Not an easy task! Take many pictures as well as draw out and mark which wire went where. You will have to remove everything from inside the cabinet to get to the heat exchanger. It may be easier to replace the furnace. If you are paying a professional to do the exchange, figure three hours if they have done it before, if not figure 5 to 6.

If you are getting flame distortion when the blower comes on it usually means a cracked heat exchanger which can lead to carbon monoxide, get your furnace checked by a qualified tech..

How to change fan speed on a goodman gmp 100-3 furnace


Usually you can find the control board on the lower part of the furnace. Turn the power off and remove the
doors. This board is usually located directly in front of the blower motor.

On the control board locate the terminals marked heat/cool/park and Park Lets say the Heat Terminal
has a red wire attached to it and you want a higher
speed.

Red is uasually low speed, remover the red wire from
heat terminal and exchange it with a wire attached to
a terminal lab eled park. Black is usually high spped

Goodman furnace\ blower comes on,unasked


Sounds like the fan switch on the furnace is set to low. Turn power off to furnace, take door off of furnace look for a fan switch, it may be a fan - limit together. The limit settings should be approximately 160° to 200°, and the fan settings should be about 100° to 140° set it to 120° it it's already set there then you probably need to replace it.

Support on changing out the heat exchanger on gmnt 080


1st, take a picture of where each wire goes to. Look in the owners manual for an exploded view of how it goes together. The heat exchanger most likely comes out from the front of the furnace. You will have to remove and reinstall every componant inside the furnace to get it out. Suggestion, replace the whole furnace. It will be cheaper.
