I want to personally thank you for the video. It saved me at least $500 according to one of my HVAC friends. It took me 5 minutes to remove the capacitor and 3 minutes to install the new one. Everything working beautifully.

@joanncard8836 Жыл бұрын

This is one of the best videos. Even if I cannot fix it myself, I now know what a service technician should be telling me.

Thanks! This vid helped me ensure that the sound I was hearing was what I thought it was. The capacitor cost $3.70. I had a friend pick it up on the way over. They were happy to help, and refused to accept my payment for the part, as I didn't charge them for lunch. Likely saved me $300-500 for a service call to get it fixed, and was solved before I had my morning coffee, rather than waiting a couple days in the heat for the repair.

Thanks for the video .Especially the discharge reminder. Mine quit when we are having 100 degree heat and its in the attic so its 120F up there and I'm old. Its a short term fix but I went up and banged by hand on the cover . It solved the problem but the system is 35 years old so at least a new capacitor is in order. Local HVAC place have them in stock for $10. Other tell tale sign is "cooling on" flashing on Honeywell thermostat just below actual temp display. Will flash when blower fan not acting on call for air.

Not replacing batteries in thermostat cost me $500. Air handler stopped blowing completely but was humming and froze the inside and outside unit. It's under warranty and ac tech replaced blower motor. $310 for labor $97 for service fee and $90 for refrigerant. 2 days later it wasn't working. On a hunch I replaced thermostat batteries. Instantly the system was working fine. No problems since. I hope this helps somebody out there.

I started to dig through what could have been going wrong, the hum was going still going on- the circuit board... I don't have to replace the whole thing, or just which part (haven't found it yet... I still have to check it with my meter) Sorry this is so long ago of a question, but I'm completely lost on this.
