If it is just the condenser fan that means you have a fan relay that has welded shut.Turn power off to your unit and trace the wires from your condenser fan back into the control panel at the unit.You'll have 3 wires going to it.2 go to the run capacitor and one goes to the fan relay.The one that goes to the fan relay is the part that needs to be replaced.If you have no fan relay and it goes to the main contractor, half of your main contractor is welded shut and will need to be replaced.
Hummm. A bit difficult to solve this problem. Seems like the condenser outside is not working, I mean the fan of the condenser. Looks like you have a wall A/C and a wall A/C always have condensers outside the house and near the A/C. Have you checked if the fan is spinning? I don't think the compressor is at fault but check it anyway. You should be able to hear the compressor running either in the wall unit or in the outside condenser housing. The only heat you should feel is from the condenser itself. If you blows warm air, that means the fan is working, if not that means the fan is not working. But don't be confused with the fan not working because in winter time sometimes the fan is not working and some times it does. As I said, it's a difficult problem to solve but at least start with checking the situation with the fan in the condenser.
These Ptac units are advance system that are designed with variable speed motors that modulate in order to save energy, This is normal operation, because starting a motor at a lower speed rather than the conventional high speed will save energy, which translates to saving you money. As the load increases (heat) on the condenser coil, the fan will ramp up accordingly.
Hello, most window units evaporate the condensate by having the fan blad sling the water on the condenser. Because the condenser is warm/hot it will evaporate. You shou.d be hearing a sloshing sound after the unit has benn running for a while, this indicates that the fan blade is picking up the water from the bottum of the ac.
regarding on switch mode theres a common line between heating and cooling although fan is always connect on them.,also with the thermostat,the sequence on this when you switch to cooling and your connection is on heater,the contactor will shift to compressor source,so if there is no cooling, the contactor supplying the compressor is not functioning when you switch on cool mode.try to tighten screw on compressor relay maybe only loose.on control panel,or check continuity of compressor if the compressor still good,check also the freon charge using clamp ammeter,this should be done by ac technician.have a nice day
rate me up,thank's
if the fins feel cold then you should be collecting condensate. so try this: remove the outer shell to access the fins. with a garden hose, spray the fins off thoroughly. you may see a lot of dust and line that was clogging the air flow.
