A/C will not do anything

Our first time to try a/c in 73 soverign. NOTHING. We are hooked up with
an extension cord (14) from the house. Unit is a Penquin. Any suggestions will be gratfully excepted.

Jill, if your trailer has a microwave oven, the trailer may be wired so that a hidden switch enables you to use either the microwave, or the A/C, but not both at the same time. The 30 amp supply is not sufficient to run both simultaneously. In our trailer, the switch is in the locker above the stove, and it is labelled for microwave in one direction, and A/C in the other switch direction.

I second Nick's suggestion. First, look in or below the overhead cabinets above the sink and stove. Often there is a switch that looks just like a toggle light switch in your home. One direction allows operation of the microwave while the other allows you to operate the air conditioner.

'73 = Microwave?

I would think it would be an after-market modification, if it had one....right?
Not likely it was built-in with a switch and '73.

On mine there are two thermostats. One up front for the heater. The second is for the a/c in the middle near the beds. They both have switches. The front thermostat controls power to the a/c and heater. I still get confused.
Circuit breakers are in the back by the toilet in the closet.
A light power supply line will cause the unit to pop circuit breakers in the supply and trailer.

You definitely need a 10 gage extension cord. You should also have a voltmeter to see that the power is actually reaching the AC. Without the meter it will be difficult to trouble shoot your problem.
