My Olsen furnace is making a whistling noise when using the heating
unit only, there is no noise when using air-con. I believe it is the
fuel pump (A2VA-7116 Suntec) on a Beckett motor. Question: How do I
replace this pump myself or do I need to hire a furnace contractor.
As long as you can check/set pump pressure, obtain the correct single
stage or two stage pump, set under and over fire draft, replace oil
filter and nozzle, adjust electrode gap, use a smoke pump and adjust
CO2 and O2 settings with a digital combustion efficiency analyzer then
Id say you can just go ahead and have at it.
Is the air inlet screen very dirty? If there is a lot of dust occluding
the opening it may be making a whistling noise as the required air
passes through the remaining small open area.
Changing out the oil pump is straight forward but may not be the
problem. have two of these in my home and it takes about an houreach
to tear them down, clean and adjust them. Beckett has made these quite
easy to service.
