    My honeywell thermostat cant seem to communicate with the cbx26uh air handler and blowers will not turn on... system sits there and does nothing.

    I have a Lennox 10 year old Air Conditioner in my Condo and the Blower is not turning on.  But if I open the unit up and give the blower a spin, it runs fine, just wouldn't startup on its own.  any ideas or help would be greatly appreciated.
    Thank you

Do you mean the air handler fan doesn't run but the outside part runs? If that is the problem, try turning the fan blade with a stick. If it turns freely, you have an electrical problem. It could be a relay, a bad motor winding, a bad capacitor, or a bad thermostat, among other things. If the fan won't turn, the motor needs to be replaced.

We have royal red furnace to heat our home.The fan dose not stop.


Details.......does the furnace function normally otherwise? Might just be a stuck fan switch. Make sure the thermostat hasn't been set on Fan ON setting or summer air circ. on older furnaces.
Find the fan switch and tap it and see if fan quits. If it does,fan switch is bad.probably. Always make sure your air circ. filter(return air to furnace) is replaced every 3 mo. or so,too. don-ohio (:^)

Cooloing is not coming down from room temperature


The unit needs service. Call a technician! You can:
Check your air filters
Clean outdoor coil by turning off all power at breakers and tstat, clean o.d. coil with water hose
Inspect indoor coil (if you can) for build up or debris
Other than that? May be low on freon. A service tech will cost $ BUT not having the unit service will cost more due to electrical consumption and excessive run times shortening the life of the system.

Electric Furnace stopped running


You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.

Why can't I lower my honeywell 8500 below 67 on cool?


With a two story house you have to be aware that cold air flows downwards so any cold air coming from an ac unit will flow downstairs( normally down the stairway) so unless you can close off the down stairs then the up stairs unit will be cooling downstairs as well. Ac units have a thermostat located in the air intake and it cools until the cold air has risen to that point. In effect the space above the ac unit will be hotter than the floor. Knowing how they work ,you can see that the upstairs unit will never reach the set temperature because the cold air is continually heating from the house and will never get to the top thermostat.
So your solutions are
1-- fit controls that restrict the cold air from leaving the upper floor (Doors)
2--don't run the upper ac unit unless you are living up there (waste of money
)3 place an ac in each upper room and keep the room door closed

Why does home central air conditioner will only cool to 80 degrees?


Because it is low on Freon. Do not run it low or the compressor wont be able to cool and you will burn it up. If it has run more than 1 hour in 90 degree heat the compressor is probably already damaged. Have a HVAC professional look at it, but if you were still using id plan for the worse, a complete replacement.
