I'm having trouble with my furnace. The fan seems to work fine. The air temp isn't constant though. It's the right temp sometimes; then barely warm other times; and almost cool others. At anytime during the cycle the air can be any temp. Anybody have any ideas on what I can do? Thanks for your time

Could be a faulty sequencer contacts opening and closing intermittantly.
That would be first suspect.
Thanks,
Robert

Thanks Robert; I appreciate the info and quick reply. Not being very knowledgeable on this subject, with a very limited budget, I'm wondering if I could find the sequencer, and what I could do to fix it? I have no manual and using google, found no place on the net to view one. I appreciate your time. Thanks again.

Sequencer # 3115-3571 @ $39.99 + $6.75 shipping .
You can see and order it from right side of page here through Paypal:
http://www.mobilehomerepair.com/ColemanElec.html
Click on pic for enlarged view.
OR, order by calling toll free between 9AM/5PM CST Mon thru Fri to
1-877-263-7860 and charging to Visa or Mastercard.
It is located beside transformer and above elements in controls area.
You remove wires one at a time (turn power OFF first) and reconnect to new sequencer.
Then remove screws and remove sequencer and remount new one.
The top and middle silver terminals are designated M1-M2, M3-M4 and M5-M6
Bottom brass terminals are H1-H2 and H3-H4 .
That would be most likely cause, but can't gaurantee as I'm not there to test.
Added ordering info needed if you're in Canada, let us know.
Thanks,
Robert
