I apologize...had site and computer issues. How was the wire?

Now we need to back track on the skinny wire with 2 conductors in it. This is the thermostat wire that runs with the copper pipes from the indoor unit to the outdoor unit. Now we know the 220v is ok.....now we have to find what is stopping the 24v. It could be damaged wire, an open low pressure safety switch....bad contactor etc...for now follow the wire and check for any damage from weed wacker or being pulled etc

Is there any way you can get a meter?

All we need is it to be capable of 24 volts ac.

I am afraid that will only pick up 120v +......the next step is to remove the 2 wires that run into the unit ...this is the skinny thermostat wire...it connects with 2 wire nuts....we wnt to take those apart and measure for 24v coming outside.

Let me check the archives
