I have a Honeywell ST9120C2010 Fan Control Brd at Indoor Blower motor - No Blower at any Mode - What should Voltages be to Motor when called for ( Blue. Red and White) wires.

SOURCE: bottom blower dose not go on

you should have two wires that go to a capacitor for turning the motor the right way durring start up then you should have two wires for run current. Now my motor has red and blue as the run voltage and blue and a white wire to the capacitor -6uf+/-10-5%@250AC. This cap is mounted on your fan shroud and refer to you top motor wire configuration, as both blower motors is in like the same wire colors to cap. Now my lower motor keeps blowing the thermal fuse and dose not overheat as the thermal needs at least 360 degrees of heat to blow yet my moter when running is not that hot.... I would replace the motor and cant seem to find one where did you find yours.

SOURCE: mars motor has no white (common) wire??

You are looking for the nuetral wire,look on the mars motor it should have a wiring diagram stamped on it to answer your question

Hello GREG Black=hi speed blue=medium speed red=low speed white/brn=common or white . brn/white=line 2 leg of 220 volt.110volt furnace is black to black=cool speed blue unused(tape/wirenut end)red to red=heat speed white/brn to white=common brn/white unused(tape/wirenut end).Blue can be used instead of red if you want more airflow on call for heat.Just tape off red wire.

Hello, Typically your common wire will be white, high speed- black, medium speed- yellow, medium low-blue, red- low. The motor could still run for a short time if it was wired wrong but will either trip a breaker or go off on it;s overload when it's gets hot.

To have your work constantly the fan or the board has a problem communicating with the new fan or if outdoor unit's fan will have to connect to the capacitor, the end looked the thermistor of the room ..
