My 721.8059x microwave stopped working. It is displaying error code 7770 and leaves the fan running. Cycling power doesn't help.721.8059x

None of the keys respond or beep when pressed. After cycling power the "Enter Time of Day" message scrolls by a few times then there's just a semicolon on the screen. The 7770 error code appears slowly, one number at a time.

SOURCE: No key's work. Display and inside light is working

The Keypad is either faulty, or disconnected. Open the case, and remove the screws, holding the outer shell on. Inside, there should be a small board that covers the Keypad. Check to see if there is a ribbon cable, or some other type of connection going from the board to another part of the microwave. If all of the wires are connected, then you will probably need to replace the keypad.

IF there is an E attached to the 45, it is your control board and the control board would need to be replaced. This is per the "Washer Tech Data Sheet"Hope that helps...

It sounds like you just need some calibration. To calibrate incline, turn power on press press any incline buttons, as the incline try to change unplug the key. Now re-nsert key and incline will self calibrate,

What does error code E-13 mean


Hello there

Sounds like a 'gas sensor' (whatever that is) error. I recommend calling Samsung Support or a qualified Microwave Technician

Roper mhe14xm stopped heating. blew a breaker, the microwave comes on, but does not heat. It has a


If this was preceded by failure of the cooktop lights, then you probably need circuit board repair.

Check and see if the cooktop lights and vent fan both work. If not, that's a clue.

Always unplug an oven before removing or inserting bulbls, or there can be a filament short which sends a surge through the controller.

But the first thing I would suggest is a hard reset.

Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.


If that doesn't work, leave it unplugged for about 5 minutes.

If it still fails and comes up with a "d" error, then you might check the door switches. Help file here.

Once all that is checked, and ruled out, repair or replacement of the circuit board is probably indicated.

Khhc2090s trouble


The sensor errors are probably just from opening the door and interrupting the sensor cook cycle.

By the way, you should always press "Stop" before opening the door of a running microwave. Otherwise, the door switches will prematurely fail.

I would first check the door switches and their mounts. See this help file.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

Jenn Air Microwave Error Code


Hello Hec1152,
I have found the manufacturer contact information for you, but could not find information about the error code. If everything works fine, but the microwave is not heating your food, then the problem is most likely the magnatron or one of it's components, which sadly to say is the most expensive part to replace. Please feel free to contact the manufacturer via phone or live chat to get more details as to what the error code means.

If you would not mind, could you please rate my help. I would greatly appreciate it.

Model 72180883400


Hi,
F-9 error code indicates a defective control board, inverter or line voltage too high. f the microwave runs for about 7 seconds with a ticking sound..then stops and shows "F-9", it is the magnetron that has failed. The fact that the unit starts and runs with the TICKING SOUND means the control board is sending signal to inverter board and the inverter board is sending signal to magnetron. Magnetron is covered by full 5 year warranty, inverter board is only 3 years.
