Re: Furnace anticipator

Except for the only occasional on and off before staying on, it seems to be working fine.727Views0likes0CommentsRe: Furnace anticipator

I was worried that this would screw something up. This would seem to me to be a pretty good indication you have an issue with the furnace itself, particularly if it's worked properly up 'til now, in which case fudging the thermo anticipator would hardly be the correct solution. It seemed to help, though. Before it was false-starting, if you will, four or five times before staying on. Now, it only does one false start before staying on sometimes. I'm thinking of trying a higher setting yet, to see if it goes away completely.727Views0likes0CommentsRe: Furnace anticipator

Just set the tstat at 68 degrees and forget attempting to adjust the Anticipator. Sorry, but this type problem is NOT a problem. Just people trying to waste their time obsessing over something. In 38 years as a tech, I have NEVER had to or had a customer state he seemed to have a problem with the furnace that required the anticipator be adjusted. Also, since the majority of Wall RV tstats are electronic, that stops this type problem and has for over 25 years. Doug Well, Doug, the problem is not temp control, but the fact that the furnace was popping on and off, less than a second, a few times before staying on. I was worried that this would screw something up. I set the anticipator to 8, and that seemed to work. However, in the middle of the night, I still heard a second or so of blowing and it would shut off for a couple of seconds, then come on and stay on. Not every time but once in a while. I was thinking of upping the anticiptor a half amp or so, to see if it eliminated the on and off phenomenon.728Views0likes0CommentsRe: Furnace anticipator

Is it set for gas operation? It's a Suburban. With a cheap Chinese control board. At least it used to have a cheap board.291Views0likes0CommentsFurnace anticipator
I had the control board on my furnace replaced, which fixed it, but before that I tried a new thermostat. The new one, like the old, had an adjustable anticipator. This is a little dial on the inside of the thermostat that adjusts the amps, or something. The manual said to set the thermostat anticiptor to .7 amps, which I did. The thing is; my furnace now goes on and off several times sometimes before settling down and running. I tried adjusting the anticipator .05 amps at a time, like the manual says, to .8 and .6, but all settings seem to produce a stutter before the furnace decides to stay on. Should I just try further settings on the anticipator?5.9KViews0likes24Comments
