Get up on the roof and take the cover off the unit. Hold your hand on the compressor while someone turns the thermostat to cool and see if you feel the compressor try to do anything. Or you could use a volt meter to see if the compressor is getting any power. There are three leads to the compressor - common, start and run. Look at the wiring diagram to determine which is which and put your leads on common and run to see if there's any power going to the compressor. Common is the neutral wire. The run wire comes from one of the terminals on the run capacitor. You'll have to use the wiring diagram to figure out which wire that is. There's probably a relay on the control board that has to be energized by a signal from the thermostat before the compressor will start if you're not getting power to the compressor.
Thanks for the input everyone. I just got home from Florida to34 degrees this morning. The Ventana is in the heated garage but I will wait till it warms up to check it out. Ken
I took the cover off and the insulation cover off but there is a black plastic cover over the compressor. It has several tabs around it. How do the tabs release? I do not want to break any.
