outside condesor keeps shutting off


the fan would run for about an hour then would stop it did this for about 4 days and now it wont turn on out there and wont come back on at all. we have somebody comeing out this week i just wanted to see if anyone had any ideas we thought it may have been the fan motor but were thinking its the reset switch at the bottom of the lennox.. anyway thanks for reading

that is most likely a high pressure reset for the compressor...is the motor body hot to the touch on the motor body...if not could be just the capacitor easy change out Grainger supply...??? is the compressor running without the condenser fan?

Did you ever determine if your fan run capacitor was the problem? If the fan is not working properly to move air the head pressure will rise and trip the high pressure switch. Lack of air flow due to a dirty condenser coil can make the high pressure switch trip also. Of course, too much refrigerant can make the high-limit trip also. It could also be the fan motor going bad. If you haven't done so I would wash the condenser coil to see if that helps.

in the off position free spin the condenser blade CW CCW if you here grinding(like brakes) at all the bearings are rusted and tight especially if it stops as if breaking short....so go for a new cap and motor all at Grainger.trick spray some WD-40 on the blade nut holding screw need to save the blade.....might see a change in that spin test if the spray goes down the shaft into that tight bearing..eye ball that contactor if arcked/black carboned up might change that also...230V/24V coil/30A.that HP is on the Freon side with a change out its on the 24V control side that knocks out the contactor...that is why the compressor and fan go off both come off the one contactor...sounds like the motor get back...and get a new EXACT capacitor change out...if the HP is knocking the condenser down grab the this raw copper line out of the condenser when it starts if it hot to the touch the condenser is dirty...
