Just turn the capacitor around. If that doesnt work, just yell real loudly, "Hey blower, turn around". Then say, "Bite Me". Bubba

: You have the polarity wrong which means you didnt put the wires on it right. You have Hot and common backwards.

Hehehehehehehe....

Evidently they mistakenly sold you a sucker instead of a blower, reversing the polarity will probably fix that. It's a Comfort Taker... often sold to suckers, (sometimes given at a discount to blowers)

Call the tech who installed it. Needs rewiring.

How many wires are there into the motor?

If there are just four then connect the capacitor accross the other two wires which are right now propably commoned up. Then common the two that were connected across the capacitor.

The capacitor must be in series with the highest resistance winding.

I can't believe you just posted what you typed above!!!!!

Then two brown wires to the capacitor. Now look for the two sets (4 wires) that should be sticking partly out of the motor... Likely different not matching colors... Then switch that pairing, or disconnect one wire and connect to the other and again with what's left... Those wires determine rotational direction. Boom!
