If you have a clamp tester, operate the unit with the clamp tester and check the current reading. If the current reading is normal but the reset button is tipped then there is something wrong withe power plug reset button. But if the current reading is higher than the name plate rating then there is something wrong with the unit.

transformer has just 4 leads. 2 for primary which is your 110 volts and 2 for secondary which is supposed to be 24 volts ac. if you splice the two secondary wires coming out of your transformer, you should be able to get a 24 v ac there.
the box that you are referring to could be a fire controller that in case of fire, it would shut off the fan and the compressor outside.
tnx 4 using fixya,

SOURCE: Amana PTAC cannot be turned on.
sound like a thermister problem, however this may also be a circuit board problem, the system is controled by the outdoor board, check to see if you have a blown inline fuse in the outdoor unit, it will be under a red case in one of the wires.
