Hi,
I've been combing this site for information, but I have a question I can't find an answer for.
Here's our situation -
- Last friday, we noticed the outside HVAC unit was making a loud humming/buzzing and the fan wasn't running.
- We turned it off & on from the inside of the house with no change. Buzzing stops when outside unit is off, indoor unit blows fine, the thin copper line was burning hot at the inside unit (didn't check the outside).
- Started looking here & saw the stick test. Fan moved freely with a stick, but we still didn't turn it back on for about an hour. In the meantime, my husband checked the fuses on the disconnect & called his HVAC buddy who seems to be on vacation.
- When we put the fuses back in the disconnect & turned it back on, everything started up fine & it ran good until sometime last night (today is Tuesday). We had a ton of ran dumped on us last Friday from a tropical storm & were hoping maybe something got flooded or something & we could make it until my husband's friend is available.
- So, today we left it off for about an hour, tried it & it still buzzed. Fan turns freely with a push. My husband went out to take off the access panel to pull the capacitor (all rusted up) to get a replacement & decided to pull the fuse & put it back on one more time just to see. Starts up like a charm.
He's going to get a new capacitor, new fuses & a new motor (just in case because with our luck it would run again until next friday night & go out for good in
100 degree heat) - but I can't understand why pulling those fuses & putting them back in does anything. Is it just coincidence that we finally let everything cool off enough?The outside unit is probably close to 15 years old & the inside unit is the original with the house (from 1988) so we're due for a whole new setup, but I'd like to make it through the summer & have the replacement done in the spring or fall when the outdoor temps are more bearable.
Thanks in advance for your help
