Bryant 395CAV blower speeds
Hello,
It appears that my furnace (Bryant 395CAV) isn't blowing cool air at a high enough speed. I don't feel that the house is as cool as it should be - the air coming from the vents is cold, although it doesn't seem to circulate around as much as it could. I've done some "balancing" and still.. I had the front off, the fan speed selection block has the following terminals filled: Heat, Cool, and Spare 2. Spare 1 is open. Perhaps this needs to be switched/rewired/etc? Can I do anything myself or should I call in a Bryant person? |

From motor red is low blue is med and black is high. Is black connected to cool connection? Other things effect poor air flow. Is the fan on the blower motor clean? Do you have a new and clean filter in return? Is the evaporator clean? Are all the registers and return open and free from blockage of furniture etc? Put a thermometer in a supply vent. Check temp at return.I the temp difference 18-20 degree? If you have pets inside house probably have hair on evaporator. Seen it many times. Good Luck
