Rmove the two screws holding the blower in place and slide it out. With the power off, rotate the wheel and inspect for debris or an impingement. If everything turns easy, you have a bad motor or start capacitor. If you have rubbing, adjust the wheel. If the motor will not turn, replace it.

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 furnace GMPN080-4 Getting 4 RED blinks/Open Limit Swtch

You have a limit switch located in the furnace (a little bigger than a dime and located near the center of the front panel, sometimes the switch is mounted to a small fiberglass board) . There will be two wires going to it. They sometimes trip so often that they fail to automatically reset(due to dirty filters or undersized ductwork). You can SHUT OFF POWER TO THE FURNACE, then remove the two screws holding the switch in the furnace, pull the switch out of the furnace and tap on it and wipe it off.
The switch may work a few more times but should be replaced with the same size and type. You will see some rating printed on the switch somewhere. Write down all the numbers and get a replacemet from a furnace/AC supply house. If you have a meter and know how to use it you could check the switch for continuity.

Sometimes just a tap on the switch will get it going. There will also be a couple of rollout switches that could be tripped. They have little buttons on them to reset them. If they trip it may have other issues to be solved.
Hope this helps!

SOURCE: Goodman GMT115-5B, loud noise when turned on

In the lower portion of the furnace you'll see where the blower housing is hung in the center of the furnace. There are two bolts you'll need to remove to pull out the whole housing. Depending on the size furnace you have you may have to unmount the control board and set it aside. Don't worry there is no need to remove the wires from the board. Once you have the housing out set it on its side (motor side down) and you'll see a shaft where the blower wheel mounts onto the motor shaft. There should be a bolt you can tighten. first loosen the bolt and put the housing right side up. after that center the wheel on the shaft so that neither of the sides of the wheel are rubbing on the housing once you find that spot where the wheel spins without rubbing tighten that bolt on the shaft and reinstall. should the problem persist you may need to replace the blower housing and/or wheel. I doubt the motor will have to be changed.

SOURCE: heater won't heat very long

there isnt a pilot if it has jets , it has a Hot surface ignitor. you should see a glow and then the jets light , if its running for a few min it may be overheating, have you changed the filter recently? you should also have a flash code you can locate when the furnace shut off and is no longer doin what its supposed to look thru the bottom door peep hole and watch for a series of red flashes. if you remove the cover after retrieving the flash code there will be a chart on the inside of the cover that will tell you why the furnace is shutting off. by the way the model # you gave is for the A/C coil above the furnace, not the furnace.

Inducer Motor Noise


Bad induction assembly is common with these units. If it's the style that has the motor install in what looks like a square black plastic box with tube connections off to the left and right. Replace the whole assembly, not just the motor. If you are mechanically inclined replacement isn't to hard.(make sure electricity to furnace is off). Cost to purchase induction assembly(look online) is around $300. If you have a company do it expect a bill between 650 and 800.

I have a goodman furnace that give a rattle and vibration noise througt the vents in the house when the furnace comes on


Check the main blower. Make sure there is no debris stuck in the fan wheel( squirrel cage) or the blower as this can cause the blower to be out of balance and vibrate. Also check the blower wheel for any up and down or sidevto side movement which could indicate a worn motor bearing. Hope this helps.

How can I make the ac quieter inside the house?


If you have hard ducts, you can use some flex duct between the supply plenum and the hard ducts as a way to quiet the noise down.

Our Goodman furnace just started making a a very loud grinding noise when the furnace turns on. Also the temperature in the house keeps dropping so we have to keep adjusting teh thermostat. Any advice on...


If it makes the noise before the blower comes on it would be the exhaust fan. If it makes the noise when the blower comes on then I would say either the blower motor or bearings to the fan.

I have a Goodman GMPN furnace and the motor that runs the twin blowers has quit. How do I take it out and replace it?


If you mean the blower wheel, I wonder how you diagnosed this problem so you were 100% sure the motor is bad. I recommend to make sure of the diagnosis before spending to buy parts.

The blower wheel is shaped like a twin blade. But it's only one wheel.

However, to answer the question; Step one is turn the power off.
Then; Find the blower housing in the lower compartment on an upflow configuration.
  • Remove 2 screws on the blower housing, on the upper inside of the blower compartment to slide the blower housing out.
  • Disconnect blower motor wiring at the harness and at the control board if connected. You can cut them if you have exact replacement motor and wire nuts.
  • Slide the housing out, turning it on the side that exposes the motor.
  • Remove the 3 mounting screws holding the motor to the housing.
  • Loosen the lock nut holding the fan blade (wheel) to motor shaft.
  • Slide motor and shaft out and away from the fan blade, as they are connected together and cannot be separated. Use penetrating oil SPARINGLY.
Installation is the reverse of the removal instructions.

IMPORTANT. Make sure to leave equal space between both sides of fan blade and housing when re-installing the wheel.

Luck to you. Let me know how that turns out.

Intake vent needed?


The blower motor is only going to pull a certain amount of CFM for circulation air. There is some restriction of air flow that is created when the return air system is ducted causing the air flow to "slow down" a bit. The air going into the furnace firebox is probably moving at a faster rate than if the return air was ducted. It will work and you will get the same amount of heat (energy) released but the faster moving air will make it feel cooler. Also the unit might be undersized(BTU output) for the size of the cabin and amount of airflow the blower is creating. Adding a extra filter(double) might slow down the air flow a bit to create more warmth(feel) coming from the registers. Also if the furnace and air intake is pulling air from outside(garage,closet, or under house) then the colder air from outside going into the system will decrease the heat from the furnace. It is better to have a closed system (return air inside cabin). You might want to try adding a extra filter to slow the air flow down some or use some sheetmetal and square it from the intake to try and concentrate the incoming air a little better and see if that improves the warmth coming from the furnace.

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'm considering installing a Goodman LP Gas Furnace:sizing? Ops?


Gerge, if you go to website www.energycodes.gov
you can do a heat load calc yourself. Basically, you figure out the sizes of walls, total area of glass. total doors to outside, ceiling area and types of building materials used. It is pretty easy and then you will know for sure. The contractor should be suppling you with one but if not use this, it is free!
