mobile home Coleman furnace problem

[aplusmhs]

i have a coleman evcon m.h. furnace. model dgat070bdc.
it has an ignition control module. the ignitor glows red, the main burner comes on, then shuts down. the blower does not come on. sometimes if i turn it off and wait 10 minutes or so, the blower does come on. i have replaced the thermostat and ignition module to no avail. what else should i be looking for?
thank you, dale

Hi Dale,

Trace two blower wires, either low or med low speed and common wires.


See if they are receiving 120vac across them to motor.



Thanks,
Robert
