Smell of burnt rubber inside garage. Probably the AC Unit?

It could be a number of things. The blower motor could be going bad. Sometimes the windings in the motor get hot and smell like that. I would be really cautious of a burnt rubber smell coming from the unit. It might be smart just to shut it off until the tech arrives so that it doesn't cause any further damage or start a fire.

Your unit may be overheating. Are you changing the filter regularly? I sell real estate and many times this routine maintenance is overlooked which results in a shortened life-span for your AC. Don't be afraid to remove the door and look to see if there is a wire that is shorting out. If y ou are a complete novice, call a technician today as this may be a fire hazard.

you realize this time of three hundred and sixty 5 days alot of individuals do burn their leaves and rubbish and stuff. Im no longer attempting to be a smartass yet you will possibly desire to be smelling that. I even have had sessions like that to I scent burning rubber or hearth with out actual looking clarification nonetheless. Take care i'm hoping you stumble on out what that's. i might fairly decide to appreciate.

Check the Fan Motor it could be overheating due to no lubrication. Insulation of the armature or field coil could have been toasted, since the insulation is shellac it would smell similar to a burn rubber if subjected to extreme heat like overheating.

for your sake i hope the rubber you small is not the wire insulation. for starters air out the garage and then shut the a/c off unplug it see if the problem is still there.

question to you......how do you enter the garage? a door? or open it with a garage opener? if its the latter I suspect a belt on your garage door opener is wearing.
