As stated I have a Coleman eb12eb 4 speed furnace 39,000 btus. I live in a three bedroom, 2 bath single wide trailer and this furnace does not keep this little trailer cool. Throughout the day it’s stays in high 80’s in the House with the thermostat set to 70. Is there anything I can do to make it cool better. I thought about increasing the blower speed. The wires coming from the inside blower are black, red, blue, yellow and orange. As of now I have the black and blue wire connected. From what I’ve read this will give you the fastest blower speed. But nothing has changed, not the coolness in the house nor the air blowing from the vents. Do I have it connected wrong? Any help would be greatly appreciated.
