making strange squeeking sound. I opened up the panel door and the circulating pump is right in front. It is bolted down solid to the floor of the frame. I think it might be the fan squeeking. It doesn't do it all the time but it seems to becoming more...could be I have finally noticed it and it seems like it's more. Any ideas if this is a big, major problem...is it going out...I don't know much about pumps, but this one has been on 24/7 since we got it....how long should circulating pumps last...anyone else have a squeek in the fan?
