This isn't exactly pool related, but with as many people out there with all kinds of diverse backgrounds - I figured I'd try here first. Please move/delete if needed.
But my A/C compressor went out yesterday afternoon, so my pool is now the most comfortable place on my property, lol. Got home from work and the temp inside was 85 F...sweltering. My thermostat is a digital/programmable kind. When it is set on "Auto"....the blower/fan/handler whatever it is does nothing. When I set it to "on", the blower cuts on...but does not cool at all. So, with the blower on...I went outside to check the compressor. It was off. I checked and reset all the breakers...all good - the line has 240 going into the unit. The contactor is suspect though. If I manually push it in, the compressor cuts on just fine. So I googled it, and I'm supposed to have a 24v reading on the two side terminals of the coil from the wires coming from the thermostat. I got nothing. I even disconnected the thermostat wire from the coil and tested them then, and I still got nothing. So I followed the thermostat line back to the blower where the current is sent from - and I'm reading 24v there.
Originally, I thought it was the coil on the contactor...but after thinking about it - It's gotta be something else if I'm reading 0 from the outside thermostat wires, right? Does anyone know if there's some kinda cut off switch...like a pressure switch, that'd cut off the voltage from the thermostat wire in case the pressure got too high? And would how close to the unit would it be?
In my other house, the A-coil froze over and I had to let it thaw out - then cleaned the fins really good on it. Could this also be a cause too?
Thanks in advance!
