Replacing a inducer motor on a kenmore forced air furnace

Hello. I'm trying to replace a inducer motor on a Kenmore furnace. I don't have the model number or serial number but I do have the old partnumber of the part I'm replacing if that helps. It is 1013866. The problem I'm having is that the old fan is a two speed and the new fan is a one speed. I tryed hooking up the new one in what i assume would be the high speed wire (black) and the furnace comes on for 30 seconds then shuts off and starts blinking the troubleshooting light. I tryed hooking up the low speed (red) wire and it doesn't fire at all. There were no directions with the new part so I'm wondering if there is some special way you have to hook up the new motor to get it to work. Thank you

Thank you for using Manage My Life. It doesn't sound like you're trying to replace the inducer motor, rather you are trying to replace the blower motor. The inducer motor is the exhaust motor while the blower motor is the motor that drives the air through the duct work.

There are no single speed direct drive blower motors. They always have at least two speeds at a minimum. The most common combinations are Black (high), Blue (medium), Yellow (Med. Low), Red (Low). Extremely old wall furnaces usually had two speeds. High (black) and Low (red).

Sounds like you may have it wired incorrectly. Without a model number, I can't pull up the diagram of the board. You would need to look at the control board and look for the blower relay labeled HI or COOL and attach the black wire there. The terminal labeled LOW or HEAT should have the red wire attached. The other wires (if there are blue and yellow wires) will go to the terminals labeled SPARE unless there are other specified terminals on the control board. The white wire is the neutral and should go exactly where the original neutral wire was.

If you are connecting the black wire to the heating terminal, the heat exchanger will never heat up and will trip on safety. If you are using the red wire for heating and it trips on safety, then you will need to use the next highest speed that isn't high speed. I would also check for a restriction in the duct work such as a pinched duct or too many closed registers.
