You don't refer to a particular brand / model, so it's not easy to get a manual for you. By the way, maybe the problem is easier to get the solution. Where do you hear the noise from? Is it from the transformer area? What is the noise like? Is it steady (at sound level) and bass (low frequency) or like spikes?

Waiting clarification, don't hesitate to post.

Thanks and regards

My Rusell Hobbs 20L microwave wont heat food,what could be the problem?

If the control circuit turns on the power supply to the magnetron tube, the big power transformer should hum. Then after a couple seconds, it should hum louder as the magnetron warms up and starts to put out RF. If everything stays stone cold, the magnetron is probably shot.

These are repairable, and the parts are available. But you have to decide whether it is worth repairing. If it's past warranty, probably not. I am a radar transmitter engineer with 40 years' experience with these kinds of tubes, and if my ten year old microwave quits, I'm going to just throw it out (after I take it apart just to see what quit).

Volume only hums. even with volume off.

The unit may need to be looked at by a Technician to determine the cause. Can be power supply, defective amp or head wires broken off the head.
Maybe more

Sub zero. 650 reefer. Significant hum coming from top mounted compressor, but still marginal cooling. Now a louder hum and unit no longer cooling.

Hi roger,

I see you concern, and if the unit does not cool anymore and there is a humming noise then you will need to replace or have your compressor repaired no doubt.

Have a nice day,

A big hum of 100 c/s in the output,i need the schematic for repair

You must be on 50Hz power. You don't really need a schematic to repair the unit. Since the hum is twice power line frequency, the likely cause is the electrolytic filter cap for the high voltage has failed. The cap should be obvious in the unit. It will be near rectifier diodes and have a voltage rating above 50 volts. To test, bridge the one in there with another cap observing the correct polarity. If hum changes, replace the original cap.

I have my dometic Rooftop ac unit. The heatstrip/fan run perfectly but when I turn on the ac...the fan runs good but when the compressor kicks on it just hums.

The compressor coming on does make a slight "humming" sound which is normal. Is the unit cooling properly? Do you think it is louder than before?

Harmon Kardon AVR220 Humming noise

The most frequent cause of a "humming noise" in electrical components is called a "ground loop". If you want an indebth discussion of just what this is, you may go to this link:

To reprogram a receiver channel with a different transmitter button once a code has been stored, there will be two options:
  1. Enter the transmitter program mode of the receiver channel to be reprogrammed. Using any unused button or combination of buttons, push out the stored code by pressing the unused button until a long chirp is heard, then repeat 3 additional times. After this, you can add any desired unused transmitter button. This action erases only that particular receiver channel, all other codes will remain stored.
  2. Enter the transmitter program mode. Using any transmitter button press and hold until a long chirp is heard. If a single chirp or multiple chirps, (up to 7 chirps), are heard, the unit is indicating that the transmitter has already been programmed elsewhere in the receiver. Release the transmitter button and within 5 seconds press and hold until a long chirp is heard. This action forces the unit to erase all stored codes of that transmitter.
The unit then exits the program mode the siren emits the program mode exit chirp pattern. All transmitter buttons for that transmitter must now be reprogrammed. Any other transmitter stored in the unit’s memory still remain operational. If the button is released and not pressed again within the 5 second period, no change in programming has been made to the receiver channel. The programmer can move onto a different channel or erase the transmitter codes as described in 1 above.

Load humming.(louder then normal.)

It does not heat.

I already replaced the HV diode. That did not fix the problem

It still has a loud hum and no heat. I'm guessing the magnetron.

The unit is six years old. I did not purchase it, the unit came with my house.

Humming oven clock

You'll need a new clock motor or clock unit. Once these units begin to hum, they must be replaced. Parts are available on the web, through supply stores or Sears Parts.
