Timer clicks constantly on & off and oven goes off

Without a model number its hard to be exact. If your oven is older it will have a clock timer motor that turns the dials or flips the clock display cards. This timer has gears and bushings that will be annoying as they wear and start a vibrating hum or clicking-usually not worth tinkering with..it can be taken out and checked or replaced. Electronic timers of course don't have any moving parts to the timer, but have relays in the circuit to turn the oven on and off. They do not 'whir'. This is the likely issue.
Repost..let us know.

Hey guys, I am having the same issues. My oven isn't turned on (not hot) nd it feels more like the timer/ clocvk are ticking?

Please help! The oven works perfectly just annoying having the noise constantly

what's the error number

Hello & Welcome to FixYa

F7 error code is displayed when the clock assembly/electronic range control (ERC) goes bad and needs replacement. Please get back to me if you have any other questions.

Hello everytime the power goes off & then comes back on my oven won't work until I turn the knob for the timer around as far as it will go then back again. My oven is rather an old type but maybe if you reset the timer or turn it that may help. Or check the meter box as well. dee

You could but if you disable the timer and anything goes wrong with it could invalid your house insurance if anything went very wrong.

I would suggest that a new timer is needed.

I believe this is because it takes a while for your oven to cool down (the cleaning cycle uses a very high temperature to burn up the grease and food). The timer is how long it takes before it will be cool, at which time the oven will unlock.
