Re: heating problems

It sounds like the unit is going into a defrost cycle, which is normal for heat pumps and means all is working ok when it gets around 35 or colder they start to do this more often when the red light goes back off , the outdoor fan should come back on. You may also notice steam (may look like smoke) coming from outdoor unit. Is that what happens??

MY outside unit will not kick on now I just had it filled and seem to not want to kick on so I'm thinking it a short or the new t-stat that was just replace over the winter heat side works fine

Turn breaker off. Wire nut the red, green and yellow. Turn breaker on. Check outside. If unit is running either your tstat is not setup properly or it is bad

The unit will come on in house but fan is not on outside you can hear it clicking like its trying to and blowing warm air

I have a 4 year old intertherm AC /Heat pump...all works ok - but sometimes in summer or winter - when the inside unit cuts off - the unit outside still runs and whines and sorta sounds like a grinding in...

Has it always made that noise? If so then I would think that after 4 years and no problems that it is nothing to worry about. If it is something new then turn it off and call a service tech to look at it. I am leaning toward the service tech.

Fan not working on outside AC unit

The buzzing noise is probably the fan motor. Is the compressor running? First make sure that there are no tripped breakers. After that kill the power and check the capacitor with a multimeter. If that checks good then check the fan motor windings with the multimeter. Let me know if you have any questions.

Heat pump 5 ton package unit

You have two of your t-stat wires that are shorted out. Disconnect the wires at both the unit and t-stat. Take two wires at a time and ohm them out. If you have continuity those are the shorted wires. Substitute them for two different colored wires if you have two wires that are currently unused. If not you will need to pull new wire. Please answer back to say if this works or not.

Sounds like you have a freon leak or your compressor has stopped working. You will probably need a service tech. If it is out of freon, don't let them just add more freon, make them find and repair the leak first. Good Luck.

Ruud heat pump outside fan

You may be right in looking at the motor. It uses a different speed on heat than cool. The heat cycle uses low speed, usually red. Some manufactures use blue (medium). Cool uses black, high speed. If you are confident, switch the low speed wire with the high speed and see if this changes anything. If the fan motor isn't the problem, check the other setting (cool) if the overload trips, you may need to look into a new capacitor or compressor, if so, you can install a hard start kit. these are start boosters, and are inexpensice, sometimes they will give another year out of the comp. but I've put them on and they have lasted 5 years.
