The range hood is a "Rangemaster". I don't find any numbers on other than that . It has a two speed motor with with the words UPPCO CHICAGO on the back plate on the motor. It has as plastic or white nylon fan which is about 4 1/2 or 5 inches in diameter.
Can you tell me where I can get a replacement motor for this hood blower. It has three wires, reds, black and white for 2 speed. The range blower also has a hood light, operated by a separate switch. I will appreciate any information you can send me on a replacement motor. Thanks,

The only way to really tell if the blower is set to high is to look at the control board inside the furnace and see how it is hooked up. You will have either a 3 speed or 4 speed blower motor, more than likely a 4. These are Hi, Med Hi, Med Low, Low. Each speed has its own color and if the motor has ever been changed, it could be different from factory diagrams. The most common colors/speeds are:
Black- Hi Blue- Med Hi Orange- Med Low Red- Low
You could have different colors but they will be close. If it's an aftermarket motor, the speeds will be listed on the motor itself, but very difficult to get to sometimes. On the board, you should have terminals marked, COOL, HEAT, PARK, PARK. You hook what speed you want for Cool and Heat and put the other 1 or 2 wires on Park.
Again, these might not be exact, but these are the basics and they usually don't deviate from them to much unless it's a 95% furnace or such. If you do have the diagram for the furnace, you will be able to find everything with no problem now that you have the basics. Also keep in mind that you will have a Common wire from the motor that hooks to Com. terminals on the board. Hope this helps and good look!
On some natural or LP gas furnaces, the blower motor has to come on 1st and then shuts off. This process starts the inital call for heat. If you find yourself without heat and the blower does not run, turn the furnace to on at the thermostat.
When changing the fan to on, you are changing the speed, if the heat comes on, that means you have a burnt out speed on your blower motor.
If nothing happens, change the fan speed at the control board. In some instances they may be using the same blower speed in both the heat and cool mode.
what makes you think there a problem with the blower, Most newer blowers have multi-speeds so be careful to only have two wires hooked up at a time , always have the ground hooked up, usually the white wire and then try black for high speed, make sure fan is secure it may shift. to check low speed connect only the red wire to power and the white wire to gound . depending on motor, other colors would be medium and medium high is so equipped. if motor gets hot after a while check for a capacitor, they have a tendency to get weak, replace with exact same capacitor. let me know why you suspect the blower.
EE8 is for blower motor malfunction. It could be the motor, bearings or the speed sensor.First I would either remove the exhaust pipe from the back of the heater or take the front cover off of the heater and remove the black rubber boot from the fan (easiest). Then use a pencil or screwdriver or something similar to reach into the fan and try to turn it. Carbon builds up on the exhaust fan over time and may cause the fan to stick. Turning may break the carbon loose and free up the fan. If that doesn't get it, you are probably going to need a new blower motor.
EE8 is the code for combustion blower failure. I'm not sure which fan you checked. You can't see the combustion blower fan. It is inside the black plastic cover on the back side of the heater near the bottom. You can see the motor for it from inside the heater. The blower has a sensor to determine fan speed to control the amount of airflow to the burner. There could be a problem with the sensor. When you turn the heater on the first thing you should hear is the combustion blower start up and run. On the smaller heaters they are very quiet and sometimes hard to hear. Start the heater and see if the blower starts. If it doesn't remove the front cover and locate the blower motor so you can check the wires going to it. I have seen wires that mice have chewed off. Otherwise you may need a need blower motor. If it is running then the sensor is possibly bad and you would also need a new blower motor. Also make sure the exhaust pipe isn't blocked since you say the house smells like diesel. Let me know what you find. email@example.com
Most blowers nowadays are a 2-5speed, meaning you can change the blower speeds. You would have
to get into the electrical panel trace the wires out
and take a lower speed tap and exchange it with a
high speed tap.
I would turn the furnace off, locate where the blower motor is, usually near the filter.. If you are capable,
reach in and try to turn the blower wheel. If does not
move, its possible the motor is bad.
If it is a multi-speed blower, change the heat spped to a different speed and see if the breaker trips, if it does then the indoor blower motor is probably bad
The furnace should be a 3 or 4 speed motor in it. On the circuit board there are places maked heat and cool. If you are looking for low the red wire should be plugged into the heat designation. make sure unit is unplugged before changing
Motor speeds on the blower are always remember black is high, blue in med. and red is low sometimes blowers are 4 speeds but the main colors are the black blue and red. Now where to change locate the wires coming from blower to a box or control board. control board has setting for heating and cooling speeds for the blower. You might see blue on heating which would be medium speed so take the red off park terminal and change places with the blue. Now if you have a fan control switch it looks like a dail in the middle of the furnace with numbers on the face with pointers set at the numbers. follow the wires from there to the electrical box and open box. find color of blower and switch be sure to cap off the wire you change. Wire nut would be good.
