Nordyne M1MB increase fan speed?
Posted: Sat Jul 07, 2012 8:29 pm
I have a Nordyne M1MB 077a (A/C ready, up to 3 ton.)
While I don't have central A/C yet, I do have a couple small window A/C units.
I thought maybe I should run the furnace fan to circulate it through the house, and what do you know, it does make a very noticable difference. I had to hook up the green wire to the thermostat and now I can turn it on and off.
Is it possible to increase the fan speed? I think it's running on low or medium-low speed. I do have the manual but it's not explicitly clear on what to hook it up to. I see the black wire is the high speed wire for the fan, but it is tied off and dangling in the furnace. The blue and orange wires are actually hooked up to the circuit board.
The only thing I don't know is which speed the green wire toggles. Is it as simple as unplugging the blue or orange wires and replacing it with the black wire?
