First pull the quick disconnect (power source). If you have a multimeter with capacitor check (uf) capabilities, look at the side of the capacitor and see what the uf rating is, (should be somthing like 3.5uf or 5.0uf or7.5uf) then stick a screwdriver between both contacts where the wires are pluged into the top of the capacitor and touch both contacts at the same time to discharge any stored electric power, then remove all the wires from the top of the capactor, switch on the multimeter and set it to the uf setting, now place one lead on one side and one on the other, if your capacitor is say a 7.5uf and the reading is 9.0uf or 6.0uf it's bad replace
the capacitor. check both of your capacitors the same way, oh mark your capacitor and the wires so you can put them back together rite. If you don't have a multimeter with capasatence checking capability take them to an appliance shop and let them do it for you.

A/C MOTOR STOPS RUNING AFTER 10 MI I REPLACED WITH NEW FAN MOTOR AND CAP


Run the motor as long as it will run, carefully feel the motor and see if the case is extremely hot, if so, the internal safety is tripping to protect the motor, after a cool-down period the safety should reset. If this is the case, verify proper Horsepower rating, rotation of the motor, proper amp draw during operation and proper capacitor connection and size. Hope this helps.

My air conditioner fan motor runs in reverse thus, none or very little air is coming out


The fan motor can be wired correctly for up flow and still run backwards for downward flow or reverse when you put the wrong value capacitor or connect a hard start capacitor to an already bad start dual cap. Case in point: I come across a condenser where the fan motor is running (in the right direction, up) but the compressor is not. I put a hard start cap on the dual cap. The compressor comes on but now the fan motor runs reverse. No other wiring was changed. The hard start cap connected to the defective compressor start cap shifted the current, voltage phase 180 degrees to make the fan motor run backwards. I removed the hard start cap, removed the defective dual cap and replaced the dual cap with a known good one and everything worked correctly.

Condenser fan running backwards on heat pump


I am having the same problem, sometimes it runs in the wrong direction, blowing the air down. Sometimes something gets tripped and I need to turn the thermostat to off and wait a bit then restart it. If I am lucky it will run int the correct direction and also will warm the house. Sometimes it send nothing but cold air to the house's forced air.

Have to manually help fan to start rotating


Nope, run capiacitor, fan motors don't use a start cap only compressors. However, the problem is most likely bad bearings in the motor and the motor needs to be replaced. If the run cap were bad you would have high amp draw when the motor is running and would trip out on overload or burn the windings.

Outside Fan Problems


TRY CHANGING THE CAP FIRST BUT MOST UNITS ONLY USE THE CAP TO START THE MOTOR NOT TO KEEP IT RUNNING SO IT SOUNDS LIKE YOU HAVE A BAD CAP AND THATS WHY IT DOESNT START HOWEVER IF IT STOPS RUNNING WITHOUT THE THERMOSTAT TELLING IT TO (OR IN THE MIDDLE OF A CYCLE) THEN YOUR RUN WINDING IN YOUR MOTOR IS GOING BAD YOU CAN REPLACE THIS MOTOR PRETTY EASY AND IF YOU USE AN AFTER MARKET INSTEAD OF AN OEM MOTOR YOU CAN SAVE YOURSELF ALOT OF MONEY. PS BE CAREFULL WHEN CHANGING YOUR CAP BECAUSE EVEN WITH THE POWER OFF IT CAN SHOCK YOU.AFTER SHUTTING THE POWER OFF USE AN INSULATED SCREWDRIVER AND TOUCH IT ACROSS THE POLES AT THE TOP OF THE CAP TO GROUND IT AND REMOVE POTENTIAL ENERGY.

PORTABLE A/C


I WOULD TRY TO INSTALL A HARD START KIT ON THE CAP IF YOU CAN SPIN IT AND IT RUNS LIKE YOU SAID WHEN YOU FORCE IT TO RUN. IT SOUNDS LIKE THE START CAP IS NOT STRONG ENOUGH TO START THE MOTOR WHEN IT HAS BEN RUNNING. A HARD START HAS TWO WIRES AND IS EASY TO INSTALL
