Nothing functions on the unit not the a/c nor the heater, I've replaced the tstat,spark ignition module with the gas valve,the contacter, and the step down transformer. It does'nt have a circuit board so there is no led's blinking. And if this helps any the Model # 585HJ024040

If you have gas furnace, the outside unit will not come on unless you have dual fuel/ gas and heat pump. If you can look at wires in thermostat, if you have no wires going to O or B then you don't have heat pump. Normal tstat wiring for gas furnace and air conditioner. R,W,G,Y and maybe C.
MOST UNITS NOT HEAT PUMPS WIRE UP WITH 2 WIRES TO CONDENSER RED WIRE AND WHITE . WHITE GOES TO COMMON C ON FURNACE AND RED TO Y TERMINAL OF FURNACE Y ALSO GOES TO Y ON TSTAT. BOTH YELLOW WIRES MUST MEET AT Y OF FURNACE. WHITE FROM STAT TO W GREEN FROM TSTAT TO G AT FURNACE IF YOU HAVE C ON TSTAT HOOK UP BROWN WIRE OR BLUE FROM COMMON TERMINAL WHERE YOU HOOKED UP CONDENSER WHITE WIRE AT FURNACE TO TSTAT , MOST THERMOSTATS DONT NEED C RUN FROM FURNACE. THE TWO WIRES GOING TO CONDENSER IS - AND + TO ACTAVATE CONTACTOR IN OUTSIDE UNIT
HI; I need more info. How old is the equipment. name brand of equipment. Also to answer Your question ...Yes the tstat wire goes into the furnace to make several connections then a seperate cable(brown) will follow Your freon lines out to the condensor.Also try removing the cover and have a good light. Get someone to turn on heat at tstat and watch for clicking sound.Sounds like You have a spark assist pilot system. When the sparking starts the pilot light should come on. Then once the pilot sensor feels the heat comming from pilot light it will allow the gas valve to come on...BE CAREFULL...I ASSUME NO RESPONSABILITY FOR YOUR ACTIONS...alpharome416 PS.usually there is nothing to worry about just keep Your space to begin with ok.
the fan you hear come on at a call for heat is most likely just the inducer motor. the click you hear is probably the relay for the hot surface ignitor which should glow red, then in turn ignite the main burners. your going to have to determine if the ignitor is coming on. if it isnt the ignitor is bad and will need to be replaced. if it comes on and than shuts off after a few seconds the ifc board is probably at fault
It sounds like you might have a spark igniter on the unit that is being told to relight the burners. This is probably the tstat as this is the only control that "tells" the unit to come on. There isn't anything else internally that will cause this problem. Replace your tstat and I bet this solves your problem.
No, Payne is a cheap Carrier unit. Keep track of your wires and what terminals they are attached to. Usually, units are either a 4 wire or 5 wire setup. In either of these the R terminal is your 24v power, G term is your fan, W is your heat, and Y is your cool. Some times there is a 5 wire which is your common. You use a common if your thermostat isn't powered by a battery. On the R terminal, they are usually marked RC/RH and have a jumper between them. The only time you should remove the jumper is in a 5 wire set up. RC refers to the common and RH refers to Hot or power. Make sure that when you are installing the new tstat there is usually a very small switch that you change for either an electric unit or a gas unit. Change according to what you have. As long as you keep track of your colors and terminals on your old tstat, you won't have to open up your unit to see where the wires are terminating. Good luck to you!
the tstat sounds like it is not connecting the white and red terminals which is usually the heat cycle if it is a gas furnace if so to check I take tstat cover off and jump white terminal to red terminal this is the standard heat position the unit should fire the heat cycle if not a gas funace let me know what type of unit you have hope this helps
pull the fuses and check voltage line to line with the fuses out you should have 208 to 240 volts if you have 50 or so volts try line to ground if you have 120 on one leg it will back feed with the fuses in,because of the windings involved. in any case you are missing one leg somewhere to get the voltage readings that you have poasted
If your running gas heat it's 5/8 3/8 tubing.If it's elec. heat it's 3/4 3/8 tubing. Etheirway 3/4 3/8 works for both. Use 6 wire for tstat from tstat to furnace or air handler, and you need is 2 wire from condensing unit [outside] to furnace or air handler or anything more than two.
