Sounds like the thermostat is set up to control the fan with a call for heat(usualy the way we set up a heat pump system) New thermostat?

Heater does not come on gms80703an

There are too many reasons for this to happen so we would have to narrow it down. The sequence of operation on a Goodman furnace is usually:
1: Inducer draft motor comes on
2: Hot surface ignitor comes on and glows
3: Gas valve opens, lights burners
4: Flame sensor detects flames
5: Blower comes on

If the inducer motor never came on, then you start looking at power to the unit, thermostat issues, or inducer motor issues. Just a few places to start. Hope this helps!

Goodman furnace GMP075-3 The thermostat was in the off position over night and sometime during the night, the induced blower and blower motor came on. The trouble light on board blinks 5 times. I checked...

Need your model # to check the codes but, this coming back on after turning the t-stat off is rare. You may have been in a lockout and the furnace re-started. Some furnaces try to start three times , then lock out. Time out, then re-start. The codes should be on your furnace blower door. Write back with this info and i could help.

I turn the thermastat to heat on my goodman gms90904cxa and the inducer fan does not come on and after a couple of seconds the lights blink 3 times

Hello, a 3 blink pattern indicates a open limit switch. Most of the time a dirty filter, dirty blower wheel, weak blower motor, can cause the limit switch to open.

Goodman furnaces gxs91155dxaa will not start> steady red light on the circut. No inducer motor. Somthing strange when I disconnect the Roll Out sensor the blower motor runs along with the inducer...

I would first try to power up the inducer motor by itself. If this works without any issue than the next step is to look at the circuit board. You will need a multimeter. Set it to 120V AC and test the leads on the circuit board that the inducer motor attach to. Turn the system on and see if you get a reading on the meter, if so, then you know the motor is getting power. I would then check the legend of your furnace with the led pattern. You mention it is steady, look up what the steady light means. It may point to a control board error, in that case you will need to replace the board.

I replaced the combustion inducer motor the new motor runs slow and does not produce enough pressure could something on the board be bad?

Could be. what is the voltage going to the inducer? You might have a bad ground or a polarity problem. Let me know what voltage you have and we will go from there. Does the main blower motor run fine?

Goodman model 135-5 furnace fan and induce motor run all time even with thermostat off. Theermostat and wire were replace

Is there a thermal Fan/Limit switch in this furnace? If so you may need to tweak the low range setting so it can turn off the blower.

My heater does not turns on, the circuit board without fuse, makes the inducer motor work. this is a goodman heater.

if this is a high effeciency model, the venting may not be clear or the drain may be partially plugged. if you hear any sort of water gurgling in the inducer motor, you probably have one of these conditions. if that checks, see if you have 110 volts to the hot surface ignitor. if you read voltage there after the inducer comes up to speed, then you need a new hot surface ignitor. if no voltage, then the pressure switch is still not closing. concentrate on the condensate drain and furnace venting.

Just relpace a seized up inducer motor/flu vent. 3 red blinks

the diagnostic codes should be listed next to the wiring schematic on the inside of the blower compartment door. if the inducer motor was bad I bet you have a tripped flame rollout switch around the burners. look for a very small red button between two wires on a disk around the burners. push on the red button to reset the switck. this should turn your furnace back on.
