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
hello sir, Please provide the following information so that your issue may be diagnosed properly,what is it? brand name,complete model number The problem, What is happening with what? When it is happening? Are there times it does not happen? Did it just start happening? Did it ever work ? Did any seemingly unrelated event coincide with whatever it is not working? need the model number and brand name, if you need a manual i need the brand name and model number,if it is a riding mower the model number is under the seat.a snow blower the model number is on the rear of the machine, let me know,thank you. ``
All Amana and most other brands have a five year parts warranty, without the model number I would have to say either the thermostat, control wiring which sends a signal to the G terminal may not be working or the blower motor is bad or jammed up.
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.
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!
