Hello,
I have 3 5-ton units that are well fed. Units have been off for a couple of months. 2 of them are running fine but 1 is not. The blower comes out, the electronic water valve is opening ( which i have had to replace so many time already) but the Y2 light on the control bulb is not lit and the compressor is not coming on. Called the tech but its going to be a while before they can come. And its getting cold. Any ideas what i can look at to figure out why Y2 isn't lit? I've had to do most of the servicing on these units of the years as getting a tech that knows what they are doing is difficult.
thanks
