Almost all units do, required by law for protection. It may be the familiar looking one or a part that serves that function that does of course not look like a fuse.

MY CONTROL PANEL DOES NOT WORK AT ALL. THE NIGHT LIGHT IS ALSO NOT WORKING. THE SERIAL NO. IS 900170B THANK YOU, MYRTA JACOBO EMAIL: MYRTA JACOBO@HOTMAIL.COM CELLULAR NUMBER 786-285-4262


Sorry to read about your problem.
It seems your have a general failure in the power control or switch failure on the unit.

  1. No power to outlet (blown fuse or tripped breaker or GFCI).
  2. Blown main fuse - likely due to other problems.
  3. Open thermal protector or thermal fuse.
  4. Defective controller or its power supply.
  5. Clock needs to be set before other functions will operate (some models).
Microwaves must be serviced by technicians due to the inherent dangers involved in repairing these appliances. Internal capacitors can retain a lethal electrical charge even though the unit is completely unplugged. A microwave radiation leakage test must be performed on the unit following any internal component repair.

No power to unit


What has most likely happened is that somone slowly opened the door when the unit was operating without pusing the stop/pause button first. Doin this will cause the door interlock to blow the internal fuse as it is a design safety interlock to prevent the unit from operation with the door open.

Power plug unplugged

There is a 15A fuse inside the cabinet that must be replaced. Remove the cabinet screws 4 on the side and 6 on the back then slide the cover to the rear about 1/2 inch. Lift the rear of the cover up about 15 to 20 degrees and continue to pull the cover off.

Follow the power cord from where it enters the rear of the unit. The black power wire will terminate at the fuse block. Removed the fuse and replace it with an EXACT type replacement fuse. (buy 2)

If the fuse blows again there is another problem in the unit. If it works normally there is probably nothing to be concerned about. Just make sure that before opening the door you push stop before opening the door.

To re-install the cabinet cover graso the cover from the rear... holding the back of the cover up about 15 - 20 degrees and slide it back into place. Make sure to engage the side locking tabs with the front part of the chassis before installing the mounting screws.

Thanks for using FixYa.

I have a emerson microwave and all of a sudden it quit heating


Do you have any lights or display? If no it could be an internal fuse which you will have to unplug the unit and remove the cover. Look for a fuse, which should be in a socket, but I have also seen them soldered in line on the board. If lights and display work then you are looking at the Magnetron tube which could be defective.

My JennAir M170 just quit working, nothing.........bought in 1998. Time for a new one? If so, how do I go about just getting the micro for the combo unit? Or do I have to buy an whole new combo unit?


I would at least have a service tech look at it. Here are the comon items to check most of the time when a microwave just quits. 1 the internal fuse. 2 the power diode 3 the large capacitor 4. door open / closed micro-switches 5 the magnetron. The least likely suspect is the control panel yet can also cause the problem. You should still be able to keep this unit in service cost effectively. Until I had it checked out I would not give up on it.

sounds like the mag fan went out and blew the internal fuse they are ceramic fuses 15 or 20 amp available at hardware stores ,if this blows again it could be the mag overheated,but the thermal breaker should have shut it off before this,thenit can also be your h.v. diode or capacitor shorted

My microwave quit working


You have obviously damaged the circuitry. Service is expensive. Unless the unit is under warrantry my advice is to replace the oven. The newer ovens are very reasonable and have great features. Check Home Depot.

No light, internal fan...then no display


The light isn't a safety issue but I would think that the fan would be.

The fan is designed to remove excess heat from unit and keep it cool. Without the fan, you're now operating the unit under conditions that it wasn't designed for.

With the unit unplugged, try removing the cover and see if a fuse has blown. If so, replace it with the EXACT value of the original.

See if the unit powers up again. Try heating heating up something for 30 seconds to see if the Magnetron is still functioning.

If so, check to see if the bulb is good. Did the bulb and fan stop at the same time? If so, it might be something in common that controls both.

Don't operate it further until you have it looked at. You don't want to cause something else to fail.

Good luck!
