Hi Wally...The f9 error on this model points to a inverter problem..I would first check the resistance to the thermostat with a meter...If ok then check the wiring from inverter to control...Your problem most likely will end up being a bad inverter module or a control assembly..From what you are describing sounds like your inverter is the problem...If you do not have tech experience with working on microwaves i would take it to a qualified tech As microwaves store high voltage which can kill even when unplugged...
