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

for somebody to jump the fuse it tells me there is a low voltage wiring problem. likely have a bad tstat wire somewhere. blower not turning on in auto usually means you have a G wire hooked up to the tstat and the tstat is set for gas heat, needs to be set to electric heat when G wire in place. there's a good start, NEW TSTAT WIRE and proper settings
The capacitor in that unit is for starting the motor that drives the blower fan. It has no impact on the ignition of the gas burner. On the control board, there is a light that should be flashing, can you tell us how many times it is flashing?
Watch your furnace when you turn the thermostat up...make sure to record everything that it is doing. If you have an induced draft, forced air system, then the heat sequence of order should go like this... Initial call for heat from tstat, Inducer vent motor turns on-pulls in the pressure switch, circuit board sends power to igniter whether it is spark or hot surface, then gas valve opens. Flame sensor senses flame, burner stays on, and blower motor kicks in to heat the space. If you notice any variance from this, then something needs to be checked by an HVAC Service Tech.
Hi check out the flame senser is clean also jump ou tthe pressure switch see if it lights when you do this , igntion modul is just a box with some push on wires just get the right one the info is all on the module
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.
sounds like you shorted out the heat anticipator in the tstat. try jumping red to white at the tstat wiring terminal and have a friend stand near the furnace to see if it cranks up immediately. if it does the problem is more than likely in your tstat. be sure to blow out any dust in the workings of your tstat. this is 24 volts and shouldn't hurt you but try not to short it out to the common or other wires.
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
