F03 Displays I cant use my oven it just shows F03, I used to be able to turn it off then after awhile it would be ok. But now F03 is permanent. Can you tell me what it refers to and how i overcome it. Regards ken Mcloughlin

Possibly old FIXYA question has information to assist:

I replaced the temperature sensor and the F03 Error persists. Looking through the manual I find no ref to a thermal fuse, so I am assuming my my model does not have one. Also I installed a brand new Power Control Board and still have the F03 error. The issue started when I fitted the Control Unit, sets temperature and timer for lower oven.

I managed to resolve that problem. When you have BOTH F53 and F03 error codes, it's not a sensor fault (although F03 is the big cavity sensor and F53 is the top one)... it's a faulty capacitor trouble. On the main board there are 4 electrolytic capacitors, just replace all of them and you're ok again. It's quite simple and very cheap. :-)

An F3 on most ovens means a faulty sensor. If the control does not know the temp it may naturally lock the door.
If it is open shorted or out off range temp wise it is bad

Hi

Code F03 usually means that the oven temperature sensor is 'open circuit', that is not working at all.

The remedy is to have it replaced.

An F03 code is a open sensor, shorted sensor, or bad control board. This video shows how a sensor is checked

Hi


Thanks for using FixYa. F3 error means Open oven temperature sensor or thermal fuse. You’ll need to replace oven temperature sensor or thermal fuse to resolve the issue.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

On this model, F03 indicates a faulty power control board (also known as the "Capricorn" board by Whirlpool technicians). A new oven with no guarantee? There is usually a reason something has no guarantee, in your case, a faulty control board. It is a relatively expensive part unfortunately.
You can try disconnecting from power, removing top panel from oven. The large square electronic board you see on the top of oven is the power control board. Check all plug connections are OK, especially the large thin multi plug that goes to the display board- I have had a poor connection at this plug causes F03 faults. If still no go, power control board will need replacing

f03 error is a sensor error.you could have taken an ohm reading on the thermistor to see if it was bad.if you replaces the t-mistor then the only other component responsible is the board.make sure all the connections on the board are clean and tight before you replace it.
