I have a problem and I'm hoping it's an easy enough solution... My wall A/C unit (which I would wager is rather old) had an issue with the low fan setting. On low, the motor will eventually slow down and it sounds like it's trying to work but it's not doing much. On high, everything works just fine. Usually on low it'll work for a while, then start to slow down and eventually stop... Although today it wouldn't work right off the bat. Again it sounds like it's trying but it's either not moving or moving very slow (no air is being moved). It's a 240v unit, if it matters.
Any low hanging fruit to check in regards to this? I'm not going to spend too much time on it as it's likely 30+ years old, but if there is an easy fix I'll try that.
