Heating, Air Conditioning, Fridge, HVAC/AC not blowing


The outside unit(radiator?) is running. In the attic the blower/heater is humming but not blowing. Fuses outside all ok.

You need to see if there is power going to the fan motor  and work from there.  If there is power, then the motor or run cap is no good.  If you do not have power, then you will have to determine what is causing the problem.  You did not include a model number, so I do not have any clue as to what kind of unit you have or control sequence.

I have been in the HVAC field for the past 18 years. I can help with most HVAC questions. I work on commerical buildings for the most part, and have yet to find anything I could not troubleshoot and repair, when repairable. I work on small 1 ton units to a 2500 ton chiller. Troubleshoot air flow, elect, and control problems. I attend regular classes to keep up with the latest and greatest.


I work on commerical sites, hospitals, gov't buildings. I can troubleshoot just about anything in the HVAC business.

5 years trade school, VFD training classes, Liebert factory training, some York and Trane factory training.
