A/C Problem

I have a Coleman unit made by Airxcel Inc. roof mounted. Last summer I had a couple issues where it would not power up when called for. Moving the stat back to off the back on a couple times and it would power up. Once running, it cools fine. So in my mind, it acts like the relays aren't pulling in, or perhaps capacitors.

I contacted Airxcel with the model and serial number and was sent a parts diagram. In that diagram I find the capacitors, which I will replace. But, I don't see relays. I can't believe there isn't a relay that would take the low voltage from the stat and through contacts power the fan and compressor.

Any ideas?
