I bought the capacitor mentioned in #8, above to test out.Let us know how it works out
So far, the wattage on the motor has been within the rating on this long run of very hot days.
I wasn't sure about heat versus such a physically small unit, so I mounted it with an air gap behind it for natural circulation. Will it help? I don't know. A k-type thermocouple taped to the case shows it operating at ambient of the enclosure.
