Timer runs super fast, I dont think its heating at all. set for one hour, takes only a few seconds to run. Owned since 2003

A malfunctioning control panel or membrane can cause erratic behavior in your microwave oven. If the control panel is not registering the start command correctly, it may interrupt the cooking cycle. Try cleaning your membrane and control panel with a soft and damp cloth to remove the dust.
If cleaning doesn't resolve this issue, try resetting the microwave oven by unplugging it from the power source for a few minutes, and then plugging it back in.
The microwave may not generate the required heat to cook the food properly if the magnetron or high voltage capacitor is defective. This could lead to the timer counting down without any heating action.

Sounds like the microwave thinks it is running at 50Hz. They sense this automatically. most of the time a reboot will fix it. worst case, replace the control board.

1. Hold the Timer/Clock button down for a few seconds till it beeps and shows 12/24 hours.2. Type the time into the display. Use the minute buttons to set the hour, and the second buttons to set the minutes. 3. Press the clock button again.

this a problem with the clock , but the microcontroller can be defective by the power outage, see the diagram . how the microncontroller has the control for any equipment.
IN SHTE M.CONTROL BOARD CAN BE DEFECTIVE. go to the repair shop Tv FOR FIX IT. God bless you

No... you are not in a microwave induced time warp...
Your microwave oven needs a "reboot". The same thing happened to me.
Unplug your microwave oven, wait about a minute (more or less), plug it back in. Try setting/running your kitchen timer, boil water, etc. Your timer software on the microwave should be reset.
