Goodman air handlers model #GMP075-3?
I have a Goodman model #GMP075-3 RevB and when I turn it on it makes a horrible loud whinning noise. My husband thinks it might be a bearing in the blower motor. It stills blows cold or hot depending on how it is set so it works but the noise is so loud and annoying we don't use it. The noise starts as soon as the unit is turned on.
