AMF Noises – automatic mains failure panel

AMF Noises – automatic mains failure panel (AMF) sounds can be heard are a warning before failure happens. Never ignore AMF Noises.

1.NOISE

If you can hear ‘chattering’ this is a sign that debris is bouncing around between the contactors in your AMF. They can be metal dust, loose screws, metal filings. Your AMF will still operate BUT….. it is an indication that parts are wearing and in need of replacement during the coming 12 months. The noise will get louder unless action is taken.

Solution-

Turn off mains supply and isolate. Ensure and check power is DEAD. Then take off the AMF cover and vacuum out any debris. Check for loose items. Tighten all contacts and screws. Look for any wear and fix.

Get your local generator engineer to isolate the AMF and clean out all metal debris . Clean and then safely re-energise the AMF

 

2.BUZZING

Loose Metal debris inside the AMF will cause a ‘Buzzing’ sound.

The Buzzing noise will become louder and needs to be addressed. This is warning prior to AMF failure.

Solution-

Turn off mains supply and isolate. Ensure and check power is DEAD. Then take off the AMF cover and vacuum out any debris. Check for loose items. Tighten all contacts and screws. Look for any wear and fix.

Get your local generator engineer to isolate the AMF and clean out all metal debris . Clean and then safely re-energise the AMF

 

3.SMELL

If you can smell ‘burning’ emanating from the AMF then this is a sign that the terminals or some of the terminals are burning out. REPLACE immediately as your AMF won’t operate once they have finally burned out

Solution-

Turn off mains supply and isolate. Ensure and check power is DEAD. Then take off the AMF cover Check for smells and signs of black where burning has taken place. Replace any parts of the AMF that show signs of soot ( blackening ).

Get your local generator engineer to isolate the AMF and replace blackened parts then safely re-energise the AMF

 

4.The Noise is getting louder

If you have done nothing for weeks or maybe months or even longer, does it matter?

And the noise is getting louder over the months ?

Does it really matter?

YES – should you not bother to do anything and leave the noise to get worst over time, the ultimate risk is FIRE !

Sort the issue as soon as possible or prepare for the worst.

You have been warned !!!!

 

5.NO Noise at ALL -Control panel dead

The control panel has no lights and is DEAD – Nothing happening

Solution-

First – check that the 13A supply to your generator hasn’t been turned off accidentally.

Second check to see if the batteries on the generator are flat without any power. Check the batteries haven’t been stolen or damaged or disconnected.

Third- Check that there is no water penetration that has entered the control panel from above.

For your safety always Turn off mains supply and isolate. Ensure and check power is DEAD. Then check as stated above.

If you still have no success, then get your local generator engineer to investigate as soon as possible.

If the control panel has NO life and NO images then as a matter of urgency replace with a NEW control panel. Control panels can fail due to age or component failure
