You want to shut power off to outdoor unit?
Why do you want to shut power off can I ask?
I think you may have been working with someone else. Can you restate the original issue and I'll try to help you here. I have no information other than the model number. What's the unit doing? Not doing?
Is it cooling the house, bringing it down to setpoint?
No, you misunderstood. I was asking you if you wanted to shut power off to outdoor unit?
In your original question, all you said was "shut power off to outdoor unit". So I assumed you wanted to do that. I had no description of the problem, now I do: you say it runs constantly.
If the unit runs constantly, this can be a bad thermostat, a stuck contactor, or low on charge. Is it cooling the house OK?
So when you say it "runs constantly" is it just the indoor blower that runs constantly, or both indoor fan and outside unit?
So only indoor fan runs constantly?
With your thermostat set at 63 deg and 83 in the house, the unit has probably lost charge. Not unusual with a 24 year old unit.
Unless it's a small leak, probably not worth repairing on this old a unit. To make matters worse, you may have a defective thermostat.
There is a part inside the outdoor unit called a contactor that might be sticking to compound things.
Yes, as I said if leak is not too bad.
It is a part that needs replacement. May look similar to this.
Not if it was really low, no, you wouldn't see signs of icing or frost
Yes, good luck! Thanks for using Just Answer and please don't forget to rate my service as that's how experts get paid (thanks in advance for any bonus left). Otherwise experts work at their own time and expense. Feel free to post back with any additional questions.
