My condensor fan capacitor burst!


During the night my condensor fan run capacitor burst. The fan motor & the capacitor are one year old. I found the unit not running and I believe the compressor was tripped with a thermal overload. I had another run capacitor. ( the burst one was 7 Mfd I put in a 10 Mfd, both 370 volts). after enough time to cool down it's running normally.

Anyone have any experience that might explain the problem?

You should install 7MDF.

Swelling or bursting is pretty common when it gets this hot out.

Long story short.

I bought a Turbo 200 Universal Replacement Motor Run Capacitor this morning because the A/C quit early evening and that's what I needed last time. Mine's a 55/7.5 mfd round dual type. Rep said it very versatile in that it can be modified into almost any size capacitor by using supplied jumpers on terminals. It was not difficult to set jumpers. Turned out it was not my problem this time. My unit is again running fine however. It was a short in old supply wiring.

My neighbor seemed upset this pm, just staring at his A/C unit which had blown its circuit. When reset, fan motor got very hot but would not turn on nor would compressor. And it smelled like a blown capacitor. It blew badly but stayed in its harness. Where to get a 40/5 mfd capacitor on a Saturday late afternoon in very hot NJ?

Seems if I reconfigured my now surplus Turbo 200 we could get his A/C back in no time. Which we did. Magic.

Impressive. Perfect for anyone with multiple A/C units of different sizes or for the trade. I can't vouch for reliability but it certainly worked in a pinch.

Best 'tool' to start such a project? A pad and pencil to write down which wires went where on old part.

Do NOT leave the 10 Mfd in or it will damage the motor.

Expensive to use as replacement but very nice for emergency. Must have item
