Hi,
Hoping for info concerning a buzzing sound coming from air handler.
We live in a high-rise building(24 floors). We are on a building wide system with air handlers in each room.
Small bedroom unit has history about this time each year(last 5) that start buzzing. Past years maintenance would come up said replace "RELAY" and it's cured until next major season change.
Building last year underwent new management and maintenance men.
They monkeied with unit for several weeks. Changed thermostat 3 times, put a switch on bedroom wall cause after changing thermostat the unit won't shut off no matter what thermostat is set at.
Last Friday buzzing started again. As a rule it takes several complaints and couple weeks before new maintenance comes to check any complaint for repairs.
Past years could just flip breaker off and noise stopped. Now doing this does no good. It contuies to buzz.
Anyone have idea what is wrong cause this buzzing is getting very old.
Thanks in advance for any info.
Later,
Mike
