This new Hi-Efficency Rheem furnace and A/C was supposed to save me from
problems like this...... :^(
Came home from work today, and my month-old system was blowing warm. 93+
furnace, 13 SEER A/C, all new hardware, has been working fine, including
over the 90-degree-plus weekend just completed. Inside blower runs, no error
messages on fancy thermostat, no tripped breakers or open fuses. Outside box
does NOT spin, and no temp difference in the 2 lines leading from inside to
outside. Compressor lockup? Coolant leak? Something obvious I am missing?
Yes, I will be calling vendor in the A.M., assuming I don't sweat to death
overnight, or the night monsters don't carry me off through the open windows
tonight.
Sigh. Ain't nothing easy....
aem sends...

I don't think a compressor failure or refrigerant leak will stop the
condensor fan (outside unit) from running although I suppose there could be
some with fancy electronics that tell it to shut down. So two likely
possibilities: No power to the condensing unit (despite your checks). Or
the thermostat isn't telling it to turn on whether due to a problem with
the 'stat or settings or the control wiring to the condensing unit.

Plain old unfancy units have pressure switches that shut the unit down from
overpressure on the discharge side, underpressure on the suction side,
and/or overtemperature.
Look for a reset button on your compressor.

Shut down the whole unit? Good to know. Thought only the compressor would
shut off.

Most 'unfancy' units don't have high pressure / low pressure switches,
but instead rely on the compressor overtemperature switch.
