Ct87n thermstat is hooked up and the heater is on because i smell the heat but it is not blowing out the vent


The blower motor isn't running. At the thermostat, red wire to the R terminal white wire to W terminal.or W2 If the blower still doesn't run It's probably not the thermostat.

Honeywell thermostat blows cold air on heat


Thermostats don't actually blow anything, the heating system might though. Check the breakers for your heat system, then call a heating specialist. They're really not that expensive.

You can check your float switch, power to both the air handler and outside condensing unit and ensure power is present, also check control voltage from transformer ensure 24Volts on secondary side. If you are not comfortable around electricity though I recommend you call your A/C Contractor for safety reasons.

Further information would be needed to further diagnose your problem.

Check for a fuse in your AC/Heating system either on the control board or in-line on a wire. Make sure the wires are correct to the thermostat.

Central honeywell air conditioner


Sounds like it may have lost power. Check the breaker and the fuse at the furnace. If they are all in the on position and working then it sounds like you may need a technician. If the display is blank on the thermostat you may also want to replace the batteries.
