Went to turn on unit for the first time this year and it is not working. I cannot provide much more detial than that. I was reading and it says there is two breakers; one at the electrical panel which I checked and one behind the unit outside which leaves me puzzled. There is a plug that when I pull it out it says on on 1 side and off on the other but there is nothing to ensure the unit is on or off. Any help would be greatly appreciated. Thanks

I can't find that particular model. There will be two breakers in the electrical panel.

The outdoor unit has a 240 volt breaker. The inside (air handler) may be 120 or 240.

The outside is usually just a disconnect. One would flip the pull out to off, especially if one covered the AC in the winter.
