Hi, this is more than likely a problem with the fan control in the furance, to check for that all you need do is remove the green wire from the thermosat, and see if th eproblem still exists, if ti does then its the fan control in the furance and nto the thermostat, let me knwo, thanks Mark, if this is a new themrostat install then its more than likely a problem in the setup of the thermostat, let me know what happens when you remove the green wire all together,
Hi, ok the problem is most likely in the setup of the thermostat, so let the heat run and see if the fan will come on when the unit heats up, let me know then we'll move on to the thermostat setup.
Make sure that the dipswitches are both on and the the fuel switch is on F
leave the 3rd swtich off to see farenheit temperatures, so its 1 & 2 On and 3 off, then the fuel switch to F
Ok put the green wire back on and try it, the switch being on E will turn the fan on in heating, because the stat thinks it's electric heat and the fan will always run with electric heat energized, now that it's set to F which is gas heat the stat should let the thermostat control the fan in the heating mode, let me know what happens, thanks Mark
If it reads celsius switch the 3rd one,
It's better to do that,
Ok let it cool down a bit,
lol, no you fixed it.
