Does AC Softstart void Warranty?

NEVER had this type question in 44 years. BUT, I DO modify some of my equipment under warranty. IF I would ever have a problem, I would remove that added part before taking it in for warranty service. Never had a problem under warranty for those times I added a part. I had a start capacitor fail on my Home AC system. I replaced it, to get cooling until the Company could come out and diagnose and fix. Before they showed up, I removed MY new capacitor and installed the defective one. Did NOT tell them what I did, just like you, did not want to get in a problem with ME touching the system under warranty. Doug

Here's the problem with soft start caps; If the original cap dies while the AC is running, rather than stopping like it normally would the AC will continue to run on the new cap and destroy the compressor.

Ones I've installed have a thermistor or other cutout on the soft start connection so it opens after a short period of time, and only leaves the run cap in the circuit. Or the motor may have a centrifical switch that keeps the start cap out of the circuit once the motor gets up to speed. I've seen both schemes on motors with a start and run cap.

In fact my current coleman =AC units have start and run caps installed from the factory. Same as an aftermarket, the start cap drops out of the circuit after startup and won't be energized again till a stop and then start occurrs.

Warranties are usually void if any work is done by a non certified person.

I'm an engineer myself and probably older than you. Professionally, I guarantee what I do. I don't guarantee/warranty what you do to it. (modifications) As far as I'm concerned, now, it's your design, and that's on you. Please don't call me back complaining that your design doesn't work. It's that simple.
