Is the compressor running in the outside unit? If it is then check the capacitor for the fan and replace if necessary. If it's good then check the fan motor. If the compressor is not running also, check the circuit breakers or fuses and the contactor in the outside unit. Let me know what you find or if this helps, please rate it.

    Irrelevant...the fan runs...208-230 is present.

    To correct.....on a RUUD, RHEEM or similar unit, the red wire tends to corrode and burn off on the compressor terminal. I'd start THERE.

Hello, if the airflow seems good and the unit is clean it is possible that the unit has a low refrigerant charge due to a leak, if you have a thermometer measure the return air and the supply air, tjen find the differance between the two, if it is below 15 then the unit is undercharged and will neec to be recharged.

You can remove the face from the thermostat and see if that stops it. If it does the problem is in your thermostat. If it doesn't then a contactor or relay is stuck. Let me know what you find and I will offer more suggestions.

The inside RUUD AC unit has ice and no cold air is blown


it is likely low on coolant or as some say "freon" that or the indoor fan motor has not run properly. let it thaw completely by shutting it off and just turning on your fan switch from auto to the on positon. if you begin to feel air flow eventually you need coolant added b/c you probably have a leak from the system being old

Ac fan on, blowing air, but not cold


Check outside unit if unit and compressor are running feel the large line to see if it is cold. If compressor is running and line is not cold possible charge problems. You may have a capacitor problem outside. they go out quite often. You can change this yourself, Open up outside unit and the cap is the silver bullet with terminals out the top. Bad cap can cause compressor to not operate and also the fan. You need to clean the coil inside or at leat check the coil to see if it is clean. You can clean theis with a toilet brush do not go against the coil bit brush with the fins. You may need to call a service tech but try these options first. russ

COMPRESSER IS VERY HOT, FAN OUTSIDE BLOWING COLD AIR OUT NOT HOT


Most likely the unit is low on refrigerant. You could also have a restriction in the system. You need to put gauges on the unit.

Not blowing cool air on my Ruud, 18 years old, outside unit.


If you have ice on the Line you are iced up. If coil is iced no air can get thru. Now First. Turn of ac and turn fan to on posotion. That will thaw unit. Let it run 45 minutes. That should do it. If the fan is not running you amy have a bad fan relay. One of the reason iced up unit is dirty evap, coil inside. Try to thaw it out first. You can clean the coil with a stool brush. Does not damage the coils. Good luck
