I have a weather king ac unit 2 ton. The model # says SFC924C-1B on the back. Today I was sitting outside and I heard a relay clicking sound every few minutes from the unit. The ac unit was cooling my house fine, I don't smell any burning or whatnot. It just kept making this clicking sound... Is this normal or is there some sort of problem here?

How old is this ac unit? I can't find ANY info on it online...

Thanks for any help you can give folks!

Did the fan or anything stop? How often was it clicking?

No it seems to be working as normal. It only clicks every 2 to 3 minutes. Sometimes it only clicks a few times in a 10 min run. It sounds like its coming from the box on the back wall of the uniton the inside of the condenser where the thermostat and electrical wire goes into the unit.
