Auto/On set to ON. Fan runs.


Sounds like the thermostat, the way to verify is to unplug indoor unit, remove thermostat, take pic of wiring with phone or label the wires as to the terminals. Carefully twist the yellow,(Y) Red (R) and the green (G) together. Plug the furnace back in, if the unit operates normally, replace the thermostat. I am basing this on the fact that the blower speed is changing. This could also be an anomaly within the circuit board in the furnace section, not likely though as the outside unit (condenser) is not controlled n by the indoor board unless this is a heat pump. hope this helps.

My goodman cental air system is having problems. First, the blower inside (furnace) keeps running for hrs after the outside condensor shuts down. Now, the condenser blower motor wont operate at full speed....


the cause of your indoor fan running all the time or for long time after your heat pump has stopped heating is the fan delay relay. It has welded its internal contacts together. If you take off the side below the control panel, the fan delay relay is normally mounted on the header where the fan discharges. Good news, the fan delay relay are fairly inexpensive and easily to change.

As far as the condensing fan motor not running at full speed, when it was changed, did the technician install the correct fan motor. Most condensing fan motors are either 875 rpm or 1175 rpm. They are exactly the same size and if the technician did not look closely he could have installed the wrong rpm motor. There is another possibility, he may have used the wrong capacitor. I have seen the condensing fan actually operate backwards at a lower than normal rpm. The fan if properly installed will discharge air upwards.

Hi,
It is just coincidental that the fan motor died now...

Outside condenser fan won't run. I have pwr going to the contactor. The fan spins freely by hand. When I turn it to cool I get high and low lights illuminated on the circuit board. What do these mean??


You did not mention if the compressor ran when you depressed the contactor. The condenser fan is tied into the compressor wiring so if the compressor runs, so does the condenser fan. That is unless you have a winter kit in it which allows the condenser fan only to operate once it hits a certain temp. If you are getting error codes, I would say you have low refrigerant.

Lennox central air for home not kicking on. Fan on the outside not spinning but motor is making a humming noise. No cold air coming in home. We have circuit breakers they are turn to the on position. ...


Is the indoor fan working? The problem with the outdoor fan sounds like it could be your capacitor. Turn off the power to the outdoor unit and make sure the fan turns freely using a screwdriver or something that will reach the blades. If it turns freely then it is probably the capacitor. Let me know what you find.

Hi!!

Replace motor fan and capacitor, it is a very simple task. Turn breaker OFF. Then all you have to do is remove about four screws from the top grill, about four more that fasten the motor fan assembly, unplugg electrical connectors and label them and install the new one and switch fan blades.

No special knowledge is required to perform this job. Cost: about $140 +-.

On the other hand, you call a HVAC technician, they supply the motor and capacitor, otherwise they won't give you warranty. Cost $300+. Look on the Yellow Pages for one in your neighborhood.

Good Luck!! Rate this post!!

Indoor air flow slow comiing


Have you checked your air filter(s)? Is the fan running? A weak capacitor will make a fan run slower sometimes. Also try turning the fan by hand while its off and make sure it spins freely. If its hard to turn you probably need a new fan motor.

We have a dayton gas furnace model #3E463A. thought the control box was gone. got new one we furnace starts up the power goes on, fan starts no green pulsing light on control no ignition


When your furnace starts...the Ventor motor(exhaust fan) starts up....within a short time (seconds) the Pressure switch closes proving that the Fan is indeed running and the vent is not blocked...if this doesnt happen the furnace will not poweer the ignitor or fire at all....Check the vent pipe outside and look for obstructions or dirt on the screen inside the pipe...the condensate from the fuirnace may not be draining at all...due to plugged condensate drain lines...find this tube coming out of the furnace front...bottom of upper compartment usually , and pull it off the tap....if water starts coming out then your drain is plugged downstream of the furnace.

Well when i turn on a/c condensingcome on and


is your indoor fan motor noisy? Right after it shuts off feel if it is extremely warm (carefull, may burn you if you leave your hand on too long). If it excessively hot, the motor is tripping on overloads located in the motor itself, probably the bearings are dragging. Check to see if it spins freely when spun by hand. If not replace motor. Make sure power is off while putting your hands in or around the fan

Air compressor kicks on but fan doesnt and vice versa


I assume you mean the condenser fan motor ? Try to manually spin it. If it is hard to turn, change the motor. If it spins freely, change the capacitor.
