My oven is beeping really loud and keeps flashing f7 where the temp would be. i turn it off with cancle but it turns back on.

Turn off house breaker to the unit at the breaker box of your home. This will be a double breaker.

F7 Touch pad or Control board...... Most techs start with touch pad.

HI. This is the result of a failed function key. This is an integrated part of the main control board. Unfortunately, this is not repairable, and the main control board will need to be replaced, asap.

Contained within the oven, usually behind the backgurad, there is a tech sheet. DISCONNECT POWER and pull off back panel behind backguard to locate sheet. Within this sheet there are a list of fault codes and the corrective procedure.

F7 A = Function pad button stuck or
B = Bad clock Unstick button or
Replace Electronic Range Control (ERC)

F7 A = Function pad button stuck or
B = Bad clock Unstick button or
Replace Electronic Range Control (ERC)
It looks like you have a function button pad stuck or a bad clock.

Unstick button or replace electronic range control.

A function pad is probably stuck.
Push all buttons several times each. Often this will clear a stuck pad.
If that does not work replace the clock.

F7 stuck keypad
Stuck keypad may mean relay is turned on.
Determine if problem is with the Key Panel or Control by:
1. Pushing CLEAR/OFF pad.
2. Disconnecting Ribbon Cable from control and waiting at least 32 seconds to see if Code recurs

If code recurs, problem is in the control. Replace control.

If code does not recur, problem is with the Key Panel.

short inthe key pad, thinks a button is being preesed for an extended period of time youll need to replace the keypad/ electronic control

It depends on the actual model number (that you didn't supply), but most Kenmore F7 errors indicate a bad keypad or bad control panel. If you unplug the ribbon cable from the keypad to the panel then plug the oven back in and it starts beeping again, it's a bad control panel, if it doesn't beep anymore, it's a bad keypad.

Please unplug the oven power with working on it.

F7 stands for a faulty touch pad, faulty clock or both. Usually it's the touch pad. Most manufacturers recommend replacing both of the components. First, because they make more money that way, and second, it's the easiest (although more expensive) way to fix this problem. If you'd rather try and save some $$$, you can perform the following test and hopefully identify which of the two components needs to be replaced. The test... Disconnect the power to the oven before performing any repairs. Something triggers the clock to display F7 error code. You can unplug the touch pad from the clock and see if F7 comes back on. If it does, the clock is bad. If it does not, the touch pad is bad. Hope this helps, APP tech http://www.AppliancePartsPros.com
