Rated 5 out of 5 by 1reviewer.
Rated 5 out of 5 by This device cured a hard start problem on my RV air conditioner. I installed this as a replacement to the starting cap. and PCTR which had burned out. It's especially helpful when you're running on generator power and need to kick the third unit on. July 2, 2013
