The relay has a black button it I push it will turn the fan. But, now the black reset will not stay in. When I push it in it works. Do I just need a new relay or whatever that unit is?

Starts, however it fails every few months. It intermittently just cranks and doesn't turn over. I believe it to be a fuel pump relay or a main relay. Which one could it be?

I replaced the contactor on outside unit it will not go on unless we hold the 2 button like things down. Once we let go it turns back off.. What could it be now

Everything turns on indoors except the outdoor condenser. It is only when I push down on the contactor that the outside unit turns on and cools perfectly, but it doesn't stay on. I suspect it's my relay or capacitor? Any suggestions? The relay part # is ICM205 it runs about $16 should I change this?

The fan and the compressor of my a/c do not work, it seems that the electric board is getting 24V in but it is not coming out to the contactor relay.
