So we changed out the Coleman Mach standard Rockwood thermostat to a Honeywell focus pro 5000 non-programmable digital thermostat. It installed perfectly fine except that we had only one speed for the fan. Having to speed is required a switch to be installed which we did not have at the time. Then we went back and follow the instructions to install the switch and when we did so the fan turned on for a second and shut off and now we have no fan at all. We have even tried going back to no switch like the original upgrade installation. And still the fan does not work.
Hoping somebody has an idea other than checking the fuses which we have done. The only fuse box we can find is below the fridge. There isnít another hidden one is there? Also our air conditioner is also a Coleman Mach.
Thanks in advance.
Yes exactly how we wired it. The fan for the heat works fine. When he hooked it up the fan for the a/c started for about a second then stopped and won’t come on again.
Checked the fuse box all good. He looked in the a/c and couldn’t find any hidden fuses.
So after checking wiring again he took the green fan speed wire and touched it to the red power line and the a/c fan turned on.
So, it’s obviously a problem with the thermostat and we’ll be returning it and getting a new one.
He took the fan wire and hooked it up to the power wire and the fan worked. So he then deduced that it was a faulty thermostat. That was definitely the case as we have bought a new Honeywell programmable one (as the same model was not available in the store I had bought it on Amazon). Itís been installed and works perfectly.
