ac tripping breaker

Check for loose wires. Check the capacitor for any signs of failing such as swollen, weeping , etc. Also check to see if your AC has a start capacitor....if it doesnt you should add one. If all looks good up there it could also be a faulty compressor. The fact that your breaker is tripping could be a fault in the AC or it could be a fault in with the breaker as well, you should check the breaker for loose wire or discoloring from heat.

Glen, first thing is Safety FIRST! I am sure you know that, but make sure there is no power to the AC unit. Then check the terminals on the compressor to the case. Any continuity is a shorted compressor. Check the wiring to the compressor for any chafing, wearing, burnt spots, etc. It is also possible the blower motor is the problem. It could be drawing heavy and when the compressor tries to start then it overloads the breaker.

If it trips as soon as it comes on cleaning won't help, with the power off remover the cover on the compressor so you can see the wires, take your ohm meter and put on lead to a bare copper line and the other to each terminal. If you get continuity remove all 3 wires and check the terminals agian, if you still continuity then look for a new unit because the compressor is grounded. This is the first check, if the compressor isn't grounded then start checking the start and run caps.

ok, I pulled cover and fan was tight. Spun it and freed up. Huh!!! Turned on power and no air coming out vents. Guess I was wrong about compressor kicking in. Went back up, unit buzzing and fan locked. Could not turn it. Sounds like fan motor to me. No grease fittings. I saw no capacitor.

The 5mf side of the cap is for the fan motor, if the fan motor will not spin freely it will not start. The cap is for both the compressor and fan. Try getting some oil on both ends of the shaft and try and work it into tbe bearing.

ok, i lubed shaft good. Turned very freely. had wife to turn on breaker and fan never moved and was locked solid. Turned off breaker and shaft motor turned then. Little stiff and freed right up. It warm too. Capacitor didn't buzz then. Had been one for a while when first checked and it was buzzing then.

If you are looking for the fan motor, take the number from the fan motor and search on the internet. I had a bad fan motor and found the motor at Amazon.com. Cheaper than the local appliance parts store. The shaft in the motor would bind up. I would lub it and it would work for a day or so and then quit again.

As long as you're going to keep using what you've got.. I would agree with Rif. For $10-$11 it's a VERY worthwhile upgrade to your C65V.

But my capacitor is duall 60/5. 60 for condenser and 5 for fan. Don't see where that unit would work. Anyway I don't intend to keep using it. Timing not right for mini split upgrade just yet. Need serious time off for this.

With a dual cap you would install the SPP6 in parallel with your current start cap rather than as a replacement. (Just information for others since you don't plan on keeping it for long.)
