Cannot unlock range. finger touch/pressure has no effect.

Have you tried disconnecting the whole cooktop from the main supply for about 5 minutes? Sometimes when reconnected the fault goes away.

Good Afternoon friend, that's a great question!

From my understanding your Electrolux range is displaying a code of "d-o". The code could stand for open door, could be missing a sequence, or a miscommunication within the control panel. I would recommend performing a reset on your range and you can do that by flipping the household circuit breaker off for roughly ten minutes. If that does not help resolve your issue I would suggest having a professional technician out to perform a proper diagnosis and repair. Hope this information is helpful. -Matt

PF indicates a Power Failure. Turn off the power supply (for 30 seconds or more) to the unit and then back on, select/touch the range cancel/clear pad and reset the clock. The range should work again, unless there was damage to the control during the power interruption.

Hello not sure volume can be changed but if it can look on the back of the unit or inside the back top plate there will be a tech sheet if it can be done it should be on it

Hello Larry D Harris - Does any part of the range work? I would recommend verifying that a fuse is not blown or a circuit breaker tripped. Test the power outlet with a lamp, hair dryer, etc. Another questions, does "Loc" appear in the display if any button is pushed? The Oven Lockout feature automatically locks the oven door, prevents the warmer drawer and most oven controls from being turned ON. If so, press and hold CLEAR/OFF for 3 seconds. A beep will sound. LOC will clear. The "DOOR LOCKED" will continue to flash until the oven door has completely unlocked. Do the maintop burners work? Granting that it does, you can try confirming that the shut-off valve on the gas pressure regulator is in the "ON" position (usually located on the back left-hand side of the range). This valve shuts off gas to the oven. If after the basic troubleshooting, you continue to experience the issue I would suggest contacting a certified technician to assist in the full diagnosis and repair of your range.

Hi,
Here below we have aprocedure to try to see if you can save the ERC.
F1 touch pad / ERC test
This simple test will help determine
whether the ERC (Electronic Range Control or Clock) or the touch pad is
defective when F1 error code is present.

Note: Some models
incorporate the touch pad in to the ERC as a single assembly, in which case this
test is not necessary. Simply replace the ERC (Clock).

Warning: If
you feel in any way uncomfortable performing this test or making this repair,
please contact a qualified appliance repair technician.

1. Disconnect
power to the range (unplug the range power cord or turn the power off to the
range at the circuit breaker). It is very important that the power to the range
has been disconnected, so please double check before continuing.
2. Gain
access inside the control panel.
3. Disconnect the touch pad (also called
keypad or membrane switch) ribbon from the ERC.
4. Make sure there are no
lose wires, or anything else that may cause a short when power is turned back
on. Assemble the control panel back the way it was.
5. Turn the power back
on.
6. Wait for at least one hour to see if the F1 code comes back (usually
accompanied by a beeping sound).
7. If F1 comes back, replace the ERC. If it
does not, replace the touch pad.

From the manual, page 7:

To Unlock Cooktop: Touch and hold the CONTROL LOCK/
ALL OFF keypad for 5 seconds.

Our hob has the same problem. I would really like to know the reason for this! Try using a rubber eraser instead of your finger - this works every time with our hob. Covering Up and Down arrows with the rubber, zeros it instantly just like using both fingers. Hope this helps.
