It is three screws and two electrical connections.. EASY
Replace blower motor it's burned up.
If the motor has oil ports you can put in a few drops of oil. If the motor has sealed bearings you will need to replace it.To fix a squeaky furnace, you need to add oil to the motor bearings. In some cases it could also be due to the fan, which would then need to be replaced.
It is fairly difficult to do on a lift, very difficult to do on the ground.
A 120 volt motor is the inducer motor. It works the furnace.
To add the sae 10 non detergent oil to your furnace blower motor you will have to open the motor section.
What size motor? What accessories do you have? BClear.
it is on the firewall and difficult but not impossible to get to and replace.
Replace it. This is probably a sign of badly worn bearings that make it difficult for the motor to spin.
Very difficult. I would leave it to a glass shop.
Call an electrician; something in the furnace, possibly an electric motor, is using too much electricity.
