Question about Neff H5470 Microwave Oven

1 Answer

H5470 built in microwave

The microwave had just finished cooking and about to be opened to take out the food when the display went blank. On inspection there is a 10A fuse on the main power supply board that has blown. The neutral terminal was very loose and slightly arced so I tightened this up and fitted a new fuse but it blew as soon as it was plugged in. any ideas?

Sound like the door monitor switched has blown or shifted out of position if the switches dont operate in tandem when door is opened or closed it will blow the 10 amp fuse and kill the display they will need to be checked by engineer if it is monitor switch they are not expensive to replace.

Not heating


Hello


Power Supply

Check whether there is a proper power supply. Look to see whether the cord is connected to a grounded 3-prong outlet and the cord is fully plugged in. If the electrical system is built-in and no power cord is visible, replace or reset the household fuse or circuit breaker.

Microwave Functions

Some basic microwave operational steps may affect whether the microwave is heating. Open and close the microwave door, as the unit will not function with the door open, and push "Stop/Clear" to cancel any previous settings, such as the timer, which do not heat the microwave oven.

Setting the Microwave

Once the power to the microwave has been reset, or verified as working, and the microwave is ready to run, select a new cook cycle and press "Start" to see if the microwave begins to run and cook food as expected. Allow the food to cook for the alloted time and then open the microwave door and check to see if the food has cooked or heated. Choose a longer cooking time and restart the microwave if food is heating but is cooking slowly.

Repair

If all efforts to troubleshoot the function and power to the microwave still do not get the appliance heating food as expected, there may be a repair issue that needs to be addressed. Contact professional technician for advice.

There is an unpleasant smell (like rotten food)from my microwave oven. I have used it for cooking for about 4 years. The inside (cooking space) is as clean as new. I have boiled water with lemon juice (and...


Unfortunately the fault can be that there is some organic matter that seems to cause the issue , it can be sometimes insect or small creatures that have caught into the magnetron high voltage and is cooked.Also it can be insulation failure on the magnetron that causes the smell on heating of the material. In all these cases the oven must be opened out- taken out and observed.
If the fault is in the magnetron, or the capacitor that is leaking or an insulation of the transformer, then it must be replaced. But in the first place check if you can remove the unit with your resources.

My microwave is completely dead. I have checked the fuse in the plug and it is fine. Any suggestions?


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.

GE XL1800 Micro fan won't shut off after light burned out


The problem appears, at least in part, to the door latch circuitry which cannot be serviced by the owner. If the unit is still in warranty, call GE customer care. If not, replacing the unit is your best bet. I just bought a new GE 1100 watt oven with great features for less than $100 If the door dosen't latch correctly, you could be exposed to dangerous microwave energy.

Microwave does not heat/cook


hi

power spikes are very damaging to a microwaves internal parts, it sounds like your transformer and/or magnetron are blown. if the unit is out of warranty I would recommend calling a repairman or getting a new microwave (the transformer & magnetron are expensive and dangerous to work on) also get a small single plug surge protector for the new one.

Whirlpool microwave/oven model RM286PXV3


Just so I understand, you replaced the fuse inside the oven? If so, I would suspect a bad thermostat attached to the magnetron. This device interrupts power when the unit gets too hot. I've included a representative photo. After so many years your magnetron may be bad, too. Once you get the oven working, if it cooks and doesn't trip the thermostat again, it may be okay. PLUS - It looks like this model has manual rotary controls. If so, it's common for those to develop bad contacts after so many years. I would consider that my third suspect. Those controls are called the thermostat (not to be confused with other part by that name that I discussed above) and the selector switch. One could easily be bad. You can check part prices at Sears online at http://www3.sears.com (the "3" is supposed to be there) Some other things that can cause a "dead" condition: - bad connections on the small circuit board where the fuse is mounted (if such a board is present) - bad connections in the wiring Good luck.
