20 Most Recent Neff H5470N0GB Microwave Oven Questions & Answers

I have never heard of a "magnetron fuse". Fuses are easy to locate on microwaves, though. The easiest way is to follow the power cord from where it enters the oven's frame to where it terminates on the board. There is a fuse in the immediate vicinity of the termination. You can check the fuse with an ohmmeter...it should read zero ohms, anything else means the fuse is blown.

If your oven is blowing fuses that means there is something else wrong with it, most likely the magnetron. You can't miss the magnetron, it is mounted on the side of the cooking cavity, you can identify it by its heat fins. If you want you can trace the wires from the magnetron back to the board, there usually is no fuse in that line but a capacitor is always in that line. Check the capacitor as well, if reads zero ohms it is bad and it is what needs to be replaced.

I am curious as to what is going on with your oven. Do the lights and fans come on but it doesn't heat or is it completely dead, no lights, no display, nothing?

Either way, I am including a link for you to a site that has all the parts and accessories you need for your model microwave. I hope this helps, here is the link: http://www.espares.co.uk/parts/microwaves/neff/h5470n0gb%2f02/p/1095/1126/0/553422

Any repair to a microwave should only be carried out by a competent engineer as even when the unit is unplugged there is potential for a large amount of voltage to be stored by the capacitor (which in the case of this model is part of the inverter board). I suggest that you bite the bullet on this one and organise a call from the manufacturer assigned repairer.

Possibly the magnetron is not producing power and as the cavity temperature is not rising, it cuts out.
Is there an error code in the display?

Hello,

What you are to do to solve the problem is to do a general troubleshooting on your oven below are instruction to follow.

The Microwave is a counter top model with a variety of preset cooking options, including timed cooking at a variety of power levels and sensor-cooking settings for popcorn, rice, beverages and single-serving reheating.

The sensor cooking and reheating features detect increasing humidity levels inside the microwave and automatically adjust cooking time for various types and amounts of food. This microwave also includes a turntable and an electronic control panel.



Instructions below are step by step solution for your oven

1. Check to see if the microwave will start. If it will not start and the display panel is blank, you may have a power problem. Unplug the microwave and then plug it back in, making sure that all three prongs of the power cord are fully inserted into the wall outlet. If this doesn't work, check your home's fuse box. Reset the circuit breaker to restore if necessary.
   
2. Ensure that the microwave door is fully closed. Press the Clear/Off button to cancel any previous cooking instructions. Re-enter your cooking program, including cooking time and food weight if necessary, and press Start.
   
3. If "Err" appears on the microwave display, press the Clear/Off button and reenter your cooking program. The "Err" message will appear during the sensor-controlled programs (Popcorn, Rice, Beverage or Reheat) if the door is opened before steam is detected or if no steam was detected within the maximum amount of time allowed by the microwave. Be sure to leave the door closed during these programs, at least until time is shown counting down on the display panel.
   
4. If your control panel will not work or if an "L" is displayed on the screen, press and hold the Clear/Off button for a full three seconds to unlock the control panel.
   
5. If your sensor reheat program is resulting in under- or overcooked food, first try decreasing the amount of food in the microwave; the sensor programs are designed for single servings of food. The sensor reheat function works by measuring humidity inside the microwave--do not use a tightly-covered dish with this setting because no moisture will be able to escape and the food will overcook. Be sure that cooking containers are dry; moist containers will increase the humidity in the microwave and mislead the sensor, resulting in undercooked food.
   
6. If your turntable is not rotating, first check to ensure that your food container is positioned so that it can freely rotate without hitting the microwave's interior walls; using a smaller food container can fix this problem. If the turntable still will not rotate, lift the turntable from its support and replace it carefully, ensuring that it rests evenly on its support.
   

Good luck.

Thank you and thanks for using fixya.

Finally worked out how to do this today! I don't know what model you've got (I don't know what one I've got - it's built in and we've lost the manual) but try pressing the START button for six seconds. This should change the default from 30 beeps to 3 beeps. Bliss.

Time to replace the door switches.

If microwave is clean (nothing spilled inside) your magnetron is probably getting weak/going out. Don't take it apart it's very dangerous unless you know what you are doing. Scrap it and buy a new one. They aren't too expensive, even on a budget.

Not easy. All microwave repairs should be done by a professional. Oven doors are easy, but they make microwaves harder because they need to be sealed and checked for radiation leaks. Traditional ovens are easy, microwaves aren't. https://www.google.com/search?q=replace+the+inner+door+glass+on+a+neff+C67M70+microwave ..
