Can't get the gas furnace to heat.


All York/JCI thermostats made by Venstar

The setup is probably incomplete. Did you configure the thermostat for a 2 stage heat pump? The heat pump should have a thermostat wire connected to R, C, Y1, Y2, and O, that makes 5 wires. I suspect you are only using first stage compression and or first stage blower speed.

My old thermostat has only yellow and red wires...no green and white like my new Honeywell thermostat installation instructions mention. Is this a problem?


The green wire is used to turn on the blower if you want constant air circulation. For heat only, the red and yellow wire will work as long as they are connected to R and W terminals on heating unit (or TH and TW on some models).

New thermostat not cooling. Blowing heat instead.


Hello You have only 5 wires? multi stage if so ,is run by something else.Check that RH/RC is jumped out on new stat.Also check that O is not on the B terminal.If there is an A/B select switch set it to O.Emergency heat button dont matter as there is no wire to run it with only 5 wires.

WONT HEAT. BLOWER COMES ON BUT NO HEAT. IT HAS NO


I'm assuming that this is a portable heater. If not let me know. If it is it sounds like the heating coil is bad or the relay which turns on the heat is not working. TU probably means turn up the thermostat. I guess you could try that but it seems pretty obvious. Let me know how you make out.

Honeywell thermostat TH6110D1021. Blower comes on


Hi, You are right, fan is on a time delay in the heating cycle, and after burners fire that is when this delay comes into play. You have a preset factory temperature that determines the cycle on time for the fan, and the off time after the burners shut down also. This will not be in the thermostat, but in the fan/limit control the is mounted on the face of the furnace, with a probe inserted into the fire box.Depending on how old or new this unit is, will depend on the type control you have.It may be just a high limit switch, or the 1st I mentioned.If so, It rotates in the burner as the temperature rises, to turn the fan on and off.Disconnect power, remove cover, and 2 screws.Slowly remove the control and gently clean the probe. Turn the dial if this one has it and you will be able to hear it click. This click is contacts closing to start fan operation.Reinsert and try again. If problem continues, you will have to replace it.They do tend to stick closed/on, in the heat cycle from time to time and a cleaning sometimes will solve this problem. Not knowing how old this furnace is and type, make it difficult to give you a correct diagnosis, so check this fan control as I have explained, and if your system is of a different type, please let me no so I can correct this problem. Sincerely,

Blower stays on with new themostat


Check to see if there is a short between the green wire and the red wire. Green is the fan control wire for AC. Sounds like some wires may be touching. How did the old t-stat get fried?

Blower not working with new thermostat


To get the fan to work, look at the heating system to see what termoinal the blue wire is connected to. It should be the "G" terminal. If so, connect the blue wire to the "G" terminal on the thermostat and then manualy switch the thermostat to "Fan On". Indicate what terminals you have on your new thermonsta ie "G" "R" "Y" "C" "W" etc... For a fan to work, typically you connect "R" to "G" on the furnace.

Honeywell CT3611 thermostat, not working..


if you cross the two wires and you see a slight spark and heat comes on, then the problem is in the thermostat, if not then problem is at furnace it self.
