Re: Over the range microwave oven

The magnetron may not be cooling properly and the overheat is what is causing the shut down. The internal cooling fan will need to be checked for proper operation.

Kenmore microwave hood combination

If you have tried to reset the microwave oven by turning the mains power off and on without success then it is likely the display is faulty.
The only way to repair is replace the control panel board. This can cost a lot of money.

See this site to give you some idea. Best to contact a repair technician and get an idea of costs.

Microwave wont start display keeps showing door

most likely its the door sensor... this stops the microwave from turning on if the door is not properly closed (so YOU don't get cooked). Usually on over the range microwaves people tend to pull the door down as they open it. over time it can become bend out of proper position. Try firmly lifting the door up as you close it... if it runs now than you have your answer.

Microwave shuts off and reflects f-9.

F 9 means Fault Code 9. This means that the Microwave has developed a "Fault" and the "Brain" has determined what it "Thinks" the problem is and outputs that "Code" so a serviceman can consult the manual, to find the exact "Fault". In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

I have an LG over the range microwave oven and it is displaying "Touch start or power level and all the buttons are frozen, how can i fix this please help

The first thing you should do is follow the golden rule of electronics repair and unplug it, let it sit for a few minutes, and plug it back in. It'll probably reset and be fine. It may have just been a fluke, or it may start happening more and more and the unit's electronics will need to be serviced.

Ewave otr microwave

Some microwaves have a sensor built in so if the oven gets to hot the fan will come on to help cool it down. It should shut off when it senses it is cooled down to the proper temp. If it will not shut off the sensor may be defective. Its your choice to either call a service tech to repair it or just replace it. I would weigh the cost of the repair to a new unit.
