Atwood furnace won't start

[Stan&Jacquie]

What's the best way to trouble shoot a furnace. Mine will not start. It's an 8500-IV series in my Monaco coach. I replaced a board in it last fall when I had a similar problem and that fixed it for the short term. Seems to happen on rainy days.

What does it do when you turn it on? Does the blower blo, but the burner does not ignite? Details....

Hey....thanks for your response! It would do nothing. I went inside the unit and checked the power connections at the on/off switch that is attached to the motor. A connection must have been loose because the unit came on after I recrimped and cleaned up the connectors. Unit is running fine now. Thanks again!
