I purchased a home about 8 years ago that came equipped with a York heat pump / air conditioning system. I'm controlling the system with a Lennox Signature Stat and these days, I run the fan / blower on the "on" setting, so that it runs continuously.
In the past week, I've noticed several instances (hours apart) where the fan would shut off for a minute or two, then start up again. I called in my HVAC maintenance company and after taking some readings, the service man felt that my capacitor needed to be replaced. He replaced it, and less than 24 hours later. I noticed the fan stopping, then starting up again about a minute later, as before. I can't afford another service call. Should I be worried about it stopping completely and leaving me without heat, or something worse? Given that we're in the middle of winter and its below 0 out, the timing's not ideal.
Would anyone know why this might be happening?
Part of me wonders if this may have always been happening and I only noticed it for the first time the other day.
Also, the system power isn't cutting off - I know this because the fan stopped while the system was in auxiliary heat mode, and the aux heat lamp remained lit while the fan stopped working.
I'm kind of freaking out now. Any input would be hugely appreciated!
