will only come back on when it is cooled off.

There is only one sensor. Look inside the oven on the top right or left rear. The sensor is about 3 inches long,metal and about the size of a thin pencil. It will be held in by one or 2 screws. Unplug the range. Remove the sensor and disconnect the wires. Use a volt meter set for ohms. It should read 1100 ohms plus or minus 50 ohms. If it reads more or less replace it.
If you have no meter just replace the sensor. It is bad if the control says it is bad.

Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.

Replace clock (ERC).

you have a bad oven temp sensor probe

This is not repairable. you will need to replace the control board or (erc)-(clock)
