  • It sounds like vibration noise, suck/blow noise and squeaky fan? For the vibration you could try a rubber matt under the assmbly, if the entrire wall vibrates not sure you can do much with out a major rework. The suck/blow. Does the lovred door being open closed make any difference to that noise... may be indicitive of not enough makeup air. Squeaky, oil it? – beast May 23 '16 at 14:49
