Lately, i have been measuring voltage on the top of combo Run Capacitors that far exceed the voltage rating stamped on the Run Capacitor furnished with the Goodman A/C unit.
IE: Todays measurement :
Goodman 2 ton model CK24 unit . Rating of combo run capacitor : 370 v. Voltage as measured on top between common and Herm : 389 v. Unit was operating correctly and incoming voltage entering and leaving the Contactor was 245 v.
Over the last few weeks, ive measured even greater variances on Goodman A/C Combo Run Capacitors between common and Herm as well as common and fan .How come they didnt put in 440 v. rated Combo Run Capacitors ?? Ive also had quite a few Combo Run Capacitors blow over the last few years on Goodman ... most likely due to the higher voltage imposed on them , than what the rating is.
Anyone else running into this ?
