Condensor fan runs after compressor shuts off

I replaced the condensor fan and now the fan will keep running after the compressor shuts off. I could use a schematic showing the correct way to wire the condensor fan.

If new motor is 4 wire verses 3 wire use seperate capacitor between brown wires and don't use terminal on 3 pole cap. If this motor has a white strip on one brown wire you can wire it the old way using only 1 brown wire and tape off the other. Can't remeber this morning which brow wire to use . I need to leave. Goole replacemotor with 2 brown wires for more info or call where you bought it. Sorry got to run.

How to troubleshoot thermostat wiring?


I'm not sure if the thermostat is wired correctly. First, the thermostat is wired directly to the outdoor unit (compressor/condenser unit). It is NOT directly connected to the indoor unit. It connects to a low voltage control panel in the outdoor unit that sends a signal to your indoor fan/evaporator. This wire is called the fan relay switch and physically runs between the low voltage controls of the indoor and outdoor units. If the fan relay is bad it's possible that the unit runs continuously. To prevent destroying your outdoor unit there is a safety feature that prevents the indoor fan from shutting down while the outdoor unit is running. If the indoor fan did shut down while the outdoor unit was running than you would slug your compressor. That is, your compressor normally sees refrigerant gas but is instead seeing refrigerant liquid. That would not be good since this scenario would destroy your compressor. It sounds like a faulty fan relay. The actual contactor portion of the relay is in the outdoor unit.

COMPRESSOR RUNS A LOT


Your model has a mechanical thermostat inside the control panel. I believe you have something else going on like a bad fan, start relay, capacitor. Something is causing the compressor to struggle to keep up and in turn causing the compressor to short cycle. If the thermostat has no control over run time then something like I explained is causing the problem. Here is a parts manual=> ED5VHEXVB04 Contact me if you would like my help, Thanks Sea Breeze

My compressor will not start, the interior house fan runs


you might check the contactor it should have 240 vac. this is what starts your compressor and your condensor fan motor. You have a problem with the outside unit. It is electrical in nature the contactor is a big black rectangle box. It should show it on the schematic on the unit.

Aircon split unit in summer start up ,condensor fan and compressor are running ,after +- 3minutes condensor fan stops and compressor keep on running.What can cause this problem?


Check all your wires and connections of your condensor fan. If there are damaged or overheated wires or connections, correct them. Make sure connections are tight.
Check for "play" in the motor shaft. Hold the tip of the shaft and try moving it side-to-side in all directions. If there is any "play", the bearings are bad and the motor needs to be replaced. Up-and-down play is normal......do not confuse that with side-to-side play.
When the motor first locks up, while running, try turning by hand (BE CAREFUL). If the motor is tight, the bearings are bad. You might be able to buy a little time by oiling the bearings, but once they lock up, they generally will remain troublesome and need replaced.
Also make sure the condensor coil is clean.....wash it off with a hose.
I hope you find this information to be very helpful to you as a solid jumping off point moving foward. :-)

The AC in my 2004 Honda Accord only blows cool air when I am driving at higher speeds. When I drive slow or am stopped, it's warm hair coming out. My mechanic said the compressor isn't working properly...


it is a premature failure, That does indicate a bad/failiing compressor, or low oil charge, to low freon. If you trust the mechanic then go witht he compressor replacement and condensor. Unfortunately most oarts stores/shops require the condesor to be replaced for warranty purposes on compressor replacements.

When unit starts the condensor fan only comes, not compressor


You need a new fan motor and the correct capacitors for your sydtem I think they are 35 or 45 5 cap. Try a hard start kit on compressor. Are you sure you have the cap wired correctly?Russ

The condenser fan might be going out. It'll start when cool but shuts off as soon as it starts to warm up.
