Question about Ruud Central System Air Conditioner

1 Answer

2.5 RUUD AC not working, power must be getting to the unit.

I have a 2.5 ton unit (Ruud) and the house is warm and the fan on the the unit (outside) is still running. Hard part is I am out of town, wife and family home in the hot house so it's hard to get information. Tried setting the thermostat low, switching of fan, curcuit braker and so forth. No luck.
Where should I guy start?

Have them turn the outdoor unit off and wait a few minutes. When they turn it back on they should here
the fan and the compressor come on. They are to different sounds.

If they think that they have both come on, tell them to check the black insulated suction line. it should at least cold to the touch. If not it could be a freon issue.

If the line does get cold, have them checkthe filter in the house. If that is ok tell them to turn the power off
to the outside unit. Take a garden hose and wash
the outside coils on the outdoor unit,be carefull not to
smash the fins. Wash them at an angle from top to bottom.

Ruud Achiever 10 heat pump - outside fan won't shut off


Definately get this checked out. Some thing has shorted just enough to let voltage "Feed back" and keep the fan running. Could be capacitor, wires rubbed through each other, etc. A reset is a safety that is used when there is an overcurrent or over pressure situation. No reset set for this situation.
There is always an outside chance that if you touch the unit while standing on wet ground, you may get shocked. I firmly believe that something is allowing power to the fan in a feedback condition so don't let this go as it may cause damage to other parts.

Good Luck and let me know how you make out on this.

Ruud heat pump question


Does the air handler take a minute or two to start, this would be normal so that it doesn't blow cool air into the house before the unit is warmed up. If not could be the fan relay is weak and needs replacing. As far as the outside unit it sounds like you need to check the refrigerant. In cooling they are 70/150 psi. This should be checked in cooling mode, once you turn it to heating mode the pressures switch bring heat inside the house instead of out. I hope this helps.

It sounds like your condenser fan motor may be locked up or the capacitor that helps give the condenser fan motor a kick to get it started may be defective. Try turning your system on and using a long screwdriver try to push the fan blade on the condenser fan motor to see if it will run normally if you give it the starting boost it needs.If it does run at full speed and doesn't over heat or start and then slow down then you probably only need to replace a simple 10-12$ capacitor. If it barely turns, makes an odd humming sound or overheats etc. then you will have to replace the condenser fan motor. This is assuming that the outdoor condenser has the 220v supplied and the 24v supplied to the compressor relay, that the compressor relay is engaged and suppling 220v to the condenser fan motor.
