Split a/c unit not working
My nordynegibson a/c unit just quit working, one minute blower was on next nothing and condenser outside wouldn't switch on neither. Changed out capacitor and contactor switch on condenser , but still nothing. Getting power to the circuit card from inside unit but it appears that the thermostat is not switching condenser on. Checked power at thermostat... No power :-( but I have power going to the wires at the inside unit circuit board ( the same power is making it to outside unit. Changed thermostat but still nothing , also found my start capacitor on blower fan is pretty far gone ( top of unit pulling off when I was tugging at the wires )
I do not have a door cut off switch on inside but I do have a overflow cut off switch which I temp removed and spliced in a straight wire to bypass it in case this was an issue... Nope still no power to thermostat. I also checked transformer and I'm getting good power at both sides. So here is my question , is it safe to say that I have bad wires from circuit board of inside unit to thermostat? Or could it still be the circuit board ? What is the best way to rule out the circuit board ? I currently have a new blower motor capacitor on order but would like to troubleshoot the power issue as much as possible so when the shops open Tuesday I can go get what I need and fix this finally. |

I have a goodman split heating and air unit-right now I have no heat. When I turn the thermostat to heat the light does not come on-when it does work, the unit makes a humming sound and blows out cold air. Please help-i hve a 2 yr old son. It's cold. Thanks
It worked fine all summer until last few months. When I have it to cool it blows air but not cold air. Now that I want heat it blows cool air and not hot air. It took it 30 minutes to heat my 1000SF home from 64 degrees to 65 degrees. What could be the problem?

I would like to say this website was very helpful, I learned a lot. Now for my question, I installed a split unit everything works, except the fan. All the wiring to the unit is correct, I had the assumption that the fan turned on after the unit got hot, but after running it for a while I found out...
Hi my a/c split unit will not run, it has two capacitors for the fan units, and following power problems and a possible surg of power back on. The 240 volts are OK on the supplies, but I also have 240 volts at the Nuetrals too, is this correct.
