SOURCE: Goodman furnace I think

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!

You need to type GOODMAN GAS APPLIANCES into you browser to find you local servicecenter. I must tell you that Goodman only sells to authorized service companies in my experience. So you become EgKraft Company.

SOURCE: goodman gmp075-3 led blinks 5 times

I Also have the same and other problems with my furnace model # GDS80703AXBB. First the LED kept blinking 4 times and I too jumped the primary limit, that didn't kelp. After several attemps I moved the wires going to the circut board and everything starting working again. After a week It stopped working again, so I pulled the plug out of the circut board checked all wires for for a bad connection plugged it back in. Now the LED blinks 6 times again I move the wires. Then the LED blinks 3 times. Then the transformer burns out. I have burned out 2 transformers and I have ordered a new circut board.

SOURCE: constant high pitched noise emitting from furnace

Hi,
This is probably a dry bearing in the vent motor. Those motors run at high RPM's and can make a deafening high pitched squeal if they become dry and need oiling.
Some of the motors have oil cups on them for dripping oil into and others;s are much more difficult as you need to guess where the bearing is and try to drip oil down into them or run the oil to them.
Any light weight small motor oil ike a sewr machine oil will work.
Many hardwares have small oil bottles with extending spouts made just for oiling motors for just a couple of bucks...

The other thing that can cause this is if the blower wheel is coming loose and has moved to the side and is hitting the side of the blower housing. Take the bottom cover off and check for play or movement side to side in the blower wheel. Spinning it with the power off by hand may give you a clue as you will hear it scraping the side of the housing.

I can't find any info on my Goodman furnace.It's a GMP and the model number on the front of it doesn't match any goodman model numbers G2FD036S17A......I'm lost


Take the top panel off and on the inside of the left side of furnace as you are facing it should have a nameplate rating.

The nameplate rating should have the model number and serial number of the actual unit that you have.
It will list BTUS/Electrical Amps.

Please tell me the date of manufacture for Goodman CAP3636C6AA


You will need to post the serial number. The model number does tell me that you have a painted case, three ton coil with a fixed metering device installed, and it fits a 21" furnace or air handler. The first four numbers of the serial number will give the manufacturing date.
