Question about Carrier 38CKC036 Air Conditioner
Hi: I have a 4 year old carrier weather-maker infinity model 58mvp 060-14 furnace and in the past 2 weeks the ecm motor is sounding noisy and is veberating slightly when it is running. This is a new noise this heating season and since I have about 6 months of the five year total coverage warranty left on it, I'm wondering if this is a common problem and should I call for service? I know It is not the main blower motor itself that is making the noise because I have taken the front cover off the furnace and can feel the ecm motor viberating and the noise I hear is not there when the ecm is not running.
Thanks in advance for your advice.
Ecms are pretty reliable and electronic failure is much more common than bearing or bushing wearout. i suspect the fins on the blower may be coming loose from their pressed on spline and that will start a vibration or shimmy or you could have thrown a weight that balanced the wheel . best to use to warranty to get a new wheel. good luck
