Hi I have a Goodman Furnace GMP 100-5 with an AC connected to it. How should the wireing be connected to the furnace. It does not work when we turn on the heat. Currently the furnace has a brown wire coming out with 5 wires which is connected to the brown wire from the AC unit. The furnace also has a yellow, white, brown, and green wire hanging out. The thermostate brown wire has 5 wires and the yellow wire is connected to the red wire on the AC wiring and the red wire is connected to the brown furnace red, the green wire is connected to the green wire coming out of the furnace. The other 2 wires white and blue are not connected to anthing.What is the proper way this should be wired?

I don't know where you are located, but there is a Goodman distributor in Sacramento, CA. Also in Ontario CA. They are a distributor so they may be able to help you or tell where to find someone who will help. Goodman is also known as GMC or Janitrol.

I have a goodman electric furnace. Model no AR32-1, where can I get a manual. My furnace is making a grinding/squeak noise. Is it okay to run it until it's fixed?

I'm not sure you have a true Electric Furnace or a Heat Pump, since both are electric.

In any event, Goodman has Owners manuals that you can download in a pdf format. Just look for your model #.

How do you change the filter on model# GMP075-3?

When looking at the front of the furnace, toward the top, turn the two black tabs so they are vertical, then pull it forward. This will take off the top panel. Now pull the bottom panel up, then toward you. You can now see and change the filter.

Is there a diagnostic chart either on the reverse side of the blower door or in your owners manual. It may help you to narrow down what is going wrong.

Operate the furnace with the access door off of the furnace and the blower door switch taped on. Watch the furnace and document what happens. Note if the flame starts but goes out in a few seconds and let me know what you experienced.
