Sienens microwave HFT879 fault

When power is applied, top display illuminates and the fades after approx. 10 secons. Bottom display then reads ER4 - I think this means Error number 4? No fans work and the oven appears dead apart from a the ER4 message. The manual says that ER4 is a temerature sensor fault, but I'm not sure where this would be located in the microwave. Any suggestions would be much appreciated.

Exactly the same problem over here, but after our house was hit by lightning, so not really surprised about the cause of the problem. If you look closely, you can still see the displays on a very low light level. I can still choose a microwave program, turn the time etc, and see the time changing, but start won't just just work.

I am looking fro a Manual to print off for A NEFF Microwave Oven model HFT879. Can anyone help please?


Jon, everything I can find on it needs an "E-number" off the plate on the bottom of the unit. You then should be able to go to
https://portal.bsh-partner.com/portal%28bD1kZSZjPTAwOQ==%29/PORTALFRAME.HTM

and find your manual. It will be in PDF format which requires the free Adobe Acrobat Reader. Just google it to find a download site for it. Best I can do right now. Good luck.

Cannot read display from below.


How old is the microwave oven, and what brand is it? Many Jenn-Air ovens and microwave ovens suffered from displays that would fade out after 5 or 6 years, and the only cure is to replace the control/display board. Also if you burned food inside the oven, it is possible that smoke particles have settled onto the display window (on the inside where you can't get at it, unless you take the panel apart).

Neff b6774N0gb/02. Inner glass shattered. replaced. Internal fuse blown. replaced. Now microwave working (heating water) for approx 5 sec, then switching off, beeping and showing E1 fault. Also display...


Usually if this model stops after approx 3 secs it is an invertor or mag fault. Check that the aerial cover is clean Page 3 of the breakdown part position 315. If this is really grubby it would be the cause of the door shattering. The PTC is not used on the microwave function so may be an additional fault. Check also the alignment of the door switches as this can also cause a similar fault. My best guess is if you remove the mag, you'll probably find scorching on it and it (and the invertor) will need replacing.

The inner door glass shattered and now no power


There's a safty switch which prevents the unit from operating if the door isn't fully closed. When the glass shattered a small piece may have blocked the switch from operating properly. Check around the door seals for any irregularities.

HME9750 error Er4


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.

Let us know if the hard reset does not fix it.

if appliance runs for approx twenty seconds this is nearly always a magnetron fault usually a cracked magnet or burnt out anode the electronics are detecting an unusual power fluctuation and shutting appliance down for safety you will need service tech to sort.

It would seem there is a bad connection in the fuse holder or in the wall socket or in the microwave itself. Maybe you can narrow it down to the microwave by trying other devices in the wall socket. If it's the microwave, it's time to call for serivce.
