    Hmmm Bruce, I'm thinking trusting a competent service tech, probably ain't a bad way to go.

    I don't think anybody would have figured it out...

    It turned out to be as simple as the 'vacuum' hose was cracked and needed a 1/2" cut off the end and to eliminate the crack. The tech didn't even notice it until the hose fell on his head LITERALLY!

    I thought about cutting that hose off and slipping it back on when I started having problems but didn't think it would really matter...Oh well!

    The tech agreed, they are overly simple and unless a switch is going out, there aren't many things that can go wrong. So far, I've had a dirty flame sensor and a cracked hose, two EASY fixes...

    Yeah, you got that right Mike. I had two calls this season for short cycling on Colemans. One was a 2000 but both had techs out to check them out and one replaced the HSI, control valve and flame sensor. Finally gave up and blamed the problem on gas pressure problems. Told the customer to call the utility company, thats where I came in and found a spider web in the orfice. I fired it and right away knew the orfice was restricted. The flame wasn't big enough to come in contact with the flame rod. The tech had to have taken the orfice out to change the valve and missed it. The other was a no heat complaint, same senerio. I don't know how those damn things get in there but the do. Not saying this is the problem, but it's a condition to be checked.
    See you soon Mike!
