Customer Question

My condesnsing unit will not run.
JA: I'll do all I can to help. Tell me a bit more about what's going on so we can help you best.
Customer: The thermostat will start the furnace but not the condesnsing unit. I can manually run the contacts at the condensing unit and it will tun but i dont see any voltage coming to the coil to make it close.
JA: Is there anything else the HVAC Technician should be aware of?
Customer: Furnace is a Rheem RCFA-HM3617AC.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the HVAC Technician about your situation and then connect you two.

Hi, I will try to assist you with this. Did you check the voltage at the thermostat wires outside or at the contactor itself?
