I would have to get my book out to be able to tell you the exact specs, but this circuit board will lock out either one or both stages if 3 consectutive start attempts per stage fail, thus the reason why the infinity stat showed a code, so therfore I highly doubt it was that long. Unless carrierdan kept reseting it which is possible. I could be wrong, but lets just say the compressor were to try to start with a bad cap 300 times. The overload circuit breaker inside the compresser will trip out long before you get the windings to a lethal temperature. I have actually done this to a compressor I cut open which was only a 110v window A/C compressor and or course the circuit breaker was external. I crimped the discharge tube to make it act like it was starting against pressure. The valves would actually bleed down eventually. Even 300 times as long as the circuit breaker is not welded shut the windings should still be unharmed.
Pressing both contactors though would be like holding a screwdriver across two battery terminals. Instantly red hot.
