Re: No model number...
If this is a split system, look on the side of the furnace, no luck? remove the front panel. look for a little plate or sticker label inside there somewhere. If you are in California, there is a Goodman (A.K.A.) Janitrol, in Ontario CA. They may be able to help. (sorry don't remember phone #)

good luck, what parts do u need, most of them can be re placed with other furnace name brands, like ignitor, blower motor, gas valve, pressure switch, ignitor board, transformer, ventor motor, they have replacement for all those parts, remember most companies use the same parts
I would suspect that your fan motor burned out. What I would suggest is wait about 1/2 hour with thermostat turned down to lowest setting where it is not trying to turn furnace on. I would then turn thermostat back up to call for heat and see what happens. Most electric motors have a thermal overload on them and if its on motor will not run until it cools back down. Even if this works I would recommend that you have motor replaced and clean blower. Hope this helps. Thanks
Rheem and Ruud are the same equipment, so look on line for a supplier of either brand, they just have the first number of the model number that is different.
What do you mean, when you say, gas blower tube?
heat exchanger, inducer draft motor?
Give me a shout back and let me know.
check for manual reset switches around burner area. These switches will have two wires going to them and a little button in the middle of the switch. You might hear a little click if they were tripped.
remove the blower unit it slides out on some gas furnaces you may have a control bord in the way if you dont have a goodman motor you will need a belly band to clamp to new motor to provide the mounting arms also after loosening the shaft set screw spray w wd40 turn on side and shake motor should fall out if gas furn 115v motor hope this helps
double check your wiring. R terminal on the furnace will provide 24 volts to the t-stat. W terminal in the t-stat will send 24 volts back to the furnace W terminal to turn on the heat. G terminal in the t-stat will send power to the G terminal in the furnace when the t-stat is switched to fan on. Y terminal in the t-stat will send power to the Y terminal in the furnace which in turn will send 24 volts to the A/C outside. The C terminal in the furnace should be connected to the c terminal in the A/C outside as well as to the T-stat. Check the fuse again
Ok, a flashing 3 on a Goodman control board usually means that the pressure switch is tripping. A few things will cause this. One being a restriction in the exhaust or combustion air inlet. The second could indicate a faulty inducer blower motor and the third would be a blocked or bad pressure switch. With the front cover off and door switch taped down, Have a helper turn the thermostat up to 75. You will be watching the circuit board for flashing lights and in a few seconds the inducer motor (the small fan hooked to the exhaust) will start. If this does not happen, we either have a bad circuit board or blower motor. If the fan starts rotating, inspect the hoses going to the small circular pressure switch. Sometimes they may get either water or debris in the hose and not allow the switch to sense pressure. If the hoses look OK, the igniter will glow an orange color and you will see this if you look thru the small viewing port. IF no glow, you could have a bad pressure switch, a bad ignition relay (found on the circuit board) or a bad igniter. OK so if the igniter glows, a few seconds later the gas valve should click open and send gas to the burners. The orange will turn to blue. If this does not happen, you have either a bad gas valve or bad circuit board. Finally if you get flame but it will not stay lit more than a few seconds, you may have a restriction in the burner gas train, a bad gas valve, a dirty or bad flame sensor or not enough gas pressure. Knowing the sequence of operation will give you the needed information to talk with a service technician and cut down on diagnostic costs. Try looking on the back of the furnace access panel for both model number and a diagnostic schematic. This will confirm what the flashing 3 code means for your unit. Sorry, without knowing the model number, this is the best I can do for you. Good Luck!
