Question about Heating & Cooling

1 Answer

I just installed a new blower motor for a GMP075. I put all of the wires back where they belong. However, I cannot start the fan or anything. There's power through the door switch and transformers, but no LED is lit up.

Blower Motor will not work when resister is installed.


Check the contact connection on the connector, many times these overheat and melt the surrounding plastic. You may need to replace the connector wire harness.

Gmp075-3 which is the main limit switch ?


The limit switch is a credit card size shaped switch right behind the burners which has two wires attached to it. This switch will trip if the Furnace is overheating, this can be causes by a weak blower motor, dirty air filter, dirty blower wheel....anything that restricts airflow.

My fan for the A/C will not come on unless I hit a big bump in the road and then it runs fine? Is there a short?


This is caused by a defective blower fan motor, replace it.
Removing the Blower Motor
  • 4Remove all four of the screws from the glove box with your Philips screwdriver and set them aside.
  • 5Slowly remove the glove box from the dashboard. Make sure that no wires get caught or stuck. Place the glove box and its screws to the side of your work area so that they're out of the way.
  • 6Locate the blower motor under the dashboard. It will be shaped like a small circle, and is about as big as a saucer used to hold a teacup.
  • 7Unplug the wiring harness from the blower motor. Use the painter's tape to mark the wire, then temporarily tuck it out of the way under the dashboard.
  • 8Remove the three screws that hold the blower motor in place.
  • 9Carefully remove the old blower motor and place it to the side of your work area.
Installing the Blower Motor
  • 10Inspect the new blower motor to make sure that it isn't damaged. Check both blower motors side by side to also make sure that they are identical parts. Place the new blower motor back into the same exact position as the old one. Make sure that all three of the screw holes line up correctly with the new blower motor's screw holes.
  • 11Secure the blower motor by returning all three screws using your Philips screwdriver. Be careful not to strip the screws. One quarter turn past hand-tight will be enough to secure the blower motor.
  • 12Remove the painter's tape from the wiring harness and plug it back into the new blower motor.
  • 13Carefully slide the glove box back into position while making sure no other wires are caught or tangled, and resecure it with its screws.
  • 14Remove the black tape from the battery cable's metal terminal and reattach the cable to the car battery. Start your car and test out the new blower motor on all of its air settings to make sure it works properly.

I have a 1992 Honda Accord. When you shut off the car the blower motor stays on and the lights on the heater panel.


Make sure your fan is wired correctly, if the fan is wired correclty which it may but could be crossed and spinning backward and sending power through ground wire causing a power up of the inside light and blower, if the wiring is good then replace the cooling fan relay, that must be shorting and back feeding power to heater control.

Goodman furnace GMP075-3 The thermostat was in the off position over night and sometime during the night, the induced blower and blower motor came on. The trouble light on board blinks 5 times. I checked...


Need your model # to check the codes but, this coming back on after turning the t-stat off is rare. You may have been in a lockout and the furnace re-started. Some furnaces try to start three times , then lock out. Time out, then re-start. The codes should be on your furnace blower door. Write back with this info and i could help.

Outside ac unit operates but no blower. Fan "on" does not operate from thermostat. However "heat" works fine furnace and blower. ???


Go to furnace and shut off power, remove blower door compartment. Inside you will find a control board where thermostat wires are connected. Should look something like this:

R-Red Wire= Power
G-Green Wire= Fan
W-White Wire=Heat
Y=Yellow or Blue Wire=Cooling.

It sounds like you have a bad motor speed. So try this:

With Power Still Off, on the same control board there is a terminal usually marked Cool and Heat. There should also be a couple of terminals that are named park. The wires hooked to these are the fan wires..

Exchange the Heat and Cool wires on the terminal board. Put everything back together and try cooling again, if the fan comes on
then you have a burnt out motor speed. Go back to furnace and change
the heat and cool wires around, next if Cooling had the black wire hooked to it, put yellow or blue on Cooling and black to park.


Note: The reason why you put the blower door back on is because it
has a door switch that if not properly seated, you wont be able to power
up anything

Want to know how to install the blower motor in my 1997 Oldsmobile LSS


It's located in the middle of the firewall and has 5or6 7mm screws you'll need to remove.There's a 10mm nut holding on the squirrel fan,Hold on to the fan to remove.There's a stop washer under the fan,you'll need it for the new blower motor.There's a flat spot on the shaft to keep the fan from spinning,make sure you not only line it up and put the fan on the right way.If you put it on backwards it will stick out farther and won't go back in all the way.When installed it will be very close to the blower housing ,if there's a gap take it off and flip it over.If the fan hits the housing the stop washer must of fallen of the shaft or you forgot to put it on.Put the nut to hold the fan on,don't strip it out,it only needs to be tight.Plug the wires back in and test before you install,don't get bit by the fan!Install in the firewall and only tighten the screws, they strip out easily!That should do it!

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.
