Just to understand what you are saying; You are hooking a wire between the R terminal & the G terminal on the fan control board and the fan runs. When you turn the fan on by the thermostat is does not.

Assuming that you have 24 volts at the G terminal (or wire) at the air handler/furnace when the fan does not run, I would have to say, based on the information that I have been given, that you have a bad fan control board.

My porsche boxster 2001 is over heating and red light blinking


More than likely the cooling fans or fan for the engine is not working, ether because of a fuse or the fan its self or the temp sensor that controls the relay for the fan. So first check fuse, then check the relay, then if those two are ok, then hook power and ground to cooling fan, if fan operates then ether the wire from fan to control temp sensor is open, or the coolant temp sensor if open, faulty, sense fan is not working this causing the a/c to be inop and the over heating of engine , but only at stop and go traffic do to the lost of air flow across a/c condenser and radiator.

I have a Honeywell CT87K thermostat. I wish to REVERSE it's functionality


Your existing thermostat is not capable of doing what you want it to. Instead, install a "heating and AC" type thermostat, and hook your fan to the AC (cooling) side.

Inside fan does not blow on auto or fan only.outside ac will work if i push in the relay switch


So you have no 24 volts. Either float switch is tripped, transformer or fuse bad, or your tstat is bad. Turn power off to indoor unit. Open tstat and wire red green and yellow together. Turn power back on. Let me know...

I installed a Honeywell RTH230B model thermostat. The heat works fine, but the AC is blowing warm air. Wires from old system are as follows: Y=yellow; G=green; R=red; O=brown; C=blue; E=white (it looked...


the colors of old system are for heat pump.if you have a heat pump you need heat pump thurmostat and colrs will make more sense.if not,then you need to go into furnace to see what colors go where.yellow is cool, goes to compressor contactor,usually another wire going from furnace to outside unit.green is fan relay rh is heat call rc is cool call

Thermostat Wiring Problems!!!


. your blue is probably common and if you hooked it to Y you shorted the transformer or blew the low voltage fuse. Green is fan, yellow is AC, Red is 24volt. Is it a heatpump or just ac? I think its probably a heat pump and your brown is your Reversing valve it needs to be hooked to O on the new stat. If its a heatpump your tstat must be a 2heat 1 cool stat w/ aux heat. Without knowing what terminals the wire were hooked to on the old stat you may have to look at whats hooked up at airhandler( furnace) and on A/C (heatpump) tobe able to determine what goes where on the new one.

The on/auto switch is for the fan only on is continuous, auto is just when the t-stat calls for cool. If it works in on possition that means its getting power to the t-stat but does nothing in cool & auto then its your t-stat. $19.95 a wal-mart. probably four wires like this. screws are marked G-R-W-Y. You can do it.
Green-G
Red-R
White -W
Blue or yellow-Y

Honeywell VisionPro TH8110R1008 controlling a Carrier FA4ANF018 electric furnace/AC. Heater won't turn on. Honeywell VisionPro TH8110R1008 controlling a Carrier FA4ANF018 electric furnace/AC. As best I can recollect, the sequence of events went like this: Furnace was working normally. Thermostat was set at 70. Turned temperature on thermostat down to 67 and left the apartment. Didn't notice if furnace was running or not at the time, nor if it was running and shut off when I lowered the temp. Came back an hour later. Furnace was running and temp was up to 72 degrees. Thermostat looked normal. No indication of low batteries. Tried turning the system off on the thermostat. Furnace continued to run. Nothing on the thermostat would affect the furnace. Eventually turned off the circuit breaker (for the apartment electrical, not the breaker on the furnace) to stop furnace. Waited. Turned breaker on. Furnace stayed off. Batteries failed in thermostat and screen went dark with barely readable failing battery message. Put in new batteries. Thermostat fired up but still wouldn't control the furnace. Switched to cooling. AC went on. Couldn't turn AC off. Had to turn breaker off again. Turned breaker on. Thermostat displayed "Wait" message when I tried turning on the furnace. Waited half an hour. Wait message disappeared. Still can't turn furnace on. Slid out lithium backup battery and slid back. Thermostat makes appropriate click sounds as if it is turning the furnace on or off, but furnace doesn't respond. Equipment Status screen shows furnace on or off depending on thermostat settings. Set thermostat to System Off. Checked breaker on side of furnace. Was off. Turned on. Turned temp up on thermostat. Thermostat clicked, but furnace did not go on.
