    Experiencing an unusual situation with a York heat pump

    Hi everyone,

    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!

    Call the company and ask the service manager if he will send someone out on a "callback" basis. That means the service call would be no charge, a warranty on the previous diagnosis and repair.

    Thanks for responding, Timebuilder. I will try getting a callback. I suppose it's only right. Do you think this blower situation is cause for worry? I'm going to be out of town later in the week (though my girlfriend will be staying here watching the place) so I will need to hope they can send someone on Monday.

    Worry? No. BUT, I would want to find out why the first service visit did not address the concern.

    There are several reasons the indoor motor could shut down when set for continuous run. There is a cause, and it should be identified.

    Absolutely. I guess what I'm asking is, if I can't get a tech over on Monday and the situation needs to remain unaddressed for a week or two, should I be worried about a serious system failure and losing all heat in the middle of winter, or is it likely that the system would continue to run as-is, with the odd momentary fan stoppage? Also, should I be concerned about it being a possible safety hazard?

    I would have to know what the cause and the correct solution would be in order to give you a sensible answer.


    Don't try something like this yourself. This would be beyond the majority of intelligent homeowners' abilities, so call the service company and ask that the service manager call you back. Unless, of course, your service company has only one tech, who is also the owner.

    I was afraid you would say that.

    That does make sense. Fingers crossed that they can send someone on Monday.
