coleman evcon presidential wiring/heat issues
Posted: Tue Oct 23, 2007 4:34 pm
I have a coleman evcon presidential heater.
Turned heat on for the first time yesterday and the
ignition sequence went fine but the fan did not start.
After a short while I expect the high temp sensor
switched it off.
Finally I used the Fan Off On swith inside and set it to on
and the fan started and the burner remained lit.
Later I had a play again and nothing lights now.
There is now a loose blue wire coming from the thermostat
which is hot because it sparked when I accidently touched it
on part of the furnace casing.
I have yellow, tan, blue, green, and red wires from the
thermostat.
Blue is on RC
Green on G
White on W
Yellow on Y
Red on RC and jumped to RH
In the furnace section
White to White
Red to Red
Green to Gray
Yellow to yellow
Blue to - nothing right now.
So right now if i call for heat on the thermostat the furnace starts
(sounds like a small fan )but no ignition.
Any ideas. I can send a pic
