Now remember. When changing the transformer your right there. Do a quick ohm check on to contactor. Get odd readings go out to contactor and ohm it out. Serves two purposes. 1 you are checking the wire for a problems and 2 your checking the contactor.
Same thing happened to me, but my question is why will it not blow the fuse? it only blows the Transformer... shouldn't the fuse pop first to save the transformer..
If the load stays under the fuese capacity but is driving the transformer hard continuously and making it stay really hot and then the relay finally eats it. I only think and I could be wrong but that's why the fuse does not blow. The transformer was not meant for constant heavy load and is being damaged over time. Because we know do a direct short and fues should pop because to much amperage draw because there is not enough resistance in the circuit.
Yeah my brand new transformer just smoked and made crackle sounds. Fuse was still good. I replaced my contactor for the heater inside the air handler..... But since I burnt up the new transformer...I'm going to replace the contactor in my outside unit

FROM CHICAGO GOOD JOB THANK YOU SO MUCH
New to electricity here. What would a good reading vs a bad resistance reading be on a multimeter be ?
IT DEPENDS ON WHAT YOUR TESTING EACH COMPONENT WILL HAVE A RESISTANCE VALUE
Great video thanks...
Good demonstration thank you.

@@mostlikelywedoitservices6926good job bro
Nice
bad video...get a tripod so you vdont have to use one hand...and explain where to move the selection dial on your multimeter....
