Display on hob beeps and flashes randomly

when it does that check voltage from transformer to control board if voltage loss bad transformer if good voltage bad board

make sure not in a demo mode or on a program if ok bad control board

Probably the clock and/or control board could be failing at random. The erratic oven start-up could present a safety hazard.

First, make sure the oven is connected to a grounded outlet, and that the outlet is actually grounded. If that checks out, you probably have a failure of the control panel. If it's an expensive oven, it might be worth repairing; depending on its age. Over 5 years old, I'd replace it.

An SE error message on the display of a Samsung ceramic hob means the control panel sensor has been on for too long.
There are a few reasons why the sensor could be saying it's been on for too long:

• Touching the key area for more than 10 seconds.
• Leaving a wet cloth on the touch key area.
• Spilling a liquid on the key area.
• By touching 2 or more keys together. All of these can be fixed by turning the hob power off at the wall, then back on again.

Hi

This means a loose/broken wire on the oven temp sensor or the oven temp. sensor itself is bad and should be replaced. To solve this issue test the oven temp. sensor, it should read between 1080-1120 ohms, if the rating is more then that and the door appears to be closing fine then it is the control board that is bad and should be replaced. Hope this helps...please post back for further assistance.

Frigidaire's slide-in ovens feature an electronic oven controller, which serves to monitor and diagnose most electrical problems within the oven. If any of the oven's electrical systems fail, the controller will prevent the oven from functioning and will display a flashing "F" code on the oven's digital display and produce a beeping sound. To stop the beeping and clear the display, press the "STOP/CLEAR" button on the oven's control panel. Many times, the problem can be remedied by simply resetting the oven's controls. First, turn all of the oven's control knobs to the "Off" position, then allow the oven to cool to room temperature. If, after turning the oven on again, the "F" code still displays on the digital display, contact Frigidaire, as the wiring is likely to be defective.

f1 is a bad range control/ touchpad, here the part number for a white clock for model number MER5770aww 74008106 approx 150 bucks

Same issue w/our Thermador CM301. F23 and F24 codes - BSH acts like they have never heard of the problem! Awful service. This should be reported to the Consumer Board.

The touch pad may be defective. There is a membrane behind the buttons that will cause problems like that. The only cure is to replace the touch assy.
