Atwood furnace would not start

Used it once at home to test. A second time out camping. Then only warm nights or with electricity.

Yesterday out by the lake no electricity and no furnace! No blower at all. Red blinking light tells me limit switch or airflow problem.

I am thinking blower does not even come on; must be dead motor so no airflow.

Turns out it was the limit switch. It will prevent even motor from turning. 30$ part + 50$ labor.
