there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if contact is not through the microwave will not work.

Now keeping clear of the microwave, switch on, use a cup of water inside to test. If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.If there is heating without any issues, you can use the microwave safely

Hi,

You may even see the orange "glow plug" (called a hot surface igniter) glowing orange and so assume that it's OK. Not necessarily!! You have to measure the current/amp drawn by the igniter and compare it to this repair sheet before you can say it's OK or not. The gas valve has a bi-metal that open when a certain amount of current flows through it to heat it up. The igniter is wired in series with the gas valve. As the igniter gets older or weaker, it's resistance increases to the point where not enough current is flowing to the gas valve bimetal to open it up. As a result, the gas valve never opens up. BTW, a common symptom of the early stages of this problem is erratic temperature control in the oven due to delayed firing of the bake burner while cooking.

The hot surface igniter will not come on - check igniter with a ohm meter, you should have continuity through the glow bar, the glow bar can also crack = new igniter time. The glow bar comes on but the main burner will not light - you should have an amp probe to check properly, but often this is a hot surface igniter problem. The hot surface igniter often looses it's ability to get hot enough to open the gas safety valve. The safety valve can fail, but most times it is just a bad hot surface igniter. The hot surface igniter can also quit part way through cooking , in other words the oven may cycle a couple of times and then it just sits there with the red glow from the igniter. See this service sheet for the proper way and amp readings for the hot surface igniter system. Hot surface igniters do weaken and will eventually generate less heat than they normally could. When this happens they can still allow marginally correct current to flow to the oven gas valve for it to open but not get quite hot enough to ignite the gas burner immediately. When this happens, gas released into the oven can sometimes build up to the point where when finally ignited, the amount of gas lit can cause a small explosion inside the oven or cause an odor of gas with out the oven working. Yes, your glow bar igniter can glow orange-red and still be bad!! How a common gas valve works - click here.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Have you checked inside the microwave? Usually they have the manual hidden in there.

Replace the faulty door switch.

one of micro switch could be bad or the main board issue is there

Hi, My research came up with a shorted keypad (shorted key). The part number I came up with was W10258190 this is for stainless. I hope this information helped. Good Luck I’m happy to help further over the phone at https://www.6ya.com/expert/gere_bf68e6055dd61249

The SE error code means you have a shorting membrane keypad.

you would need to replace either the membrane keypad or the control panel frame assembly, which comes with a new keypad already installed.

unfortunately, those parts for this model seem to be unavailable. So the only option would be if you can find a used or "New Old stock" part on eBay or at a local or online appliance parts store.

If you can find either of these parts, that will fix your microwave:

DE94-01386S ASY CONTROL-PANEL (STL)

DE34-00233N SWITCH MEMBRANE (BLK)

The support page for your microwave is here, where you can find manuals and a helpful exploded view part diagram.

Good luck.

Replace the MW
