I am am sorry for the apparent consternation. I did not ask what what terminals and colors. I confirmed. It was to steer you from your thought of the O terminal. There is NO question regarding wiring.
If you read my response it ended with a pertinent question.
"Does the AC just NOT run under 73"? But I will clarify..
Does the ac run ok over 73? At 73? And just not lower than 73?
As far as apologizing for a potential rude response, I am not offended at all.
I have dealt with the public for over 25 years as a State Licensed Contractor in 2 states. When people call me it is not to chat about the day. Something is broken or amiss.
There is nothing like a conversation with a customer n 100F with high humidity with a defective ac unit and the part takes a day or 2 to arrive.
AND those calls are over much more than $16
I have no issue leaving this open indefinitely so proceed at your own pace and ask what you need but be specific.
EX- It runs at 73 and above with no problem. But when it hits 73 on the thermostat the ac shuts off. Heat runs fine______ to _______. So at this point the question is why does my ac not cool lower than 73?
If you choose to close this request and be refunded the entire $16 just request so and I will forward to customer service.
I f you wish to continue just answer the question I asked in first reply and we will work toward a resolution.
