Goodman Furnace has a red light that blinks 3 times & won't come on?

im not sure which code your control board is flashing. it could be reverse polarity. make sure the white and black wires coming in are hooked up properly.it could be a limit switch that needs to be reset, make sure you check the one in the blower housing,push in on the red button.you may have turned the gas off and the furnace tried to light three times and failed and it is in lockout mode.turn off the power and turn it back on and see if that does it. the diagnostic chart should be on the door panel. also if you have a 90 plus furnace(you can tell a 90 plus by the pvc flue pipe) make sure you didnt knock off or kink the hoses going to the pressure switches. hope this helps

Goodman Gas Furnace Troubleshooting

I cannot remember without the panel that has the codes listed. I am a heating contractor in Houston so I will give you some things to check. Check the wiring again and make sure that all the safety limits are wired in. The control board checks that all safeties have a series connection with continuity. Check the orange or black rubber tube that connects to the induced draft motor in the burner section area. This tube is the 'proving' switch for tthe motor and ignition will not take place without pfoof of motor operation. Double check those wires on the pressure switch associated with this tube. Turn the 115v power off then back on. This resets the saftey trip code. It will reappear if the safety problem is still there. Remember that the blower compartment must be in place for the power to be present to start the unit. These newer furnace have door switches on the blower compartment doors. Good luck. E-mail me if this does not work. I will try to find out what the code is until then.

Goodman Furnace has a red light that blinks 3 times & won't come on?

I recently cleaned my furnace & after connecting all wires & turning on I realized I had connected 2 wires wrong, fixed them & furnace still doesn't work. NO POWER, NO GAS, NOTHING. There is a red light that blinks 3 times. What does this mean. There is no code chart, that I can find. Can...

I suggest looking in you phone book for a local Goodman furnace dealer.Write down your serial and model number and give them a call. Tell them that you have a red light blinking three times and maybe they can look up the code for your furnace. Also you said the furnace has no power. Just a suggestion,but have you tried looking in your fuse box for a tripped breaker or a blown fuse. Maybe when you switched the wires it tripped a breaker. Just an afterthought. Good luck!

Here is my experience today:

My Goodman furnace blinks code 3 times which is the pressure switch closed. Turn on the furnace, increase temperature in the thermostat, nothing work. The inducer motor does not work.

First I changed the pressure switch, nothing happened, still quiet.

Then I changed the inducer motor, turn on the furnace, finally it works perfectly.

As the results, I checked all the vent, hose and the nipple at the inducer motor it was not block.

The culprit is the inducer motor got burn not the bearing. Hope it helps. Good Lucks!

Goodman Heater

There is usually a code on the door, however you may try turning the power off at the fused switch on the furnace for five minutes then turn it back on to reset a lockout. Also call a Goodman or Amana furnace dealer.

I went to their website. It didn't seem that they had any troubleshooting information available.

Turn off the circuit breaker and re-check your wiring. (Not sure why any wires needed to be disconnected for cleaning?) Turn the breaker back on, make sure your emergency shut off switch (if you have one) is on. Plus any switch on the heater for service purposes is on. Press any reset button. Usually will be lablelled as such or will be a red or yellow button.

The gas control module should have pilot lighting or other instructions if it is electric start.

If none of this works, perhaps the control circuit got fried during the wire cross?

This may be a question of resetting your computer / programable chip? RE-Setting a computer chip usually requires that you turn off the furnace for at least 45 - 60 seconds. If this does not work, please call your licensed and insured service company- immediately. Please do not do anything else as any tampering with this system MAY void your warranty and cost you a good deal more than you expected. Best Wishes Wayne
