99% of time it is the Fan switch. How long does it run before it shuts down. Russ
Customer: replied 1 year ago.
It burns for about 30seconds then it shuts off. It cycles and relights but the fan never comes on so it just continues until i turn the furnace off.

That is an older furnace. Contacted Mobile Home supply. They said on older Nordyne which was sold under Coleman brand. Replace fan relay,limit and fan switch. There reason for this is that if they have never been replaced they need replacing just due to age. The only other thing in series is the fan relay. Has a normally open and closed set of contacts. I work on them often and 99% of time it is just the fan switch. Russ
